02 The Runner Up

Pur Faucet Mount Water Filtration System

PUR FM2500V Classic Faucet Mount Filter

  • Reduces Chlorine
  • Water filter life indicator
  • Tool-free attachment

Representing a slightly more affordable but just as capable entry into PUR’s range of hardworking water filters, the PUR Classic Faucet Mount Filter gets the job done for half of the price of most of its filter competitors. Featuring the smallest, most compact, yet hardest-working filter we’ve ever seen, it gets the job done in half the time we’ve seen it take other faucet mount models to filter you water.

One thing that sets this model apart from other faucet water filters is the LED light on the side which lets you know at a single glance what the status of the water filter is. No more guessing, no more cryptic marks on your calendar that you’ll forget before it’s time, no more tasting metallic water and realizing that you should have changed your filter weeks ago!

The filters that come with this piece of equipment last for 2-3 months, on average, which is fantastic: you’ll only have to buy replacements quarterly, instead of monthly (like some brands require you to do)!

The beautiful dark grey color of this faucet mount filter is an excellent complement to any kind of aesthetic you may have in your kitchen. The fact that it likely won’t match your existing kitchen water faucet exactly is a distinct choice that the PUR corporation made! By making it clear where your existing kitchen faucet ends and your water filter begins, PUR helps you make the replacement and installation process even easier.

04 Best For Removing Chlorine

Waterdrop WD-FC-02 ultra filtration water faucet filtration system

Waterdrop Filtration System

  • 320 gallons of refreshing water
  • 0.5 gpm steady flow
  • Ranges from 0.01 micron to 0.1 micron

Waterdrop, another relatively new name in water filtration systems, brings several fantastic features in their flagship product: the 320-Gallon Ultra Filtration System. As its name implies, this faucet water filter can go through 320 gallons before having to be changed—which, for the average user, will last most of one full year.

The longevity this represents is staggering. You’d think that with the amount of savings this faucet mount filter would net you in unnecessary filter replacements you’d be expected to pay much more for this product! However, this isn’t the case. This incredibly long-lasting filter is yours for the same price as many of its shorter-wear competitors.

This faucet mount filter was the very first to innovate and practically use the UltraFiltration system, a system of filtering water which measures its pore size in microns—which are magnitudes smaller than the pore sizes of similarly priced models. This water filter system gets rid of 99% of the chlorine in water, is ten times more absorptive than usual carbon filters, and gives you water that isn’t just clean and tasty—it’s downright silky.

Thanks to its steady 0.5 GPM flow rate, stutters and uneven flows are a thing of the past. With the Waterdrop Ultra Filtration System, it’ll be just like using your regular kitchen faucet—only much, much better.

In summary, this is a great faucet water filter if you're looking for quality, long life, and good value for money.

05 Best Budget

instapure f2 essentials tap water filtration system


  • Chrome Base with clear cap
  • No tools necessary for installation
  • Reduces bad taste and odor from chlorine

The Instapure system provides a simple way to switch between filtered and unfiltered water - not a thing that most other filters do, assuming (as they do) that once you get filtered water, you won’t want to go back. However, that isn’t always the case! There are some projects for which unfiltered water will suffice.

Being able to go back and forth between filtered and unfiltered water gives you an important advantage: You’ll be able to extend the life of your water filter by a lot! Therefore, the simple switch that the Instapure F2 Essentials Faucet Water Filter includes is a huge plus for longevity: a sign that the company behind this faucet mount water filter is caring about you, and not simply its bottom line.

This filter is certified ANSI/NSF for the complete and effective removal of chlorine from your tap water, which will not only make it a lot safer but also make it taste a lot better: definitely a win-win for you and your household.

The faucet mount filter features a sturdy chrome base which has a clear cap atop it, exposing an easy view of the filter itself so you can tell at a glance if it’s time to change ıt. The engineers who designed this product were clearly thinking of customer experience when they designed it—and it really shows.

06 DuPont Faucet Filter

instapure f2 essentials tap water filtration system

DuPont Faucet Water Filter WFFM100XCH

  • 100 Gallon Filter Capacity
  • Flow Rate 0.5 GPM
  • Chrome Color

The Dupont Premier Faucet Mount Drinking Water Filter offers a high performance way to get better tasting, safer water. Often, you’ll be required to use several different filters to get safer and tastier water: not with this model. Dupont designed this water faucet filter with convenience in mind.

The technology that has gone into this water filter is of the highest quality and provides supreme value. This is a water filter that can get rid of all the sediment, chlorine, cysts, linden, benzene, asbestos, mercury and lead that existed in your water. None of that is good for you, so it’s a great investment in your health as well as you’re family’s to get that taken care of!

The unique thing about this faucet water filter is the micro ban antimicrobial protection it naturally comes with. Because your faucet water filter will be coming into contact with less than hygienic materials (that’s the whole point!), even the best water filters often don’t have a great shelf life. This protection will make sure that this investment sticks around to protect you for a long time.

