Installing a countertop water filter in your kitchen is one of the easiest ways to enhance your home’s drinking water. Even if you think your tap water is perfectly safe to drink, you might be surprised about the hundreds of contaminants that come in every glass of tap water. A countertop water filter works to eliminate these contaminants, and some even work to alkalize your water and enhance its pH levels.

This guide provides you with everything you need to know before buying a new water filtration system for your home. Each of the reviewed products below work to remove chemicals and offer reliable filtration to give you and your family clean drinking water at all times.

How Countertop Water Filters Work

The process of filtering water may seem simple, but as it turns out, it is actually very complex. Filtering water, according to NSF International standards, isn't easy. There are 3 main steps for the water to go through, including mechanical filtration, water softening, and carbon filtration. After that, some countertop filters offer additional steps like alkalization and remineralization.

The most important steps, though, are 1 to 3. Mechanical filtration means that the water is mechanically pushed through the small pores of a filter, which helps to minimize larger impurities like rust and sediment.

Water softening uses ion exchange technology to remove heavy metals and toxins that are responsible for making your water harder. And carbon filtration uses activated carbon to remove organic contaminants like herbicides, pesticides, and disinfectants like chlorine.


Alkalization & Remineralization

If you opt for a water filter that comes with extra filtering powers, you can enjoy drinking water that has been alkalized and remineralized. Alkalization is the process of changing a water’s pH to make it more alkaline and less acidic.

Research shows that the ideal pH level of drinking water is at least 8.5, but most tap water has a much lower pH level than this. Lastly, look for a water filter that remineralizes the water and adds back any minerals that might have been lost during the filtering process.


Benefits of Countertop Water Filters

The main advantage of investing in a countertop water filter is that you'll have easy access to drinking water in its purest form. There are tons of health benefits that come along with drinking filtered water simply because a filtration system helps to minimize harmful toxins and chemicals, like chlorine, lead, and fluoride.

On top of that, using a water filter can give your water a more pleasant taste and smell. Lastly, turning to water filtration is much more environmentally-friendly than purchasing filtered water that comes in bottles, plus there it is much more cost-efficient. A recent study showed that the average cost of a 16-oz bottle of water ranges from $1 to $2, while the average price of 100 gallons of filtered water is about $0.11.


Buying Guide: Countertop Water Filters

Type of Filter

The type of filtration system you choose should be your first priority when shopping around for the best countertop water filters. It is suggested that beforehand you do a test of your tap water to see what contaminants it contains, and then use this list and compare it with the contaminants removed by a water filter.

The most common contaminants in tap water are chlorine, fluoride, and lead, but you might be surprised to find that you’ve also been drinking trace amounts of pesticides.

Filtration Capacity & Filter Life

Every filter comes with a unique capacity and filter life. The capacity refers to how many gallons of water the filter is capable of filtering before it’s time to invest in a new one. This capacity determines the filter life. Typically, every 40 gallons of filter capacity can be translated into about 2 months of use.

This means a filter with 40-gallon capacity should be switched out after 2 months, an 80-gallon capacity can last 4 months, and a 120-gallon capacity can last 6 months. The best water filter pitchers typically come with a 40 to 120-gallon capacity, but countertop water filters are designed to last much longer. You should be able to find a filter that comes with at least a 6-month lifespan, if not 1 year.

Flow Rate & Filter Micron Rating

There's nothing more frustrating than wanting to fill up your reusable water bottle, but you're in a rush, and you don't have the time to watch the water slowly trickle through the filter. The solution is to find a filter with a fast flow rate, but even when you do that, you need to be realistic about how fast a filter can operate. There are several steps involved in filtering your water, so you’ll need to have some patience.

The other consideration along with flow rate is a filter’s micron rating. According to the Wix Filters FAQs page

a micron rating is a value assigned to a filter, indicating that filter's ability to remove a certain size of particle.”

