Best Countertop Water Filter Reviews

1. iSpring CKC1 Countertop Water Filtration

With its exceptional contaminant-removal capabilities at an attractive price, the iSpring CKC1 might be the best countertop water filter system anyone can buy. This device fits nicely in any kitchen countertop or anywhere where there is a faucet.

This countertop water filter has a straightforward design that should sit well on any surface. Its 5×5-inch footprint will never create clutter on your countertop or table, making this water filtration system the ideal solution for space-deprived homeowners.

I like the water filter’s chlorine and sediment removal capabilities. Reducing chlorine levels to only five percent translates to better-tasting water. Cooking meals and preparing refreshing drinks is a joy with this unit in the kitchen. You can say goodbye to silt, sand, and other particles that may be present in your cooking or drinking water.

It pays to know that this alternative to water filter pitchers underwent rigorous third-party testing to guarantee its filtration performance and received numerous positive consumer reports. The good news is that an independent laboratory tested this countertop water filter according to ANSI/NSF standards.

While the filter lasts only six months, it is still longer than other brands. It is easy to install, requiring only the diverter adapter’s attachment to the kitchen faucet. You can have this baby working for your family’s drinking and cooking needs in no time.

If you need to address TDS, you will need a different product. It is also worth pointing out that this unit comes with a plastic diverter valve adapter. Some people may prefer metal over plastic.

The iSpring CKC1 offers exceptional value for money because of its compact and space-saving design and reliable water filtration performance. You will never regret spending your dollars on this device to ensure safe drinking and cooking water for your family.

2. Aquasana AQ-4000W Countertop Water Filter

Most homeowners feel more confident if the countertop water filter they buy has a valid NSF International certification. It gives them peace of mind, knowing their purchase underwent rigorous testing and evaluation by a reputable organization. One such product you can feel more confident about is the Aquasana AQ-4000W.

This counter top water filtration product has several NSF certifications, including NSF 42, NSF 53, NSF 401, and 473. These certifications guarantee wide coverage of 76 common and emerging tap water contaminants. You will never have to worry about chlorine, lead, mercury, pesticides, herbicides, pharmaceutical agents, and other nasty substances in your tap water.

You will love the Claryum filter as I do. This model features four different filtration technologies, including activated carbon, catalytic carbon, sub-micron mechanical filtration, and ion-exchange filtration mechanism.

The remarkable combination of different filtration mechanisms accounts for this unit’s astonishing water contaminant removal capabilities. It is the kind of technology that makes you feel confident every time you get water from its sleek spout. The meals you cook and the beverages you prepare are at their absolute best.

One minor issue you might want to consider is the filter’s width. At seven inches, it is two inches wider than iSpring CKC1 filters. It is still compact with a height of only four inches.

The Aquasana AQ-4000W is one of the most exciting countertop water filters you can ever buy. It may be more expensive than other brands. However, its unquestionable tap water filtration performance gives you peace of mind no money can buy.

3. iFilters Countertop Ultra Water Filter

One of the drawbacks of countertop water filters is their higher running costs than other filtration systems. You tend to replace the filter cartridge more frequently, often every three to six months. With the iFilters counter top water filtration system, you may only have to replace the tap water filter after a year.

Most countertop water filters can only accommodate 300 to 500 gallons of water, translating to about four to six months’ use. This model delivers 750 gallons of water, good for about a dozen months. It is a more economical water filtration solution, especially among dormers, small apartment dwellers, and RV owners.

The 0.5-micron filter is also more efficient than conventional 1-micron units. Chlorine, mercury, lead, organic chemicals, asbestos, some bacteria, and cysts will never pass through the membrane. You will feel safer about the tap water you give to your family to drink or the water you use to cook meals or prepare drinks.

This product’s 97% chlorine removal performance is better than other brands that can only remove 95% chlorine. At least, the tap water you drink or use in cooking will taste great.

While this countertop water filter has an excellent filter lifespan, you can only use the brand’s replacement filters. It is also worth considering its certification status. The filtration performance numbers are impressive, except that they are not NSF-certified. The company only uses NSF-approved materials.

The iFilters Countertop Ultra Drinking Water Filter is the right choice for families who want a more economical solution to accessible drinking and cooking water. Its long-lasting water filter lifespan also enhances its practicality without reneging on its water contaminant removal performance.

