Look, you already have a water faucet in your kitchen. Why not level up and install a faucet filter directly to your tap? If you’re looking for a product with an affordable price point, and basic assembly without any plumbing alterations than a faucet filter can be a great buy.

Faucet water filters are an ideal option to change your regular tap water into filtered, and great-tasting water. They’re a great middle-ground between regular water filter pitchers and under-sink filters. Pitchers have a limited ceiling for performance based on their lack of capacity and under-sink water filters that require alterations to your plumbing but have superior filtering capabilities.

We’ve narrowed down some important factors when it comes to choosing a faucet filter for consumers, both novice and experienced. Different consumers will all be looking for different characteristics, so we’ve covered a wide range of aspects to ensure you can pick the right faucet water filter for your home. 

Here are the considerations in choosing a faucet water filter,  and the products which made the cut in our list of best faucet water filters.

Contaminants removed

With the large amounts of harmful contaminants in U.S. drinking water sources, it is important to consider what a filter is capable of removing

Faucet filters have the ability to remove chlorine, and chlorine byproducts, taste, and odor issues, and can also remove harmful contaminants such as lead

Here are some of the main concerns in America’s municipal and well water supplies according to the WQA that faucet water filters have the potential to remove:

Contaminants Certification to remove Products
Harmful contaminants: Lead, Asbestos, Mercury, Cysts, VOCs etc.* NSF 53 PUR FM-3700, Brita 7540545, DuPont WFFM350XCH
Chlorine and Chloramines NSF 42 PUR FM-3700, Brita 7540545, DuPont WFFM350XCH
PFAs P473 N/A
Emerging contaminants NSF 401 PUR FM-3700

*Check with product performance data sheets if you are concerned about a particular contaminant.

We suggest you check your local Consumer Confidence Report (CCR) to find out what is in your water

The types of filters that faucet filters use are typically a combination of absorption (e.g., carbon) and ion exchange resins. Of the above contaminants, they have the ability to filter out lead if certified to NSF 53, and chlorine if NSF 42 certified. They also have the ability to filter our many more contaminants, read product descriptions for further information on specific contaminants. Faucet filters cannot filter PFAS, for this we recommend an under-sink model.

Faucet Filter certifications:

  • NSF 42: For mainly aesthetic issues such as chlorine, taste and odor, chloramine, particulate, iron, manganese, zinc and total dissolved solids (TDS).

  • NSF 53: For reducing or eliminating contaminants that have known negative health effects. NSF 53 products have a carbon filter and can reduce contaminants to various degrees depending on the quality of the filter. These contaminants include heavy metals (e.g., lead), Cryptosporidium, Giardia, pesticides, herbicides, benzene, MTBE, radon, trihalomethane, and PCBs.

  • NSF 401: For reducing 15 ‘new” contaminants that are not yet regulated by health or water quality agencies. These include contaminants such as pesticides, flame retardants, detergents, and pharmaceuticals.

Our best overall water filter is also the best faucet filter for lead removal. It is made by PUR, a brand that has valued keeping people’s water clean for the last 30 years. And, considering your goal is to have purer water, a company with a good reputation is important.

Pur FM-3700

  • Removes 70+ contaminants

  • Certified by NSF and WQA (NSF 42, 53)

  • Filter life of 100 gallons (or 3 months)

  • LED filter sensor

  • One-click installation

The nice thing about this product is that it comes in multiple prices depending on the finish you want. Chrome and stainless steel will run you close to $40, and the less expensive black plastic finish will cost $20. We recommend the metal models as they will provide more longevity, plastic products seem to have more issues with leaks.

Either way, PUR stands behind its products with a fabulous 2-year warranty.

The PUR FM-3700 is certified by the Water Quality Association (WQA) to NSF 42 and 53 to reduce over 70 contaminants. It reduces over 99% of lead and other harmful contaminants and over 97% of chlorine. 

It filters through a mixture of carbon and ion-exchange filtration. For exact contaminant removal, see the PUR FM-3700 performance data sheet, here are some of the main contaminants and percent removed:

  • Lead: >99.7%
  • Chlorine: 96%
  • Asbestos: >99%
  • Emerging compounds: >94.8%
  • VOCs: 99.3%

The filters on the FM-3700 will last for three months or 100 gallons, whichever comes first. 

