If you’re looking for easier access to clean drinking water, may we suggest picking up a countertop water filter? The best countertop water filters are not only easy to use and store but can also reduce exposure to detrimental contaminants often found in tap water, such as lead, chlorine, and pesticides. Studies show that lead found in water, even at low levels, can harm our health1, and chlorinated water could be linked to colorectal cancers2.

In addition to making our water cleaner, countertop water filters can help promote hydration by making high-quality water readily available—and proper hydration is essential for regulating body temperature, preventing infections, and delivering nutrients to cells. Needless to say, water filtration systems are a worthwhile investment.

Using research, product reviews, and expert insight, we’ve found the best countertop water filters available today. Read on to learn more about the importance of using a countertop water filter, plus how to pick the best one for your lifestyle and needs.

The best countertop water filters of 2023:

What is a countertop water filter?

A countertop water filter is a water filtration system that (as it sounds) sits right on your counter. Many are easily transportable and can be placed on shelves or inside refrigerators, too. These systems are often affordable, easy to use, require little-to-no installation, and effectively reduce the number of contaminants in tap water.

Who should use a countertop water filter?

Anyone interested in staying hydrated or who would like easier access to cleaner, safer drinking water will benefit from a countertop water filter. “Drinking filtered water is important for many reasons,” shares Dr. Peter Michael, M.D., a practicing physician and the Chief Medical Officer of VUE. “It can help improve the taste and smell of water, reduce the risk of dehydration and constipation, and help maintain skin, hair, joints, and digestive tract health.” He adds that filtered water can lessen the risk of consuming contaminants and impurities, including chlorine, copper, lead, and more, that are typically found in tap water.

Countertop filter systems are also an excellent environmentally-friendly way to cut back on buying plastic water bottles.

How to use a countertop water filter.

How you use a countertop water filter depends on which model you choose. “The most important thing is to fill it with water and make sure you replace the filter when the manufacturer suggests,” says Constantin Geambasu, owner of Water Rehab in Phoenix, Arizona. He recommends placing the filter close to your sink, so you can fill it with water easily.

What are the benefits and drawbacks of a countertop water filter?

Michael emphasizes that countertop water filters are beneficial because they help remove contaminants from water, such as chlorine, lead, and pesticides. “This can help to improve the taste and odor of the water while also reducing the risk of health problems associated with these contaminants,” he says. He points out that the costs involved with these kinds of filters may be a drawback, adding that “There may also be risks from the filters themselves, especially if they’re not maintained properly.”

Geambasu shares that countertop filters do have limitations. “They are a cost-effective way of making good water taste better, but they cannot make bad water taste good, and they cannot make a water supply potable if it wasn’t already,” he explains. “A whole house water filtration system is always the preferred option; however, this option is not realistic for every person.”

How to choose a countertop water filter:

It’s important to keep in mind certain details when choosing the best countertop water filter for our personal needs.

First, consider what size filter will work best for your space, and the filtration process you prefer. List out any features (such as a water indicator or dispenser) you’d like your filter to come with. Geambasu recommends purchasing a countertop water filter that has at least a three-stage filtration system. “A three-stage system will often include two carbon filters and one sediment filter,” he explains.

How we picked:

Unique features, such as water quality indicators and push-button dispensers, help elevate user experience. We analyzed each pick and highlighted these as pros.

Top quality products last longer and are safer to use. We made sure to include high-quality products from brands that people trust.

We dug through hundreds of reviews to gain a better understanding of what people like (and dislike) about each filter. Reviews helped us get an idea of how people interact with these products day-to-day.

Not everyone has the same amount of countertop space, which is why we made sure to include a range of size options on our list.

It is easy to deal with as you don’t have to soak the filter first, and the filter is quick to flow, so you don’t have to wait 10 hours to get filtered water. It leaves the water tasting pure. I don’t taste anything weird with it until it is actually time to change the filter which at that point it’s not the filter’s fault.”

What our testers say:

“I recently installed this in my kitchen (install is an overstatement—it’s ready to use in just a few minutes!), and it has made my life a lot easier. I’ve tried using water filter pitchers and faucet filters in the past, but neither worked well for me. Because of this, over the last year, I’ve been drinking bottled water almost exclusively—I know, way too much plastic! I’m happy to report that this new kitchen gadget not only looks pretty cool on my countertop, but it’s also allowed me to cut back on my water bottle buying. I like how simple it is to use—add water to the reservoir, press a button, and voila!—and that it’s made by brands I trust.” — Brittany Natale, contributing writer

Are countertop water filters safe?

Countertop water filters are safe to use, but must be maintained regularly to make sure they are in optimal working condition. Filters that aren’t in tip-top shape may have negative effects on your health.

What is the healthiest way to filter tap water?

Michael shares that the healthiest way to filter tap water is by using a reverse osmosis filtration system. “Reverse osmosis is a type of water filtration system that is capable of removing nearly all contaminants from tap water, including bacteria, viruses, and other harmful chemicals,” he explains.

Which water filter removes the most contaminants?

Although the amount of contaminants each water filter removes depends on the model, filters that use reverse osmosis often reduce the highest amount of contaminants. Be sure to read through the description of each filter before purchasing.

How can I naturally purify my tap water?

Natural ways to purify tap water at home include using a filtration system, or boiling your water. It’s vital to remember that even though each of these methods can reduce the number of contaminants found in tap water, they may not remove them completely.

The takeaway.

There’s no doubt about it: hydration is vital to our health. The best countertop water filters can make clean, safe drinking water more accessible and help keep you hydrated throughout the day. They can also help you cut back on buying plastic water bottles, which is a win for our planet, and for us.