What We Like
  • Recommended for RVs, dorms, and studio apartments
  • 0.5-micron filter size for more efficient contaminant removal
  • Capable of removing up to 97% chlorine and other water contaminants
  • 750-gallon water capacity for better economy
  • Exceptional value for money
What We Don’t Like
  • Not compatible with non-iFilters replacement filters
  • Only NSF/ANSI approved materials

4. APEC Water Systems RO-CTOP Water Filter

Reverse osmosis filters are the best when it comes to addressing total dissolved solids. The APEC Water Systems RO-CTOP offers both reverse osmosis and carbon filter systems in a compact and portable design. This model provides you with the most effective water contaminant removal money can buy.

This countertop drinking water filter has four stages of filtration that make it easy to remove almost all water contaminants. There is a 5-micron filter for removing large sediments and particles. This model also has an ACF that removes unpleasant water tastes and odors as well as VOCs and other chemicals.

I love this countertop water filter’s FILMTEC TFC reverse osmosis technology. This system enables the unit to remove up to 99% of known tap water contaminants, including lead, arsenic, chromium, radium, fluoride, and more. There are also negligible amounts of dissolved solids after filtration, making for fantastic drinking water.

I appreciate the unit’s design because it does not impede water flow. You can enjoy safe and clean drinking water of up to 90 gallons per day. It is also easy to install and compact enough to be brought anywhere.

I only wish the company had a better design for this countertop drinking water filter because it does not look good on the countertop. It looks like you have a chemistry experiment setup instead of a fully functional RO system.

The combination of an activated carbon and a reverse osmosis system also makes this product about eight times more expensive than conventional countertop water filters.

The APEC Water Systems RO-CTOP is worth every penny you spend because of its dual filtration technologies. You get the best of activated carbon and reverse osmosis systems in a compact and easy-to-install design.

What We Like
  • RO and carbon technologies for more efficient tap water filtration
  • Four-stage filter design for more effective contaminant removal
  • High-flow design for optimal water use
  • Ease of installation
  • Portable design for easy transfer
What We Don’t Like
  • Not the most aesthetically-pleasing countertop water filter design
  • Very expensive compared to conventional filters

5. Berkey BK4X2 Countertop Water Filter

Homeowners worldwide trust Berkey to deliver the most amazing water filters on the planet. The brand’s BK4X2 is one of the best countertop water filters you will ever see. It has a robust design that protects its filtration mechanism.

At the core of this countertop drinking water filter is a pair of purification elements, capable of removing microorganisms and at least 100 contaminants from your drinking and cooking water. Most systems I know can only eliminate about 60 or 70 water contaminants. They can also only remove a few bacteria, parasites, and cysts.

The BK4X2 Berkey water filter looks like a tank on your countertop. Once set up, you can enjoy up to seven gallons of purified water per hour. Its water filters are also durable, capable of filtering 3,000 gallons before replacement. Since the unit has two filters, you get a 6,000-gallon filtration capacity. There is also a fluoride post-filter that accommodates 1,000 gallons.

These stats make this countertop water filter model ideal for households of four to sixteen people.

I have two peeves about this countertop water filtration system. First, it is bulkier than other so-called portable water filters I know. Its 8.5-inch diameter base may not fit on small countertops. Its 19.25-inch tall housing can also be a problem if you have a low-hang cabinet over the counter.

The second is its price. At about half a grand, this countertop water filter is beyond the ordinary household’s reach. Given its remarkable water purification capabilities, its price is understandable.

The Berkey BK4X2 may be an expensive countertop water filtration system option. However, it is one of the most effective and efficient if you are a fan of high-quality and safe purified drinking and cooking water for your family.

What We Like
  • Has a robust design
  • Two countertop water filtration system elements for efficient contaminant removal
  • Efficient removal of at least 100 different water contaminants
  • Recommended for medium to large households
  • High-capacity purification and fluoride filters for better economy
What We Don’t Like
  • Not a real space-saver
  • Very expensive for the ordinary household

6. APEX EXPRT MR-2050 Countertop Water Filter

If you are the type of person who believes in the benefits of alkaline water, you should get the APEX EXPRT MR-2050. This countertop filtered water dispenser not only removes common water contaminants. It also alkalinizes your drinking and cooking water.

I love this countertop water filter’s NSF/ANSI-compliant materials because they make you feel more confident about its 99% water contaminant removal performance. This filter also makes it impossible for microorganisms to grow and thrive, further improving water quality. No longer will you have to worry about your water affecting your health.

