Best Faucet Filter Reviews (2020 Update)


1. Waterdrop 320-Gallon Long-Lasting Water Faucet Filtration System

If you’re looking for an affordable water filter which you can fit and forget, look no further than this Waterdrop model.

With a long-lasting filter capable of treating 320 gallons of tap water before it needs to be changed and scoring 5 stars from over 65% of reviewers on Amazon, we don’t think this budget faucet water filter can be beaten overall.

While the Waterdrop doesn’t have as many features as some of the other filters we rated, it can be used with hotter water than many of its competitors – up to 122 fahrenheit – and will produce 0.5 gpm of flow.  Combined with a tool-free filter change mechanism and everything you’ll need to fit the filter to most faucets (they even threw in some spare washers!), we rate this the best on faucet water filter for anyone looking for a quality, reliable, and downright effective option to clean up the drinking water in their home.


  • Long filter-life
  • Easy installation 
  • Switch between filtered and unfiltered water 
  • Low price


  • Light on features compared to some other models
  • White plastic construction isn’t the best looking filter on the market


2. PUR PFM800HX Horizontal FM 1 with Bluetooth

Just missing out on our vote for the best faucet mount water filter, the PFM800HX for PUR, a household name is water filtration is loaded with features.

As well as being certified to filter 99% of lead as well as reduce over 70 other contaminants, the in-built Bluetooth technology within this faucet filter lets you track how much water the unit has filtered, helping you keep your family hydrated. 

The traffic light warning on the filter body lets you clearly see how far away your next filter change is and the CleanSensor system even gives a “change filter soon” light to give time to grab a replacement from the store before the filter stops working.

With its sleek style, 0.5gpm flow rate and cutting edge technology, we think this filter will be a hit for many buyers.


  • Excellent filtration of contaminants
  • Stylish design 
  • Packed with features and smartphone compatible 
  • Switch between filtered and unfiltered water 
  • Trusted manufacturer with a good reputation
  • 2 year warranty


  • One of the more expensive units in our test
  • 100 gallons filter life means filters will last 2-3 months, less than others on test
  • Filter can only be used with water up to 100 fahrenheit

3. Engdenton Stainless Faucet Water Filter

A stainless steel filter housing, 0.5gpm filtered-water flow and the highest overall Amazon review score of any filter in our test at 4.6 stars, this filter has satisfied many buyers.

Made from food-grade stainless steel and with an outstanding 320 gallon filter-life, this filter certainly felt the most robust in our test and with a filtered flow rate of 0.65 gpm this filter is well-made and high-performing.

The only drawbacks we could find were the price and the unit’s bulky size.

If you’re willing to spend over $50, this Engdenton model could be the best faucet filter on the market – only its price has kept it from the top of our list.


  • Excellent flow rate and filter life
  • Solid construction
  • Extended life


  • High purchase price
  • Bulky size
  • Not certified for lead decontamination as other models

4. Culligan FM-15A

This Culligan on-faucet water filter has been around for some time, so they must be doing something right.

Affordable, with a filtered flow rate of 0.5gpm and a 200 gallon filter life giving 4-6 months of use, this unit ticks all the boxes for any homeowner looking for a straight forward faucet filter and online reviews suggest it will stand the test of time.


  • Tool-free installation
  • Popular unit with filters widely available
  • 200 gallon filter life
  • Over 1,500 5 star Amazon reviews


  • Basic features for the price
  • Plain design 
  • Plastic casing not as durable as metal competitors

5. Kabter Faucet Mount Water Filter System

This Kabter on-tap filter is rated for the highest water temperature of all of faucet-filters in our test and is one of the few units available which can filter water from both the hot and cold taps making it ideal for cooking.

WIth an easy to turn lever to switch between filtered and unfiltered flow, we particularly like that Kabter have given the plastic filter-cartridge housing a chrome finish, helping it to blend in with your sink and faucet.

With a competitive price and compact design, we think this filter has a lot of features and will be a popular selection for buyers who are looking for a subtle but effective filter, capable of handling hot water from the faucet.


