10 Best Faucet Water Filters: Reviews & Buying Guide

Drinking healthy water is a part of healthy living since it's involved in many fundamental bodily functions. However, your ordinary tap water isn't exactly that clean – in fact, it contains hundreds of different pollutants, from microorganisms to traces of heavy metals. These pollutants, in small amounts, aren't generally harmful, but they can be devastating to your health in the long run.

Luckily, you can now gain access to clean and healthy water right out of your tap, by simply installing a high-quality water filter into your kitchen faucet. It will effectively remove any chlorine, sediments, and other contaminants from your water, giving you bottled-quality water, straight out of your tap. However, to an untrained eye, all faucet water filters might seem the same, which is why we reviewed several of them.

We also included a comprehensive buyer's guide to help familiarize you with the different types of faucet water filters, and what to look for when purchasing one.

PUR FM-3700 Advanced Faucet Water...
  • FAUCET WATER FILTRATION SYSTEM – Enjoy cleaner, filtered water from your...
  • REDUCES LEAD AND 70+ CONTAMINANTS – This PUR drinking water faucet filtration...

Thanks to its attractive design and relatively affordable price, the PUR FM-3700 is one of the most popular best-sellers on the market. It provides a constant, steady flow of water, and contains a filter that’s effective at removing over 70 different contaminants from your water.

The device comes in a plastic housing, with a stainless-steel finish, that looks luxurious and appealing, especially when compared to all-plastic models. Thanks to this design, and the vertical placement of the cartridge, it will complement most faucets, without taking much space. Another selling point is easy installation – you won’t need any tools, and it only takes about a minute to install.

When it comes to filtration, well, this is where the PUR FM-3700 really shines, as it features a two-stage filtration system. The first stage removes sediments, heavy metals, chlorine, and cysts from the water, while the second adds minerals for a more refreshing taste. The filter has a lifespan of 100 gallons of water, which is equivalent to 750 bottles of water.

Of course, the device features an On/Off lever, allowing you to choose between filtered and unfiltered water, in case you want to do the dishes. If you seek pure water, the PUR FM-3700 is definitely a step in the right direction.

  • NSF Certified

Engdenton Faucet Water Filter

Engdenton Faucet Water Filter...
  • High-quality food grade 304 stainless steel housing, Cracking-proof and...
  • The most advanced Activated Carbon Fiber (ACF) filtration technology, inhibit...

The runner-up on our list is the Engdenton Faucet Water filter, which features excellent materials and a sturdy, high-quality build. But looking good isn't the only thing this water filter does, as it also removes over 99% of different contaminants from your water.

First, let's talk about the design – the Engdenton is a vertically placed faucet filter made of 11-gauge thick 304 stainless steel. This type of stainless steel is typically used for commercial food processing equipment, so you can’t really make a mistake with this model. It’s sturdy, crack-resistant, and looks good with any faucet. Not to mention that it weighs only 1.5lbs, and requires no tools to install to your existing faucet.

The Engdenton faucet filter swivels 360°, allowing you to make a water fountain out of your standard faucet. It also enables you to fill larger water bottles that usually wouldn't fit under your faucet. But good things don't end there; thanks to the unique filter design, this faucet water filter reaches a water output of 0.5gal/min. This is quite reasonable water flow, which equates to eight 8oz glasses of water in a minute. Of course, if you choose to handwash your dishes, the On/Off lever allows you to run unfiltered water through your faucet.

The Engdenton uses an activated carbon filter, which features a 320 gallons life span, and remover over 70 different contaminants, including organic waste, heavy metals, and pesticides.

The Good

  • Incredibly long filter lifespan
  • Excellent, sturdy build and attractive design
  • On/off lever

The Bad

  • Despite improvements, some users reported issues with the adapter

Waterdrop WD-FC-01 Tap Filter

Waterdrop WD-FC-01 NSF Certified...
  • NSF certifications: Tested and certified by NSF International against NSF/ANSI...
  • Long-lasting filter life: Each faucet filter provides 320 gallons of cleaner...

The Waterdrop is a newly established manufacturer that improves in areas in which others fail. As a result, the WD-FC-01 tap filter looks smart and sleek but also works like a charm. It features massive filter longevity, adheres to several NSF/ANSI standards, and does an exceptional job of purifying your water.

The product features a housing of seamless white plastic that's mounted vertically along the faucet. The faucet itself fastens between the filter and the on/off lever, effectively decreasing the pressure on the cartridge that's exerted by the water. It's a really simple, yet genius idea that increases the longevity of both the filter, and the product, and saves space.

The water purification on this device is unparalleled, as it features a five-stage filtration. Thanks to the pre- and post-filtration stainless steel mesh, more massive particles and sediments are removed before they even reach the filter. The pre- and post-filter PP cotton layers take care of smaller particles, while the activated carbon removes chlorine, chemical pollutants, and organic particles.