I like this product’s five-stage filtration system because it offers enough semi-permeable membranes of varying hole sizes to remove common water contaminants. Radon, benzene, chloramine, and other heavy metals will never pass through these filtration layers. You also get rid of that nasty chlorine taste and smell for a more pleasant drinking experience.

I do have a gripe about its design. I wish the company encased the two filter towers into more appealing housings. It feels like you have a water refilling station in your home with this setup. It also tends to occupy more space than other products. Installation is a breeze, nevertheless.

Despite not having an elegant design, one can never argue with the APEX XPRT MR-2050’s filtration performance. With its remarkable alkalizing and microbial growth prevention capabilities, this countertop water filtration system is worth having in your home.

What We Like
  • Five-stage filtration system for more efficient contaminant removal
  • Water alkalinization and prevention of microorganism buildup
  • Up to 99% reduction in common water contaminants for safe drinking water
  • NSF/ANSI standard materials for peace of mind
  • Installing is a breeze
What We Don’t Like
  • Not as space-saving as other countertop water filters
  • Has an unappealing design

7. Brondell H630 H2O+ Cypress

I cannot take my eyes off the Brondell H630 H2O+ Cypress. I am sure you won’t be able to, either. It has the most striking designs among countertop water filters today. If you do not know about it, you will not even think that it is a countertop water filtration system.

The product’s ultra-modern design makes it one of the best table top water filter systems you can buy. Its small footprint should sit well on any countertop, adding another aesthetic element to your kitchen.

While this water filter is beautiful, it does not fail in its contaminant removal promise. This model has appropriate certifications from the Water Quality Association, validating the product’s contaminant removal claims. The organization certifies the water filter’s conformity to NSF standards 372, 53, and 42, giving you the confidence you need every time you drink water from its faucet.

I love its NanoTrap technology that forms the system’s second filter stage. This system features natural cellulose fibers and nano alumina to improve water clarity and reduce as many water contaminants as possible. The first filter takes care of large particles, while the third element finishes the purification process.

My only concern is the filter’s larger-than-usual holes. Other best countertop brands feature 0.5-micron carbon block filters. This product has a 2-micron pore size. Given its filter characteristics, I find its price a little bit prohibitive. Perhaps, it is its stylish design that you are paying a premium for.

With the looks of a futuristic water filtration system, the Brondell H630 is the right choice for stylish homes. Its sleek design can complement any modern kitchen décor while its filtration performance is good enough to replace a conventional under-the-sink water filtration system.

What We Like
  • Three-stage filtration technology for more effective particle removal
  • NanoTrap filter technology for more efficient contaminant removal
  • WQA certification for following NSF 42, NSF 53, and NSF 372 standards
  • Stylish, compact, and ultra-modern design for kitchen aesthetics improvement
What We Don’t Like
  • A bigger filter hole than other countertop water filter brands
  • A bit expensive

8. Lake Industries Countertop Water Purifier

The Lake Industries Stainless Steel Countertop Water Purifier is an excellent choice for homes that want a longer-lasting filter cartridge. It has a straightforward design that guarantees worry-free installation within minutes.

One of the biggest draws of this countertop filter is its NSF certification. For most families, having the NSF seal on a product makes them feel confident about the countertop water filter’s performance. You will know that the product can remove water contaminants at its claimed rating because of the NSF certification.

As far as water contaminant removal goes, this countertop filter can remove up to 97% of chlorine. You will also notice a substantial improvement in drinking water taste and odor characteristics. Preparing your favorite summertime drinks should always be more enjoyable with the water coming from this model.

I like its design. It may look simple and bland, but it can deliver its promise of removing VOCs, radon, and Class I particulates. Its remarkable construction is also worthy of note, especially the use of stainless steel.

This product’s best asset is its 1,000-gallon high-capacity carbon block filter. Most products I know can only accommodate 400 to 500 gallons of water before requiring filter cartridge replacement.

If there is one thing I wish the company will improve on, it will be the filter’s pore size. At only 10 microns, small particles can pass easily through the membrane. You will also not be able to reduce total dissolved solids. The company did not design this countertop filter for such a purpose.

Despite its large filter pore size, I still recommend the Lake Industries Countertop Water Purifier. This countertop filter efficiently removes common water contaminants and is effortless to install on your own. It is quite affordable, too.