  • Plastic coated chrome blends on with faucet
  • Side-mounting allows extras clearance below faucet
  • Filters up to 158 fahrenheit, letting you filter both hot and cold water


  • Does not filter fluoride
  • Chrome finish can wear over time

6. Brita Basic Faucet Mount

A no-nonsense faucet filter from one of the biggest brands in household water filtration, theBrita Basic Faucet Mount filter isn’t the prettiest model we’ve seen but its reliable and comes with all the features you’d expect from a water filter.

Its plastic casing makes this filter one of the lightest in our line-up, and it shows Brita’s approach to making filters which are more about function than looks.

As shown by the BPA free casing, Brita have put all of their thought into making a filter which focuses on producing the cleanest water and have ditched any aspects which don’t contribute to function.

With a filter change light, filtered/unfiltered switchover and 100 gallon capacity, we’re sure the look of this filter will put off some buyers but for the benefits it offers and the budget price this filter will be a popular choice for many buyers.


  • Filter change light
  • Removes 60+ contaminants 
  • Filters easily available


  • Plastic construction means this filter is more prone to breaking than its metal competitors
  • Basic white plastic casing stands out in a more stylish kitchen

7. DuPont WFFM100XCH

Another household name delivered a solid faucet water filter – DuPont brings this subtle unit to the market with a broad range of features which filter contaminants, removes odour and improves taste.

We really liked the Antimicrobial coated cartridge housing on this faucet filter, it’s certified proof of lead removal and its subtle design means that it blends smoothly into most kitchens.

Everything you need to install comes in the box with this tap filter, even down to the plumbing tape!

Ultimately, although the WFFM100XCH offers some strong benefits we found this filter to be pretty unremarkable.

A solid, if unspectacular offering, we certainly wouldn’t recommend against this filter but others in our test offer better value and more features. 


  • Subtle design 
  • Affordable price
  • Antimicrobial casing protects your filter from bacteria
  • Everything you need comes included


  • Other models available with more features for the same price 
  • Some reviews claim the casing looks different out of the box to the photos
  • 100 gallon filter capacity is the minimum we’d expect from a faucet filter

8. PUR PUR-0A1

The second offering from PUR in our guide, the PUR-0A1 lacks the extensive features of the PUR PFM800HX but will likely be far more appealing to most buyers.

A 3-month (approx 100 gallon) filter life, LED filter change light and gorgeous design, the PUR-0A1 is a subtle, effective and easy-to-install faucet filter which meets the needs of most families and will last a long time.

The stainless steel styling blends into the kitchen and the well-placed lever allows easy switching between filtered and tap water.

The plastic construction is unnoticeable under the stainless steel effect and while we know it probably won’t last forever, we love it anyway.


  • Affordable filter from a well-known brand
  • FIlter change light
  • Stylish design


  • Expensive compared to others with the same features
  • Short filter life 
  • Plastic construction

9. DuPont WFFM350XCH Electric Metered 200-Gallon Deluxe

The second faucet filter in our review from DuPont, and we couldn’t leave this one out.

The standout feature is the in-built water meter, which shows exactly how much water the unit has filtered – great for health conscious-families who want to track their hydration.

With its bulky design and price tags towards the higher end we know this faucet filter won’t be for everyone, but if you’re looking for a filter to help you track your intake, this filter could be the answer you’ve been looking for.


  • In-built water meter is the main benefit
  • DuPont design styling is subtle


  • Bulky unit
  • Reduces water flow by approx. 50%
  • Many reviews suggest the unit can fail or leak earlier than you’d expect to replace the unit for the price

10. Instapure F5GWW3P-1ES

With sleek white design and 200 gallon filter-life, this Instapure filter looks good on paper however it feels cheap and we’ve heard multiple reports of difficulty fitting the filter to the faucet causing leaks, as well as manufacturing issues.

While there are also happy customers, we think this model is best avoided and given the number of other models which outperform the F5GWW3P-1ES for the same price.


  • Good filter life
  • Sleek design


  • Difficult to fit without leaks
  • Feels cheap and easy to break

Faucet Water Filters Buyer’s Guide

WIth their ever increasing popularity, more and more faucet-mount water filters are becoming available and with so many to choose from, selecting the right tap filter can be confusing at best.

Lucky for you, we’re here to help.

How do faucet water filters work?

Filtration Process


Faucet water filters go to work as soon as you turn on the tap.

As water from the faucet enters the faucet-filter, it passes through a mesh screen within the casing, immediately blocking larger particles such as sand, grit and rust from reaching your glass.

