What Is The Best Water Filter For Faucet

The Best Faucet-Mounted Water Filter

  • Who this is intended for
  • What we looked for and tried
  • Our choice is: Filtration System for the Pur Advanced Faucet The rivalry between the two teams

In addition to providing filtered water on demand, faucet-mounted water filters have the advantage of being a convenient alternative for families that use a lot of drinking water every day or for those who wish to cook or wash dishes with filtered water in addition to drinking it. As a result of the higher water pressure in the pipes, faucet-mount filters are more successful at removing pollutants than most pitcher filters, even our top selections in that category. Furthermore, the filters last longer than pitcher filters, often three months or 100 gallons as opposed to two months or 40 gallons with pitcher filters.

They cannot be fitted on faucets that have integral pull-out sprayers; they can only be installed on classic one-piece faucets.

Most filter installations feature a switch that allows you to switch between using the filter and using the standard tap.

  • If these disadvantages dissuade you from using a faucet-mounted filter, an under-sink filter may be a more suitable alternative.
  • Notably, neither faucet-mounted nor under-sink water filters dispense water as cold as you would obtain from a pitcher kept chilled in the refrigerator.
  • First and foremost, you may not require one.
  • The CCR lists every contaminant that has been tested for in your water supply, as well as the level of contamination found and whether or not that level meets Environmental Protection Agency standards.
  • Secondly, there should be no expectation that a single faucet, pitcher, or under-sink filter can provide a lasting solution to a chronic water problem such as increased lead levels.
  • Finally, water that tests clean in municipal pipes can still get polluted as it travels to and through your house, as was the case in Flint, Michigan, and Newark, New Jersey, respectively.
  • If you want to be absolutely certain about what is in the water that comes out of your faucets, we recommend investing in a home water testing kit.

ANSI/NSF certification indicates that a filter has been tested in an approved laboratory and has been determined to decrease a specified pollutant to levels below the EPA’s maximum allowable concentration for drinking water.

In order to be certified, they must still decrease the challenge-solution pollutant to a level that is below the EPA’s permissible standard.

There are just a few other ANSI/NSF-certified faucet filters available in North America, and none have anything like the number of certifications that this one has.

We brought in a model from each of the companies.

The Complete model, which we examined, allows you to control the water flow between three different settings.

Pur has two alternative housing options: a horizontally oriented housing (found on theBasic, Advanced, and Bluetooth Ultimate models) and a vertically oriented housing (found on the Basic, Advanced, and Bluetooth Ultimate models) (theClassic).

The Basic and the MineralClear are the two types of filters produced by Pur.

We put the Advanced model, which has a MineralClear filter, through its paces.

Once the filters were installed, we utilized them for many months, noting any positive and bad elements of each, ranging from their basic looks to their simplicity of installation to their dependability and durability, as well as any perceived influence on water quality and flavor.

When the findings of this method were combined with the filters’ ANSI/NSF certifications, the results revealed a clear winner.

Our pick

There are three different finishes available for the Pur Advanced model that we tested: polished chrome, brushed metallic gray, and a vibrant tropical blue dubbed seaglass. Each Advanced model is equipped with a MineralClear water filtration system. The otherwise identical Classic model is available in either black or white (and contains the Basic filter, which has the same ANSI/NSF certifications as the Standard filter). Our tester chose a chrome-finish Advanced because he liked the way it looked “almost deco,” but he was quick to point out that other finishes, such as the metallic gray version we photographed for this review, did not achieve the same result.

Despite the fact that our tester did not notice any difference, flavor enhancement is not as gimmicky as it may appear.

Flaws but not dealbreakers

It was determined by our tester that “the continual small pressure you apply to the filter’s valve in order to switch on the filtered water caused our faucet to start coming loose at its base on a few of occasions.” Another contributing aspect is that the beautiful chrome becomes filthy easily, so you’re always wiping it clean, which increases the amount of pressure on it.” he explained. When we saw it was happening, we just tightened the faucet base. I’m not sure if the same thing would happen with a better faucet, but it was a little irritation for us.

