Best Faucet Water Filter

To the uninitiated, lack of access to clean water might seem like solely a third world problem. However, situations like the water crisis in Flint, Michigan, reminds us just how close to home it is.

According to a recent research review, about 9-45 million Americans get their drinking water from sources that violates the national Safe Drinking Water Act. This report considered historical data on water consumption from the U.S. Environmental Protection Agency (EPA) over the last three decades.

Yes, compared to worldwide standards, the U.S has relatively safe water. However, as proved time and time again, random cases of contamination can pop up in a random city at any time. The potential health risks associated with contaminated water is why more than 4 in every 10 American homes use some form of a home filtration system (according to a study by the EPA.)

Filtering water also helps to protect you against chemical contaminants. Harmful chemicals can exacerbate health conditions like stomach flu. Furthermore, severe cases of chemical contamination can lead to more chronic conditions like neurological disorders or even some cancers.

Home filtration systems or smaller localized options like refrigerator water filters, water filter pitchers, and faucet water filters can go a long way in protecting your family from these potential health hazards. These filtration systems catch contaminants like sand and debris, chlorine and organic compounds, as well as potentially poisonous metals like iron, chromium, and mercury. Water filters also help remove that chlorine taste and any foul smells.

Faucet-mounted water filters offer a convenient, cost-efficient, and environmentally friendly way to filter your drinking water at home before use.

Thanks to their two-step carbon-powered filtration system, capable faucet water filters can remove up to 70 different types of water pollutants.


How to Faucet Water Filters Work?

Faucet water filters use a filtration cartridge that uses a two-stage cleaning process to rid your drinking water of impurities and contaminants.

First Stage: Sediment Removal

The first stage handles large debris chunks like sand and rust. This filtration layer typically consists of a non-woven filtration screen with at least 0.5-micron openings.

Second Stage: Carbon Filtration

For an even more thorough clean, the second stage filtration is handled by a stub of activated carbon. Activated carbon cleans water via a process called adsorption, whereby pollutant molecules in the water line get caught inside the pore structure of the carbon substrate.

Carbon filtration can catch microbes like bacteria and fungi that escape conventional physical filters. Thanks to its active substrate, carbon also traps an array of chemicals that include chlorine, lead, pesticides, and herbicides, as well as several harmful volatile organic compounds. The active layer also helps to remove taste and odor from water.

The longer the water stays in contact with the activated carbon layer, the more contaminants get trapped in the carbon substrate. Hence, many water filters slow down the flow rate of water to ensure more exposure to the carbon layer. As a result, a filtered water line may produce a significantly slower water flow than a filterless one.

Faucet Water Filter Pros

Compared to other water filter types, faucet water filters bring several advantages that include::


Your typical water filters are big bulky things that often create a series of extra steps you must take to get drinking water. For example, with water filter pitchers, you have to fill up the container manually regularly. Moreso with refrigerator water filters, where after emptying the water reservoir, you have to wait a while for it to fill back up.

Thankfully, faucet water filters save you the added wait time. Turn on your faucet, and you get access to a never-ending stream of drinking water immediately. Another big plus with faucet filters is that their small size makes them extremely portable and an excellent road companion. Bring your faucet water filter on the road, and you will have clean water everywhere you go.

Easy Install

Unlike specialty home filtration system that requires complex installation processes, most faucet water filters feature a “direct hookup” setup that you can get up and running in minutes. You should be able to install these filters in little time, even if you are not tech-inclined.

Low Maintenance

Save for changing the filter cartridges every few months; faucet water filters are maintenance-free.


Faucet water filters cost a fraction of the price of other water filtration solutions. The cost of filter cartridges changes is also on the low end compared to filter changes for other water filtration systems.


These filters do not produce wastewater like other filtration solutions; hence, they conserve more water and prevent wastage. Using faucet filters with tap water is also significantly more eco-friendly than buying bottled water.

Ability to Switch Between Filtered And Unfiltered Water

Some faucet water filters let you switch between filtered water and unfiltered water with the push of a button. This feature is particularly useful if you want to compare both to check the efficacy of your filter. It is also a great way to check if the unit is due for a cartridge change.

Faucet Water Filter Cons

One potential con of faucet water filter solutions is that they are not as effective as more comprehensive filtration systems at tackling the smallest contaminants.

Also, faucet filters only filter water at one point in your home. Hence, for larger homes, you may need several units to cover your space, and this can quickly amp up the price.

Choosing The Perfect Faucet Water Filter: Best Features

Cartridge Change Sensor

One feature you should look for when buying a faucet water filter is the inclusion of a cartridge change sensor light. Over the lifespan of your unit, the primary maintenance operation is changing the filter cartridge. Hence, a notifying sensor significantly improves your experience as it lets you know when a change is due and ensures you have clean water always.

360-degree Swivel

A swivel head on faucet filters significantly improves convenience, especially in the kitchen sink. A fixed head is not a problem until you need some flexibility, and then it’s everything.

Design and Finish

If you are perfect decor fanatics like we are, you should take special care to select a sleek-looking faucet filter model. The ideal unit should match the aesthetics of your kitchen and blend in nicely with your other fixtures and appliances.

Water Flow

As part of the cleaning process, faucet filters typically slow down the water flow considerably to ensure a thorough carbon-powered clean. If substantial water flow is crucial, you should opt for one of the models that support an enhanced flow. However, slower flow improves filtration, so if it’s not a significant inconvenience, we recommend getting a slow-flowing filter.

Maintenance Costs

Faucet filters are some of the cheapest water filters available. However, what you should be wary about is the price of regular filtration cartridges changes. You will need to change cartridges every 1-3 months, so units that use cheaper replacements will significantly reduce maintenance costs.

How to Install a Faucet Water Filter

Most faucet filters feature a pretty straight forward installation process. They often do not require special tools and should take only a few minutes to set up.

To install your new faucet water filter, follow these steps:

Unscrew the Faucet Aerator

Remove the aerator by hand or with a wrench if it is more sturdy. Remove any washers too.

Clean Mineral Buildup

Depending on the age of your faucet, you may have metal and mineral deposits under the aerator. You can clean the buildup with warm water or with some vinegar.

Attach the Filter

Attach the filter to the faucet and twist it until it locks into place. Depending on your faucet filter’s build, you may need an adaptor to connect to a male/female faucet. For some models, this adaptor is included in the package.

Fix and Flush the Cartridge

Now connect the cartridge and turn on the tap. Let the water run for at least 5 minutes to flush out any excess carbon before tasting the water.