You’ll want to find a filter that comes with a low micron rating. The lower the rating, the smaller the filter's pores, which means even the tiniest molecules won't be able to pass through.

pH Alterations

Drinking filtered water that alters the pH of tap water is becoming more common. You’ve probably seen bottles of alkalized water on the shelves of your local grocery store. Alkalized water has been altered in pH levels to make it less acidic, which is linked to many health benefits. Healthline says that ,

"not all alkaline water is equal and that it “must also contain alkaline minerals and negative oxidation-reduction potential (ORP). ORP is the ability of water to act as a pro- or antioxidant.” 

If drinking alkaline water is on your list of things to do, look for a countertop water filter that has a negative ORP rating, since this means that the water is more antioxidizing in nature.

Water Quality

Before even considering a top-rated countertop water filter, you must consider the quality of your tap water. Water all around the world ranges in the contaminants it contains, its pH levels, and whether it is hard or soft. In order to change your water for the better, you first must know what needs to be done. To gauge the quality of your water, you can purchase a water testing kit on Amazon.

Ease of Installation

One of the perks of choosing a countertop water filter as your primary filtration system is that most models are easy to install. That said, some come with more difficult installation than others, and some are tricky when it comes to changing out the filter with a replacement. The easiest type to install is the faucet model that attaches directly to the kitchen faucet, and it's ready to use.

Cost Overtime

The initial cost of a high-quality countertop water filter should be overlooked. Over time, you’ll save a massive amount of water by eliminating bottled water from your day-to-day life. Although tap water is the cheapest way to stay hydrated, it is not worth the health risks that come along with consuming contaminants and toxins.

That said, you should still consider the costs of the filter over time. No filtration system on Earth doesn't require replacement filters, so check to see how long each filter is expected to last and how much each replacement will set you back. It's worth it to pay a slightly higher cost for a filter that is meant to last one full year than one that will only provide you with 6 months of clean drinking water.

Certifications

There are a few water filter testing organizations that you can trust, including the NSF, ANSI, and WQA. The main stamp approvals to look for come from the NSF, which is the most reputable certifying organization for water filters in the world. Be wary of products that make claims like "meets NSF standards," because this doesn't mean it has actually been certified.

A gravity-fed water filter works exactly as you would expect. The water is loaded in from the top of the filtration device and fed through using the forces of gravity. The perk of choosing the best countertop gravity water filter is that you can use it virtually anywhere, no power source required. This is just one of the many advantages of choosing the Royal Berkey Gravity-Fed filtration system.

The Berkey features powerful purification that works not only to filter the water but completely purify it. It is capable of removing up to 99.999% of viruses and bacteria as well as protozoa, inorganic minerals, heavy metals, and pharmaceutical drugs. The economical and long-lasting design has an impressive 6000-gallon capacity before needing to be replaced. Most filters of this nature have between 1000 and 1500-gallon capacity, so there’s really no comparison.

There are several size options to choose from, the most popular one being the 3.25-gallon capacity. There is also a 1.5, 2.25, 4.5, and 6-gallon option, so the one you choose depends on how many people will be using the filtration system. The 3.25-gallon is capable of hydrating 2 to 4 people for one full day, which makes it an excellent solution for camping trips and weekends away at the cabin.

Although the Royal Berkey allows users to drink confidently virtually anywhere, this is not the ideal solution for everyone. It’s a great choice for outdoor adventurers, but if you’re looking for a permanent filtration solution for the home, this might not be the one. For that, it makes more sense to choose a faucet attachment like the Apex or New Wave.

Pros
  • Easy to use gravity-fed design
  • No power source required
  • Powerful purification
  • Impressive filter capacity
Cons
  • Not ideal for permanent home filtration

Some say that the 10,000-gallon capacity is a bit of an overstatement, while others claim that this filtration system truly does last that long. The only thing to be aware of is that the flow rate will decrease a bit over time, but this is true of any countertop water filter. Sediment and mineral build-up can be expected, especially if your tap water is riddled with impurities.