Another bonus: This faucet mount water filter features a universal spigot attachment, which means that it's easy to install the unit on any water faucet in your home. No finicky installation required: just plug in, and you and your family will instantly have cleaner drinking water.

07 Culligan Faucet Filter

culligan fm-25 faucet mount filter

Culligan FM-25 Faucet Mount Filter

  • Chrome Finish
  • 0.5 gpm flow rate at 60 psi
  • Temperature Range: 40-100 degrees fahrenheit

With a brushed chrome finish which makes this mounted water filter look the most sophisticated of the bunch, the Culligan Faucet Mount Filter is efficient and inexpensive—a true bargain. This is one of the smallest faucet water filters we’ve seen; it blends into your kitchen in a way that several of the other filters will never be able to do.

It also works well with your faucet! Boasting a flow rate of 0.5 gallons per minute and 60 psi, if you use this water filter you won’t feel like your water’s coming out at merely a trickle. This filters out most of the substrates that we know are polluting the average tap water system, including atrazine — a chemical barred by few other filters.

This brand also includes a few filters in the price, which is thoughtful; you won’t have to buy another faucet filter for possibly a full year! This filter system has been vetted and tested by the NSF, and can work with pressures between 30-100 psi and temperatures between 40-100 degrees Fahrenheit.

A unique feature of this faucet filter is simply that the Culligan team includes several different adapters with your purchase so that you’re sure that this water filter will fit on any faucet in your home. It’s thoughtful touches like these that set this brand apart!

Faucet Water Filter Buying Guide

tomatos and kitchen faucet

Now that we’ve introduced the cream of the crop in faucet mount filters, let’s talk about some of the ways you can make the crucial decision: which is the best faucet filter for you?

We all want clean and tasty drinking water—it’s clear why you’d need a water filter. But how do faucet filters work? Read on as we tackle that question next.

Faucet Mount Filter Style

Going eco-friendly and healthy doesn’t have to be an unfashionable thing! Each of the faucet water filters we reviewed has a specific style and look. When looking at style, consider what kind of aesthetic you’re going for in your kitchen.

Do you need colors or finishes to match? Do you prefer smooth, unbuckled surfaces, or do you like it when there are a lot of moving parts? If there’s an LED light, does it matter to you that it might flash bright green or bright red? These are all things you need to think about when you’re looking for the best faucet water filter to add to your kitchen.

Cost and Warranty

A faucet water filter is like any home improvement: basically an investment in your home, for which you definitely need to balance cost and value. 

One thing that may help you justify looking at higher-priced faucet water filters is if the model comes with a good warranty. A warranty may feature a price-back or replacement parts guarantee if you don’t like or use the product, or if the water filter breaks within a set amount of time after you purchase it.

You might also want to consider under sink water filter if you think that faucet water filter might not be right for you.

How to Install a Faucet Water Filter

Now that we’ve discussed reasons to buy a water filter and the different factors that might go into your decision as to which water filter to purchase, let’s end by talking a little bit about how to install the faucet water filter you just purchased! After all, the story only ends happily if you’re able to use it as soon as you are able.

1. Turn off the Water Supply

To avoid any painful or embarrassing water spouts which could arise as a direct result of your tampering with your water system, it’s a good idea to start any plumbing project (no matter how minor) by turning off your water supply. It’s a quick step which has enormous results; don’t discount the positive mental effects of being clean and dry!

2. Remove The Faucet´s Aerator

Most faucets come equipped with a built-in aerator, a tiny device at the very end of your water faucet which helps add a bit of air to your water flow (which is why water comes spurting out of most faucets instead of merely flowing quietly). You’ll need to remove this in order to attach your faucet water filter to the faucet.

3. Clean the Buildup

This part may be a little gross, but it should also be motivating in that what you’re removing from your faucet now is exactly what you’ll be removing from your water via the faucet filter you’re about to install! Get some hot water and a clean towel, and make sure to get the gunk all out of there.

4. Check if You Need an Adapter

While the manufacturers of faucet water filters have tried to make their filters as universal as possible, sometimes an adapter unit will be required. Some of the products we’ve linked above include these adapters—but it’s always a good idea to check the make of your sink and faucet against the shape of the faucet water filter, just to make sure that you won’t be frustrated by a bad fit once you have the product at home.

5. Attach the Faucet Water Filter

This part speaks for itself! Click the water filter on to your faucet.

6. Flush the Filter Cartridge

You’ll want to fully saturate the water filter for about a minute before drinking any of the water that comes out, just to make sure it works properly!

Faucet Water Filter Cleaning and Replacement

As far as ongoing maintenance goes, most makers of faucet water filters have tried to keep it as simple as possible (which is good for you!). Wipe down the water filter whenever you clean your kitchen, and make sure to remember how often to change the water filter—whether that be by a note on your calendar or an LED sensor on the device itself.
