The Best Whole House Water Filters to Improve Water Taste & Odor

Writen by Ronald Brown

Fact checked by Natalie Bridges

Do you want to remove water contaminants that would otherwise make you and your loved ones sick? You might want to invest in the best whole house water filter.

best whole house water filter

This filter works effectively in ensuring that drinking water is safe from harmful chemicals, impurities, and other contaminants. However, choosing one from what is available can be tricky.

Before getting into the reviews, let’s go over a few essential factors you should not overlook when buying a whole-house water filter. After all, knowing what to look for will make it much easier to narrow down your choices.

  • Flow Rate: Water filters should not prevent you from enjoying a sufficient water supply. Hence, the amount of water passing through the filter and to the faucet matters. As a rule, a water filter with a higher GPM rating would be preferable, but you can use a flow rate calculator to learn the recommended size.
  • Filter Life: Some whole-house sediment filters only last 2-3 months before requiring a replacement. Meanwhile, carbon filters typically last up to a year. Everything depends on the filter’s capacity. A 200,000-gallon filter should last longer than a 100,000-gallon unit, provided all other parameters are equal.
  • NSF Certification: Manufacturers can claim almost anything to bolster their products. As far as water filtration is concerned, you should be mindful of the water filter’s NSF certification because it guarantees the removal of specific contaminants, such as lead or mercury.
  • Price: Big-name brands, such as Whirlpool, Aquasana, GE, and 3M, command a hefty price tag. Meanwhile, unknown brands are more affordable, despite having the same performance and quality as leading brands. Cost becomes an issue for budget-conscious families.

Here is a guide to help you select the right one for your needs. If you’re ready, let’s get started with some reviews.

Top-Tier Whole House Water Filter Reviews

1. DuPont WFPF13003B Filtration System

Most homes only need a basic sediment filter to give them clean water. If you are one of these families, you might consider the DuPont WFPF13003B. It is a water filtration system perfect for small homes and offices.

It is worth noting that the product is not a whole system. The company designed it as a universal sediment filter block to connect to your existing water filtration system. It is efficient enough in removing large water contaminants, such as silt, scale, rust, sand, dirt, and other debris. You get clean and safe water every time you open your faucet.

The removal of sediments also protects your washing machine, water heater, dishwasher, and other water-using appliances. It extends the service life of these appliances and fixtures, so you get to save money from purchasing a new water appliance.

The system works with both municipal and well water systems. It is not surprising many households consider it the most useful well water filtration system.

You may have to keep in mind that the product filters sediments only. It would be pointless to assume that it will reduce total dissolved solids. Also, it doesn’t protect you against microorganisms. It would be top-rated if you have a separate system for that.

Installation is straightforward. However, I urge you to consider getting a professional to eliminate the risk of leaks. It would help if you had a perfect fit of the connections to ensure a leak-free system.

While the DuPont WFPF13003B is only a sediment filter, it remains a good addition to an existing water filtration system. It is also the right choice for households that only want to address sediments in their water.

What We Like
  • Recommended for small households and offices
  • Reduces dirt, scale, silt, sand, and other sediments
  • Works with municipal and well water systems
  • Extends the service life of water appliances and fixtures
  • Installation is straightforward
What We Don’t Like
  • Only reduces sediments
  • Leaks if installed incorrectly

2. iSpring WGB21B Filtration System

Many families want a system that can deliver safe and clean water for the whole house. That is why many consider the iSpring WGB21B the top-rated home water filtration system. It may only have two filtration stages, but they are more efficient than other systems.

The whole house filter features an activated carbon filter and sediment filtration media. Both components work to provide you with sediment-free and great-tasting water.

Water passes through the sediment filter to remove large particles. Dirt, silt, scale, and rust will never pass through the second stage. The product clarifies water as it moves through the activated carbon block. Here, the water receives a special treatment that makes it more pleasant to smell and taste.

What is surprising is the system’s flow rate. Most products tend to reduce water flow significantly. Not this water filter. It can provide a continuous water flow of up to a quarter of a gallon per second.

Installing the system is hassle-free. You take it out of the box, get a few tools ready, and have the system installed within minutes. The manufacturer pre-assembled the filter before delivery, so you should have a little problem setting things up.

At 50,000 gallons, the filter’s capacity is not ideal for large households or families with heavy water consumption. They may need a system with a larger filtration capacity. It is also worth pointing out that the system does not affect dissolved solids. You may need a reverse osmosis system for that.

I strongly recommend iSpring WGB212B Whole House Water Filter to families who want a simple yet effective system of removing unnecessary elements from their water.