Even if this model doesn’t last you the full 10,000 gallons, you should have no trouble getting your money’s worth. Especially once you calculate the cost of drinking bottled water (and the costs to your health of drinking tap water), you’ll see that there’s no better option than the cleanwater4less in terms of value for price.

Pros
  • Sleek stainless steel design
  • No replacement filters required
  • Long lifespan
  • Easy diverter valve installation
Cons
  • No fluoride filtration
  • Only 97% of contaminants removed

If you’re looking for a high-tech kitchen countertop water filter that delivers sparkling clean water, check out the Cuckoo CP-MN031BK Direct Flow filtration system. The Cuckoo looks great on any countertop and produces crystal clear water with the push of a button. While filtering your water, the machine also works to remineralize it with magnesium, calcium, and potassium.

The Cuckoo does this by using 3 separate filtration cartridges: Carbon, Nano, and Mineralizer. With these 3 filtration methods working together, water is free from harmful bacteria, viruses, tastes and odors, heavy metals, and other contaminants, all without losing out on the essential minerals necessary for the human body to function at its fullest.

Aside from its powerful filtration abilities, the best part of the Cuckoo is its sleek countertop design. This is why so many people are willing to pay a higher price tag. The machine itself looks similar to a Keurig, but all that is required for operation is the push of a button.  There is minimal setup that takes the average person about 15 minutes, but once done, drinking filtered water has never been easier.

Here’s what the manufacturer has to say about replacing the filter:

“Cuckoo’s filter replacement System informs you when each filter needs to be changed and specifies the exact filter to change. Cuckoo worked hard to develop the simplest filter change on the market – No twisting, turning, hassle or leaks.” 

The only downside to replacing the filters is that they don’t come cheap, but they certainly get the job done when it comes to filtering, remineralizing, and alkalizing your tap water.

Pros
  • Sleek countertop design
  • Remineralizes and alkalizes

The debate over whether or not fluoride in water is safe will continue until the end of time. Time Magazine says that,

“the U.S. began adding fluoride to some public water supplies in the 1940s, in an effort to strengthen teeth and prevent decay… At high doses, fluoride can actually damage people’s teeth, according to the World Health Organization—and some research suggests it’s also tied to more serious side effects, including bone cancer and cognitive impairments.”

So although there is still a lot of debate regarding fluoride, research is suggesting that it might not be as beneficial as they once thought. For this reason, so many people are choosing to filter out fluoride along with the other common tap water contaminants. Filtering out fluoride is made easier than ever with the Home Master TMJRF2 Jr F2 countertop filtered water dispenser.

The Home Master dispenser delivers highly pure water through a 3-stage filter that removes up to 93% of fluoride, chlorine, and other chemicals. The efficient space-saving design fits nicely next to the kitchen sink, even if you’re short on space. Installation is simple and takes only minutes before the dispenser is ready to use. It’s highly portable, so you can move it from one room in the house to another.

If you’re focusing on fluoride elimination from your water, this is a great choice. But the downside is that this filter isn’t as effective at eliminating a long list of contaminants as some other models we’ve covered. It focuses on fluoride and chlorine, but if you want contaminant-free water in every aspect, you might consider one that has a 99.9% filtration rating instead of just 93%.

