Best Faucet Water Filter Reviews 2020 (UPDATED)

1. Brita on Tap Faucet Water Filter System


  • Trouble-Free Installation And No Tool Required
  • Filters Out 99% Lead, Chlorine For Taste/Odor, Asbestos And Benzene And Other Tap Water Contaminants
  • Can Furnish Up To 100 Gallons Of Water
  • Filter Life Indicator Technology

Filtration Technology: 

User-Friendly With An On And Off Switch Filter

Additional Features:

3 Spray Functions: Filtered Water, Unfiltered Water, And Unfiltered Spray

What We Like

Brita is another faucet water filter I know I can trust, making them a top choice for water filtration. Their filter handles 60 types of contaminants, including lead, chlorine, and asbestos, among other nasties. It takes out 99 of lead, which is a highlight. An additional filtration layer traps sediment and other small stuff.

What We Don’t Like

We get that the white design is kind of a trademark for Brita, but it clashes with most kitchen designs. Also, you’ll only get about 100 gallons out of each filter.

Plus, Brita is another manufacturer that uses a handy LED light to notify you when it’s time to change the filter. When things are going fine, it shows a green light to indicate all is well.

But the perfect part:

Brita’s water filter for sink faucet has three spray options. You have filtered water, unfiltered water, and unfiltered spray, which gives you back some of the function of the standard tap. With any setting, the water pressure is excellent.

What We Think

Brita is often a fan favorite for water filtration, and for good reason. It comes with handy features we all want—multiple spray options—and the focus is on convenience and saving money. Healthy water and convenience feel equally balanced with Brita.

2. Engdenton Faucet Water Filter Stainless Steel


  • High-Quality Food Grade Stainless Steel Housing
  • Fast Water Flow Of 0.5 GPM
  • Easy Installation And Tool-Free Attachment
  • Reduces Chlorine And Odors

Filtration Technology: 

Activated Carbon Fiber (ACF)

Notable Features:

10 times filtration ability

What We Like

Nothing will crack or leach on Engdenton’s stainless steel filter—it’s made of food-grade steel and hardy. Another benefit of the construction is the swivel head—you can even drink from the faucet like a fountain if you want to.

Water pressure is optimal, too, regardless of which adapter you use—they are also included.

Nearly eight cups per minute flow through this filter—no waiting around for a drink (or pitcher-full). You do need to change the filter about every six months—or every 320 gallons of water—which isn’t bad. Plus, replacement filters are washable if that’s your jam (it’s definitely more economical).

What We Don’t Like

Engdenton’s faucet mounted water filter won’t work with every type of faucet. If yours is a pull-down or other unconventional type, it isn’t compatible with your sink.

Also, the included rubber seal needs to be in properly to avoid any leaks. Not a huge concern overall, but it can fail or get tweaked, causing leaks.

What We Think

Engdenton’s water filter is a heavy-duty feeling faucet filter you can depend on—no breakage or cracks here. Its fast flow lets you fill bottles, cooking pots, and all manner of pans without standing in front of the sink forever.

3. PUR Advanced Faucet Water Filter


  • Minimizes Chlorine For Better Tasting Drinking Water
  • Hassle And Tool-Free Installation
  • Guaranteed To Eliminate Over 70 Contaminants (92% Of Pesticides, 96% Of Mercury,And 99% Of Lead)
  • 2 Year Limited Warranty

Filtration Technology: 

MAXION Filter Technology

Notable Features:

With Filter Life Indicator

What We Like

PUR has a great reputation for a reason. If design is your jam, you’ll love the look of this sleek faucet filter. There’s even an LED light to alert you when it’s time to change the filter—just lift the cover off to swap them out.

And it gets even better

PUR’s 3-stage filter is certified to cut down on over 70 contaminants, including up to 99 percent of lead. 92 percent of certain pesticides and 96 percent of mercury are also banished with PUR.

A simple on-off lever gives you access to tap water when you want it, and putting the filter on is marvelously simple: remove your aerator and washer, then click the filter on.

What We Don’t Like

This faucet water filters only last for 100 gallons of water—that’s around two to three months of use. Not ideal in terms of longevity, but passable. Another drawback is some slow flow problems, which seem to vary depending on the length of use and type of faucet.

What We Think

PUR has a great reputation, responsive customer service, and their filters come with CERTIFICATION that guarantees you’re getting cleaner water. Basically, the product eliminates the guesswork that comes with figuring out how clean your water is. The LED indicator light is super handy, too—who marks their filter change date on the calendar?

4. Culligan FM-25 Faucet Mount Filter


  • Easy-To-Install
  • Flow Rate Of 0.5 GPM At 60 PSI
  • Certified By NSF International
  • Filters Chlorine, Lead And Other Contaminants To Improve Taste
  • 2 Year Warranty

Filtration Technology: 

Advanced Filter Faucet Mount

Additional Features:

Filtration Method:Carbon Block

What We Like

Culligan faucet water filter is streamlined in a minimal style, so it doesn’t look too out of place. Each filter lasts for around 200 gallons, which is decent enough. There aren’t many frills, but it doesn’t need them at this level.

