That strange hint of swimming pool taste in your tap water should be a warning. The chlorine mixed with your water coming into your home is there to kill bacteria and protozoa. It’s not good for you or your family and no one knows the long-term effects of drinking it.

Best Countertop Water Filter

Combine the chlorine with heavy metals, magnesium, calcium, and up to 50 other chemicals commonly found in city water and you have a problem waiting to happen.

Complete home osmosis systems are expensive and require professional installation. You can improve your water, and by default, your health with a countertop filter. Selecting the best countertop water filter is what we’re about to tell you about.

Countertop water filters are a convenient way to create clean, chemical-free water to drink or cook with.

There is no plumbing to hook up, just pour in the dirty water and pour out the clean.

Types of Countertop Filtration System 

There are two main types of countertop filtration systems. Their systems that sit upon your countertop that is connected to a water line, these are very popular.

There are also systems that you must fill with tap water into the top holding tank, and water will trickle down through filters into a clean water reservoir.

1. Water Line and Faucet Connected Countertop Water Filters

The type of countertop filters that connect to a water line has many benefits, which is why they are so popular. They are easy to install and require virtually no plumbing experience. They connect to your already existing sink’s faucet.

These are a preferred style of countertop filters to may people because there is no limit to the amount of water you have access to. It draws water from your main sinks water supply, making water always available.

2. Gravity Fed Countertop Water Filters

These systems do not have a water line that must be connected to a local water supply. Rather, they have a holding tank that you can fill with water, and as the water flows down (Gravity!) it goes through a filtering process and into a holding tank.

These are usually larger than water line connected systems, have limited water amounts, but they are mobile. You can bring your clean water supply with you wherever you go. These are not nearly as common as waterline and faucet connected countertop systems.

3. Water Distillers and Filter Combinations

For people that rely on distilled water, you can purchase a water distiller that combines with a few filtering features. These are not the most popular choice for people who do not need distilled water, but they are a great option for those who do.

By combining a boiling process, steam filter, and collection tank, water distillers can provide you with clean and distilled water, right from home. They usually take longer but will save you money in the long run on distilled water bottles.

How Do Countertop Water Filters Work?

Countertop water filters are so popular because they work so simply. When it comes to water line connected filters, the way they work is very simple.

The filters come with a water line and faucet adapter so that you can connect your current faucet to the water filter. Water will flow from your existing faucet and into the countertop filtration system  where it will be purified, and harmful contaminants will be filtered out. Once the water is done being filtered, it is ready to be used.

Countertop Water Filtration system

Most countertop water filters have a dedicated faucet that is attached to the filter. This is entirely separate from your existing faucet and will only produce purified water. One nice feature that many countertop water filters possess is a water diverter valve.

This is the thing that connects your old faucet with the new filter. This diverter valve will allow you to choose where the water will flow, either out of your original existing faucet (unfiltered) or into the new countertop water filter.

Gravity-fed countertop systems are even simpler than the standard countertop filters. They usually contain two separate containers for water. You load the top of the system with water, and the water will flow downward into the filtration stages.

When the water is done being filtered, there is another water collection area, usually called a reservoir. Here is where clean water collects. You then use a spigot to release the clean water into your water bottle or mug. They are popular systems because there is no plumbing needed, and they have no need for a water line.

Should you Install a Countertop Water Filter?

Countertop water filters are a great option for many homeowners and renters. The convenience, affordability, and overall effectiveness against unpurified water make them a wonderful solution for clean drinking water.

If you are someone who (understandably) tends to shy away from plumbing work of any type, then countertop filters are a good option for you. There is no manipulation of your current plumbing, and there is usually no need to even get the toolbox when it comes to installation. The simplicity of their design cannot be overstated.

The biggest reason why someone may want to choose a countertop water filter is because of the cost. A whole-home system can cost thousands of dollars and usually require some know-how when it comes to installation. If your goal is to find a good solution for clean drinking water, then a countertop filtration system can provide that, for a fraction of the cost.

What Common Contaminants Does a Countertop Water Filter Remove?

Standard inline water filters attached to the sink tap are just fiber filters that catch pollutants, chemicals, debris, and small amounts of bacteria by trapping them in activated carbon fibers.  They don’t stop all bacteria, only a reverse osmosis filter can do that.

A reverse osmosis style countertop water filter creates distilled water as its final product. The chemicals, including, chlorine, lead, magnesium, and even trace amounts of pharmaceuticals are all removed during the reverse osmosis filtration process.