Once it has passed through the mesh screen, the tap water moves through the filter itself.

At the first stage water passes through a less dense section of the filter block which traps any dissolved sediments, before being directed into a dense press of activated carbon.  

As it moves through the activated carbon its chemical properties attract contaminants within the tap water, meaning that as the water passes through these compounds remain within the filter block, bound to the carbon molecules in the filter.  

The compressed block of activated carbon is often treated with an antimicrobial which kills bacteria within the water as it passes through

The filter block within a faucet water filter is usually a compressed block of activated carbon, made up of tiny fragments of tightly pressed organic material to give a larger surface area.  . 

It is this surface area which with use over time becomes clogged with contaminant molecules which were previously dissolved within the water, reducing the effectiveness of the filtration process and requiring a new filter to ensure that the water filter continues to remove chemicals, bad tastes and odours.


Contaminants Removed 


Odours and bad tastes from tap water are caused by chemicals or compounds within the tap water itself.

Common complaints are chlorine taste (from the filtration process by the water company), funny colours (caused by bacteria within the water) and contamination as a result of industrial operations in the areas where the water is drawn from the ground (such as lead, mercury and pesticides).

A good-quality water filter will reduce all of these compounds, improving the quality and taste of the tap water in your home

It is common for the best water filter faucets to remove over 70 contaminants from the water supply, as well as killing bacteria and improving the taste.

Lead, mercury, pharmaceuticals, pesticides, pollutants are all among the impurities which a faucet water filter can remove

Most faucet water filter manufacturer publish test results of the filtration process and removal success of different contaminants through their filters, and if you have specific concerns about the water quality in your area a quick Google search will allow you to find and compare the results from different faucet-filter models so  you can ensure that the filter you choose is right for your area.

Benefits of faucet water filters

We’ve already mentioned that faucet-mount water filters are growing in popularity, but why?

We go through the main reasons that more and more families are buying water filters to improve their drinking water.


For less than $15 you can buy a faucet-filter which will improve the taste, cleanliness and quality of your tap water for 2-3 months.  

An American family could drink over 2 gallons of water a day.  When the common alternatives to contaminated water are bottled water at $1.50 a bottle, or a home filtration system costing thousands of dollars to install and hundreds of dollars a year to maintain, you can see why more and more Americans are turning to cheap, readily available faucet-filters to solve this problem.

Low maintenance

When correctly installed faucet filter needs no maintenance and with some filters on the market lasting upwards of six months, this is the only time you’ll have to worry about it.

Easy to Install

Most faucet water filters can be fitted inside 5 minutes with no tools and most of the top brands include everything you need in the box.  It couldn’t be simpler!

Improves water quality

Even in areas where tap water is safe to drink, we all have a friend whose water tastes funny and has a strange colour to it, and we dread it.  Faucet water filters remove bad tastes and discolouration at the tap.

Fit most standard faucets

Most faucets are suitable for the installation of a faucet water filter and all of the top brands include a range of adaptors with the unit to ensure that their unit is compatible with your existing tap.

Economical to operate

Unlike whole house filtration systems, there are no purging cycles or overflows which can waste water, and they use no electricity to operate meaning the only running costs are replacement filters and in units with more electronic features, the occasional battery.

Stylish Designs

With so many on the market, faucet filter manufacturers are spending more time than ever ensuring that their filters look good as well as performing well.  Finding a faucet filter that doesn’t look good in your kitchen is virtually impossible! 

What to look for when choosing a faucet water filter

The best sink water filters are packed with features.  

Our helpful guide explains some of the most common and the most valuable to help you understand the filter that will suit you best.

Filter change sensor

Using a filter past its life is the quickest way to render it useless, so it is important to know when the filter needs changing so that you can guarantee that your tap water quality remains high.

Many models in our reviews include filter change lights showing you clearly the status of your filter and several even have an early warning light showing you that your filter is almost ready to be changed, to give you plenty of time to pick up a replacement and ensure that your drinking water is only ever of the highest quality.

Filter longevity

Filter longevity is an important consideration when choosing your water filter.  Having to change the filter block every 2 months is going to cost you far more than a model which can last 6 months.  

Overlooking this simple difference could more than double your faucet filter running costs and if you want to maximise the benefit of your faucet filter, it’s worth checking this simple factor.

