The Top 9 Faucet Water Filter of 2021!

Updated for 2021!

Don’t like the taste and smell of tap water? You’re not alone. Only 38% of people think tap water has a “good quality” taste and smell, according to the Consumer Council for Water’s Attitudes to Tap Water Report.

A filter eliminates those unwanted tastes and odors. It also promotes health for you, your wallet, and the environment. That is why more people than ever are switching to faucet water filters.

Shopping for a faucet water filter is daunting. There are hundreds of different options, each marketing benefits from FDA-approved food grade water filtration to easy installation. We are here to make shopping simpler. Here are our top nine picks for the best faucet water filters for 2020.

Why Use a Faucet Water Filter?

Faucet water filters ensure clean drinking and cooking water for you and your family. According to the Water Quality Association, this affordable home water treatment is in more than four out of every ten American households. Here are some other reasons why people are investing in faucet water filters.

Remove Contaminants

Even the best tap water contains some chemicals. The most common combination is fluoride and chloride. These elements are harmless in small amounts but become problematic if you consume them regularly. Studies link fluoride and chloride to increased levels of rectal, colon, and bladder cancer.

Faucet water can have arsenic and aluminum, too. Arsenic is a dangerous chemical that can cause cancer, skin lesion, diabetes, and cardiovascular disease. Aluminum is present in poorly filtered municipal tap faucet water. Researchers have connected the metal to increased risks for Alzheimer’s disease, hyperactivity, and learning disabilities.

A faucet water filter removes organisms, in addition to individual elements. That includes filtering parasites like cryptosporidium and giardia, which lead to gastrointestinal disease. Using a faucet water filter causes a 33% drop in the incidence of both.

Promote Nutrient Absorption

A faucet water filter system can improve your absorption of essential nutrients. For instance, if you use an alkaline ionizer water filter, the pH of the drinking water is slightly higher. The filter separates the incoming water using electrolysis into acidic and alkaline components.

Drinking ionized water increases the rate that your cells absorb water and nutrients. These functions are essential for proper metabolic function and overall health. The ionization of tap faucet water ensures you have adequate hydration, whether you are exercising or running errands.

Proper nutrition and hydration pay dividends for the body in multiple ways. Faucet water filters improve your body’s natural detoxification because you more readily process chemicals and toxins. The filters limit the toxins that go into your body. What does enter, you eliminate through sweat and urination.

More Affordable Than Bottled Water

The adage is that you should drink eight glasses of water per day. That equals two gallons for a family of four. It also adds up to a lot of money if your family only drinks from plastic water bottles.

One of the best cases for faucet water filters is their savings. Researchers estimate drinking bottled water costs a family of four $3,114.67 per year. A year’s supply of faucet water filters only costs $236.10. That means you could save $2,878.57 per year with a water filter.

Investing in one of the best faucet water filters can save a boatload of money. You come out ahead even if you purchase the most expensive system. That is on top of the health benefits and improved taste and odor.

Water filters provide cost savings for the environment, too. Americans throw away more than 35 billion plastic bottles per year, with only a quarter of them recycled. The remaining 75% goes into landfills and oceans, which hurts the local ecosystem.

Encourage Water Drinking

Having tasty tap faucet water at home encourages everyone to drink more. This distinction is one of the primary benefits of water filters. People often subconsciously hydrate less than they should when there is sub-par water at home and will drink better tasting water.

Hydration affects every function of the body, from metabolism to overall health. Water filters make it easy to maintain hydration, whether we are having a glass of tap faucet water or cooking a meal. This benefit is paramount for children that are still developing physically.

Frequently Asked Questions

Do faucet water filters really work?

Yes, faucet water filters work. The real question is, how do they work? Each filter manufacturer uses a different series of physical and chemical processes to remove particulates and other microscopic contaminants from the water. Here is an overview of the four most common methods:

Reverse Osmosis

A reverse osmosis filter removes contaminants with water pressure. The faucet mount water filter forces the tap water through a semipermeable membrane into an area with lower water pressure. When the water hits the screen, particles get stuck. Note that reverse osmosis is not effective on solvents, pesticides, and certain metals.

Ion Exchange

An ion exchange filter softens water by removing metal cations, like magnesium, sodium, and calcium. The chemical process releases ions and exchanges them for unwanted ones like heavy metals in the water. The method extracts these elements and leaves you with the best tasting faucet water.

Steam Distillation

Steam distillation is a natural process that includes heating and cooling water. Most contaminants have a higher boiling point than water, which means they are left behind when the water evaporates. The steam later condensates and turns back into purified water.

Activated Carbon Filters

The odds are your household water filter uses activated carbon. It is one of the most popular and affordable ways to clean water. Charcoal has a broad and porous exterior, which makes it an ideal surface to trap unwanted particulates.

Charcoal acts like a magnet inside the faucet mount water filter. It traps lead, mercury, irons, and other volatile organic compounds internally. The activated carbon filter even catches elements like chlorine and fluorine through a chemical reaction when the water interacts with the charcoal.

