The Best Faucet Water Filters for Kitchen & Other Purposes

Writen by Ronald Brown

Fact checked by Natalie Bridges

The best faucet water filter is a good choice for families that want unlimited and readily-available filtered water for drinking and cooking. Not only is this water filtration system efficient in removing water contaminants, it is also a good option for budget-conscious households. You can say goodbye to expensive single-use bottled water for your family.

The system does not require a complicated setup and operation. If you choose wisely, you can even improve your kitchen’s aesthetics.

In order to quickly identify the suitable faucet water filter, you’ll need to keep in mind some important factors. Otherwise, the product you purchase may not meet your requirements, despite being high quality.

  • Contaminants Removed: It makes sense to pick a product that can remove as many water contaminants as possible. For instance, a unit that eliminates up to 80 common water contaminants is better than a device that only removes 50 or 60. It’d also be helpful to carry out a water test to know what specific particles you need to filter.
  • Filter Capacity: Faucet water filters have smaller filter cartridges than whole-house water filtration systems. These products can only accommodate a limited volume of water before replacement. Pick a faucet water filter with a higher gallon capacity. For example, a 20,000-gallon unit is better than a 10,000-gallon device.
  • Flow Rate: The average faucet has a flow rate of 1 to 2.2 gallons per minute (GPM). You will want the water filter to maintain your faucet’s average daily flow rate. For example, if your fixture releases 1.5 gallons of water per minute, the filter must not reduce it to 1.4 GPM or lower.
  • Installation: Faucet water filters should be straightforward to install in any water fixture, requiring only the most common hand tools. DIY setups should also be free of leaks and other installation-related problems.

The trick is to get only the right water filter you can find. Do not fret. I prepared this article just for you.

Top-Quality Faucet Water Filter Reviews

1. Brita 35214 Water Faucet System

Brita is one of those water filtration system brands that modern homeowners trust. The company provides affordable and equally-effective products that deliver clean, safe, and great-tasting cooking and drinking water.

Many homeowners consider the Brita 35214 as the top-quality tap water filter. The faucet water filter contains a filtration cartridge that eliminates at least 60 water impurities, including chlorine, asbestos, and up to 99 percent lead. It even removes benzene and other particulates. Feeling more confident about the water you drink and cook with is easy with this unit in your kitchen sink.

The filter’s unique design also helps improve the water’s taste and odor. You will not get any of the odd chlorine smell from your water. Drinking should be more enjoyable. Making tea, coffee, and other beverages should also be more pleasant.

I like the product’s cartridge design. As one Reddit member says, the design allows for a toolless installation. There is no need to call a plumber or use fancy tools. Too bad the product does not fit spray and pull-out water faucets. It would have been nice if it did.

The faucet water filter is also not expensive. Thus, it is a desirable option for households that want to economize. Its 100-gallon capacity is less than ideal for households with heavy water consumption. However, it is perfect for the average household.

The Brita 35214 is the right choice for people who want an economical and reliable system to filter their drinking and cooking water. Its ease of installation and hassle-free operation make it a worthwhile investment for the modern family.

What We Like
  • Filters at least 60 water contaminants
  • Removes up to 99% of lead
  • Improves the water’s overall taste and odor
  • Does not require tools to install
  • Comes at an affordable price
What We Don’t Like
  • Does not fit spray and pull-out faucets
  • 100 gallon capacity is not ideal for households with great water consumption

2. PUR FM2500V Faucet Filtration System

Homeowners who want the best faucet water filter often choose the PUR FM2500V. It is an affordable, elegant, and effective faucet water filter. Serving safe drinking water to your family or cooking delicious meals is a breeze with this unit in your kitchen sink.

People love the filter unit’s filtration capabilities. It can remove at least 70 water contaminants to provide your household with safe cooking and drinking water. Its activated carbon filter removes 10x more water impurities than the top Brita pitcher can remove.

Including an ion exchange further improves the filtration performance of the product. Your family no longer needs to worry about lead and other heavy metals in your water. It is like a reliable faucet water purifier that gives you safe and clean drinking water anytime.

Inside the filtration unit is a patented MineralClear core that improves the water’s overall taste. There is an LED light, too, that notifies you when it is time for a filter change.