What We Like
  • 97% chlorine removal capability
  • Efficient removal of Class I particulates, radon, VOCs, and bad tastes and odor
  • Stainless steel construction
  • 1000-gallon water filter capacity for better economy
  • NSF certification for enhanced water filtration confidence
  • Easy installation and affordable price
What We Don’t Like
  • 10-micron pore size
  • Not ideal for TDS reduction

9. RKIN AlcaPure Countertop Water Filter

Any family that wants a reliable countertop water purifier should consider the RKIN AlcaPure. This countertop water filter combines the water contaminant removal performance of a reverse osmosis system with the odor and taste improvement capabilities of activated carbon. It provides you with safer and more refreshing drinking water.

This device comes with a four-stage filtration technology that starts with a sediment filter. The second stage features activated carbon that traps whatever particles the first filter did not remove.

The water then moves to the system’s reverse osmosis membrane and postfilter to remove up to 99 percent of known water contaminants. You can rest assured that chlorine, lead, mercury, arsenic, and other heavy metals will never go into your glass of water. It is easy to reduce TDS with this countertop filter.

The problem with RO systems is that they trap all solutes, including minerals necessary for health. The inclusion of an AlcaPure technology addresses this concern by returning calcium and magnesium into the filtered water to bring its pH to a more alkaline level.

My only comment is that this product looks more like an ordinary tabletop water dispenser or a coffee machine. It can be bulky and a real challenge to people with limited countertop space. While the device does not require any installation, refilling its front-loading water reservoir can be a hassle for some people.

The RKIN AlcaPure’s drawbacks are minor hiccups compared to what it can offer to your family. It requires no installation and has phenomenal water contaminant removal capabilities. You will never ask for more.

What We Like
  • Four-stage filtration that includes AC and RO systems
  • AlcaPure technology for alkalizing water
  • Capable of reducing TDS levels to negligible levels
  • Zero-tool, zero-installation requirement
What We Don’t Like
  • Not the most compact countertop water filter on the market
  • Manual filling of water compartment can be tedious

10. AmazonBasics AMZB-G30CW Filtration

AmazonBasics continues to blitz the market with its reliable and affordable products. Take the AMZB-G30CQ Filtration System, for instance. The over the counter water filter system has enough features to blast other brands on the market.

I admire this water filter’s simplistic yet functional design. Most products have the spout connected to the water filter’s base. On the other hand, this best countertop filter has its spout coming through the top like a soap dispenser. The unique design minimizes its footprint, making it ideal for people with cramped countertops.

I also like its shiny black finish. You will never think of the unit as a water dispenser. It should add a nice touch to your kitchen.

What blew me away is the water filter’s 30,000-gallon capacity. Most countertop water filters I know have less than a 5,000-gallon capacity. This five-stage water filter will last you several years with average water consumption, translating to better economy.

While AmazonBasics limited its AMZB-G30CW’s filtration performance to chlorine, particulates, odor, and taste only, it remains a good choice because of its long-lasting life. It can be a great choice for anyone who only wants to improve the drinking characteristics of his water.

If you need filters that remove microorganisms and other harmful compounds, this is not for you. The company designed this countertop water filter to remove only particulates, chlorine and its associated taste and odor.

While the unit has a straightforward installation, some people find the adapter to be less-than-ideal. Leaks developed because of a mismatch between the spout and adapter threads. Most customers had to look for more suitable hardware to address the leaky issue.

What We Like
  • Five-stage water filter system for more efficient removal of common contaminants
  • Long-lasting filter cartridge design for improved economy
  • Small footprint and compact design for optimum portability
  • Simple yet elegant design for complementing kitchen countertop aesthetics
  • Not hard to install
What We Don’t Like
  • Only for removing chlorine and particulates
  • Some issues with leaks

11. Waterdrop WD-CTF-01 Countertop Filtration

One of the most amazing countertop water filters you can buy is the Waterdrop WD-CTF-01. This device has a modern design with a classic brushed stainless steel finish that sparkles in your kitchen. It will never detract from your countertop’s contemporary aesthetics.

I love this water filter’s five-stage filtration mechanism, including an activated carbon block, a kinetic degradation fluxion, a sediment filter, a mineralization filtration media, and a taste-enhancing polypropylene membrane.