Mechanical filters can remove most of the pollutants from your water, but it takes an osmosis system to remove them all. A full home osmosis system can cost between $10,000 and $20,000 to install. A countertop model is much more affordable, and provides the same product, only on a smaller scale since it process just limited amounts for cooking and drinking.

The Advantages of Countertop Water Filter

  • Better Tasting Water
  • Healthier Water Sources
  • Easier Installation
  • Saves Money
  • Easy to Maintain

Better Tasting Water

Water without chemicals tastes better. Chlorine with its bitter metallic flavor is the top source of poor tasting water. A countertop water filter removes that taste.

Healthier Water Sources

Water devoid of lead, magnesium, calcium, and pharmaceuticals is just better for you. You won’t ingest these hidden chemicals if your filter traps them first.

Easier Installation

Reviews of the best countertop water filter on the market all have similarities.  Put the filter on the countertop, plug it in, fill it with water, push the button, wait a few minutes and you have pristine natural water. Installation is easy because there is none.

Saves Money

Buying bottled water can be expensive, arduous and when you run out, it’s time to haul those heavy jugs back to the store, or to call your delivery service. A countertop filter provides water on demand, no waiting, no lift, just clean water.

Easy to Maintain

Maintenance of a countertop water filter is simple. Pour the tap water in, let the machine work. Pour the clean water out, and pour the waste product down the drain.

Best Countertop Water Filtration System Reviews

1. AquaTru – Reverse Osmosism Countertop Water Filtration system

It’s time to throw out those plastic water bottles once you taste the water from the AquaTru Reverse Osmosis system.  The AquaTru is one of the best countertop reverse osmosis water filter systems you can buy.

AquaTru - Reverse Osmosism Countertop

The device handles three quarts of water at a time, takes up very little countertop space with a small footprint of 14x12x14 inches, and best of all, the water it produces tastes great.

The AquaTru is designed to removed lead, arsenic, carcinogens, chromium, and drug residue, in addition to the standard threats of calcium, chlorine, and bacteria.

This cost-effective system requires no plumbing. Just fill the three-quarter reservoir and let the machine do its magic.

The system is designed to last six months to two years without changing the filter. That’s the equivalent of 4,500 single-use 16 ounce bottles.

Talk about saving the planet, this little gizmo does exactly that by cleaning pollutants out of your tap water and producing a product that is purer, safer, and tastier than any bottled water product on the market.

Best of all with this system, you’re not filling up landfills with millions of empty plastic bottles, and you’re not polluting the atmosphere with diesel fumes created when these same 16-ounce plastic bottles are transported to market.

The AquaTru is easy to use, with quick-release twist-and-seal filters. The futuristic design can purify a gallon of tap water in just 12 to 15 minutes.

Don’t let the convenient, small design fool you. The AquaTru is a workhorse.

Utilizing a four-stage purification process the tap water first passes through a pair of pre osmotic carbon filters. These twin filters remove larger particles, including rust, sediment, and chlorine. Any other particles in your water are trapped by the carbon filters at this stage.

The third step is an ultra-fine, reverse osmosis filter that cleans out inorganic chemicals like lead, chromium, arsenic, nitrates, and pharmaceutical drug particles.

The final step is the VOC filter where an activated coconut block carbon filter removes hydrocarbons, any remaining prescription drug residue, leaving the thoroughly cleansed water refreshing, good tasting, and safe for you and your family.

2. Brondell H2O+ Countertop Water Filtration System

An innovative three-filter design provides quality filtration without the time constraints of smaller reverse osmosis systems.

The Bronell H20 is a continuous flow filtering system that attaches directly to a faucet, providing as much water as you need without the sometimes cumbersome process of filling and emptying the reservoir from a standalone countertop system.

Brondell H630-H2O

The three-stage filtering system is a patented Nanotrap technology, a process usually found in much more expensive under-the-counter filtering systems.

The small 11.5×4.25×11 inch design takes up only a little of your countertop space but provides a big supply of water.

Simple installation, in under 10 minutes, and equally easy replacement filter makes this a solid piece of equipment for people worried about the pollutants arriving from their municipal water supply.

The three-step process begins with the composite plus filter. This two-step filter traps rust, fine particles, organic material, and sand. It acts as a pre-filtering agent to screen out all the large particles that can flow into your home.