Unfortunately, the filter capacity is lower than other brands. The product can only filter 100 gallons before requiring a replacement. Nevertheless, its filtration performance outclasses many other faucet water filters.

The filter unit features a unique One-Click attachment mechanism. Installing it in your kitchen faucet should never pose any problem. The only downside is that the product does not work with handheld and pull-out water faucets.

On the bright side, the elegant finish of the tap water filter should complement your kitchen décor. It will never look out of place.

The PUR FM2500V is a dependable tap water filter. It is perfect for households that want only the safest drinking and cooking water for their family. You cannot ask for more.

What We Like
  • Reduces at least 70 water contaminants, 10x more than the top Brita pitcher
  • Ion exchange and exclusive MineralClear technology
  • One-click attachment mechanism
  • Features a filter change LED notification
  • Elegant design complements a kitchen’s aesthetics
  • Has an affordable price
What We Don’t Like
  • Incompatible with some water faucet types
  • Lower filtration capacity than other brands

3. Waterdrop WD-FC-01 Water Faucet System

Most faucet water filters have a modest filtration capacity of only 100 gallons. The Waterdrop WD-FC-01 gives you more than three times the capacity of these filters. Capable of giving you 320 gallons of filtered water, this filtration unit is the top-tier sink water filter money can buy.

The high filtration capacity of the product translates to a longer service life than other brands. Even households with heavy filtered water consumption will benefit from the product’s filtration capacity. You can cook more dishes and enjoy more glasses of filtered water than with any other brand.

The secret to the filter’s performance is its five filtration layers. A stainless steel mesh removes large particles. A pre-sediment filter removes solids not removed by the steel mesh. The activated carbon filter, which bears most of the filtration performance of the unit, can eliminate chlorine and other heavy metals by up to 94.2 percent.

The advanced filtration layer further reduces any remaining chlorine and lead. The post-filtration layer then strengthens the filtration performance by removing rust, small particles, and suspended solids. The result is clean, safe, and better-tasting cooking and drinking water.

The company adheres to the standards set by both ANSI and NSF to give you a safe and efficient water filtration product. I also like its high-flow design. Most on faucet water filter products substantially reduce water flow and often take minutes to fill a 500-mL water bottle. This product lets you fill a half-gallon water jug in a minute.

On the downside, you may have to record your water usage because it does not have a filter change sensor.

Nevertheless, Waterdrop WD-FC-01 is the right choice for households that want excellent value for their money. Both its filtration performance and capacity are superb.

What We Like
  • High filtration capacity for less frequent filter replacement
  • Five filtration layers for improved filtration performance
  • Certified by both ANSI and NSF for greater peace of mind
  • High water flow design for more efficient water use
What We Don’t Like
  • No filter change notification

4. Culligan FM-15A Faucet-Mount Filter

Here is another faucet water filter that is perfect for practical households. The Culligan FM-15A Faucet Mount Filter provides up to 200 gallons of filtered water before needing a replacement. You can enjoy safe drinking and cooking water for up to two months, even if you have heavy water consumption.

The filter’s long service life translates to a better economy for budget-conscious households. Replacing the filter cartridge is less frequent, and your family can use the savings to buy other important items for everyone to enjoy.

The product’s filtration performance is not bad, either. It can remove lead, chlorine, and other heavy metals. The International Association of Plumbing and Mechanical Officials (IAPMO) tested and certified the product to ANSI standards. It is comforting to know that the water you drink or cook with does not contain Giardia cysts or Cryptosporidium spores. The water looks crystal clear, too.

Not only is the product effective in removing chlorine and lead, it can also reduce the levels of atrazine, lindane, and class I particulates. Meals will taste better. Juices will prove more refreshing.

I also like the filter’s high water flow rate. Its design allows the filter to provide sufficient water for all your needs.

While the filter’s performance is superb, I wish the product had a more robust housing. The plastic neck that connects the filter unit to the adapter tends to break easily. Replacing the filter cartridge also tends to be more challenging than other brands.

Despite these concerns, I recommend the Culligan FM-15A to anyone who wants a longer-lasting filter than other brands. Its filtration performance is also commendable.