  • If the sink is shallow, for example, it may be difficult to get a glass beneath the spout if there is anything else in the sink basin.
  • Photograph courtesy of Michael Murtaugh We also put the Brita Complete Faucet Filtration System through its paces.
  • This also distinguishes it from Pur’s filters, which do not have the spray feature.
  • Pur’s faucet filters have a substantially higher number of ANSI/NSF certifications than the competition.
  • We discovered that the Brita dripped excessively throughout our testing, which resulted in a pink coating on the filter housing, which we believe to be caused by the bacterium Serratia marcescens, which is commonly found in moist sinks and showers.
  • Contrary to what the title on the Amazon product website says, the Waterdrop WD-FC-01 is only ANSI/NSF certified for chlorine reduction, as well as for taste and odor.
  • The same is true for the WD-FC-03 and WD-FC-06, which are quite similar but are made of stainless steel.

In addition, the Dupont’sWFFM100XCHandWFFM350XCHuse the same filter cartridge and are only certified for eight ANSI/NSF contaminants: chlorine, particle Class I, asbestos, lead, mercury, volatile organic compounds, cysts, and turbidity.

The Best Faucet Water Purifiers for Cleaner, Better Tasting Tap Water

What to Look for When Buying a Water Filter

Marshall Bright contributed to this article.

According to Rick Andrew of NSF International, a health and safety standards testing business that certifies water filtration systems, there are two primary reasons to install a water filtration system: first, it is environmentally friendly. Water filters for drinking water in the United States are more likely to be used to enhance flavor or remove hard minerals and protect pipes, as hard water (i.e., water with a high mineral content) can cause buildup in pipes and water fixtures and eventually lead to pipe failure.

If you have well water, ancient pipes, or live in a region where drinking water is dangerous, you may require a water filter to remove pollutants such as lead or real particles such as sand from your drinking water.

Even though your municipal water is clean, it is possible that you have aging pipes that are allowing toxins to leak into your water.

Filters that are approved to eliminate chlorine, for example, can also help to promote hydration by making water more pleasant to drink.

Independent Certifications

In part because good filtration is so vital (and because it’s so difficult to detect whether or not it’s functioning), certification is one of the few ways to be absolutely certain that your water filter is actually eliminating the impurities it promises to be removing on its box. The National Sanitation Foundation (NSF) is one such certification authority. Others to check for include certificates from the American National Standards Institute (ANSI) and the Water Quality Association (WQA) (WQA).

For example, the National Sanitation Foundation (NSF) gives certification for eliminating a certain quantity of chlorine as well as a separate certification for removing lead.

Andrew advises that you should double-check to make sure it is genuinely certified before proceeding.

Some water filters were featured in an earlier edition of our list that were deleted because they used identical phrasing that made it unclear whether or not they had been independently evaluated.


When selecting a water filter, you should also take into account how much water your household consumes. Although a small pitcher may do for a dorm or an apartment, bigger homes (or those who wish to filter water for cooking as well as drinking) may benefit from faucet or under-sink filters, which are less expensive and more convenient.

Although refilling a pitcher does not take much time, if you have to do it multiple times a day, it might be tempting to give up on it and simply return to drinking unfiltered water from the tap instead.

Replacement Filters

Another factor to consider is the cost of the filter. In order to get the most out of your water filtration system, consider all of the factors that influence its performance, including pricing, availability, and the frequency with which filters must be replaced before making your selection.


Water filtration systems can range in price from thousands of dollars to, in the case of a tiny pitcher, less than twenty dollars. Water filters for home use are available at a reasonable price and do not require a large investment; nevertheless, search for certifications. When determining how much money you want to spend, keep in mind the cost of the water filter as well as how often it will need to be serviced.

Types of Water Filters

A pitcher is the first thing that comes to mind when we think of water filters, however water filters may be utilized at practically every step of the water’s path through your home.