The combination of multiple filtration media increases the unit’s contaminant removal capabilities. While there are no NSF/ANSI certifications to prove it, you will have a good idea of its filtration performance once you drink water from it.

Gone is the unpleasant odor and taste of chlorine. You will also never fret about heavy metals, sediments, colloids, arsenic, fluoride, hydrogen sulfide, and other chemicals. The on counter water filter eliminates these substances before you even put your glass under its sleek spout.

I like the inclusion of a mineralization filtration media because it returns magnesium, calcium, and other beneficial minerals to your drinking water.

You will never worry about replacing the cartridge often. Unlike other products that have a low filter capacity, this product can accommodate up to 8,000 gallons. You might only replace the cartridge after a year’s use.

While this countertop water filter is excellent in removing up to 99% of chlorine, it cannot reduce total dissolved solids. If this is what you are after, you may want to try the company’s RO system.

The Waterdrop WD-CTF-01 is the right choice for modern families that need a more modern-looking, minimalist, and effective countertop water filter. It may not have NSF certification, but it does not matter because of the fantastic results it brings to the average family.

What We Like
  • Effective in removing chlorine, taste, odor, and other common water contaminants
  • Five-stage filtration system for effective removal of contaminants
  • Mineralization filtration media for alkalizing water
  • High-capacity filter cartridge for ease of maintenance and improved economy
  • Sleek and modern design to complement kitchen aesthetics
What We Don’t Like
  • Not ideal for reducing TDS
  • Not NSF certified

12. ESOW Countertop Water Filter

The ESOW countertop water filtration system is an elegant-looking device that delivers safe and clean drinking water for everyone in the house. It has a slim filter housing and a solid base that will never create an eyesore in your kitchen countertop.

While this unit only has three filtration stages, it can remove up to 99% of lead, chlorine, and pharmaceutical byproducts. The system also reduces mercury levels by up to 96% and pesticides by up to 92%. We have yet to include its odor and taste-enhancing capabilities, making this water filter one of the best in the market today.

I admire the company’s technology for reducing the filter pore size to about 0.1 microns. Most countertop water filters have a minimum pore size of 0.5 microns. If these systems can already remove bacteria, cysts, and parasites, it would be easy to imagine how this water filter can remove more germs.

I also like its mineral retention capabilities. The majority of filters remove even beneficial minerals, such as calcium and magnesium. This system retains those minerals that your body needs. Not only are you getting rid of the nasty stuff in your drinking water. You also ensure the beneficial elements are in every glass of water you drink.

Unfortunately, its small pore size is not enough to reduce total dissolved solids. You might also want to check your faucet first to ensure compatibility. This countertop water filter only works with standard faucets and not with specialty types.

The ESOW Countertop Water Filter’s design makes it one of the best-looking filters money can buy. It also does an excellent job removing many water contaminants because of its small pore size.

What We Like
  • Three-stage filtration mechanism for efficient removal of water contaminants
  • Ideal for lead, chlorine, mercury, pharmaceuticals, and pesticide removal
  • 0.1-micron pore size can remove more microorganisms than other brands
  • Improves water taste and odor characteristics
  • Retains good minerals
  • Ultra-sleek and minimalist filter housing for kitchen aesthetics improvement
What We Don’t Like
  • Not recommended for people who want to reduce TDS levels
  • Compatible only with standard faucets

What Is A Countertop Water Filter/ Who This Is For

best-countertop-water-filter-system

A countertop water filter is one of the simplest and effective water filtration systems in the market. It has a compact design and an effortless installation process that are ideal for different applications. You can place this gadget on your countertop near the sink or on your table.

Depending on the product’s filter design, countertop filters can remove chlorine, unpleasant taste and odor, and other chemicals. Some filters can also reduce total dissolved solids, while others inactivate harmful microorganisms.

Because of its ease of installation and compact design, a countertop water filter is perfect for anyone who wants a clean water supply. You can drink straight from the filter device’s faucet without worrying about contaminants in your water. Cooking delicious meals or preparing refreshing drinks is also easier with this device on your countertop.

Installation is never a problem because the device does not need major changes to your plumbing.

How Do Countertop Water Filters Work

Countertop water purification systems work like any other water filtration system. Unfiltered water passes through a contaminant removal mechanism or membrane to produce filtered water in the other end.

Countertop filters have a few basic parts, including a diverter valve adapter, connecting tube, and filter unit. Inside the device is a filtration mechanism or membrane that removes water contaminants or inactivates harmful substances, depending on the filter design.