What We Like
  • Reduces water contaminant levels for safer and better-tasting water
  • Long-lasting filtration system for better economy
  • High water flow rate for optimal water use
  • IAPMO certified design for peace of mind

5. PUR PFM400H Faucet Water System

PUR continues to amaze modern homeowners with its high-quality, high-performance faucet water filters. The PUR PFM400H is the brand’s top-selling unit that offers an excellent combination of stylish design and reliable filtration performance.

The PUR faucet water filter features many technological innovations we have come to love about the brand. It removes at least 70 contaminants to give you clean, clear, fresh drinking and cooking water.

Pesticides, lead, pharmaceutical agents, heavy metals, and sediments will never pass through the product’s ingenious filtration mechanism.

I like the inclusion of MineralClear technology because it guarantees better-tasting water. You will never taste chlorine in your water or in any of the beverages or dishes you prepare. It is like having high-quality bottled purified water but without plastic water bottles.

Installing the filtration unit in your faucet is easy, since tools aren’t necessary. Changing the filter cartridge is also easy. There is an LED light that turns red when it is time for a filter change.

What I love the most is its stylish design. Most of the faucet water filters on the market detract from modern kitchen aesthetics. This filter unit does not. In fact, it can add a touch of futuristic elegance to any kitchen.

Two things can concern people about this faucet water filter. First, it costs more than your average faucet water filter. Second, maintaining it also tends to jack up the price. You see, this product has a filter capacity of only 100 gallons. I have seen products with a 200-gallon or even a 320-gallon capacity.

If you do not mind the cost, the PUR PFM400H is for you. It is one of the most elegant and most effective faucet water filters you can ever install in your kitchen.

What We Like
  • Removes 70 contaminants or more
  • MineralClear filtration technology for better-tasting water
  • Easy to install with no tools
  • Bright LED notification for prompt filter change
  • Elegant and ultra-modern design to improve kitchen aesthetics
What We Don’t Like
  • More expensive than other brands
  • Less economical to maintain than other faucet water filters

6. Brita 35618 Faucet Water System

One of the things that people do not like about Brita is its bland styling. Most of the products of the company have a straightforward design. If you want a stylish and equally-effective water filter for sink faucets from Brita, you should check its 35618 model.

I like the product’s chrome-finished design. It adds a hint of sophistication to any kitchen and is ideal in places that already have plenty of stainless steel or chrome-plated appliances and fixtures.

The product is not only one of the company’s top-looking. It is also one of the most effective in removing water contaminants.

While its filtration performance is not 100% effective, you can bet that 99% of lead and other heavy metals will never go into your drinking or cooking water. It is one of the most efficient faucet-mounted systems that eliminate lead.

Lead is not the only water contaminant this product removes. It can also eliminate sediments, bacteria, and other unwanted particles from your water. Regardless of your water use, you will feel safer because of its quality.

I like the addition of a filter reminder sensor. It makes timely replacement of the filter cartridge easy. Replacing the cartridge also does not require any tool, as you can snap it close, and everything is good.

People will also appreciate the tall design of this filter. It saves space in the kitchen, allowing you to move more efficiently.

Unfortunately, you will not be able to fit this filter into a spray style or a pull-out water faucet. Its filtration capacity is also less than other products I have seen.

Regardless, I would recommend the Brita 35618 to anyone who wants a more elegant way to enjoy filtered water.

What We Like
  • Reduces lead, sediments, bacteria, and other contaminants
  • One-click filter cartridge replacement for ease of maintenance
  • Filter change sensor for more efficient maintenance
  • The design saves space in the kitchen sink

7. Engdenton B07DCMD991 Faucet Filter

The Engdenton B07DCMD991 is an efficient and stylish faucet water filtration system for the modern family. It provides high-quality filtered water on demand. Flip a switch, and you will enjoy filtered water’s benefits.

I appreciate the filter’s robust cartridge design. The material has ultra-adsorptive properties and is a strong magnet against water contaminants. Not only does the system remove chlorine, lead, and rust, it also inhibits bacterial growth. You will feel more confident knowing the glass of water you serve to your family is free of harmful microorganisms and substances.

The advanced carbon filter design also helps improve the water’s overall taste and odor. Enjoying your tea is easy if you get your water straight from this unit. You also will not wait long to fill a gallon, only two minutes.