The nanotech filter is the second stage. Composed of cellulose and alumina fiber, it traps particles down to two microns. This clears your water, reducing turbidity.

The final carbon block filter reduces odor, bad taste, and is the final defense against contaminants such as chlorine, organic compounds, and microscopic particulates.

The composite and carbon filters need replacement every six months, while the recommended replacement interval for the nanotech filter is a year.

The filtering process is effective against bacteria, and other waterborne organisms, but doesn’t have an effect on hard water.

If you have hard water, with heavy iron, calcium, or magnesium content, this three process, the physical filter will not remove or reduce the hard water levels. That’s the job of a water softener in large quantities, or for a reverse osmosis system.

Keep In Mind

This three-filter device does not produce distilled water as a reverse osmosis system does, but it is effective at removing smells, harmful contaminants, and bacteria from a water supply.

The advantages are easy to see. This is a low-cost, high-volume filter that is easy to attach, and provides long shelf life with low-cost replacement filters.

3. RKIN Zero Installation Purifier Countertop Reverse Osmosis Water Filter

75 gallons a day, from a countertop reverse osmosis filtration, is all you need to know about the AlcaPure by RKIN. This high-capacity countertop filtration system  approaches the production level of full home units but at a fraction of the cost.

AlcaPure Reverse Osmosis Countertop Water Filter

Weighing just 23 pounds, with a footprint of 14.5×9.5×16.25 this compact unit is a workhorse.

It comes in two varieties, one the AlcaPure edition for countertop alkaline water filter, and the OnliPure edition for zero TDS water.

Both units function the same, they’re just specifically designed to handle the additional challenges water in the PH7 to PH8 alkaline range can present.

This system is small enough to work in any kitchen, it fits compactly in apartments, and it’s even small enough to take with you in your RV.

The supply tank of the unit is located in the front for easy access. Its height allows it to fit under most kitchen cabinets on top of the lower cabinets.

This unit removes chlorine, lead, magnesium, and calcium from water. It is also effective at removing fluoride, other heavy metals, bacteria, and dissolved pharmaceutical drugs which by be dissolved in your municipal water supply.

There is no assembly required, the unit is filled with water by a jug from the tap. In about 15 minutes, you’ll have a half-gallon of pristine water. The system works similarly to a coffee maker.

The four-stage process ensures the best tasting, odor-free water you’ve ever experienced.

Stage one allows the water to pass through a five-micron sediment filter. This removes large particles such as rust, sand, and sediment.

In the second stage, a coconut-based activated carbon block filter removes chemicals, pesticides, and other dangerous dissolved solids floating in your water.

The third stage is the reverse osmosis membrane. The system can produce an amazing 75 gallons of purified water per day.

The final stage applies AlcaPure’s patented post filtering system. In this final step, calcium, magnesium, and other metals common to high alkaline water are filtered out via an ion exchange process.

The resulting water is pure, odorless, chemically free PH balanced.

4. WaterChef C7000 Premium Countertop Water Filter System 1,000 Gallon

The WaterChef C7000 is the least expensive of the countertop water filters we’ve reviewed here. Its easy-to-use design allows a homeowner to connected the filter directly to the kitchen faucet.

It comes with a pre-installed filter, a battery, and a diverter valve assembly. The built-in mechanism sends a warning to you when it is time to install a new filter.

This is not a reverse osmosis filter so some of the chemicals that the reverse osmosis process filters will get through this system. The most notable is fluoride.

Because of its small footprint, many RV users take this unit with them on the road. It is even popular with boat owners. The filtering system works well with questionable water while camping or boating, providing clean, safe water for you to use.

Keep In Mind

Another common application for the C7000 is to place one in the kitchen, the laundry room, and in every bathroom with a sink in the home. The low cost, combined with the high function make it a perfect addition to any home water supply.

All you need is a pressurized water supply, the provided hose, and adapter, and an open space on your counter, the C7000 does all the rest. Great tasting, safe water is just a few minutes away after this unit arrives.

Countertop Water Filters VS Under-Sink Water Filters

We are often asked about the differences between a countertop filter and under-sink filtering systems. Both have their benefits, and depending on your situation, either one could be right for you.

When it comes to ease of installation, maintenance, and price tag, the countertop water filtering system will win out nearly every time. While most countertop filters are reserved to only purify for your drinking water, they can still be used for cooking and cleaning as necessary, which is something most of us will use somewhere down the line. Installation is much simpler and straight forward than the under-sink systems, and they usually do not require any splicing of existing water lines like the under-sink system.

