Best Faucet Water Filter

If you’re on a mission to find the best faucet water filter you’re in the right place!

Water is the substance of life. Humans are made up of at least 70% water, and we must drink lots of safe and delicious water each day to maintain optimum cell health and to hydrate our bodies. When you’re properly hydrated, your quality of life and peace of mind can be drastically improved.

While most places boast clean and safe water piped straight into homes and businesses, additives and harmful chemicals may seep into the makeup of the substance you drink the most. It’s important to your health to know what’s in your drinking water, and it’s equally imperative to have the cleanest, most pure water possible. This often means adding a water filter to your faucet or sink.

Many homes have a faucet-mounted water filter that sifts out potentially harmful additives, such as chlorine. While types of filters and quality will vary, drinking filtered water is usually much more tasteful than drinking straight from the tap. It can be difficult to detect that your neighborhood or local water supply tastes “off” until you’ve been drinking filtered water from a faucet-mounted filter for some time. But once you get used to the taste of clean, delicious water, you won’t ever want to revert back to drinking anything unfiltered.

What is a water filter?

Water filters can work in three basic ways, but ultimately, they have one common goal: removing impurities from a water supply. Use of a water filter will improve the safety and enhance the taste of water. Water filters undergo a rigorous testing process before they hit the market. Knowing what contaminants can be present in your tap water will help you select the right kind of water filter for your home.

Filters will have a physical barrier, a biological process, or a chemical process by which they clean and purify water. Water filters are used in virtually every capacity – for homes, gardens, swimming pools, crop irrigation in commercial farms, and public drinking water supplies. If there’s water involved, chances are there’s some sort of filter. Even fish tanks have to have water filters!

This is a buyer’s guide for faucet-mounted filters. Before making the case for using those water filters, let’s look at the four major types of water filters available for sale.

Different Types of Water Filters

Different types of water filter systemsUnder Sink:

Known for its ability to filter large quantities of water, the under the sink filtration system requires quite a bit of space underneath your sink (presumably, in a cabinet). A DIY homeowner can install many under the sink filtration systems, but it’s always best to have a plumber look at things if at all possible.


Perhaps the easiest type of water filter to install, a faucet-mounted filter is screwed onto the aerator on your faucet. You can usually do this without a trained professional. In fact, many people DIY their faucet-mounted filters. Faucet-mounted filters are easy to install, and they filter out a variety of substances and additives often found in tap water. Your water will typically taste much better and be purer after adding a faucet-mounted filter to your home.

Whole House:

If you need to decrease sediment and chlorine in a water supply, the whole house system is exactly what you’ll need. Only to be installed by professionals, your whole house will have purified and delicious water! This is the most complicated of the water filters to have installed, but it is sometimes necessary. The quality of your local water supply, pipes, and delivery method into the home will dictate how your whole house system is installed, and how it will ultimately work best to benefit the water needs in your home.


Pitcher filters, or carafes, are probably the most readily available type of water filtration. The flow-through rate can be a little low and frustrating if you’re re-filling your pitcher on the go. The small pitcher size can’t always accommodate the water needs you have, but generally, the pitcher type of water filter is the simplest and most user-friendly design. These filters must also be replaced after some time and heavy use. Many homes will have pitchers of filtered water in the refrigerator. These are excellent additions to any home, but they are also somewhat annoying to continually refill. If you have a big family, you might need more than one pitcher if you want cold, filtered water all of the time!

The Case for the Faucet Mounted Filter

Best faucet water filter


The best reason for installation of a faucet-mounted filter on your sink at your home or business is that you can usually do it yourself with a little research and perhaps a bit of practice. First, you’ll unscrew the aerator on the end of your faucet. Unscrew from the threaded tip of your faucet, and place the faucet-mounted filter into place. Then, make sure you screw in your new faucet mounted filter appropriately. That’s it!
Another big plus of the faucet-mounted system is that you can switch between filtered and unfiltered water. Turning off the filtration system when you don’t need to use it will elongate the life of your filter. These water filters incorporate a physical barrier such as charcoal and must be replaced occasionally. Select a faucet-mounted filter that keeps track of the life and cleanliness of your internal filter. This will need to be changed in order to restart the life cycle.

Faucet Water Filter Pros: They’re very easy to install. The ability to switch the filter off when filtered water is not needed increases filter’s life.


The most common complaint of those with faucet-mounted filters is that the filtered water suffers from a low and slow flow. The second most common complaint is that not all faucet-mounted filters are created equal – if you buy one for your home, please make sure it is compatible with your faucet size. This can be more difficult than you think!

Faucet-mounted filters don’t work for faucets that feature a pull-out sprayer. Make sure you’re ready to purchase your faucet-mounted filter before moving on the next section!

Faucet Water Filter Cons: The filtered water suffers from low pressure flow. Finding a filter that’s compatible with your faucet size may be challenging.


There are many types of water filtration systems, but none so convenient as the faucet-mounted sink filters. Although other filtering options will give you whole house filtering or a pitcher full of water, the faucet-mounted (especially those with on/off features) systems will work perfectly for your everyday needs.

While we know you have many options for faucet-mounted water filtration systems, the five reviewed above are among the best and most recommended on the market. The most important piece of your choice should be choosing a water filtration system that removes harmful impurities, making your water safer and more life-giving to drink. If you can improve the taste, that’s a bonus, too! Many of the reviewed items will provide improved water quality with drastically improved taste.

If you’re a DIY homeowner, most – if not all – of these water filtration systems can be installed by yourself. Additional instructions and how-to videos may be found online for most products. If you think you need to call in a professional to help you install or decide on a product, make sure that you are paying the lowest reasonable price, and that you place a premium on trust. Your water quality could depend on it!