I like the material used in the filter housing. It is food-grade, allowing you to retain all the advantages of filtered water without any unpleasant taste. You will also like its elegant design. Yes, it is not the most stylish on the market. However, it still looks sexier than other brands because of its stainless-steel polish.

If you worry about frequent filter replacement, do not. The product has one of the highest filtration capacities on the market with 320 gallons. A household with heavy filtered water consumption will love this product.

What I do not like about this faucet water filter is its price. It is more expensive than some products from leading brands. You also cannot connect it to fancy water faucets because it only works with standard types.

The Engdenton B07DCMD991 is not for everyone. But it might be top-tier for households that have heavy filtered water consumption.

What We Like
  • Ultra-adsorptive material for more effective filtration
  • Advanced carbon filter for better taste and odor
  • High water flow design for optimum water consumption
  • High filtration capacity for better economy

8. Culligan FM-25 Faucet Filter

The Culligan FM-25 is a modestly-upgraded version of the FM-15A faucet-mounted water filter. It has the same filtration performance and capacity that any household would want. The difference is in the filtration unit’s design.

The filtration system is more compact than the other model of the company. Its size is perfect for households wanting to optimize their kitchen space. It allows you to work in your kitchen sink without the filter getting in the way.

Like other faucet water filters by the company, this unit effectively removes lead and chlorine. It also removes Giardia cysts and Cryptosporidium spores. The system also improves the clarity of cooking and drinking water. You will never get any odd taste or smell.

If you are doubtful about these claims, it is worth noting that the company had its products tested and certified by IAPMO. The organization tested the filters using the standards set by ANSI. This information should provide enough assurance for doubtful homeowners.

The system not only filters unwanted water particles. It also filters more water than many products. With its 200-gallon filtration capacity, you can minimize cost by reducing the frequency of filter replacement.

The water flow rate is also commendable. You can fill up a half-gallon water jug in one minute, whereas other systems might take longer.

I am not too fond of the plastic adapters included in the package. I wish the company provided more robust adapters to help homeowners. Also, I expected the unit to have a filter change reminder for its price.

Despite these concerns, I believe the Culligan FM-25 is worth buying. Anyone who wants a good combination of filtration performance and capacity should get this product.

What We Like
  • Removes chlorine, lead, cysts, spores, odd taste and smell
  • Improves water clarity
  • High filtration capacity for high-volume users
  • High water flow rate for more efficient water use

Everyone knows how strict Swiss quality control organizations are. It gives you peace of mind, knowing that this faucet water filter delivers safe, fresh, and clean cooking and drinking water.

The testing organization certified the water filter’s ability to remove as much as 99.6% chlorine and lead. It can also remove about half of the arsenic content in water.

While the tests do not account for taste and odor qualities, it is safe to assume that the water you will be cooking or drinking tastes better than usual. It will also not have any unpleasant odor that comes from dissolved chlorine.

What surprised me the most is the product’s filtration capacity. Its compact design suggests a low filtration capacity of only 100 gallons. This is not the case. This device can accommodate 320 gallons, besting many leading brands.

I like its stainless-steel canister, whose sheen can add a sparkle in the kitchen. You will also never have issues with cracks because it is a durable canister that should protect the filter element for many decades.

I wish the company was more accommodating with the pricing of the faucet water filter. It also does not help that the unit only fits standard water faucets.

Even so, the WINGSOL WS-FM001-V5 remains the right choice for any household that wants a high-performance and high-capacity faucet water filter, regardless of price considerations.

What We Like
  • Removes arsenic, lead, chlorine, and unpleasant taste and odor

You will never get the odd smell of chlorine or the unpleasant taste of lead in your water. The system also removes select pesticides and pharmaceutical agents. You will be safer with this faucet water filter in your sink.

Most homeowners love the filter’s ease of installation and replacement. It never requires any tool to pop the filter cartridge out.

You will also never miss replacing the cartridge because the unit already features a filter change sensor. Most products on the market do not have this feature, making maintenance a bit challenging.

While I appreciate its superior filtration performance, I wish the brand would improve on its filtration capacity. Most people find the unit’s 100-gallon capacity to be insufficient for households with heavy water consumption. This water filter is also more expensive than the company’s other products.