Are faucet water filters with the National Sanitation Foundation (NSF) certification better than non-NSF filters?

Looking at certifications is one way to find the best faucet water filter. The NSF is an accredited, independent third-party certification body that tests faucet water filters. The goal is to make sure the manufacturers meet public health and safety standards.

Most reputable water filter producers have NSF certification. That does not mean that a product is inferior without the label, though. Water filter manufacturers have to pay NSF fees for the review and subsequent endorsement. Some companies opt to produce highly-quality filters without certification.

How do I install or replace a filter?

The installation and replacement of water filters vary by manufacturer. Many of the best faucet water filters are easy to install and even easier to replace. Most models also have an indicator light that tells you when to put in a new filter.

If you want to install or replace a filter, unscrew the threaded mounting nut that connects the device to your faucet. Twist the cover off of the faucet mount filter and insert the filter. Replace the back cover before screwing on the nut.

Each new filter cartridge has a brief acclimation period. You should run cold water for five minutes through the filter for the best results. This period flushes the screen and gets rid of unwanted substances.

Can I run hot water through a filter?

Running hot water through your filter does more harm than good. Many water filters have a thin membrane of polypropylene or polyester. This mesh is responsible for filtering out the potentially harmful particles.

Hot water causes the woven mesh to loosen, which undercuts the filter’s effectiveness. Natural string and cellulose filters are slightly less vulnerable to heat. Most manufacturers recommend not using water over 100 degrees.

How do I clean my faucet water filter?

You probably either have a reverse osmosis or activated carbon filter. Reverse osmosis filters require two levels of cleaning because they extract contaminants at multiple stages. Activated carbon filters use a similar cleaning process, but it’s more straightforward.

Drain the water from your filtration unit to start cleaning the reverse osmosis filter. Detach the pre-filter and reverse osmosis membrane before applying the cleaning solution. Use two or three tablespoons of unscented bleach, if the manufacturer does not include best practices for cleaning,

Scrub the two sections until you no longer see accumulation. Run water through the membrane to double-check the cleanliness. Reassemble the water filters once they work to your satisfaction.

Activated charcoal filters require a bucket of clean water at room temperature. Add two cups of muriatic acid—be careful, this is extremely caustic—to the water and stir. Place the filter in the mixture after rinsing it with a hose.

Wait five days for the solution to remove all the contaminants. You may need to resoak the filter before rinsing and installing it. You should clean your faucet water filter at least once per year.

What should I look for in the best faucet water filter?

The best faucet water filter is the one that works for you. While there is no definitive list of essential criteria, there are characteristics to look for in today’s crowded market. Here is a list of features to consider when you shop:

Filter Cartridges

Filter cartridges are the most important part of faucet water filters. They remove the contaminants from your drinking water. The best models remove up to 70 different materials, including mercury, lead, and iron.

All filter cartridges have a finite lifespan, usually expressed in terms of gallons. Many filters have capacities of 100, 200, or 300 gallons. You need to replace the filter once they reach that point, so they remain effective.

Always respect the manufacturer’s recommendation for when to change a filter. They perform multiple tests before releasing the product. That includes finding the point when the screen shows diminishing efficiency because of wear and tear.

Filter Change Sensors

There are two primary types of filter change sensors: light and day counting. Light sensors are more common. They start with a green color to indicate the filter is operational. The light changes to orange or yellow when the screen nears the end of its life expectancy.

Order or install a new cartridge during this period. The filter may turn red when it reaches its maximum filtering capacity. The filter ceases functionality at that point.

A day counting sensor is more common on water pitchers. It calculates the days since you last changed the water filter. Most day counting sensors need replacement every three to six months.


Faucet filters come in two styles. The first one allows the filter to rotate on an axis conveniently when you use the sink and need to move it. The second style swivels vertically along with the faucet. Some people find this style more comfortable to use as it provides greater access to the sink.

You should also consider the size and finish of the water filter. Size does not affect performance, but it does influence how much space you have. Cleaning dirty plates may become a headache if you have to work around a bulky filter.

Most water filters have a metallic or plastic finish. The metal housing is significantly more durable and provides a chic aesthetic to the kitchen. Plastic exteriors are prone to leaks and cracks but are more affordable.

Ease of Installation

The best tap faucet water filters are easy to install and do not require tools. Some may need an adjustable wrench to unscrew the aerator on the faucet. Water filters that require tools may include them in the product packaging.

Can I recycle my faucet water filter?

Many manufacturers let you send the faucet water filters back to them for proper recycling. Other companies include a set of instructions so you can dispose of the screen yourself. Put it in the trash if you have doubts about whether or not the filter is recyclable.

Recyclable filters typically require several days of drying. It helps recycling centers ensure that the screen doesn’t damage other recyclable goods, like paper or cardboard. Once you dry the filter, wrap it in plastic and ship it to the appropriate manufacturer.

Your buying guide may recommend placing the activated charcoal filter in the garden or on a gravel pathway. We strongly recommend avoiding this practice. Opening the water filter allows unwanted contaminants to reenter the environment and is especially problematic for local plants and animals.