What We Like
  • Improves water taste and odor with its carbon filter
  • High water flow rate for optimum water use
  • Removes dirt, scale, and other large particles
  • Pre-assembled for ease of installation
What We Don’t Like
  • Limited filtration capacity
  • No effect on total dissolved solids

3. Aquasana EQ-600 Filter System

Homeowners want a water filtration system that will last many years. Aquasana has the solution. The brand’s EQ-600 Rhino Whole House Water Filter is durable and will serve your family for up to six years. The filter’s service life can save you money on frequent filter cartridge replacements.

The Aquasana whole house filter features a high-performance carbon filter media and a copper-zinc KDF filtration media. The filter combination removes up to 97 percent of chlorine, and the system has the appropriate NSF certification to give you the confidence you need in using this product.

The copper-zinc membrane also prevents the growth of algae and bacteria and gives your household safe water for different uses. Drinks taste better. Dishes are more delectable and sumptuous. Hard water stains are a history. You will also notice an improvement in your hair and skin during bath time. Clothes and dishes smell nicer, too.

I like the filter’s up-flow, dual tank design. It makes for a more efficient filter system by preventing clogging. The design also increases water contact time with the filtration media. The increased contact time allows the system to remove more contaminants, such as mercury, lead, chlorine, pesticides, and herbicides.

You will also like the system’s no-draining, no-backflushing design. Maintaining the unit’s optimum operation should be hassle-free.

While the whole house water filter has a long lifespan, its pre-filter and post-filter elements require frequent replacement. The company recommends replacing these components once every 3 months. Additionally, do not expect the system to reduce total dissolved solids.

I recommend the Aquasana EQ-600 Rhino to anyone who wants a durable whole house water filtration system. It effectively removes many water contaminants to give you and your family the water quality you deserve.

What We Like
  • Extra-long filter cartridge service life for optimum savings
  • High-performance filtration media
  • NSF certified to reduce up to 97 percent of chlorine
  • Prevents the growth of algae and bacteria
  • Unique up-flow, dual tank design

What We Don’t Like
  • Does not reduce total dissolved solids
  • Requires frequent pre- and post-filter replacement

4. Express Water WH300SCKS Water Filter

People who want a top-quality hard water filter whole house system should consider the Express Water WH300SCKS. It is a system designed especially for households that have high water hardness levels.

Not only does the system remove heavy metals and sediments, it is also capable of removing some microorganisms, such as fungi and viruses.

The system includes three filtration canisters with different filter media. The first stage removes sediments and other large particles.

The second stage features KDF media that changes the electric charge of water contaminants, rendering them harmless. It also creates a hostile environment for microorganisms, where viruses, fungi, and algae cannot thrive.

The third stage involves activated carbon that neutralizes odor and bad-taste chemicals.

The system can remove more than 80 contaminants, affording you clean, fresh, and safe water every time.

You will also like the inclusion of a stainless-steel frame. It stabilizes and secures the system wherever you decide to install it. The water flow rate is also superior to other systems. You can enjoy up to 15 gallons of water per minute. Use it for bathing your dogs, washing your car, or even doing laundry.

While the system’s filtration performance is superb, I wish its capacity was larger than 100,000 gallons. It would make filter replacement more economical.

Speaking of filter replacement, the system has one of the most straightforward processes for replacing the filter cartridge. There is no need to call a professional. Installing the system will require a plumber, however.

The Express Water WH300SCKS’s superior filtration performance makes it the right choice for homes that depend on wells for their water. It effectively removes unpleasant odors, tastes, and other contaminants to make water as safe and clean as possible.

What We Like
  • Effective against water hardness
  • Reliable filter media for improved water filtration capability
  • Removes more than 80 contaminants
  • Easy to replace filter cartridges for hassle-free maintenance
  • Solid stainless-steel frame for strength and stability
  • High water flow for optimum water use
What We Don’t Like
  • Low filtration capacity
  • Requires professional installation

5. Culligan WH-HD200-C Filtration System

The Culligan WH-HD200-C is a clear winner if you base your buying decision solely on the number of positive whole house water filtration system reviews. Many households love its simplicity and filtration performance. It is also compact, unlike other systems on the market.

The system is ideal for households that have old and rusty water pipes. Rust and other debris can ruin water quality. They can give water an odd taste or even an unpleasant smell. The water filter addresses this by removing as many sediments and other large particles as possible. Silt, dirt, and sand will no longer pester your daily water consumption.

What I find amazing about this filter is its sump construction. It is transparent, giving you a clear idea of how the system works. The unique design also makes it easy to monitor the filter’s status.

If you fail to monitor the unit, its filter life indicator will. You will know exactly when you need to replace the filter cartridge.

The company employed the services of WQA to test and certify the filtration performance of its product. This gives you a measure of relief, knowing that the system works.

It is important to point out that the product only serves as a sediment filter. It will not remove dissolved solids or absorb odor-causing chemicals.

However, it can still reduce chlorine and sediment-related odors and tastes. You can also replace the filter cartridge to make your filtration more efficient. For example, finer sediments require a finer filter.