However, I still think the PUR FM-3700 is a worthwhile investment. It is the perfect solution for families that do not mind paying more for replacement filters. It looks elegant and does an exceptional job providing you and your family with clean and safe drinking and cooking water.

Washing the dishes? You can switch the device to its unfiltered water setting. If you require a more robust rinsing of items in your kitchen sink, the product’s unfiltered spray will have you all pumped up.

Replacing the filter cartridge is effortless, as no tool is required. You do not even need to record your water consumption. The device already has a built-in sensor and an LED light to keep you abreast of its filter status.

It is worth noting that this faucet water filter system comes with relevant certification from the WQA. Unlike other brands that do not subject their products to rigorous testing, you will feel more confident about this faucet water filter’s performance.

Too bad Brita is not so popular for its design tastes. The product may look boring to some people, but it still does an excellent job of filtering contaminants, even though its 100-gallon capacity is less than ideal.

Outdated Products

BOSNELL Stainless Steel Faucet Water Filter (Outdated)

Most faucet water filters on the market come with disposable filter replacements. The design makes these products costlier in terms of operation. BOSNELL understands what you need. That is why the company designed the Stainless-Steel Faucet Water Filter.

This water filter for sink is unlike any other you may have already seen. It comes with a recyclable filter cartridge. Instead of disposing of the cartridge, you only need to clean it thoroughly. It should then be able to continue filtering unwanted particles from your water.

The filter features Japanese technology. Not only is it efficient in removing unwanted water particles, it also improves the flavor of your beverages. The ACF technology has seven layers that remove even the tiniest particle in water. Rest assured that the water you drink or add to your dish is clean and safe.

You will appreciate the design of this faucet water filter, which can filter up to 320 gallons before you need to replace or recycle the cartridge. In comparison, most systems at this price range can only offer 200 gallons, max.

Water flow is also commendable. In fact, you can fill ten 7-ounce glasses with water in a minute with this product.

I also love its futuristic design. It does not have a mirror finish, but it sure looks elegant in its brushed stainless steel polish.

Unfortunately, the knob feels cheap because of its plastic construction. There is also no filter change notification system, so you’ll have to keep track of your water consumption. Marking the date on a calendar should work fine.

Overall, the BOSNELL Stainless Steel Faucet Water Filter is the right choice for families that want an eco-friendly solution to their water filtration needs. The faucet water filter’s recyclable filter canister is its strongest attribute.

What We Like
  • 7-layer Japan-made filter technology

What Is A Faucet Water Filter/ Who Is This For


A faucet water filter is a small device that bolts into the spout of any water faucet. It is like other types of water filtration systems, only smaller. Its design allows homeowners to install the filter unit easily without requiring professional help.

It is essential to point out that a faucet water filter is not the same as an under-sink water filter. A faucet water filter connects right at the tip of the faucet’s spout, where water comes out. The latter is a part of the water distribution line under the sink and before the faucet.

A faucet water filter is ideal for households that need a kitchen faucet with water filtration capabilities. It works with different water faucets, provided you choose a compatible unit.

The right unit can remove water contaminants, like sediments, heavy metals, and other substances. It can also improve the taste of water.

Many families prefer a faucet water filter because it is easier to install than other water filtration systems.

It also offers them safe drinking water and water for cooking straight from the tap. It is the ideal system for anyone who only requires filtered water from a single faucet.

How Do Faucet Water Filters Work

Faucet water filters work like any other water filtration system. The filter unit consists of at least two layers of filter membranes.

Each membrane has holes that allow the passage of particles smaller than the diameter of the holes. Any particle with a larger diameter than the membrane hole will not be able to pass.

A water filter faucet consists of a filter unit connected to a water faucet through an adapter at the spout’s tip. Water moves along the neck and goes into the filter unit.

The filter unit’s outer core often has a mesh-like filter that traps sediments. Water moves through the inner core of the filter unit while other water contaminants are trapped.

The process results in sediment-free and contaminant-free water, safe enough to drink straight from the faucet.

Many products come with a filter activation mechanism. You can flip a switch or a lever to pass water through the filter. It is perfect for drinking or using water to process and cook food. You can also turn the filter unit off if you do not need filtered water.