Whole-Home Systems

Whole-house water filtration systems filter all of the water that enters your home. “The most typical type,” explains Andrew, “is a water softener, which will assist in the removal of minerals and the’softening’ of your water.” Because hard water is detrimental to pipes and water fixtures, a whole-house filtration system is the most practical solution. Due to the fact that this sort of system filters water for the entire house, it is sometimes expensive and time-consuming to put in place.


The usage of a point-of-use filter is another alternative if you want to filter your drinking water for toxins or a particular flavor. These might be sink-mounted filters, or they can be located beneath the sink where you obtain your drinking water. If you don’t have well water, Andrew says whole-house filtration is usually primarily used for softening the water, and point-of-use systems are fine if you’re solely concerned with eliminating toxins. Compared to whole-home systems, under-sink filters are frequently less difficult to install; nevertheless, they are more costly than faucet attachments or pitchers.

Faucet Attachments

In the same way as under-sink filters do, faucet attachments provide immediate access to filtered water at a location where you would normally acquire drinking water, such as the kitchen sink. This type of filter may be fitted to the majority of regular sinks; however, it will not function with more unusual sink configurations, such as a pull-down faucet with a spray nozzle. A faucet attachment will often allow you to filter only the water you wish to drink while allowing unfiltered water to get through for things like dishwashing and other household chores.

This sort of technology also puts less strain on the filter because it only filters the water that is actually required.


The fact that pitchers must be replenished means that they do not provide the convenience of sink filters. However, according to Andrew: “some people like pitchers since they enable you to cool filtered water, which can make it more delightful to drink.” It’s also the most straightforward to set up. Furthermore, if you are merely filtering water for flavor, you may find a faucet filter to be cumbersome and unneeded while doing tasks such as washing dishes or washing your hands at the kitchen sink.

Another matter of personal taste here, and both faucet attachments and pitchers are capable of filtering out pollutants from drinking water.


Countertop water filtration systems function in a similar way to faucet filters in that they redirect water from the sink into a filtration system with its own water tap. Other countertop filtration devices, which function similarly to water coolers, must be refilled on a regular basis; they are often bigger than pitchers, but require less frequent refilling. You may install filtered water wherever in your home, even if it is far away from a water supply, which is an advantage of using these systems.


Water bottles may also filter water, allowing them to be recognized by the National Sanitation Foundation and the American National Standards Institute. As you fill your water bottle or drink from it, they may filter the water for you. Water bottles may be a terrific option if you want to drink filtered water while on the go, and they’re a great alternative to purchasing water bottles in the first place! Many home water filtration brands and filters, on the other hand, are intended to remove toxins from already treated water sources.

Despite the fact that filters of all kinds may perform an excellent job of eliminating impurities, Andrew believes that “no filter can really eliminate all contaminants.” Any filter that claims to be able to remove all or 100 percent of pollutants is deceiving the public, and no certifying authority would stand behind such a claim in good faith.


Nowadays, the phrase “Brita pitcher” is mostly used to refer to a water pitcher that has been filtered. Every one of Brita’s filters has received NSF certification, and its pitchers are well-known for their simplicity of use—just drop a filter into the pitcher and you’re ready to go. Brita also sells a variety of pitchers and filtration systems, such as faucet filters and water bottles, in addition to drinking glasses. Brita, on the other hand, does not provide under-sink or whole-home filtering systems, and not all Brita filters are equal.


Pur and Brita provide products that are fairly similar to one another: simple filters that remove impurities that affect taste as well as mercury and other toxins, and more costly filters that can remove lead as well as a larger percentage of contaminants and are thus more expensive. Pur does, however, provide the most number of certifications in both its basic and more costly filters.


In addition to countertop filtration devices, APEC now provides a whole-house filtration solution for customers.

These systems are meant to eliminate odors and chlorine, as well as minerals that can cause scaling on appliances, from a home’s water supply.