Pros
  • Efficient space-saving design
  • Effective for minimizing fluoride
  • Advanced multi-stage filter
  • Perfect for any sink top
Cons
  • Low filter capacity
  • Short filter lifespan

Countertop Water Filter Styles

  • Sink-Top Filter
    The sink-top filter, also referred to as a faucet filter, is a filtration system that attaches directly to the kitchen faucet. It allows you to easily switch between filtered and unfiltered tap water, which makes it easy to go from washing dishes to filling up a glass of water that is suitable for consumption.
  • Gravity-Fed Filter
    A filter that is gravity fed requires no electricity or connection to a water supply. It is a freestanding unit that sits on a countertop and filters water that has been poured into the top of the unit. This is amazing for camping trips or visiting areas with no running water.
  • Water Distillers
    Fresh Water Systems says that a water distiller works by “converting water into vapor before condensing it and returning it to a liquid state. During the evaporation process, impurities like bacteria, heavy metals, and arsenic are eliminated because they are unable to turn into steam. As the water transitions from a liquid to a gaseous state, these contaminants are left behind in the boiling chamber.”

Countertop Filtration Systems Explained

Carbon Filtration

Carbon filtration is an effective method not only for minimizing contaminants but eliminating any unpleasant tastes or odors. It works by using activating carbon to attract impurities from the water before passing it through to the drinkable water chamber. This is a great method if your municipality disinfects water with chlorine and chloramine.

Ceramic Filtration

Ceramic filtration is the best method if the water in your geographic location is known to contain bacteria, parasites, and cysts like Giardia. These have a low micron rating, which means that they can capture tiny microscopic parasites that many filters aren't able to eliminate. This is thanks to the porous surface of ceramic, which most bacteria are unable to penetrate.

Ultrafiltration

Ultrafiltration is one of the most effective water filtration methods since it filters the water multiple times. It uses an extremely fine membrane that has a low micron rating, just like ceramic filtration. It is capable of reducing nearly all water contaminants.

Water Distillation

All distilled water goes through the same process. The water is heated up and turned into steam. This is extremely effective since chemicals, viruses, and heavy metals are unable to convert into steam. Once the steam is converted back into a liquid state, it is free from nearly all impurities.


All About Water Contaminants

Physical Contaminants

There are many types of drinking water contaminants, but one of the most common is contamination from sediment or organic material.  Physical contaminants like this typically enter a water supply due to soil erosion, and they can affect the color, taste, and safety of your drinking water. These contaminants are relatively large, unlike chemicals and bacteria, so they are easy to filter out.

Chemical Contaminants

It’s scary to think just how chemicals are contained within your tap water, but many of these chemicals are put there on purpose. Municipalities use chemicals like chlorine and chloramine to disinfect the water.  Although this disinfection is necessary, it is suggested that you do whatever you can to filter out these chemicals. They are linked to some long-term health problems, plus they can leave an unpleasant taste or smell in your water.

Biological Contaminants

The EPA says that "biological contaminants are organisms in the water. They are also referred to as microbes or microbiological contaminants. Examples of biological or microbial contaminants include bacteria, viruses, protozoan, and parasites.”

Consuming harmful bacteria can be life-threatening. Bacteria is much more difficult to filter out than sediments or chemicals, which is why you should invest in a filter with a low micron rating.

Radiological Contaminants

Radiological contaminants emit radiation due to unstable atoms from unbalanced protons and neutrons. The most common radiological contaminant is lead. The CDC says that common sources of lead in drinking water are 

“lead pipes, faucets, and plumbing fixtures. Certain pipes that carry drinking water from the water source to the home may contain lead. Household plumbing fixtures, welding solder, and pipe fittings made before 1986 may also contain lead."


Countertop Water Filters Compared

  • Vs. Whole House Water Filters
    Using a whole house water filter will deliver filtered water throughout the entire house, but installing a whole house filter isn't easy. It is also extremely costly, so if you're looking for a simple, affordable solution, a countertop water filter is the better choice.
  • Vs. Under Sink Water Filters
    An under sink water filter is advantageous in the sense that it is entirely out of sight. However, the advantages stop there. An under sink water filter is more difficult to install, plus it is easy to forget about filter replacements when your filtration system is out of sight, out of mind.
  • Vs. Water Filter Pitchers
    A water filter pitcher is extremely convenient and works by pouring water into a pitcher, then the filtration mechanism inside filters out contaminants. Many people prefer water filter pitchers since they can be conveniently stored in the fridge and keep your drinking water cold. The problem, though, is that these need to be refilled continuously, and the filter has a shorter lifespan than the best countertop water filters.