Level three filtration focuses on getting bad tastes and smells out, and this the Culligan does well. There’s also a long list of other stuff that the filter gets out, including sediment, lead, and other gross microscopic things. Culligan has also been independently certified by the Public Health and Safety Organization.

What We Don’t Like

The “diverter tab” to switch to tap water is small and tough to operate with sudsy hands. Also, the unit is chrome-plated, which isn’t as durable or highly-ranked as stainless steel. Slow flow is another commonly cited problem, so you may have to be patient with this one.

What We Think

You can see the difference in your water with the Culligan faucet water filter—it does an excellent job of cleaning up smells, aftertastes, and weird colors. If that’s not enough, their certification documents prove how well the filter cleans up the water. The slow flow can be frustrating at times, but at 200 gallons per filter, it’s hard not to love this economical option.

5. DuPont Faucet Water Filter


  • Improves The Taste, Odor And Clarity Of Your Water
  • Easy Affix To Standard Faucets
  • Filters Sediment, Chlorine, Cysts, Linden, Benzene, Asbestos, Mercury And Lead
  • 3 Year - Warranty

Filtration Technology: 

Micro Ban Antimicrobial Product Protection

Additional Features:

High Performance Water Filter System And Improved Water Taste In One Convenient Filter

What We Like

Micro ban antimicrobial product is built-in on DuPont’s unit, meaning you won’t find gross stuff growing in, on, or around your faucet. And the filtering is top-notch, too.

You’ll notice clearer water, less public-water flavor and odor, and cut down on particles and residue in your glass. No word on specific filtration levels or certifications here, but what comes out of the faucet is proof enough.

Overall, if flavor and clarity are your top concerns, DuPont addresses them well in an economic package.

What We Don’t Like

A low capacity—only 100 gallons—isn’t that impressive in comparison with other options. Looks aren’t a highlight either, with a combination of chrome and plastic components clashing a bit.

What We Think

If you’ve ever had mildew growth in your shower or sink, you know how gross and hard to clean it is. I really appreciate the addition of the micro ban product on DuPont’s filter—it keeps you from having to scrub and disinfect your entire faucet. The fact that the looks aren’t that spiffy is alright by me—chrome is chrome. And the relatively low filter lifespan is an okay tradeoff for this tough little faucet filter.

6. KINGRUNNING Faucet Water Filter with Activated Carbon


  • Hassle And Tool-Free Installation  
  • Clears Out Contaminants Such As Rust, Colloid, Red Worm, And Sand
  • Impressively Adsorb Residual Chlorine And Odor In Water
  • Eliminates Heavy Metal Ions From Water As Well As Block Mineral Scaling

Filtration Technology: 

7-Fold Filtration

Additional Features:

Used Ceramic Membrane And Activated Carbon As Filter Material

What We Like

In the same white style as Brita faucet water filter, KINGRUNNING chooses utility over style. But their clear cap means you can SEE when the filter requires changing—gross, right? You can reuse the filter; just rinse and replace. 

Ceramic membranes and activated carbon filter 20+ harmful metals and chemicals out before they reach your cup. A quick switch gives you access to tap water when you want it, too.

The seven filtration layers feature cool and effective measures like CaSO3, mineralized balls, tourmaline, cotton, and a filter net. But even with all these layers, water pressure is still excellent—on both the filtered and unfiltered sides.

What We Don’t Like

The plastic adapters are not a highlight with KINGRUNNING—most other brands use metal adapters that seem sturdier. No word on the specific number of gallons per filter, but the manufacturer estimates about three to six months of service life.

What We Think

While it’s gross to see your filter turn brown, the clear viewing window is handy for seeing when it’s time to change it. And while the plastic components feel a bit cheap, the performance speaks for itself with KINGRUNNING’s filter. Fingers crossed that you get the full six months of service per filter because that would be amazing!

7. RuiLing 304 Stainless Steel Housing for Hard Water


  • Simple Installation And No Tool Required
  • Made Of 304 Stainless Steel Which Ensures Crack And Leak Free
  • 90-Day Money Back And 1-Year Limited Warranty
  • Dual Connection Faucet Water Filtration System

Filtration Technology: 

Activated Carbon Fiber (ACF)

Additional Features:

7-Layer Recyclable Filtration 

What We Like

RuiLing faucet water filter is durable, made of stainless steel like many other filters. The highlight with this system is the multi-layer filtration system. In this filter you’ll find:

  • A ceramic layer for nixing salmonella, MRSA, and more
  • Calcium sulfite for sloughing off chloroform, bleach, rust, and carcinogens
  • A layer for backing off microbial bugs
  • A stone section for further bacteria prevention
  • Activated carbon for absorbing odors, chlorine, and other impurities
  • A cotton exit area to grab solids and bacteria

Beyond the filter itself, the multi-mode faucet is handy; you can switch from filtered to tap water in a snap. And even if you have a somewhat nonstandard faucet, this filter may still fit.

Another perk is the ability to reuse the filter—you just sand it, then replace.

What We Don’t Like

A handful of faucets aren’t compatible, but you need to check the product images to see if yours will work. Also, follow the instructions thoroughly when installing or it might leak.