The Culligan WH-HD200-C is the right choice for anyone who is concerned about sediments in their water, making it a reliable whole house water filter for well water.

It can also be an exceptional addition to an existing water filtration system for comprehensive and efficient water contaminants removal.
What We Like
  • Compact, unlike other systems
  • Removes sand, dirt, and silt from water
  • Filter life indicator for more efficient maintenance
  • Replaceable filter cartridge for filtration versatility
  • Transparent filter sump construction
  • WQA-certified for performance
What We Don’t Like
  • Works only as a sediment filter

6. iSpring WGB32B Filtration System

The iSpring WGB32B is a whole house carbon water filter that features two kinds of filtration media. The combination allows you to enjoy safer and cleaner water for the entire family.

The system’s three-filter canister design may confuse some people. One of these canisters houses the sediment filter that removes large particles, such as dirt, rust, and other sediments. The remaining two canisters contain carbon filter blocks.

The first of the carbon filter blocks removes chlorine, volatile organic compounds, and harmful chemicals. It also improves water clarity, odor, and taste. The second carbon filter block eliminates any residual water contaminants.

The three-stage filtration process gives your household clean and safe water for multiple applications. Bath times are more enjoyable. Washing the car is more fulfilling. Cooking a fantastic meal becomes more pleasant. It helps that the system has certification from a reputable third-party testing organization.

It is also worth mentioning the system’s minimal effects on water flow. It can provide your house with up to 15 gallons per minute. Everyone in your family will have a sufficient water supply.

Most complaints I read have something to do with its tricky installation. Some say the system tends to leak, even after following an installation instructional video.

I recommend getting in touch with the company. They can provide you with more accurate instructions on how to install the system correctly. It is your only way to ensure a leak-free whole house water filtration system.

I wish the company had designed a more durable filtration media. While 100,000 gallons may seem huge, it may not be enough for households with heavy water consumption. The filter should still last a year or so of average use.

iSpring WGB32B is a wonderful choice for households with average water consumption. Its product support is superb, and its filtration performance is commendable.

What We Like
  • A three-stage filtration system
  • Two filtration mechanisms for better efficiency
  • Minimal effects on water flow
  • Excellent support for DIY installation
  • Tested by a third party
What We Don’t Like
  • Faulty installation can lead to leaks
  • Lower filtration capacity than other systems

7. 3M Aqua-Pure AP904 Filter System

One concern that people have about whole house water filters is their effect on water flow. Some systems tend to reduce water flow significantly. The 3M Aqua-Pure AP904 addresses this concern by giving you a more efficient water filtration system.

Most brands can only provide 15 GPM. Capable of delivering up to 20 gallons per minute, the 3m Aqua Pure water filter system is ideal for medium to large families. You will never run out of water, even if everyone in the family uses water simultaneously. Many homeowners who value high flow rates consider it the most suitable whole house water filtration system.

The system’s main function is to prevent sediment build-up. Silt, scale, dirt, and other debris will never bother you again. You no longer must put up with the odd smell of chlorine or its annoying taste. Brushing your teeth, taking a shower, and cleaning your stuff will also be more rewarding because of the system’s remarkable sediment and chlorine removal capabilities.

Filtering sediments also improve the working condition of your water appliances. Water heaters, dishwashers, and washing machines will operate optimally. You will also not worry about buying a new water appliance soon.

I like this whole house water filter design. It makes installation worry-free. Replacing the cartridge is also hassle-free as there is no need for tools or touching the filter media.

On the downside, the filter’s benefits come with a heftier price tag than other systems. People would not mind paying the premium if the filtration capacity was more than 100,000 gallons. Sadly, this product can’t handle that much water.

The 3M Aqua-Pure AP904 is ideal for families that want more water flowing out of their water fixtures. It improves water quality without causing too much fuss during its operation and maintenance.

What We Like
  • Removes sediments and neutralizes chlorine odor and taste
  • Higher water flow rate than other brands
  • Extends the service life of water fixtures and appliances
  • Effortless filter cartridge replacement
  • Installation is not stressful
What We Don’t Like
  • More expensive than the competition
  • Modest filtration capacity

8. iSpring WGB22B Filtration System

A whole house water filter comparison between the iSpring WGB21B and the WGB22B shows that both systems are essentially the same. They only differ in the size of the filtration media.

The WGB22B filter cartridge is 10 inches longer than that of the other model. The additional size translates to improved water filtration capacity.

Another distinction of this product is its chlorine removal capability. Its two-stage filtration system removes up to 99% of chlorine. Other systems can only eliminate about 90 to 95 percent of the element.

This whole house filter also has a more reliable sediment filtration mechanism. It can remove up to 95 percent of rust, scale, debris, dirt, industrial solvents, herbicides, and many more.