The water filter system connects to your faucet’s spout, replacing the aerator if your faucet has one. When you open your kitchen faucet and turn the diverter valve dial in the filter’s direction, you move water to the filter unit.

Water goes through the device’s filtration membrane to remove contaminants, odor, and unpleasant taste. Filtered water goes out of the device’s built-in spout, ready for drinking or cooking.

If you require unfiltered water for other purposes, you can turn the diverter valve lever in the kitchen faucet’s direction. Water flows straight through the faucet and out the spout instead of getting diverted to the water filter unit.

What Are The Different Types Of Countertop Water Filter

counter-top-water-filtration

The National Sanitation Foundation classifies countertop water filters as a point-of-use system you can install where you need ready access to water. The following are the most common types of countertop water filters.

Carbon Filters

The most common type, carbon media are ideal for improving water odor and taste because of the adsorbent characteristics of carbon. These filters act like a sponge that attracts and traps odor and taste molecules, making for more refreshing water to drink.

Carbon filtration media are also great for chlorine and chloramine removal, as well as the reduction of VOCs, herbicides, pesticides, and other harmful chemicals. These filters have a large pore size of about 1 micron in diameter. Smaller particles can pass through these pores easily, making carbon filters ineffective against microscopic substances.

Reverse Osmosis Systems

These products work by pushing only water molecules through a semipermeable membrane, leaving all other particles behind.

Normal osmosis moves water from an area with a high water molecule concentration to an area with a low water molecule concentration. Reverse osmosis moves water in the opposite direction, making the already diluted water compartment even more dilute. Other particles collect on the other side of the membrane.

Reverse osmosis filters are the most efficient water filtration system because they remove almost everything in water, except H2O molecules. That is why many people consider reverse osmosis as a water purification system or a countertop water distiller.

Its remarkable contaminant-removal capabilities make the RO water filter ideal for those who want to reduce total dissolved solids, suspended compounds, and even bacterial species. Large-scale industries use this water filter type in potable water production.

Ceramic Filters

Reverse osmosis is impressive as a countertop water distiller alternative. Unfortunately, these countertop models are quite expensive. A good alternative is a ceramic water filter that can remove bacteria and cysts.

Ceramic pores have a diameter of 0.5 to 0.7 microns, trapping bacteria and other large microorganisms. Most ceramic products have silver impregnation, giving the device bacteriostatic properties. Adding silver also improves control of microbial growth in the filter’s exterior.

The main advantage of ceramic filters is that they are reusable. You can remove them from their housing, clean them thoroughly, and replace them. They offer longevity that no other water filter type can.

Ultra Filters and Nano Filters

Ultrafiltration and nanofiltration use smaller pore filters than ceramic systems. Whatever microorganism and particles can escape through the latter do not stand a chance of passing through the super-fine mesh of ultra and nano filters.

UV Filters

A countertop UV water purifier is perfect for families who want germ-free drinking and cooking water. The device features an ultraviolet element that delivers 254-nm wavelength radiation that disrupts microbial DNA. The genetic disruption prevents bacterial, viral, and fungal reproduction.

This system effectively inactivates Cryptosporidium, Giardia, Salmonella, E. coli, Hepatitis B, Mycobacterium tuberculosis, and more. Unfortunately, UV filters do not remove unpleasant taste and odor.

Advantages And Disadvantages Of Using A Countertop Water Filter

Countertop water filters offer a few distinct advantages, including affordability and ease of installation. If you choose well, you can complement your kitchen’s aesthetics.

Effortless Installation

 You only need to connect the countertop water filter’s tube to a diverter adapter in your kitchen faucet spout. It cannot get any more straightforward than that.

Low Upfront Costs

 Countertop water filters can be as affordable as $50 or as expensive as $1,000-plus. The good news is that you will always have options to fit in your budget, even if you choose a UK product.

Hassle-free Operation

 Operating a countertop water filter is similar to using your faucet. Turn off the diverter valve to move water through the kitchen faucet if you want unfiltered water. Pull the valve to divert water to the filtration unit and enjoy safe, filtered water.

Space-saver

 Perfect for families with small spaces, countertop water filters have a small footprint.

Unfortunately, there are some drawbacks to using a countertop water filter.