Some customers don’t like the aesthetics of the adapter. Of course, that’s a personal preference—you may not mind its looks.

What We Think

Being able to swap between tap water and filtered is helpful for washing dishes and other household tasks. For environmental friendliness, the reusable filter earns high marks, too.

Final Verdict

Brita Faucet Filter System

In my opinion, by far the most amazing water filter for sink faucet is the Brita Filter System. It’s durable and its filters last longer than comparable options. It removes 99% of lead and reduces chlorine and asbestos. 

If you’ve been researching filters for ages, you can stop here.

Because in general, water filtration focuses on:

  • Long-use filters—three months or more—are ideal.
  • Rugged construction to withstand daily use (and abuse).
  • Accessibility—getting the water you need, the way you want it.
  • Speed—high water pressure and quick refilling for cups, bottles, and more.

If you want cleaner, fresher water without harmful contaminants, this checks all the boxes, and then some.

How to Pick the Perfect One for Your Needs?

When you choose the best faucet mount water filter system, you know you want cleaner and less, um, flavorful water. But apart from that, you might wonder:

How to Choose the Unit

In short, it depends on what you need. Do you want the ability to filter hot tap water? Are you looking for filters that don’t require changing often? Is style a priority?

Think about what would make your filter more convenient and suitable for your lifestyle. For example, if you know you and your family (plus fur babies) drink a ton of water daily, you might look for filters with longer lifespans.

In contrast, if you rarely fill a water bottle from the tap but want cleaner water for coffee and tea, your priority may be a higher-temperature filter. Longevity might not be a concern, as you don’t drink gallons of water daily.

System Features

Sure, each water filter removes contaminants and bacteria from your drinking water. But what other features should you look for? We’ll break them down here.

  • The option to switch to tap water. You don’t always want to use filtered water for, say, washing dishes.
  • Reusable or washable filters. Being able to scrub/sand/rinse a filter and replace it is super economical and handy.
  • 360-degree (or similar) function. If you prefer shower-head style sinks, you’ll like the spinning function of these rotating filter options.
  • Certification. Many faucet filters offer certification from independent agencies—confirming that they actually do what they say.
  • Durable construction. As a rule, stainless steel filters tend to be more rugged than chrome-plated or plastic filters.
  • Replacement alert lights/visibility. Knowing when to change your filter can be tricky. Some filtration devices have LED lights that alert you when it’s time. Others offer a clear viewing window so you can visually inspect your filter before removing it.
  • Temperature limitations. Many filters have maximum temperature limits to avoid damage to the unit. If you like to use hot filtered tap water for tea, French press coffee, or other uses, make sure to choose a filter that can handle high temps.

Removal of Dangerous Substances

I’ve read a lot of scary things about dangerous substances in our water.

For example, too much fluoride (even relatively small doses) can cause musculoskeletal disorders and other health problems. Plus, we already know lead isn’t healthy for anyone.

The good news?

Faucet water filters get rid of this stuff.

Your filter can:

  • Filter lead and fluoride out of your drinking water.
  • Get rid of chlorine—which can give your water a chemical-y aftertaste—and other gross flavors.
  • Reduce pesticide levels.
  • Remove arsenic.
  • Suck out volatile organic compounds (VOCs) that you don’t want to be drinking.
  • Eliminate sediment—i.e. dirt and other organic stuff, plus corrosion residue from your pipes.

Considerations Before You Buy

For a kitchen faucet water filter built into your sink, you can’t go wrong with a screw-on option.

But there’s a lot to think about before buying a filtration system. Different filter types, filtration methods, and styles can impact your buying decision.

According to the Environmental Working Group (EWG), activated carbon is one effective way to get the gunk out of your drinking water. Other common filtration methods include:

  • Cotton
  • Ceramic
  • Net material
  • Minerals

If you know your neighborhood’s city water has certain common contaminants in it, you may want a targeted filter for specific bacteria or metals. Or, in contrast, if your city adds fluoride to the water, but you want to avoid it, filtration that focuses on fluoride removal—and perhaps that alone—would suit your needs best.

How to Install Water Filter Faucet

Figuring out how to connect your water filter faucet attachment might be the hardest thing about water filtration. The good news is, it’s not that tough. You may not even need tools to handle the task—most manufacturers say their installs are tool-free.

To install your filter:

  1. Remove the existing spray nozzle (AKA, the “aerator”).
  2. Grab an adapter, if necessary. Most kits come with a handful of them for various installation applications.
  3. Apply plumber’s tape, as necessary, to the threads of the faucet. Some kits don’t include this, nor do they require it.
  4. Screw the adapter onto the faucet threads.
  5. Insert the filter into the adapter.

That’s it!

Similarly, to remove a faucet filter:

  1. Remove the filter portion.
  2. Unscrew the adapter, as applicable.
  3. Remove/reapply plumber’s tape as necessary.
  4. Put your aerator/nozzle back on.

Procedures vary for filter replacement, but most commonly, you’ll remove a top cover, then slip the filter loose. Some brands allow you to rinse, wash, or sand the filter and then reuse it.