There is no such thing as a one-time purchase for water filtration systems, regardless of their size or kind. Filters are not indestructible; they will ultimately cease to be effective in filtering water. “This has the potential to have two consequences,” Andrew explains. The water may begin to flow more slowly through the filter itself as a result of these changes. More dangerously, the filter may eventually cease to be effective in filtering water, allowing pollutants to remain in the solution.

The National Sanitation Foundation (NSF) certifies filters to verify that they can continue to remove impurities for the duration of their specified lifespan, and even for a small amount of additional time at the end.

“However, at some time, it will just cease to function.” It is just as vital to replace your water filter according to the manufacturer’s recommendations as it is to choose the appropriate filtration system in the first place.


A variety of accessories and add-ons have emerged as firms attempt to differentiate themselves in the filtration industry, including Bluetooth capabilities and sensors to monitor filter efficacy. While these might be visually pleasing bells and whistles, they are not absolutely required. In other cases, such as when replacing filters, the sensor is not required if you follow manufacturer directions. In the end, what counts is whether or not the filter itself is capable of eliminating the contaminants that you desire to be eliminated.

Water filtration systems come in a variety of shapes and sizes, and none of them are necessarily better (or worse) at filtering out toxins than another. Based on how it was produced and approved, the same types of filters may remove a wide range of impurities. In order to avoid this, Rick Andrew suggests that you identify the kind of pollutants that you want to be eliminated rather than merely seeking for a filter that eliminates a large number of contaminants. If you are unaware of what is in your local water, you may obtain a water report to determine what is present.

Do water filters remove bacteria?

Despite the fact that the National Sanitation Foundation certifies filters that eliminate germs under a standard called P231,” Andrew explains that they are often built for activities such as camping, where you may need to drink water from a stream. If you have special worries about bacteria in your drinking water, make sure to get a filter system that has been certified specifically for bacteria removal.

Can you filter any type of water?

In a nutshell, certainly. Water filters may be utilized with both city and well water, as well as with both soft and hard (high mineral content) water.

Simply be conscious of what it is that you are attempting to eliminate. A whole-house system meant to remove minerals from hard water, for example, will not function the same way as a pitcher designed to remove chlorine for flavor.

Do water filters remove fluoride?

Yes, there are some who do. If you have a preference, make sure to double-check the certification of your filter.

How long do water filters last?

Water filtration systems are only as effective as the filters that are included within them. Every filter is intended to be changed, and all certifications are performed with the filter’s long-term performance as a consideration. If your filter has to be updated every six months, NSF will test each filter to guarantee that it has a six-month life span before it is placed in service. The filtration system itself can endure for several years if the filters are updated on a regular basis.

Countertop & Faucet Water Filter Reviews and Comparisons

Drinking water filters are readily accessible on the market and may be found in a variety of designs and configurations. Undercounter water filtration systems, countertop water filtration systems, pitcher water filtration systems, and faucet attachments are all available options. We’ve assembled crucial information for you to consider when selecting a drinking water filter, including a product-by-product comparison, filter pollutant reduction capabilities, installation requirements, and ongoing expenses per gallon of water treated.

Reducing Contaminants in Drinking Water

In order to assess the pollutant reduction capacities of a drinking water filter, there are two crucial parameters to take into consideration: Certification by the National Sanitation Foundation and the capacity to reduce chlorinechloramine. First and foremost, ensure that the filter you are contemplating is NSF Certified to Standards 42, 53, 401, and P473 (National Sanitation Foundation). It is also recommended that reverse osmosis systems be certified to NSF standard 58. “NSF Certification” is considered to be the gold standard for third-party certification in the industry since it is issued by the National Sanitation Foundation (NSF), which is the most reliable third-party testing body in the world.

Although most filters that have received NSF Standard 42 certification pass chlorine testing, they fail chloramine tests in the majority of cases.

Standard 53 of the National Sanitation Foundation (NSF) covers particular health-related pollutants such as cysts (for example, Cryptosporidium and Giardia), lead, volatile organic compounds (VOCs), and MTBE (methyl tertiary-butyl ether), which may be present in public or private drinking water.