Unfortunately, despite its fantastic design, the manufacturer omitted a filter replacement indicator for some reason. Though you can run the device without it, knowing exactly when to replace the filter would be an excellent addition. Still, we highly recommend the Waterdrop WD-FC-01 faucet water filter.

The Good

  • Large filter capacity of 320 gallons
  • Overall fantastic design
  • Great quality plastic housing
  • Top-quality filtration

The Bad

  • No filter sensor or indicator of any kind

PUR PFM350V Faucet Water Filter

PUR PFM100B Faucet Water Filtration...
  • FAUCET WATER FILTRATION SYSTEM – Enjoy cleaner, filtered water from your...
  • REDUCES LEAD AND 70+ CONTAMINANTS – This PUR drinking water faucet filtration...

Just like the previous PUR water filter from our list, the PFM350V is not just a handsome looker but also an incredible performer. Besides delivering safe and healthy water, it also filters through various minerals, offering a crisp, refreshing taste of water.

The device comes with a metallic grey finish, though a plethora of other finishes is available, like the brushed stainless steel, or a white plastic housing. Still, the design is quite practical, as the purifier fastens to the faucet with any tools necessary. The adapter is placed between the on/off lever, and the filter itself, which significantly reduces the pressure exerted by the water.

As one of the best faucet water filters, the PMF350V features a fantastic filtration system that's certified to eliminate more than 70 contaminants. It removes heavy metals, like lead and mercury, sediments, and organic compounds. The manufacturer states that filter lasts for 2-3 months, depending on the water consumption; more specifically, it features a lifespan of 100 gallons.

Thanks to the MineralClear filter, the device filters water over natural minerals, which replenishes the mineral content of your water. The result is crisp, clean, refreshing, healthy water. However, keep in mind that not all filters are created equal, and there are cheaper replacements of lover quality. 

The Good

  • MineralClear filter
  • Fantastic filtration system
  • Stylish
  • Straightforward installation

The Bad

  • Not compatible with all faucets

  • REDUCES LEAD: Water filter system filters out 60 contaminants such as 99% lead,...

This model from Brita, one of the best faucet water filter manufacturers, is aimed at households with a mildly polluted water source. While aesthetically appealing and stylish, the filtration system is the main selling point of this particular model as it turns your regular tap into a spring of healthy water.

Besides the fantastic filtration features this model offers, the Brita is quite a space saver – it’s compact, so it doesn’t take up much necessary space. It comes in a glossy white BPA-free plastic that adds a specific bling to your faucet and your kitchen sink. Thanks to the improved housing design, Brita now fastens between the filter and the on/of lever, which reduces the overall size of the device.

When it comes to water purification, Brita might as well be a synonym for clean, healthy, and refreshing water. The filter is highly effective at removing rust, sediments, lead, and chlorine, thus improving the quality and taste of your water. It has a lifespan of 100 gallons, which is quite nice, considering the size of the device.

Additional features, apart from filtered/unfiltered water, include a spray option, which is pretty uncommon in faucet water filters. But being one of the best faucet water filters on the market, Brita increases water flow through this option. It's genuinely a fantastic water filtering product.

  • FEATURES: Reduces azine, chlorine, lindane, lead, particulates class I,...

Culligan has long been known as a well-reputable brand of household water treatment, as they make some of the best water filters available on the market. And they’ve got certificates to prove it, as they’re NSF certified against ANSI Standards 42 and 53, which means they deliver top-quality water.

The FM-15A comes in a compact, white finish plastic housing that mounts to most standard water faucets without the use of hand tools. Naturally, the device features an on/off switch that allows you to choose between filtered and unfiltered water, depending on your needs. All you need to do is pull the diverter valve stem to get a cleaner and healthier water.

Culligan FM-15A features a top-quality filter that removes all the bad taste and odor from your water, as well as more than 50 other contaminants. It's certified for removing chlorine, asbestos, lead, sediments, cryptosporidium, and giardia cysts. The cartridge has a lifespan of 200 gallons before it requires replacements, which can be anywhere between 2 to 5 months, depending on your water consumption. 

Unfortunately, the Culligan FM-15A doesn’t have a filter replacement indicator of any sort, so you’ll need to pay attention to the filter. Nonetheless, it’s still one of the best faucet water filters on the market, thanks to its fantastic water filtration.

The Good

  • NSF certified
  • Easy to install
  • Compact
  • Fantastic filtration

The Bad

  • The flow rate could be better (it’s only 0.5 GPM)

DuPont WFFM350XCH Deluxe

DuPont WFFM350XCH Electric Metered...
  • Easy-to-read electronic display shows how many gallons faucet water filter has...
  • Ultra performance filtration improves; taste, odor, and clarity of your water

This model by DuPont is a horizontal mount filter that features a compact design, providing you with more space under your faucet. It's a rather suitable choice for anyone looking to remove chlorine, benzene, sediments, asbestos, lead, mercury, and other impurities from their tap water. On top of that, it’s stylish and reasonably priced.