Its filtration performance has the appropriate certification by a third-party laboratory. You can rest assured that this system’s filtration capabilities conform to NSF and ANSI standards.

You also will never worry about reduced water flow. The system ensures you get an adequate water supply, regardless of demand.

While this filter’s capacity is higher than some models, 100,000 gallons is hardly what many consider the ideal filtration capacity. However, it should still be sufficient to allow for continuous use of up to a year or so.

It is also worth mentioning that the system does not address dissolved solids in your water. Do not be surprised if you still have high TDS results after installing this system.

Nevertheless, the iSpring WGB22B remains popular among households that want a reliable sediment and chlorine filter system. It will not affect your water flow. Best of all, you and your family will enjoy all the benefits of filtered water.

What We Like
  • Removes more chlorine than other models
  • Removes up to 95% of rust, scale, herbicides, and more
  • Cartridge is longer than the iSpring WGB21B’s cartridge
  • High flow rate for more efficient water consumption
  • Third-party laboratory-tested against NSF and ANSI standards
What We Don’t Like
  • Capacity isn’t high
  • No effect on dissolved solids

9. Home Master HMF2SmgCC Filtration System

The Home Master HMF2SmgCC is one of the well water purification systems that is growing in popularity. The system effectively removes chlorine, chloramine, and other water impurities by up to 95 percent.

The first-stage filter features four-gradient media that facilitates efficient contaminant removal. Most products on the market only have one or two layers, which may allow some particles to pass through. This filter’s multi-gradient filtration media never lets finer particles pass through its membrane. Its smallest hole diameter is 1 micron. Other systems have 5-micron holes.

The use of a KDF filter also improves the system’s purification capabilities. The filter creates an inhospitable environment for bacteria and fungi. While the system does not kill these microorganisms directly, it does control their growth. The water you get is as clean and safe as you expect it to be.

The ports are large, letting you enjoy high-pressure water delivery. You can use it for washing your car without worrying about hard water stains. It works with municipal water systems, too.

One downside I see about this product is its effect on the flow rate. Other systems provide 15 gallons per minute. This system can only deliver 10 gallons per minute. The flow rate should still be sufficient for most homes, provided members do not use water simultaneously.

The system’s steep price is understandable. However, there are products of similar specifications that you can get for half the price.

Despite these issues, I would still recommend the Home Master HMF2SmgCC to any household that wants a water filtration system for the entire house.

The design of the top-rated whole house filter not only removes heavy metals and sediments. It can also limit harmful microorganisms to give better water quality. This is exactly what this product does.

What We Like
  • Removes chlorine, chloramine, sediment, and other contaminants
  • KDF filter to control bacteria and fungi
  • Small-diameter filter holes and four gradients for high-performance filtration
  • Large ports for optimum water pressure
  • Compatible with municipal and well water systems
What We Don’t Like
  • Lower flow rate than competing brands
  • Available at an expensive price

10. Express Water WH300SCGS Water Filter

If you are looking for a dependable whole house water filtration system for well water, I strongly recommend the Express Water WH300SCGS.

The whole house water filter uses three filtration media to deliver high-quality water to your home.

The sediment filter rids water of large particles of at least 5 microns in diameter. The granular carbon filter captures chemical contaminants, including VOCs, insecticides, and industrial solvents. It also removes substances that leave an unpleasant taste and odor in the water. The third stage uses activated carbon to improve water clarity. It also removes pharmaceutical agents, chlorine, and total organic carbon.

Overall, the system can remove not less than 52 contaminants to make your water drinkable straight from the tap. The system has the appropriate certifications to validate its claims. That is peace of mind for you.

The filter’s design is worth mentioning. The solid steel frame allows you to secure the system on the floor without needing complicated mounting. Each filter canister for improved water quality also has its own pressure gauge. It makes system performance monitoring more accurate.

While the system’s filtration performance is nothing short of spectacular, it does not reduce the number of dissolved solids. Many homeowners think that the system can improve their water’s TDS levels. It does not. It would also be safe to say that the system has a higher price tag.

The Express Water WH300SCGS may be beyond the reach of the average household. However, if money is never an issue for you, this system is perfect. Its filtration performance is one of the most trusted. You will be glad to have this whole house water filter in your home.

What We Like
  • Removes at least 52 water contaminants
  • Three filtration stages for more efficient contaminant and odor removal
  • Individual pressure gauges for more accurate system performance monitoring
  • Certified to validate its claims
  • Solid steel standing frame for effortless installation
What We Don’t Like
  • More expensive than competitors
  • No impact on dissolved solids

11. iSpring WSP50 Sediment Water Filter

If you only read a single whole house water filter review, you may not be able to paint an accurate picture of the filtration performance of the iSpring WSP50. It is a pre-filter component that works as an important element of the iSpring WGB series of whole house water filters. While it works with iSpring products, it should also work well with other systems.