To know when it’s time to change your filter, a modern LED indicator displays the filter status and will let users know when it’s time to swap out filters.

At just under $50, this product is worth every penny for it’s filtering capabilities. Filter replacements will cost $15, making it affordable. 

If you change the filters every three months, you’re looking at a cost of $60 to run your system per year. With a total five year cost including system purchase of approx. $315. The average price of a bottle of water is $1.45, so if you consumed a bottle of water every day for 5 years, it would cost you $2,646.25. Tap water costs 0.004 per gallon, which is 1/300th the cost of bottled water.

A nice additional feature is that this model has a 360-degree swivel making it great for all your dishwashing needs – look out big pots and pans!

Installing this filter is a breeze with one-click twist and lock installation, so you should have your new filtration system up and running in a matter of minutes. It also has a bypass valve for any moments you don’t want to filter any water and have a stronger flow.

Ideally, you should look for filters that have to be changed as seldom as possible. It may not seem like a hassle but if you have to change your faucet filter every month, it can become irritating. 

Filters with at least 100-gallon filtering capabilities should last about three months (depending on use) and some of the best long-lasting filters have 200 to 320-gallon filtering capabilities, which can last as long as six months. 

When we say depending on use this means if you are using filtered water from your kitchen faucet for purely drinking or for doing dishes/rinsing plates as well. 

All our faucet filters have the ability to switch between filtered and unfiltered water without removing the faucet attachment

If you are using your faucet filter for drinking water only then you can calculate this at about 0.5 a gallon per day (gpd) per person. So if you had a family of 3 you would consume 1.5 gpd, which is 45 gallons per month. If you are using filtered water to do your dishes in the sink then your consumption will go up, the average sink holds 9 gallons, so if you wash your dishes once a day that adds up to 270 gallons a month.  So you’d want to get a faucet filter with higher capacity.

We all live pretty busy lives and keeping track of your water filter’s lifespan doesn’t exactly take precedence over everything else. Faucet filters that have a ‘filter change sensor’ is a great way to notify you when the filters need changing

Unchanged filters can result in stale water, completely neutralizing the purpose of a faucet filter

Filter sensors will let users know a few days before the filter needs to be swapped out. Keeping track manually isn’t very conclusive to having an effective system and having an automatic reminder is very useful in the long run.

There are a couple of prices to consider when buying a water filter system: the unit’s price and the price of filters

For systems, you’ll want to spend at least $20 for an adequate faucet water filter. Higher-quality models will hover around the $30 to $60 range with premium options nearing the $50 mark. At this price point, you should get a faucet filter certified to NSF 42 and 53 with metal finishing. Cheaper models will generally have a plastic finish, which can be more prone to leaks

Filters typically range from $10 to $15 each, many of which are sold in packs of three, which is smart to ensure you always have some in stock so you don’t run out. We recommend purchasing a new three-pack every time you install your last filter. In essence, a filter system without the actual filters becomes rather useless.

  • Minimum working water pressure: 10 psi
  • Maximum working water pressure: 100 psi
  • Minimum water feed temperature: 34°F
  • Maximum water feed temperature: 100°F
  • Number of stages: 3
  • Fitting style: Push to connect

What Flow rate & water settings are right for you?

Flow rate is something important to many consumers, because who wants a slow running faucet? We’d recommend checking the manufacturer’s product description before purchasing as generally, filtered water that travels through faucet filters will be slightly slower than free-flowing water. 

A nice feature that many faucet filters have is different spray options that can vary the flow rate and filtration level. If you want to wash your dishes you may want a higher flow rate and less/zero filtration. If you want a glass of water then you’ll want a slightly slower rate and more filtration. 

It can be difficult to find the flow rate on some products but look for products with at least a minimum filtered flow rate of 0.5 gallons per minute (gpm)

The average flow rate of faucets is between 1 to 1.5 gallons per minute, so you’ll still be able to fill up a glass of water in a matter of seconds, but filling up your sink can take twice as long with filtered water. 

Most faucet water filters should be able to handle the temperature and water pressure of your home’s water.  The minimum water temperature of a faucet water filter should be 40-41°F or lower as this will cover even the coldest winter temperatures when tap water temperatures can drop to as low as 45°F. The majority of faucet filters will be able to filter water up to 100°F, anything over this and they are not graded to filter. However, we recommended to avoid using any faucet filter to filter hot water, as this increases the potential for damage. 