Pricier than Faucet Filters and Water Filter Pitchers

While affordable, countertop water filters are a little more expensive than faucet water filters or even water filter pitchers.

Limited Filtration Capacity

 Countertop water filters can only do so much in removing water contaminants. On average, countertop water filters may last only about three to six months. You also cannot expand the system to include other water filter types.

High Running Costs

The filter’s limited filtration capacity translates to more frequent filter cartridge replacement. It can be an expensive system in the long run.

Buying Guide

countertop-water-filtration-system

Most homeowners find choosing the best countertop water filter confusing, if not challenging. Many of them find the ocean of options bewildering since almost every product looks like the others. While you can find recommendations from online communities like Reddit or read countertop water filter reviews, you may want to check this countertop water filter buying guide we prepared for you.

Determine What You Do Not Want from Your Water

Many homeowners do not like the taste and odor of chlorine every time they drink. Others are wary of sediments, rust, colloids, pesticides, pharmaceutical byproducts, and heavy metals like argon, mercury, lead, arsenic, and more.

There are also households that worry about bacteria, parasites, viruses, cysts, and other germs in their drinking or cooking water. You may also be one of those people who want the complete absence of dissolved solids. Some people may want alkaline drinking water to enjoy an immune boost and strong bones.

You should know that countertop water filters use different filtration media designed for a specific purpose. In general, the more filtration media types a water filtration system contains, the more effective it is in producing pure drinking water.

Check How Much Water You Drink or Use for Cooking Everyday

Running your tap water through a filtration membrane can reduce its flow rate. It is especially noticeable in old water filters because of the clogging of the pores by trapped water contaminants.

A newly-installed countertop water filter can still have a substantially lower flow rate than your faucet. It is best to consider how many gallons of water you get from the faucet everyday. You can compare this number to the figure on the water filter.

On average, countertop water filters can provide three to four gallons of water per hour or roughly 10 cups per minute.

Assess the Space Where You Intend to Place the Countertop Water Filter

Some countertop water filters have a narrow base that will take minimal countertop space. Some units have a circular footprint for better space savings.

Make sure to check the countertop area where you intend to position the water filter. It is often wise to take measurements and compare them with the countertop water filter’s physical dimensions.

Determine Your Budget, Including Operating Budget

You can have a reliable countertop water filter for less than $50. Others may require you to shell out up to $1,000.

A more important cost consideration is the filter capacity. The larger the filter capacity, the less frequent the filter cartridge replacement. You will lessen your cost of buying replacement filters if the product you purchase has a long-lasting filter cartridge.

Check If You Have Basic Plumbing Tools

Countertop water filters require minimal installation. However, you will still need tools to remove the faucet aerator and secure the diverter adapter. Most products already come with basic tools. Others do not.

In general, reverse osmosis systems do a better job at contaminant removal because of their unique mechanism. Conventional countertop filters move particles across a semipermeable membrane. Any particle larger than the membrane holes cannot pass.

Reverse osmosis countertop filters focus more on passing water molecules, leaving behind any particle not resembling water. In theory, this characteristic makes the reverse osmosis water filter more capable of removing more contaminants than traditional carbon block filters.

How to install countertop water filter system?

Countertop water filters are straightforward to install, requiring only the most basic plumbing tools. The basic design of such a product requires a connection to the kitchen faucet. These products come with a diverter adapter that installs into the faucet spout.

Always check your faucet to see if it comes with an aerator. Remove the faucet aerator if your unit has one. Connect the filter faucet adapter to the spout, ensuring security to avoid leaks. Connect the countertop water filter tube to the adapter.

It is always best to test the installation for leaks and to prime the filter unit. To do this, turn the lever in the direction of the pipe and open the faucet. Allow water to flow through the faucet for at least 15 minutes.

Turn the lever in the direction of the kitchen faucet’s spout without turning off the faucet. Water should flow straight into your sink.

If you’re on the road and want something that requires no electricity or connection to a water supply, try a countertop gravity water filter.

How to care and clean?

Caring for your countertop water filter is straightforward because of its simple design. Many products are similar to faucet filters with fewer complicated components than whole-house or under-the-sink water filtration systems.

It would be best to read the manufacturer’s instructions on how to maintain the unit’s integrity. It is often best to clean the filter housing as frequently as possible, using a clean cloth.

Filter cartridges have a definite lifespan, depending on the material and design. For example, carbon block filters typically last about four to six months.
