Get the Best Faucet Water Filter for Your Home: A Comprehensive Buyer's Guide

Stop right there! We have selected the ten best faucet water filters on the market. However, it's important for consumers to research and learn as much as possible before making their choice. Here is more information about faucet filters.

Before we dive into the details, let’s have a quick overview of what faucet filters are – and how they work.

What is a Faucet Water Filter?

A faucet water filter is a system that attaches to your existing faucet and filters the water before it reaches the tip. It consists of a filter housing unit that screws into the base of the faucet and an internal filter. The internal filter, which is made of mesh layers and a specialized filter media such as activated carbon, ion exchange, or KDF, removes impurities from the water as it runs through the faucet. The faucet filter dispenses purified water wherever it is needed.

How Faucet Filters Work

Inside the housing unit is the filter, which purifies the water. There are several filtering methods used in different faucet filters.

Mesh Layers

Mesh layers, made of ceramic or polypropylene, catch sediment and grit in the water. However, they can't catch smaller chemical compounds.

Activated Carbon

Activated carbon captures chlorine and other chemicals through adsorption. However, its effectiveness decreases over time because of its finite surface area. However, with a finite surface area, activated carbon filters have limited lifespans, and become less effective over time.

Ion Exchange Method

Ion exchange removes charged particles from water, specifically to soften hard water. While it removes heavy metals such as lead, it also removes beneficial minerals like calcium ions.


KDF, or kinetic degradation fluxion, uses a copper-zinc blend to remove heavy metals and chlorine from water. It works through redox reactions.

The Benefits of Using a Faucet Filter

Faucet filters are useful for many reasons. Here are six reasons why you should consider adding one to your kitchen setup:

Purified Water

The main reason to use a faucet filter is to have easy access to purified drinking water. Statistics in the United States show that water quality is decreasing, and contaminants such as fluoride, lead, and grit can be found in tap water. A faucet filter ensures that you and your family have clean water to drink. Don't risk drinking water from old lead pipes or contaminated by farm runoff – get a faucet filter instead.

A Cleaner Taste

A refreshing glass of cold water is one of life's simple pleasures, but chemical contaminants in our water supply can make it taste less enjoyable. Faucet filters remove chlorine and other contaminants, improving the taste of the water. Some even add minerals like calcium to create the pure taste of water we remember from childhood.

Reducing Your Plastic Footprint

As people become more environmentally conscious, reducing our use of plastic is a priority. Disposable plastic water bottles contribute to landfills and pollution in our oceans. A faucet filter allows you to have bottled-quality water at home, eliminating the need to buy plastic water bottles.

Easy Installation

If you're not comfortable with DIY projects, you'll be happy to know that faucet filters are easy to install. No handy skills or tools are required. In fact, faucet filters are one of the easiest home water filter systems to install – you can have filtered water flowing in under 10 minutes.

Flexible Filtration

Faucet filters also offer the most flexibility at home. They have easy-access on/off switches that allow you to switch between filtered and unfiltered water. In contrast, whole-house filter systems filter all the water in your home, including water used for watering plants or washing the car. A faucet filter only filters the water you use.

Great Value For Filtered Water

Faucet filters are also some of the most affordable home water filter systems. When you consider the cost of buying bottled water, a faucet filter can even save you money in the long run. Choose a faucet filter to filter your own water and save money while helping the environment.

Key Factors to Consider When Choosing a Faucet Water Filter

To make the best decision for your home and family, consider these factors before buying a faucet filter.

Your Purification Needs

Water quality can vary greatly depending on location. Some countries add fluoride to their water supply while others don't. Contaminants such as lead, chlorine, and arsenic can also vary from state to state, as can pesticides and herbicides from farm runoff. It is important to identify your purification needs before purchasing a faucet filter by finding out what is in your water supply.


Don’t think water has a taste? You’ve been drinking too much Coca-Cola! Contaminants and minerals in water can alter its taste from chemical to clean. Some filters can also add minerals such as sodium and calcium to improve the taste while removing chemical contaminants. Some faucet filters may only remove sediment and add flavor, which can be a good value option if you aren't concerned about water purity.


Ensuring that a reputable body has certified a faucet filter gives you peace of mind. Many brands have obtained independent lab reports from the National Sanitation Foundation (NSF), while some big-name brands argue that NSF certification isn't necessary. Decide what is important to you when it comes to certification.

Construction Quality

Construction quality affects the longevity of a water filter system and can also affect the aesthetic of your kitchen. Plastic is often used to house the internal filter system due to its lower cost, but it's prone to cracks, breaks, and leaks. Stainless steel is more durable and stylish, but also more expensive. If you choose a plastic faucet filter, make sure it's made with BPA-free plastic to prevent chemicals from seeping into your water supply.


Most faucet filters mount onto your existing faucet, making installation easy. However, it's important to check if your faucet is compatible with the filter. Handheld faucets and pull-down faucets may not be compatible and may require an under-sink water filter instead.


Faucet water filters are easy to install, requiring only a screwdriver. However, make sure to prime the filter media by flushing water through it for up to ten minutes according to the manufacturer's specifications. This removes sediment and ensures optimal performance before use. Tapping your filter into the water line can also be a consideration, as it allows for a continuous water supply without needing to turn the filter on and off.

Flow Rate

Flow rate refers to the volume of water that your faucet can produce. In the United States, water-saving measures limit faucet flow rate at 2.2 GPM (gallons per minute) at 60 psi. (1)

Without a water filter, the average flow rate of a faucet is between 1 and 1.5 GPM. Faucet filters direct water through filter media, which slows flow rate down. Standard filter flow rate is around 0.5 GPM, which is half the flow rate without a filter.

Maximize the flow rate your faucet filter can handle, within your budget, to save time at the sink.

Filter Lifespan

One important thing to consider when buying a faucet water filter is that filters have fixed lifespans. Filter lifespan varies dramatically, from around 100 gallons to 300 gallons or more. The longest-life filters often limit the contaminants they target, which may not provide broad-spectrum filtering. Filter lifespan can also be affected by the initial quality of your water supply. A high TDS (total dissolved solids) level can halve filter lifespan.


A warranty can provide peace of mind in case your filter is faulty. Warranties range from one year to lifetime. It's important to note that when purchasing a faucet filter, you are also getting a filter housing system and an internal filter. These products often have different warranties, so it's important to distinguish between them.


Purified water brings us closer to nature and can provide relief from the stress of modern life. It also reduces our reliance on single-use plastic, helping to protect the planet. If you are concerned about your health, it is important to filter lead and chemicals from your water. Faucet filters are a convenient and affordable way to do this.

Thanks to easy installation and use, making it simple to provide your family with pure water. Overall, faucet water filters are a necessary addition to any home.