For water pressure faucet filters cover most typical houses water pressures. The average water pressure of a home is 50 psi, faucet filter minimum pressure requirements range from 10-35 psi.

Warranty

Having a lengthy warranty is a nice bonus when purchasing a faucet water filter. If your product is faulty then you won’t have to deal with a headache of finding a new one, and manufacturers will provide you with a replacement. 

With that said, consider purchasing products with at least a one year warranty, which is the average. If companies offer two or three-year warranties, it’s all the better. Generally, the longer warranty the manufacturer offers, the more confidence they have in their product.

Installation

Whereas some consumers will stray away from buying a filter because they’re scared of installation, faucet filters don’t have that problem. They’re very easy to install and can be set up, thanks to easy-to-follow instructions, in a matter of minutes

So, without further ado, here are some more of our favorite faucet filters on the market right now. 

Best value

NSF: 42, 53
Price: 22.97

When it comes to value, the $24 Brita Faucet Filter (7540545) is a great all-around choice.

Pros:

  • Very inexpensive

  • Impressive certifications

  • Efficient

  • Easy to install

  • Attaches directly to any standard faucet

Cons:

  • Does not fit pill out and spray faucets

  • Made out of plastic

  • Not very attractive (plain white)

The Brita brand is well respected when it comes to water products and it can reduce the following contaminants and more!):

  • Lead: >99.3%
  • Chlorine: 97.4%
  • Asbestos: >99%
  • Cysts: >99.99%
  • VOCs: 99.5%

It is certified to NSF 42 and 53 to reduce aesthetic and harmful contaminants. For exact contaminate removal check out it’s performance data sheet.

The Brita Faucet Filter attaches directly to any standard faucet and the installation requires zero tools and is very easy to install

For optimum performance, a green and red light flickers to let you know when the filter is working and it lets you know when it’s filters need to be replaced (on average every four months). 

These filters can provide up to 100 gallons of filtered tap water which is equivalent of replacing 750 16-ounce plastic water bottles. 

It also has three spray options: filtered water, unfiltered water, and unfiltered spray.

Aesthetically, the Brita Filter is made out of white plastic so it’s not very attractive compared to other chrome products. 

But, considering its price and efficiency, you can’t really go wrong. The Brita Filter comes with a one-year warranty and it has an impressive amount of user reviews online. 

  • Minimum working water pressure: 20 psi
  • Maximum working water pressure: 100 psi

Best for Chlorine/Filter life

The DuPont WFFM is revered for being great at removing lead from water. It has a Microban Antimicrobial product protection built-in to the cartridge housing and media for improved filter life and performance. It’s also tough to top this product’s warranty. 

The real standout for this product is it’s 200-gallon filter life. Trumping the vast majority of filter lives of faucet filter products. Some lesser models may have longer filter lifes, but they cannot remove the contaminants that the DuPont can.

Pros:

  • Great for lead removal

  • Beautiful chrome finish

  • Three year warranty

Cons:

  • Doesn’t filter fluoride or arsenic

  • Expensive filters

In terms of contaminant removal, the DuPont Premier Faucet Filter removes sediment, chlorine, cysts, linden, benzene, asbestos, mercury, and of course, lead. Here are some of the top contaminants it removes:

  • Lead: 99%
  • Chlorine: 99%
  • Asbestos: >99%
  • Turbidity: 97%
  • Cysts: 99.98%
  • VOCs: >95%

Performance data sheet

The DuPont faucet filter has NSF 42, 52, and 372 certifications to back up it’s filtering claims

At $24.10, it’s a very affordable product but its filters are pretty pricey at just under $20 ($19.96). 

Its flow rate is 0.5 gallons per minute, which is average for water faucet filters. It is designed for easy installation that can attach to most standard kitchen faucets

This system includes one premier faucet mount, one high protection and high capacity faucet mount filter, two faucet adapters, two washers and plumbing tape. Talk about a bundle, huh?

It’s three-year warranty is also very appealing as is its chrome exterior. But again, when it comes to lead removal, especially at a low price, you can’t go wrong with the DuPont WFFM100XCH Premier Faucet Mount Filter.