What Are The Different Types Of Faucet Water Filters


If you look at a faucet water filter comparison chart, you will notice two distinct types of faucet water filters. Reverse osmosis and carbon filters are the two filtration mechanisms that define a faucet water filter.

Reverse Osmosis

Water safety experts consider a Reverse Osmosis (RO) system as the top-tier water filtration mechanism.

Basic chemistry tells us that osmosis occurs when water molecules move from a dilute solution to a concentrated solution. Reverse osmosis is the opposite — the movement of water molecules from a concentrated solution to a dilute solution. It does this by increasing the osmotic pressure to push water molecules.

Hence, a reverse osmosis faucet water filtration unit pushes water molecules through the filtration membrane but leaves behind other molecules, including ions, heavy metals, other chemicals, and other water contaminants.

A reverse osmosis system removes up to 99% of ALL contaminants, even compounds that other filters cannot remove. The disadvantages of this system are that it is pricier and bulkier. Most households with an RO system have the unit installed under the sink.

Carbon Filter

Many water filtration systems have activated carbon as their principal filtration media. Carbon is an adsorbent material that attracts water contaminants — the chemical attraction bonds the water contaminants to the carbon filter’s unique chemical structure.

The adsorbent properties of activated carbon make it an ideal media for reducing odors. It traps organic and inorganic compounds to provide great-tasting drinking water.

Unfortunately, a carbon filter’s unfiltered water filtration capability is not as efficient as that of an RO system. It may not remove all water contaminants.

High-quality carbon filters can trap cryptosporidium spores, Giardia cysts, and lead. A carbon faucet water filter can reduce between 60 and 80 chemicals.

A carbon faucet water filter is more affordable than a reverse osmosis tap water filtration system.

Advantages And Disadvantages Of Using Faucet Water Filters


One of the most important advantages of using a faucet water filter for kitchen sink is its versatility. You can enjoy filtered and unfiltered water at the flip of a switch.

Filtered water is perfect for drinking. You can also use filtered water for cooking your favorite dishes. You will never have to worry about ruining the taste of your dish ever again.

Another obvious advantage of a faucet water filter is its ease of installation. All you need are basic tools to remove the aerator from your faucet. Replace the aerator with the filter unit adaptor, and you are done. It can save you money from hiring a professional plumber.

Faucet water filters are also less expensive than other filtration systems. You can get a good-quality faucet water filter for less than $30. High-quality units can be more expensive but never breach the $200 mark.


Faucet-mounted filtration systems remove water contaminants to give you safe, great-tasting drinking water. However, do not expect these products to remove all the contaminants from your water.

While faucet mount filters are inexpensive, they may turn out costlier in the long run. The filter cartridge only accommodates about 100 to 400 gallons before it needs a replacement filter.

Households with large water consumption may need tap faucet water filter replacement as often as once every two to three months.

Faucet water filters also reduce the water flow rate. It may take a while for you to fill a glass of water. Most of these water filtration systems work only on select faucet types.

They may also detract from your kitchen’s aesthetics. Some units are bulky and can get in the way of a more efficient kitchen faucet operation. Using the kitchen sink can also be more challenging and time-consuming.

Buying Guide


Choosing the right faucet water filter requires understanding several factors. While these factors are not absolute, they can make choosing the right product easier.

Filter Capacity

One of the most important factors in choosing the right faucet water filter is filtration capacity. Some products can have a filter capacity of 100 gallons. Others may offer you more.

Filter capacity roughly translates to the frequency of filter replacement. The lower the filter capacity, the more frequent the filter cartridge replacement. It can also translate to higher operating costs.

A household that consumes a gallon of filtered water daily can expect to replace their filter cartridge once every 100 days or roughly three months. The same household will need to replace the filter four times in one year.

Filtration Performance

Filtration capacity is insufficient to point you to the right faucet water filter for your family. You may have to consider filter performance, too. Check the different contaminants that the product can filter. You may want a product that can filter chlorine, lead, and other heavy metals as much as possible.

Having a product that removes as much as 99% of common water contaminants will be great. If it can also remove microorganisms, you may want to check what species the filter unit can remove.