The National Sanitation Foundation P473 verifies claims of decrease linked with the developing pollutants perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) (PFOS).

NSF Certification indicates that the filter has been extensively tested and validated by NSF to meet the manufacturer’s claims for these requirements, ensuring that the filter is of high quality.

A filter that decreases chlorine, chloramines, lead, mercury, volatile organic compounds (VOCs), and MTBE is likely to reduce additional contaminants as well.

As a result, most purification procedures struggle to minimize VOCs (Volatile Organic Compounds), which contain a high number of recognized carcinogens such as chloroform and benzene. As a result, passing the NSF 53 Certification test is extremely challenging.

Installing aDrinkingWater Filter

In most cases, installing a drinking water filtration system is straightforward, and pitchers require no setup either. Filters that connect to or mount on your faucet are simple to install and are compatible with the vast majority of standard faucet fittings available. Undercounter and reverse osmosis systems necessitate the drilling of an additional hole in your sink to accommodate an additional drinking water faucet. It’s a good thing that the holes cut out for drinking water faucets and soap dispensers are all the same size.

Even if you don’t have any more sink holes on your counter, you may hire a plumber to make one for you for a fee of around $100-$200.

Countertop water filters are a great alternative if an undercounter water filter is not an option for your kitchen or bathroom.

Cost of Drinking Water Filters

A high-quality drinking water filter should provide years of service. You will need to replace the filter cartridges on a regular basis in order to guarantee that the system continues to function and operate efficiently. The frequency with which you change your drinking water filter system is determined by the volume of water you utilize via the system. Once you’ve determined the cost and frequency of filter replacement, you can use this information to calculate the total cost of owning a drinking water filter as well as your cost per gallon of clean, filtered drinking water to use in your household.


  • A constant supply of filtered water – the most effective long-term option for in-home water filtration Typically, the most robust and effective filtering technique — it removes about 10 times the amount of pollutants found in the leading pitcher filter
  • And Dedicated on-sink faucet for filtered water on demand
  • Equipment is concealed behind the counter. Convenient and sophisticated — When compared to countertop or pitcher choices, these filters are often the most long-lasting.
  • This product is effective in removing heavy metals such as lead, fluoride, and arsenic
  • The use of RO systems in conjunction with sophisticated carbon block filters has been shown to remove more pollutants than any other single water filtering technology now available.
  • The availability of filtered water from the tap at all times. Superior filtration technique as compared to gravity-based pitcher filters – employs water pressure rather than depending on gravity to filter water
  • When compared to pitcher filters, these filters have a longer lifespan.
  • It is widely available and simple to obtain
  • The buying price is cheap at the outset. Typically, chlorine taste and odor are removed, resulting in better-tasting water. Portable — the pitcher may be stored in the refrigerator
  • The purchase price is often higher at the time of purchase. Installation is more difficult since most of them require you to drill a hole in your sink counter in order to attach a specialized faucet.
  • All RO systems generate wastewater, with the majority of them wasting more than 50% of the water that goes through them. Unless used in conjunction with carbon block filters, it will not effectively remove chemical contaminants such as volatile organic compounds (VOCs), herbicides, insecticides, and medicines. RO systems remove all dissolved solids, including naturally occurring minerals that are known to make water healthier and more pleasant to drink.
  • The majority of them can only be linked to basic faucets – they will not operate with sprayer faucets or other types of faucets. On the sink faucet or on the countertop, it might be cumbersome.
  • Filter life is limited, necessitating frequent replacement
  • Short filter life
  • Cost per gallon is higher, therefore this is a more expensive alternative in the long run. Gravity-based filtering is inconvenient and time-consuming
  • When compared to countertop and undercounter solutions, filtering technology is rather poor.
  • Filters for under the counter use, reverse osmosis filters, faucet attachment filters, and pitcher filters are all available.