The device, with its chrome finish, looks aesthetically appealing and blends well with other kitchen appliances. However, DuPont recognized the need for several different finishes, and offers this exact model in white plastic, and brushed nickel finish. But regardless of the finish, this faucet water filter does its job beautifully.

Installation is pretty straightforward, as the device fastens to the faucet between the filter and the on/off switch, easily by hand. The unit is equipped with a top-quality filter that removes all the impurities from your water, thanks to the installed DuPont Patented Antimicrobial protection. It filters 200 gallons of water and features a unique sensor display, which lets you know when the filter needs replacement.

Despite its excellent filtering ability, DuPont recommends this model for municipal water only, advising the customers to avoid filtering well water.

The Good

  • Long-lasting filter
  • Easy-to-read display
  • Convenient and stylish design
  • Nice finish

The Bad

  • Shouldn’t be used above 100 PSI water pressure

WINGSOL Faucet Water Filter

WINGSOL Faucet Water Filter...
  • Durable - 304 stainless steel housing, durable and sturdy,cracking-proof and...
  • What is filtered – mainly reduce chlorine and improve taste, remove water...

304 stainless steel housing and filter life of 320 gallons are only some of the features that make WINGOSL such a great product. With a plethora of fantastic features and specifications, WINGSOL deserves to be among the best faucet water filters.

The WINGSOL filter is pretty straightforward to install to your existing faucet, and you can do it by hand, without any equipment. Of course, the device comes with comprehensive instructions on how to install, operate, and maintain the device. The entire housing is compact, saves space, and features a 360° full angle rotation, allowing you to direct the flow of water where it suits you the most.

When it comes to filtration, we already mention it can filter 320 gallons of water before the filter "runs out." Other than that, it filters out impurities like sand, chlorine, mercury, lead, and chrome from your water, improving its quality and taste. The flow rate could be better; however, as it sits at 0.5gpm, we consider it quite reasonable.

The only downside is the lack of a filter sensor, something which the device and its users would greatly benefit from. Other than that, we're quite satisfied with the WINGSOL faucet water filter, as it grants access to great-quality water, at an affordable price.

The Good

  • Straightforward installation

HOMY is another manufacturer whose filters gained the NSF certification for removing bad taste, odors, and other contaminants from your water. This particular model, for example, features a fantastic 5-layer filtration, with recyclable filters that leave no footprint on the environment.

Design-wise, the HOMY water purifier gives of a premium-quality vibe, thanks to the brushed stainless-steel housing, which creates a lead-free and BPA-free environment. It installs quite easily and quickly, with no extra tools required. The only thing you need to pay attention to is the faucet compatibility, as it fastens with only the standard types of faucets.

As we mentioned above, the filtration system is fantastic. It features several stainless-steel mesh barriers on the entrance, and activated carbon, tourmaline, and coconut shell fiber inside the filter. These remove both large and small particles, as well as 70 other contaminants, including lead, mercury, chlorine, fluoride, rust, and dirt. The filter also inhibits bacterial growth, providing you and your family with both safer and fresher water.

Among other, more notable features is the filter longevity – it filters 320 gallons of water before it needs replacement. Its life is further prolonged, over time, thanks to the on/off switch that allows you to switch between filtered and unfiltered water.

Instapure F2 Tap Water Filtration System

Instapure F2 ESSENTIALS Tap Water...
  • Lever on the F-2C allows the choice between filtered and unfiltered water
  • Certified ANSI/NSF for the reduction of Chlorine (Class II) taste and odor

The Instapure F2 is the right choice for anyone looking for a good-quality budged-friendly faucet water filter. It costs less than most models on our lists, and does a pretty good job of removing impurities – just don't expect the same quality as with PUR, or Culligan.

Still, it does a solid job of removing the contaminants from your water, including most impurities, like sediments, sand, rust, lead, microbial cysts, and volatile organic compounds. The filters are good for about 200 gallons of filtered water before they require replacements, which are incredibly affordable, saving you money in the long run. However, they're not meant for heavy-duty filtration and will struggle to remove higher concentrations of chlorine from your water.

When it comes to looks, the F2 doesn't fall far from the competition. The base of the filter, along with the adapter, is made from stainless steel, with a see-through plastic cap, and black plastic on/off lever. Thanks to the pretty straightforward design, the device is incredibly easy to install, and doing so requires no tools or any technological experience. Also, the entire filter is incredibly compact and saves a great deal of space around your faucet and kitchen sink.

If you want clean water on the budget, the Instapure F2 water filter is a way to go.

