Best Faucet Water Filter

Depending on where you live, sometimes the tap water can be pretty undrinkable. Whether it’s a bad taste, weird smell, or discoloration, many people opt for bottled water.

This can get really expensive in the long term, and it’s not environmentally friendly to say the least.  Thankfully, there’s a better option. That option is a faucet mounted water filter.

These filters can be installed right onto the faucet itself.  They filter the water instantly once you open the faucet, so you have pure filtered water whenever you need it.

It’s so much more convenient and faster than a water filtration pitcher, which does the same thing but just a lot slower.

In our list, you will find some of the best options available on the market when it comes to faucet mounted water filters.

Most faucet water filters are pretty small and not intrusive to your kitchen.

They’re also really quick and easy to install, and they don’t require any replacement of the faucet itself, it just fits right onto the preexisting faucet.

This makes it a perfect option for those who rent houses or apartments and can’t do any construction work or renovation to their living space.

Why Get A Faucet Water Filter?

So why do you need a filter for your faucet? Let’s look into some of the main reasons why you should invest in one of the faucet mounted water filters on our list.

Safe, Great Tasting Water

A faucet water filter will remove numerous contaminants from your water that could otherwise make it foul tasting or even dangerous to drink.

Depending on where you live, the water could be heavily chlorinated, and it could be abundant in harmful heavy metals such as mercury, lead, and arsenic.

Some water filters have inbuilt materials to increase the pH of the water to make it more alkaline.  This can be beneficial if you live in an area with acidic tap water.

The bottom line is that a faucet water filter ensures that the water you’re getting from your kitchen or bathroom sink is safe and tastes fresh, crisp, and clean every single time.

Reduce Plastic Waste

Reduce the amount of single-use plastics you use by investing in an inexpensive adapter for your faucet rather than buying bottled water.

Additionally, bottled water isn’t just bad for the environment but it can take a toll on your wallet in the long run.

With a faucet water filter, you can get bottled-quality water right from your own home for the fraction of the cost.

Filtered Water On Tap

Pitcher filters are just as effective at removing any contaminants from tap water, but they take a long time to refill and filter the water.

It can take at least a few minutes to just make a few cups of filtered tap water.  A faucet water filter, on the other hand, provides filtered tap water instantaneously.

If you need to make a lot of filtered water every day for drinking, cooking, washing etc. you would be much better off with a faucet water filter rather than a pitcher filter.

However, it’s worth noting that a faucet water filter does not provide sufficient filtration if the water in your area has heavy pollutants, dangerous contaminants, or heavy chlorination, then you should look into purchasing an under sink or countertop filter that has a bigger capacity and a stronger filtration system.

It’s also important to mention that faucet water filters won’t be compatible with all kinds of faucets.  Some modern pull-down styles of faucets won’t be able to fit a faucet mounted water filter on them.

All that being said, if you need an inexpensive, quick, easy, and portable option for water filtration, then a faucet mounted water filter is a great choice.

Buyers’ Guide

There are a few different things you should be aware of before deciding upon which faucet water filter is the right one for you.

These include the material from which the housing is made, in addition to the type of filter cartridges they use.

Also, you should be aware of the installation requirements of the unit, and if they match to the shape and overall design of your kitchen faucet.

Water Contaminants

Depending on where you live, tap water can be full of contaminants such as pesticides, microorganisms, chemicals, organic compounds, heavy metals and even pharmaceuticals.

The level of drinking water contamination varies by community, so it’s important to research into your own water supply through the Environmental Working Group’s National Drinking Water Database.

Some of the chemicals and contaminants that may be affecting your drinking water include:

  • Chlorine and chloramine
  • Fluoride
  • Lead
  • Agricultural chemicals
  • Industrial chemicals

Type Of Filtration System

The type of filtration system used in your faucet water filter will determine the level of filtration,  Some types are more effective than others.

Reverse osmosis filters are the most effective and are able to remove up to 99% of contaminants.

They cannot be attached to a faucet, however, and carbon filters are used for most commonly used for faucet mounted filters.  Active carbon is what you should be looking for in a good faucet water filter.


Most faucet-mounted water filters have either a stainless steel or a plastic enclosure.  A lot of manufacturers also offer different finishes, such as a plastic enclosure with a chrome finish.

A stainless steel is recommended for its durability.  Plastic faucet water filters are less expensive, and they are less prone to leakage.

A stainless steel filter matches the look of your kitchen sink more than a plastic one.

Flow Rate

The flow rate means how much water can pass through the filter per minute. This is measured in gallons per minute.

Most faucet mounted water filters have a flow rate of around 0.5 GPM.  Some may be slower than others, depending on the design and the type of filtration.

Filter Usage And Lifespan

The filter cartridges in faucet mounted water filters have to be replaced every once in a while.  Depending on the amount of usage, a filter will last approximately 3 to 4 months before it starts becoming less effective.

Most replacement cartridges will have a capacity of 100 to 200 gallons. It’s a good idea to replace the filter to keep the faucet mounted water filter working effectively.

Filter Change Sensor

Some faucet mounted water filters have a light that indicates when the filter cartridge needs replacing. This is a handy feature to have to remind you to replace your filter cartridges every few months.