Installing or Changing Countertop Systems

Most countertop water filters are straightforward to install. There is a minimal setup process that takes just a few minutes, especially ones that attach to the kitchen faucet. Some models require you to use an adjustable wrench, but many manufacturers include a small plastic wrench in the package. Here are the basic steps involved to install your new countertop filtration system:

  • 1
    Place the filter close to the sink so that the included water line can connect the filter and the kitchen faucet.
  • 2
    Remove the faucet aerator. This is easy; you should be able to find the steps with your faucet user manual.
  • 3
    Faucets with external threads can connect directly to the filter. For a faucet with an inside thread, you'll need to use the filter adaptor to connect the two.
  • 4
    Follow the filter’s manual to connect the diverter to the faucet. Water will flow normally from the faucet until the diverter is turned. Once turned, water will flow from the filter spout.

Frequently Asked Questions

What is remineralization?

Remineralization is the process of adding minerals back to the water that has been filtered. This is a useful step since most filters work to filter out everything, which means both the good and the bad. By remineralizing the water, you’ll be able to add back the minerals that were lost in the filtration process.

Is tap water chlorinated?

Government municipalities add chlorine to their water sources to disinfect it. The Water Quality and Health Council says that 

“the EPA requires treated tap water to have a detectable level of chlorine to help prevent contamination.”

The argument is that chlorine at low levels is completely safe, but it is still best to filter out chlorine from your home’s tap water.

How can I test my water quality at home?

Lifehacker says that to test the water in your home, simply test it yourself.

“You can buy a test kit from your local home center or online,” says Lifehacker. “The kits usually come with a package of strips that contain reactants that change color to indicate the presence of various contaminants in your water.”

How often do I have to change the filters?

This depends on the filter you choose. Filter lifespan depends on its filtering capacity. For every 20 gallons of filter capacity, you should be able to get a full month of use out of your filter. Look for a filter that features at least a 120-gallon capacity, which generally lasts about 6 months before a replacement filter is needed.

What should I do with the used filters?

Depending on your filter of choice, there are 3 options: reuse, replace, or recycle. The most common method is a replacement, which is necessary once your filter has reached its filtering capacity and becomes too clogged to operate correctly. Just find a compatible filter for your filtration system and follow the replacement instructions provided by the manufacturer. Check the guidelines in your area to see if it’s possible to recycle the filter rather than just throwing it in the trash. 

How should I maintain these units? How do I flush them?

It’s extremely common for bacteria to buildup within a filtration system, so flushing the filter is a good idea. This is as easy as running the filtered water for 20 seconds before collecting drinking water for yourself. Not only does this minimize bacteria from your drinking water, but it also helps to maintain the unit.

What happens if I do not replace my water filter?

The most common problem that occurs from failing to replace a water filter is clogging. Contaminants will continue to collect as you use the filter, and eventually, there will be so much contamination that the filter won’t be able to push clean water through. You should always follow your unit’s guidelines for replacement.

What is the best system set up for well water treatment?

The most common well water contaminants include heavy metals like arsenic, lead, copper, and chromium, as well as fluoride, which is found in almost all water supplies. Because well water contains so many contaminants, you’ll want to find a filtration system that uses at least two methods of filtration, like activated carbon and ion exchange. This won’t be difficult to find when you choose from one of the countertop water filter reviews listed here.


Conclusion

In conclusion, we’ll do one more recap of our top pick for the best home water filter countertop model, the APEC filtration system. This filter utilizes a 4-stage RO filtration process and is effective for eliminating 99% of impurities that are commonly found in tap water. There’s zero installation and lifetime support provided by the APEC company, but best of all, this filter is expected to last one full year before a replacement is needed.