Unlike other products, this sediment filter features a high-quality stainless steel mesh filter. It is stronger and more durable than other mesh filters on the market today. You get to filter particles that are at least 50 microns in diameter.

What I find amazing about this product is its see-through design. The fine mesh filter tends to clog easily if your water happens to have a high level of sediment. The see-through design allows you to monitor the mesh filter’s status. You will know immediately if it is getting clogged or not.

A clogged mesh filter is not a serious issue in this product. It is completely reusable. All you need is a small amount of elbow grease to remove the filter from its connection. You can then spray the filter with a high-pressure water hose to flush it and remove the clogging sediment.

Depending on your water’s sediment level, you may have to perform frequent and regular mesh filter flushing. The good news is that you will never have to buy another filter until about two years after purchase.

The iSpring WSP50 is not a standalone water filter. It would be top-rated to use it as part of your whole house water filter.

What We Like
  • A pre-filter for an existing water filtration system from iSpring and other brands
  • Effectively removes sediments and other large particles
  • See-through housing allows for more accurate monitoring
  • Strong stainless-steel mesh filter for improved durability
  • Flushable and reusable filter design for better economy
What We Don’t Like
  • Clogs easily if used with high-sediment water systems
  • Requires regular and frequent flushing

Outdated Products

SpringWell Whole House Water Filter System (Outdated)

Many modern households want their water filtration systems to last many years. While filter canisters are durable, their filtration cartridges can only last about a year or two. SpringWell understands this concern. That is why the company developed its own whole house water filter system.

The system looks nothing like the three-stage systems we see in the market. You get a single large tank instead. It houses two filtration media that work in unison to deliver great-tasting and clean water. A small pre-filter media removes sediments before the water gets special treatment in the large tank.

There is a KDF media that removes contaminants like pesticides and herbicides, and improves the water’s taste and odor characteristics.

A catalytic carbon block completes the contaminant removal. It also aids in the removal of chemicals that give water a bad taste. Your dishes will taste more appetizing.

This model’s main advantage is its large-capacity filter. It can accommodate up to a million gallons, more than many other products. An average household with modest water consumption can expect the filter to last at least a decade. It should also be ideal for large families and households with heavy water consumption.

The initial startup cost of the system is higher than other brands, but I think it’s worth it, considering how long the filter lasts. What I am concerned about is its low water flow rate. Most systems offer an average flow rate of 15 gallons per minute. This product can only provide 9 gallons per minute. Good thing the system is effortless to install.

I believe the SpringWell system is the best whole house water filter money can buy. Its high-capacity filter should give you ample savings to offset the high cost of buying the system. Its chlorine removal efficiency is also noteworthy.

What We Like
  • Larger filtration capacity than many whole house water filters
  • Combination of a pre-filter, KDF, and a catalytic carbon filter
  • Reduces chlorine levels
  • Recommended for large households
  • Effortless to install
What We Don’t Like
  • High initial cost
  • Low water flow rate

What Is A Whole House Water Filter/ Who Is This For


Self-explanatorily enough, whole house filters do as they’re named – filter water for your whole house. For large households, these filters assure you have clean water before it even enters your home.

Because it’s installed directly to your primary plumbing system, water is filtered as it comes – providing filtered water for your kitchen appliances, showerheads, and even your toilets.

Many would consider whole house heavy metal water filters as low maintenance, as they only need to be checked up on every six months and be replaced with their own whole house water filter cartridge.

Whole house filters fall in between domestic and industrial appliances – which means it can handle the hustle and bustle of a crowded and busy home. Because it filters water for the whole house, clean water is distributed all over.

There’ll be no need to wait for turns in the kitchen for that glass of water – household members can access water anywhere in the house.

Additionally, a whole house water filtration system is built with other filter systems that make it effective against whatever questionable gunk that comes from your main water supply – while also providing soft water that’s friendly for your kitchen appliances.

Besides a water softener, it is usually equipped with a UV sterilizer, a carbon filter, and a sediment filter. A reverse osmosis system can also be paired with your whole house filter.

This is known to be one of the most effective water purification methods today.

Because they can be super tough against contaminants, whole house filters also work well with households that rely on well water.

Unlike municipal water, well water comes straight from the ground and hasn’t been treated with chlorine, making it susceptible to organic contaminants.

Thankfully, whole house filters with UV sterilization can kill various microorganisms and bacteria – including the ever-so notorious and diarrhea-causing E. coli.

In addition to removing bacteria, you can set your whole house filter to remove fluoride and chlorine. Consumer reports show that a whole house water filter is a worthwhile and long-lasting investment because of its efficiency.

How Does It Work

The ideal whole house filter system consists of multiple mechanisms that are tough against the contaminants, sediments, and overall gunk that can come with any community water supply.