Buyer’s guide

In all honesty, water faucet filters are a fantastic alternative to home water filtration systems. However, most ordinary people don't know how to differentiate various types of faucet water filters, which can lead to an improper purchase. This buyer's guide aims to educate you on what makes the best faucet water filter and help prevent you from making a wrongful purchase.

In it, we'll cover everything there is to know about faucet water filters, from different types of faucet water filters to their most essential characteristics. But first, let us introduce you to faucet water filters and the way they work.

You may also read the buying guides of bathroom vanity for small spaces.

What are faucet water filters and how they work?

As their name implies, faucet water filters purify the water that goes through the faucet they’re mounted on. They’re also much more convenient than filtering pitches and whole-home filtration system, by simply being more effective, and accessible. Of course, there are different types of faucet water filters, which we’ll cover in a moment, but first, let’s discuss how faucet water filters work.

As we said, water faucet filters are attached to your existing faucet, with the filter built into the device. The water would then run through the tap as it would normally do, but not before running through the filter. During that process, the filter purifies the water either mechanically, by trapping the impurities, or chemically, by binding them to the filter. That way, the regular water flows through the filter, and purified water runs out of your tap, into your glass.

Thing’s to consider when purchasing a faucet water filter

There are many different products on the market, and knowing what to look for is rather important. To help you choose the product that suits you best, we listed vital features you should consider when purchasing a faucet water filter.

Type – Mainly, there are two types of faucet water filter, with the first being more popular than the second. The most popular type is attached to your current water tap, with a built-in filter that purifies the water. It’s rather easy to install, as you replace your tap's aerator with the device, which makes this type so popular. It also allows you to choose whether or not you want to use filtered or unfiltered water for different purposes.  The under-sink faucet water filter, appears just like a standard faucet, with the filter attached under the countertop. However, it's wholly dedicated and offers no choice between filtered and unfiltered water.

Style and Size – Though they perform almost the same, style and size matter, so let's discuss size first. As they're attached to your existing faucet, it's rather crucial that you fully acknowledge the size of your faucet and the faucet filter before you install it. Pairing a disproportionate filter to the faucet may prove to be problematic, as you’ll have to deal with a larger filter. This happens due to the common misconception that larger filters capture more contaminants, which isn’t necessarily the case. When it comes to style, most "twist-on" models are made of high-quality plastic. However, plastic models proved to be an eyesore for some users, which is why some manufacturers opted to use 304 stainless-steel. This is actually a food-grade type of stainless steel, which has a more luxurious feel to it.

Filter cartridge types – Different filters are better at containing and eliminating different impurities, which is why it's important to know what impurities your water contains. If you're not familiar with contaminants that plague your water supply, take a water sample for testing. It will tell you precisely what contaminants your water contains, and their exact concentration so that you can choose filter type accordingly.  There are two distinctive filter types: carbon filters, and reverse osmosis. Carbon filters are great for removing different chemicals, heavy metals, and larger particles from your water. Reverse osmosis, on the other hand, will eliminate almost any contaminants from your water. However, it works best if more substantial particles are removed ahead of it. For that reason, the combination of these two filters is the best, but unfortunately, rarely available in faucet filter models.

Filter lifespan and usage – Filters are usually effective for a certain amount of water, with their lifespan ranging from 100 to 500 gallons of water. Their longevity often depends on the quality of the filter, so please take price and quality into account. Also, consider the amount of filtered water you need daily. Make sure to purchase a filter that you won't have to replace too often, as it can cost you more money over time.

Filter Cleaning Sensor – Filter sensors serve to notify you when's the time to replace your filter, either by a light indicator or a day counter. The light indicator sensor is the most common sensor type and does an excellent job of tracking filtering capacity. In the beginning, the light is green and turns yellow over time. When the light turns red, the filter has reached its maximum filtering capacity, and can't purify your water entirely.Day counting sensors aren't as usual in faucet water filters but don't be surprised if you run into one. The sensor counts days since you last changed the filter, and you reset the counter with every filter replacement.

Filter replacement – To make life easier, you should look for a model that allows easy and comfortable maintenance. Replacing old and used filters with new ones is extremely important if you wish to have constant access to clean water. Of course, different brands feature different approaches to maintenance, like push-button or twist-and-lock, so choose the one you're most comfortable with.

Cost – Price is an important part to consider, and despite being affordable, you shouldn’t make a hasty purchase, when buying a faucet water filter. Faucet water filters are indeed a more affordable water filtration system, compared to whole-home systems; however, there are many options on the market. More affordable options will, undoubtedly, provide you with clean water. But higher-end models tend to feature alkaline filters included, which make your water more alkaline.


Drinking clean and healthy water is an integral part of a healthy lifestyle. We hope our article helped you choose a faucet water filter that best suits your needs. Still, we would like to recommend our top pick, the PUR FM-3700 3-Stage Advanced Faucet Water Filter, as it has all the features of a top-quality product.