It would also be wise to check the filter’s ability to remove odors and unpleasant tastes.

Water Flow Rate

Ideally, you will want a faucet water filter that will not affect your faucet’s flow rate. If you have a faucet water flow rate of 2 gallons per minute, a product with a similar flow rate is advisable. You can get a faucet water filter with a flow rate as close to the original setup.

Faucet Compatibility

It is essential to check the compatibility of the faucet water filter with your existing water faucet. The compatibility of the water filter to your faucet ensures ease of installation and correct fit. You also save money by buying additional adapters.

Filter Change Sensor

It is always great to have a mechanism that tells you exactly when it is time for a filter change. While faucet water filters can have a published service lifespan, keeping track of your filter usage would still be challenging. Having a filter change sensor simplifies monitoring of the filter state.

Swivel Mechanism

Faucet water filters are bulky. It is often helpful to have a 360-degree swivel design to give you enough versatility in the kitchen sink. You can swivel the unit around to gain full access to your sink.

Consumer Reviews

Consumer reports provide you with enough information to make a wise buying decision. Pick a product that has positive reviews. It would also be most suitable to evaluate the negative reviews. It can provide you with a clearer picture of what you are buying.

You may want to avoid limiting yourself to a single tap water filter review. You will not be able to make an accurate product assessment that way.

Frequently Asked Questions (FAQs)

Are faucet water filters worth buying?

Yes, a faucet water filter for well water is worth it if you only want to “filter” the water for your family but not necessarily “purify” it.

Purification and filtration are two different processes. Sadly, many homeowners use the terms interchangeably, thinking a water faucet filter is the same as a water faucet purifier.

Filtration removes solid particles with a diameter larger than the filter membrane holes or “pores” (in microns). Particulates with a small diameter can pass through these holes and still be in the water. Examples are viruses, tiny bacteria, heavy metals, and volatile organic compounds.

Meanwhile, a sink water purifier removes “all” contaminants that pass through the filter membrane. Many systems feature reverse osmosis and UV treatment to “purify” the water.

Hence, a faucet attachment water filter is a good buy if you only want to improve the taste of your water. It should be sufficient to improve the water quality by 20%.

However, a multi-stage whole-house water filtration and purification system is a better investment if you want maximum safety for your family.

Which water filter dispenser removes the most contaminants?

The Pur Advanced faucet water filter removes at least 70 water contaminants, which is ten times greater than the Brita brand of faucet filters.

It helps eliminate mercury, lead, solid particulates, and other contaminants to guarantee better-tasting and safer drinking water. This kitchen sink filter can also lessen the workload of a water softener by reducing minerals.

On the other hand, the Clearly Filtered water filter pitcher removes more than 365 water contaminants, including chromium, lead, arsenic, BPA, and PFAS.

Can bacteria grow in water filters?

The Centers for Disease Control and Prevention says bacteria can grow in a bathroom faucet water filter or any carbon filter, especially if you do not observe proper care and maintenance or follow the manufacturer’s cleaning and replacement recommendations.

A study published in “Environmental Science: Water Research & Technology” revealed that activated carbon block PoU (point-of-use) water filters, such as kitchen faucets with water filter units, can increase biofilm formation.

An increased number of bacteria in the water filter does not automatically translate to harmful drinking water. Healthy individuals can still drink the water as if consuming it from a water purifier for a faucet fixture.

However, people with compromised immune systems might fall ill if they drink water from a faucet water filter with bacterial growth.

What are the most trusted faucet water filter brands?

PUR and Brita are two of the most trusted names in faucet water filters. Many homeowners trust PUR because of its superior water filtration capabilities and elegant styling. On the other hand, Brita offers affordable, readily available, and effective faucet water filters.

Culligan is another trustworthy brand that provides durable, simple, and efficient tap water filtration systems. The company has some of the longest-lasting filters on the market.

WINGSOL and BOSNELL are worth your consideration, too. They offer stainless steel faucet water filters that are perfect for any modern kitchen.

Other trustworthy faucet water filter brands include Engdenton and Waterdrop.

Is PUR or Brita faucet filter better?

PUR comes out on top if you only consider its filtration performance. Make no mistake, Brita water filters are also reliable and efficient in removing impurities from water. However, PUR products remove slightly more contaminants than Brita water filters.