A sediment filter, an activated carbon block filter, ultraviolet sterilization, and a water softener can be incorporated into a whole house water filter.

Whole house water filter cartridges are a sediment filter that clears out any dissolved soil, dirt, and scale from the water. These are either paper-based cartridges, metallic mesh systems, ceramic systems, or all these materials put together. Their main purpose is to make your water less cloudy, improving its texture and making it look clearer.

Ion exchange is also incorporated into whole house filter systems to soften your water. It does this by exchanging the magnesium and calcium minerals with salt using a resin bed. The process leaves you with soft water for your skin, hair, clothes, and kitchen sink.

You won’t have to worry about chalky scale stains sticking to your appliances and showerheads and having to descale your coffee maker and dishwasher constantly.

In addition to a water softener, the activated carbon filter layer in the whole house filter removes more solids and chemicals – especially chlorine.

While chlorine treats the water and makes it safer, it isn’t the most pleasant substance to drink.

A whole house water filter’s activated carbon filter removes chlorine and other chemicals – improving the smell of your water.

The leading brands of whole house water filters can effectively treat your incoming water, all without the use of electricity.

Certain models can come with an ultraviolet sterilization system that can eliminate viruses and bacteria. Whole house filters with UV filtration are a powerful tool against disease-causing microorganisms – including cysts, coliform bacteria, and E. coli.

What Are The Different Types Of Whole House Water Filters


There are a variety of whole house water filters available in the market. To find one that’s perfect for your home, it’s top-tier to know what you’re looking for.

Additionally, it’s also recommended that you know the quality of your water supply.

In most cases, you may need more than one type of filtration system for your home – as this ensures the best kind of water for your household.

An all-around whole house filter incorporates all the usual filtration methods such as activated carbon, and mechanical filtration, for odorless, top-tasting contaminant-free water.

A good all-rounder whole house filter will still leave the good minerals in your water while not compromising health and safety. To add to that good news, it won’t need any electricity to function and will only need to be replaced every six months.

Whole house water filters designed for well water usually come with a three-stage system that targets explicitly dissolved solids and bacteria unique to well water.

On the other hand, a whole house water filter that works is most acceptable for city water incorporates only two stages, considering that most city water supplies already have treated water.

These are also whole house water filter to remove fluoride and chlorine, commonly used on treated city water.

For many homeowners, soft water is vital for the household. If you’ve never heard of soft water, its main advantage is that it’s better for household appliances and will not dry out your hair and skin.

The top of the line whole house water filtration and softener system will utilize specially-made granules for the water softening process. Usually, these granules don’t have to be replaced and will be able to soften your water in less than a minute.

Meanwhile, a whole house heavy metal water filter is recommended for houses with rusty plumbing lines – as with the case of older houses. These whole house filters do better at removing rust particles and bits of heavy metals.

A whole house filter can also be installed with a UV disinfection system that adds an extra layer of assurance. UV sterilization works well against bacteria and harmful microbes, all while not affecting the smell and taste of your water.

Advantages And Disadvantages Of Using Whole House Water Filters

Water filtration systems come in many types. When it comes to convenience for the entire house, very few water filters can outclass a whole house water filter.

However, setting up such a system can also be expensive. That is why it is always a good idea to examine the advantages and disadvantages of a whole house water filter to determine if it is the right solution for your family or not.

The following are the main advantages of using a whole house water filter.


A whole home water filtration system can provide safe and clean water to all parts of the house that require water. You can have clean water in the kitchen, bathroom, garden, washroom, and other parts of the house without installing several systems.

More Efficient than Point-of-Use Systems

Whole home water filtration systems have a higher filtration capacity, making them more efficient in water contaminant removal. Many systems also have multi-stage filtration processes that allow more efficient removal of contaminants.

Requires Less Effort and Time to Maintain

Because there is only one system in the house, maintaining it should not be time-consuming. Maintaining several point-of-use systems can take you the whole day to complete.


You can build a robust whole house water filtration system by adding filtration components. For example, add a reverse osmosis filtration unit or even a UV treatment filter to your existing system to make water purification more effective.

Despite the advantages of a whole house water filter, it can also pose the following issues.

More Expensive

Whole house filtration systems can cost you between $200 and $10,000, depending on the system’s completeness.

Sediment filters are the least expensive. Unfortunately, they only filter large particles. Reverse osmosis water filtration systems are the most suitable, although they cost more. Multi-stage water filtration systems also require a premium.

You will also have to purchase filter cartridge replacements. Depending on your whole home water system’s filter capacity, you may have to buy additional filters every 1 to 10 years.

Many Require Professional Installation

Most systems require professional installation. Many whole house water filters need significant changes to your house’s plumbing. Adapters and connectors must fit correctly to avoid leaks.