Type of filtration

The type of filtration that your faucet filter offers is going to have a strong influence on the model you choose, especially if you live in an area where there are known contaminants such as lead or pesticides.  In order to make the best decision, once you have narrowed your search to a few models look up the manufacturer’s instruction and check their filtration results to make sure that the faucet-filter you choose filters the contaminants you’re concerned about.

Lead and fluoride are the hardest to filter, and it is always worth checking that your water filter can remove these from the water supply.

Ability to swivel

If you’re going to attach a filter to your faucet, you’re going to want to make sure that it’s not in the way the next time you want to wash your biggest pan.  

 By choosing a faucet filter that swivels, you eliminate this problem altogether and don’t lose any clearance in the sink ,without having to worry about removing the filter every time you cook a Sunday Roast!


The size of the filter will affect the clearance over the sink, as well as the overall look of the filter.  If you are choosing a filter without the ability to swivel this is especially important. 


Unless you’re Mark Zuckerberg, price is going to be a key factor in which filter model you choose.  Remember that the cost price isn’t the only expense you’ll have over the filters lifetime – once you have chosen a filter it is worth checking the cost of replacement filters to make sure that you don’t end up spending $50 to replace the filter in your $15 faucet-filter!


The appearance of your water filter is something which you will have to look at every time you turn on the tap – make sure you like it!  Filters are available in a wide range of finishes, and are common in white, stainless steel and chrome. Once you have decided on the features you want in a filter, check to see what finishes are available so that your filter blends in or adds to the style in your kitchen, instead of taking away from it!

Ease of installation

While faucet-mount water filters are generally very easy to fit to most taps, many don’t even require tools.  If you’re not confident doing small jobs around the home, make sure you look for a faucet filter with tool-free installation to make sure that everything goes smoothly.

How to install a faucet water filter

Faucet water filters are designed to be very easy to fit, and generally follow the same process.

Although this might be slightly different depending on your faucet, we have laid out the steps to fit your faucet-filter below:

Remove the aerator from the end of your faucet

At the end of your faucet, exactly where the water comes out there will be an aerator – a small disk which can be removed.  You may need a tool to do this, depending on the tap you have installed but most simply unscrew.


Clean the surface


Using a cleaning agent or vinegar, clean the area around the aerator with a cloth to make sure there is no residue or scale build up which might affect the new faucet filter’s seal onto the tap.


Fit the adaptor (if required) 


With the manufacturer’s instructions in hand, check to see whether your tap will need an adaptor to connect the new faucet filter.  These adaptors will come in the box with the new filter. Once you have established which adaptor you need (if you need one), fit this to the faucet according to the manufacturer’s instructions.


Fit the faucet filter


Attach the faucet filter and ensure that it is twisted into position.  The filter should be level and fully pressed on to the faucet (or adaptor, if you used one).


Flush the filter


Once you have fitted the faucet filter, ensure that the lever is switched to filtered water and turn on the tap.  Run the tap for 5 minutes to flush out the filter.




Check all around the filter to ensure there are no leaks… your filter is ready to use.

Faucet water filter cleaning and replacement

Clean your faucet filter with a damp cloth and warm soapy water when necessary.  Be careful not to use abrasive sponges or cleaning pads to avoid damaging the finish of the filter.

To replace the filter, follow the instructions within the manufacturer’s user guide.  This usually involves turning off the water from the faucet and twisting the filter body to reveal the filter block inside.  

Replace the filter with a genuine replacement from the manufacturer to maintain your filter’s warranty and reassemble by twisting the body back into place.

Turn the water on at the tap slowly to ensure there are no leaks, and then turn the faucet on fully to flush the new filter for 5 minutes before use.


After reviewing these products, it is clear to us that the faucet water filter market is improving every year as more and more people turn to these simple devices to improve the taste and quality of their tap water.

An affordable, effective and easy solution to contaminated, odorous or stale water, homeowners no longer have to rely on expensive whole house filtration equipment or store-bought bottles to enjoy fresh, clean water.

Although faucet-mount water filters aren’t for everyone and won’t work with every faucet, we highly recommend you check out our suggestions at the links above to see in-depth product descriptions  and see how a faucet water filter can help you improve the quality of your drinking water, without costing the earth.