Their product range also comes in more contemporary styles that are perfect for any modern home. PUR water filters are ideal for households that value aesthetics and filtration performance over anything else.

In terms of improving the taste of your drinking water, Brita has the edge. It also has an advantage regarding the availability and affordability of replacement parts. The customer service is also impeccable. You can have your broken and/or defective faucet water filter replaced immediately.

The downside to Brita products is that they do not look ‘sophisticated’ enough. Nevertheless, Brita is the right choice for anyone who wants a simple, effective, and inexpensive solution to filter water.

Are faucet filters better than pitchers?

Convenience is the main advantage of a faucet water filter over water filter pitchers. You have ready access to safe water straight from your faucet. You can fill a glass with ice and have a cold drink immediately.

A water filter pitcher is useful when serving drinking water to diners on the table. However, you must fill the pitcher with water beforehand to allow time for the filtration process.

Faucet water filters do not limit the amount of water you can get, unlike pitchers. Use it for cooking, brushing your teeth, washing the dishes, and many more.

How long do faucet water filters last?

Faucet water filter manufacturers rate their products’ durability in terms of the number of gallons the unit can accommodate before it loses its water filtration capabilities.

Some products can filter up to 100 gallons of water before requiring replacement. Other faucet water filters can accommodate up to 350 gallons or more.

Knowing the faucet water filter’s filtration capacity can give you an idea of how long the product will last.

You will also have to determine your average daily water consumption from the faucet with the water filter. Generally, the higher your water consumption, the shorter the faucet water filter’s service life span.

If your household consumes an average of two gallons per day from a single water faucet, a 100-gallon-rated faucet water filter should last between 45 and 50 days. On the other hand, a 300-gallon faucet water filter can last between 140 and 150 days or roughly five months.

Checking the instructions manual may also help.

Are tap water filters safe?

Yes, tap water filters are safe. American-made faucets and tap water filters must meet EPA regulations before becoming available. Some manufacturers go beyond meeting EPA requirements.

Companies subject their products to rigorous testing by independent laboratories, providing homeowners the peace of mind they need.

The American National Standards Institute (ANSI) and the National Sanitation Foundation (NSF) also provide standards to guide manufacturers in designing and producing safe and efficient tap water filters.

Consumers can rest assured that the water filter will remove as many contaminants from their water as possible.

In general, American water systems are the safest in the world. However, some households remain concerned about the presence of impurities in their drinking water.

They may also be concerned about the taste and smell of their water. Installing a good-quality tap water filter can address these concerns.

How to set up and use?

Setting up a faucet water filter is straightforward. As long as you read the installation instructions of the product you bought, you should be able to get the system up and running in no time.

Faucet water filters require the installation of an adapter in the spout. The spout’s tip has an aerator. You have to remove the aerator first before you can secure the adapter. Also, ensure that the adapter has a rubber gasket to prevent leaks.

Next, remove the filter cartridge from its wrapping and put it into the filter unit. Some products have ‘markers’ that tell you whether the cartridge is in the correct position.

Position the filter unit directly under the faucet adapter. Most products feature a simple plug-in type of installation.

You may hear a ‘click’ as a sign that the filter unit is already secure in the adapter. Other products may require the tightening of a screw.

As for usage, faucet water filters feature a switch in the filter unit. The switch allows you to activate or deactivate the filter.

It would be best to prime the water filter unit before regular use. Activate the filter and allow the faucet to run for five minutes. Run cold water only.

Where to buy faucet water filters?

You can buy a faucet water filter from major e-commerce platforms. Amazon offers the widest selection of products, complete with customer reviews and a dependable distribution system.

Lowes, Home Depot, and Walmart also offer faucet water filters. However, their product offerings may not be as extensive as what Amazon can offer.

The disadvantage of shopping online is that you cannot inspect the product you want to buy before paying for it. You will have to base your decision on the reviews of customers. If this is a deal-breaker, I recommend buying a faucet water filter from a local store.

The unit is effortless to install. Replacing the filter cartridge is also never an issue. It is a cost-effective solution to enjoying fresh, safe, and clean water. Buy one today!