Requires More Space

The whole house water filters are bulky. Small homes can still install this system by making some modifications to accommodate the whole house water filter.

Buying Guide


Whole house water filters are effective solutions for families that want to ensure safe cooking and drinking water for everyone.

Since there are many models on the market, it would be top-rated for homeowners to look at factors that can help them determine the right filter to buy.

Filtration Performance

A good water filter should be able to remove as many contaminants as possible. It should be able to remove lead, mercury, arsenic, and other harmful heavy metals.

It would also be a big plus if the product could remove pesticides, herbicides, pharmaceutical chemicals, and industrial agents.

It is often advisable to check the number of contaminants that a product can effectively remove. A unit with a filtration performance of 70+ contaminants is better than a product that can only eliminate 60 or so impurities.

Checking the percentage of removed contaminants also matters. For example, a product that can remove 99% chlorine is better than a unit that can only filter 95% chlorine.

It would also be wise to check appropriate certifications from reputable organizations to validate the company’s filtration performance claims.

Filtration Capacity

Ideally, you will want a whole home water filter that has a large filtration capacity. It defines the unit’s ability to remove contaminants continuously before needing a replacement. It also translates to better savings.

Impact on Water Flow Rate

Some homeowners dislike water filters because of their impact on the water flow rate. Choosing the wrong product can reduce your water flow rate by as much as 50 percent.

While many factors can reduce the flow rate, it is often wise to pick a water filter with a published water flow rate. You can compare the information with your average water flow rate.

A product is worth buying if it affects your water flow rate only minimally.

Availability of a Filter Change Sensor and Reminder

Water filters lose their filtration efficiency over time. That is why they have a filter capacity rating that describes the volume of water the filter can accommodate throughout its service life.

Unfortunately, monitoring the filter’s status can be challenging. A filter change sensor can simplify monitoring and facilitate a timelier filter replacement.


 A water filter’s style and finish should complement your kitchen aesthetics.

Frequently Asked Questions (FAQs)

Is whole house filter worth it?

Yes, a whole home water filtration system is worth every penny. Even simple water treatment systems that only remove sediments, chlorine, and a few other water contaminants are better than not having one.

The advantage of a whole-house filter is that it removes unwanted particles from the water going to all fixtures and faucets. You could drink from a garden hose without worrying about manganese, lead, mercury, and other heavy metals.

And if you get a whole house water filter and softener combo, you could also address hard water-related issues (i.e., rusting or corrosion in the plumbing and associated systems).

Interestingly, a Consumer Reports article says the value of whole-house water filters depends on a family’s needs.

To elaborate, whole-house filters are ideal for families that require sediment-free water for various purposes, from cooking and drinking to bathing. And if you need something for lead removal, a high-end whole-house filter should be your pick.

On the other hand, under-sink water filtration systems are suitable for households that only want safe cooking and drinking water. If you are like this family, a whole-house water filter is not worth it.

Where should a whole house filter be placed?

A whole-house filter should always be near the main water supply line’s shut-off valve before the large-diameter pipe branches into smaller sections.

Some homes have the main shut-off valve in a utility closet near the fence or gate, while most have it in the basement. You can follow the water pipes to locate the shut-off valve.

How many filters should a house have?

A single whole-house water purifier for home use is enough for a house.

However, note that the ideal product should have at least four stages or types of water filter, including sediment filter, carbon pre-filter, reverse osmosis technology, and carbon post-filter. This setup is sufficient to guarantee safe drinking water for homes.

What micron is most suitable for a whole house filter?

A whole-house water filter has varying filter cartridges for different purposes. Hence, they vary in micron size, depending on what the cartridge is for.

A 50-micron sediment filter is ideal for a surface filter. However, the inner one must be at least 1 micron in pore diameter. On the other hand, the top-tier carbon water filter for spring water should have at least 0.5 microns.

What are the most trusted whole house water filter brands?

There are different whole house water filter brands on the market. Here are some of the most trusted ones.

  • Aquasana
  • iSpring
  • Express Water
  • Culligan
  • DuPont

How much does a whole house water filtration system cost?

Despite it being already treated, your tap water supply may still contain some contaminants and bacteria. In fact, studies show that there are traces of sediment, chemicals, heavy metals, pharmaceuticals, germs, etc., in tap water.

Installing a water filtration system in your home helps remove the remaining substances and even improves the water’s taste and smell.

A whole home water filtration system connects to your home’s main water line. As a result, you can get treated water from all your water dispensers at home.

Water filtration systems differ in size, flow rates, lifespan, and other attributes.

Choosing one will depend on the water contamination level you have. As such, make sure to do a water test to determine the level before buying one. Once you know this, you can effectively narrow down your choices and choose one that suits your needs.