Typically, under-sink systems will require you to attach your existing cold-water line into the filtration system. This allows you to use your existing sink set-up without the need for anything new on your countertops. This is one thing people tend to like more about the under-sink systems; they do not always require a dedicated faucet or a filter to be placed onto your countertop. Under-sink systems are more expensive and much harder to install. This is what makes countertop filters a popular choice over under-sink systems.

Countertop Water Filters VS Whole House Water Filters

When it comes to comparing countertop water filters versus whole-home systems, there is a lot to unpack. Countertop systems are a budget-friendly way for you to provide your home with clean drinking water at your sink, and you can also use it for cooking if you wish. Whole-home systems are much more elaborate. They filter water as it flows into your water pipe systems and provides the filtering capability to every water delivery system in your house. Depending on your specific needs, one may be better for you.

If you are looking for cleaner drinking water and that is your main concern, then the countertop filter will be just fine. The price comparison between a countertop system and a whole-home system is not even on the same planet. Purchasing a whole-home system for simple drinking water needs is over the top and redundant, not to mention comes at the cost of thousands of more dollars.

Whole-home systems are a great option for those who can afford it. If you have the means and the desire to have softer, more purified water for showers, handwashing, and for all cleaning applications, then, by all means, a whole-home system could work. But the added costs do not make up for it if your main concern is drinking water.

What to Consider Before Buying a Countertop Water Filter

Test Your Water!

This is one of the most important things you can do before deciding on the best countertop water filter for you. Testing your water will let you know exactly what contaminants are in your water. This will allow us to combat them in the best way possible.

Knowing exactly what you are dealing with and then comparing the capability of a certain countertop water filter is the best single piece of advice I can give you.


This is something that is often overlooked by homeowners when deciding on a countertop water filter. Remember, the entire filter will be placed on your countertop along with a dedicated faucet in most cases.

You MUST ensure that you have the space to accommodate the filter housing and the height of the faucet. The variation of sizes is huge, but that bigger the filter does not always equal more filtering capability. There are many options out there that pack a mean punch in a small package.

Filtration Capacity

I research filtration capacity no matter what type of water filter I am investigating. The filter capacity refers to how many gallons of water a filter can effectively purify before it needs to be changed.

These can range from 100 gallons into the thousands of gallons range. I cannot stress the importance of checking filter life and capacity. The longer your filter lasts, the more money you will save in the long run, and the less maintenance you will have to do.

Remove Contaminants

A countertop water filter was designed to do this first and foremost: Remove Contaminants! Each filter has a uniquely distinct number of contaminants and toxins that it can effectively remove.

You probably noticed throughout our product reviews; there were thousands of different contaminants that filters claimed could be removed from your water supply. Based on the results of your water test, you will be able to determine the best course of action and which contaminants you should target with your water filter.

Countertop water filters were designed to remove the most found contaminants within typical municipal water supplies. These things include lead, other heavy metals, chlorine, and much more. The one thing to stay be aware of is a filterability to remove total dissolved solids (TDS) from a water supply.

If your water test shows that your TDS level is high, ensure you find a filtering option that can handle TDS toxins. These are not always removed by some filters.


I love the peace of mind that you get from knowing that a trusted party has certified any consumer product. When it comes to countertop water filters, you want to be on the lookout for products that are certified by NSF/ANSI and the Water Quality Association.

NSF/ANSI have several testing procedures that ensure a filter is up to the task when it comes to being safe and effective at removing contaminants. Each type of contaminant group has a standard number for the NSF/ANSI process. For example, if you find a filter that NSF/ANSI certified on standard 42, this means that it is proven to be effective removing lead. The more certifications, the more guaranteed contaminants the filter will remove.

The WQA is another 3rd-party group that does their testing. They run each device through a rigorous set of tests and ensure that they are made of safe, quality parts that will be effective at keeping your water safe. A gold stamp of approval from the WQA goes a long way with many consumers.


One thing people tend to forget about countertop water filters is that even though it is connected to a water supply, they are rated for a certain output of water for each day. Water can be pushed through, but after that ‘limit’, you will see a drop in filter effectiveness.

You want to ensure that for your standard water filters, the filter is not limited to a low amount of water per day. Most humans only need about 2 gallons per day, so this should not be an issue with any quality filter.