  • Minimum working water pressure: 10 psi
  • Maximum working water pressure:  100 psi

How do faucet water filters work?

Almost all faucet water filters remove contaminants from drinking water via adsorption. This refers to the ability of some materials to bind others to their surface upon contact. Among the best adsorptive materials around is activated charcoal, which you’ll find ground down and expertly structured inside the cartridge of your faucet filter.

When water from your tap and through the filter, organic, carbon-based contaminants in the supply make contact with activated charcoals large surface area and are adsorbed, reducing or removing a number of common pollutants. These include chlorine,

While the treatments applied by your local water supplier should remove potentially harmful materials like protozoa and viruses from the water source, this process can leave behind trace chemicals and sediments that worsen water taste and smell. Adding a faucet filter to finish off the filtering process leaves you with H2O that’s not only safe but fresh-tasting.

FAQs

In terms of filtering technology, there’s not too much difference between a pitcher filter and a faucet-mounted filter. Both mostly use activated carbon to remove organic compounds and improve the taste of water.

Aside from where they’re placed in your home, the main difference between these two common filter models is that faucet systems use water pressure to push water through the filter cartridge, rather than relying on gravity. This allows some faucet filters to claim slightly more filtering power than pitcher models.

Due to their design, many faucet filters are also able to incorporate larger filter cartridges that pitcher models, leading to a longer period between replacements—and another boost in efficiency!

Here’s an important question. There are certain faucets that are not compatible with faucet-mounted filters. In particular, faucets with pullout hoses and those with adjustable head settings may not accommodate the way that many filters screw onto the tap. The same goes for vintage or bespoke design faucets.

Most filters will come supplied with adapters that replace your faucet’s aerator (the very end of the faucet) and help thread the filter directly onto the tap. So, if your faucet has an unusual aerator, then you might struggle to find an appropriate adaptor.

Also, it’s worth considering the robustness of your sink system. Faucet filters and a small, albeit additional weight to your tap, so if you happen to have a very flimsy model, it may strain the fittings and make leaks more likely.

Depending on the hardness and purity of your source water, faucet-mounted filter cartridges generally filter around 100 gallons, which for most people, equates to about three months of use. Many filters will have their own advice on this, as well as indicators on the device to help you track usage over time.

Once that time is up, you’ll need to replace the filter cartridge. Because adsorption binds contaminants to the carbon’s surface, once that surface is filled, there won’t be any filtering occurring inside your device.

Faucet-mounted water filters are fast, convenient, and attractively priced filtering solutions. They fit straight onto your tap, meaning that purer water is there right when you need it. This helps encourage better habits and more daily water consumption—plus, the activated carbon used in filtering means no more chlorine aftertaste, offputting smells, or bitter flavors from sediments.

While not every tap can fit a faucet-mounted filter, standard kitchen fittings are normally compatible, and there is a range of different filter types and brands to choose from. To help decide what works best for you, here are the products which made the cut in our list of best faucet water filters<span style=”font-weight: 400;”>.

Choosing the best faucet water filter – It’s all about efficiency

I see you. You’re a thinking person. While others are running back and forth from their refrigerator, constantly filling and refilling their water pitcher filters, you’ve made the intelligent decision to remove all unnecessary effort from the filtering process, by installing a filter right where you need it—on the faucet itself.

Congratulations! It’s a smart choice. Faucet-mounted water filters are reliable, efficient devices that provide the same benefits as other types of kitchen water filter, without the need to move around your kitchen or wait for a reservoir to fill.

Efficiency is an important quality in any water filter. Because kitchen filtering solutions are designed to improve the taste and quality of your water, and not provide any water safety assurances, most people look to filters as a way of encouraging a healthy, more beneficial lifestyle. The easier and more convenient it is for you to access great-tasting water, the more likely you are to get your recommended intake on a daily basis.

It’s true that other kinds of filter systems—such as under-sink and point-of-entry filters—do away with any visible filter component at all, treating your water before it hits the tap. However, these solutions require installation, often with the assistance of a professional. This means extra time and possibly incurring labor costs. So, if you’re looking for a filter that you can start using straight from the box, a faucet system is a good way to go.