How much a house water filtration system costs vary, depending on the unit’s features. The more complex your system is, the more expensive it is going to be. As such, filter prices can go from a hundred dollars to a thousand or more dollars.

Besides that, you must also consider installation and shipping costs (if you are ordering online) to increase the price.

What size whole house water filter do I need?

House water filtration systems have a diverse and big market. You can find many different filters, with each one having features that can suit your needs.

As such, it cannot be easy to buy one, especially when you are a beginner. However, you don’t have to worry.

Before you purchase your house water filtration system, a rule of thumb is to conduct a water test first. Knowing this is essential since it will determine the system’s size, performance, and lifespan.

For example, if the contamination level is high, then a bigger whole home water filter might be more efficient.

A house water filter’s size hinges on two aspects: filter and port size. Larger filters boast a longer service and more water flow and pressure. Port size also matters since this affects the system’s flow rate and pressure.

Ideally, a 4.5” x 20” filter and 1” port size is sufficient for most homes. These measurements can efficiently treat a large water volume easily.

If you have a bigger house, you might need a unit with a higher flow rate and a bigger port. If this is the case, find a water filter with at least a 25 GPM flow rate and a 1.5” port.

How long do whole house water filters last?

House filtration systems catch sediments, minerals, and chemicals and remove them from your water. Over time, the system will clog up due to accumulation.

Once this happens, you need to replace the filter immediately. The longer you put it off, the more clogged it will be.

A clogged water filter has the danger of contaminating treated water as it can no longer collect and filter out sediments, chemicals, and bacteria. Moreover, it might even encourage microbe and mold growth in your filter, which can endanger you.

How long your house water filter will last depend on the volume of water used, contamination levels, and the filter’s size and capacity.

While filtration systems differ, all of them usually have pre-filter, carbon filter, and post-filters. You need to constantly monitor these three since they are responsible for the filtering process and need to be replaced.

Averagely, these filters have the following lifespans:

  • Pre-filter: three to six months
  • Carbon filter: one year
  • Post-filter: one year

How to clean whole house water filter?

House water filters are relatively easy to clean and maintain. For one, you will only need to check the system for leaks. If there are, find the leak and reseal the connectors.

You also must monitor the state and condition of the system’s filters. While water filter systems differ, they all have a pre-filter, carbon filter, and post-filter, which can clog up due to particles’ accumulation.

To clean them, here’s what you will need to do:

  1. Shutoff. Turn off the main water line, or if you have a valve installed, turn it.
  2. Remove. Take out the system’s water filters. Some filters come with plastic netting that keeps the paper piece in place. You’ll have to remove that netting to clean your filter.

Using a cutter, slice the netting’s edges and ensure you’re cutting through the filter paper. However, leave a small strip for easier tracking.

  1. Hose. Wash off the excess gunk of the filter.
  2. Thoroughly clean. After hosing it down, you’ll need to clean the filter’s inner parts. For a pleated filter, you can soak it in oxalic acid for 20 minutes. For the carbon filter, soak it in bleach and water for 5-10 minutes.
  3. Prepare to house. Before returning the filters to the system, you’ll need to clean the housing as this can also have bacteria. You can use a mixture of bleach and water to do this.
  4. Return. Return the filters into place and reinstall everything. Make sure all the screws and connectors are tight and connected to prevent leaks. Turn on the waterline after.

How to install and use?

Now that you have purchased a house water filtration system, it’s time to install it. These systems can be challenging to install, but it’s not impossible.

Here are the general steps on how to do it:

  1. Gather. Make sure you have everything you need to install at the installation site. Aside from the product itself, you should also prepare the necessary tools.
  2. Turn off. Shut off the house’s main water line and then drain the system of water. Doing this will lessen messes and prevent any accidents.
  3. Cut. Cut off the pipe section you need to take out. How large the cut depends on the water filter’s size. For example, a single-stage water filter requires a smaller length than the required section for a multi-stage water filter.
  4. Secure. Attach the filter’s bracket. Make sure that you do it well, as the bracket holds the system’s filters.
  5. Install. Put in the connectors that connect the main pipe to the water filtration system. To avoid leaks, apply a generous amount of food-grade lubricant or Teflon.
  6. Multi-stage filter. If you are installing a multi-stage filter, then you will need to link the different filters. Ensure that you tightly seal their inlets and outlets to prevent any leaks.
  7. Install. Lastly, attach the filter’s inlet and outlet valves. Make sure everything is screwed tight shut.
  8. Test. Turn on the house’s main water line and check the water filter system for leaks and other problems.

Once you’re done setting up the house water filter system, you are good to go. If you want, you can also opt to install a bypass valve to make it easier. The valve allows you to clean the system’s filters without turning off the main water line.

You can also install pressure gauges to monitor the water pressure. The gauges also help determine if the filters are clogged as water pressure drops when they are dirty.

Where to buy?