If you are using an electric distiller or any battery-powered filter, you do not want to waste energy or time waiting for your water. Some electric distillers can take up to 8 hours to produce a liter of water, which is not the most efficient water filtering delivery system.

Ease of Use

We all like to find products that are easy to use and are still effective. Many countertop filters check that box for us, fortunately. Because there are so few moving parts and there is no real process to get your water other than using the dedicated tap or faucet, countertop water filters are one of the easiest products to use.

Look for any system with a dedicated faucet or a one that works with your existing system, and clean water will be in your hands in minutes.


Plumbing scares a lot of homeowners, and for a good reason! It can be daunting trying to make sure you have the right water line in hand, and you are reconnecting them correctly. Luckily, countertop water filters require virtually no tools to install and can be done in less than 10 minutes.

Typically, the only thing you need to do is screw the water divider or adapter onto your kitchen sink’s faucet, and you have water. If there is any more to it for a countertop water filter that you are considering, run away


There is little to no maintenance to keep up with most countertop filters. We do suggest that you flush the filters every so often with cold water to ensure they are working at their best, but several systems do this for you. One thing you do want to consider when it comes to maintaining your countertop filter is the ease of changing filters. Some systems make it wildly difficult to change filters, and we find that can be a real annoyance when it comes down to it.

Another nice maintenance feature to consider is a filter changing reminder system. These will vary from system to system, but the most important part is to find one that works for you.

Clean Up

The beauty of the countertop system is that there is little maintenance or clean-up! With the countertop filters, the cleanup will consist of getting rid of filters and maintaining your water lines. For filter cleanup, finding filters are recyclable are a godsend. I strongly suggest you investigated these filters.

Maintaining your water lines refers to ensuring that the water line connected to your home faucet to the countertop filter is clean from bacteria and other toxins. Some systems have water lines that are made from anti-bacteriostatic material; these are nice but not necessary. Just run them with clean water every once in a while, and you should be good!

How To Install the Countertop Water Filter?

Unlike whole-home systems, the installation procedure for a countertop system requires virtually zero plumbing experience. When we say that any homeowner can install a countertop filter, we do mean it. When you have decided on the best countertop water filter for you, it will begin by attaching the filter’s water line to your existing sink.



This can be done by unscrewing your faucets endcap; this should only take a few seconds. After that is complete, simply screw the water diverting endcap piece that came with your filter, and that is virtually it.

All you are doing is redirected your water through the kitchen sink and into your filter. If your new countertop water filter has a dedicated tap, just open that valve to let clean water flow!

How do I know when to replace my countertop water filter?

Many systems (not all) have a way to track how long you have been using a certain filter. The simplest but still effective system is a sticker system that allows you to mark down the date of the new filter you know exactly when it was replaced. Some systems use LED light indicators or virtual countdowns.

Is there a countertop filter for alkaline water?

There are countertop filters that can add pH and other minerals to your water to make the water, ‘alkaline.’ If you are looking for an alkaline water ionizer, that is a different product, but you can still get some of those benefits out of top-notch countertop filters.

What countertop filter removes arsenic?

Lots of them do! Many systems that remove fluoride will also remove arsenic. iSpring systems are a great option for arsenic removal.

Which countertop filters are affordable to maintain?

I would steer clear of water distilling filters and go with the standard. You also want to find one with a long filter life. The cleanwater4less model checks these boxes.

Which countertop filter reduces to 0.3 Microns?

0.3 microns is a good number to strive for with filters. This means that toxins sized 0.3 or higher will not get through the filter. Most systems are rated anywhere for 0.3 to 0.5, the APEC, APEX, Berkey, and iSpring systems can handle this.

Do countertop water filters work for all kitchen faucets?

Yes, they are compatible with all kitchen faucets. Those that connect directly to the kitchen faucet had adapters provided for all the major models of faucets.

Do countertop water filters store water before drinking?

Yes, and no.  Those that are standalone, and must be filled manually with a water filter pitcher all have storage areas. Those that connect directly to a faucet only allow flow through, without storage capacity.


Everyone can benefit from a countertop filtering system. No matter how good your water quality seems to be, it can always be improved by either a filter, a reverse osmosis system, or a combination of the two.

Modern city water supplies have many hidden dangers, dangers that you can’t taste or smell, but are there nonetheless. A countertop water filter can provide a little security for you and your family knowing you’re drinking the best water available.

Your choice for the best countertop water filter comes down to the features you need for your home.
