A faucet water filter gives you access to clean water right at your kitchen sink. Installation is a breeze without the need for tools and advanced plumbing skills, and you are not even required to make any permanent changes to your plumbing system which is great for renters.
What’s more, faucet mounted filters are really convenient to use and, compared to other water treatment systems, they are surprisingly affordable – a real alternative for people on a tight budget that want to protect the health of their family without spending a fortune.
But how do you find the best faucet filter? Don’t worry, this guide will help you do just that!

There are a couple of things that you should consider when shopping for a faucet mount water filter. These are:
In theory, the best water filter faucet you can buy is one that is customized to the contaminants present in your water. So your first step should be to figure out its quality.
You can do this by either conducting a test or by reviewing your municipality’s free annual Consumer Confidence Report (CCR) if you are on tap water.
In case you receive water from a well, or you are worried about contaminants dissolving into your water along the way from the treatment facility to your place, we definitely recommend you test a direct sample of the water in your home.
Once you know about all the water pollutants you are facing look out for filters that are NSF-certified to remove all or at least the majority of them. NSF certifications are the best guarantee for effective contaminant reduction.
That being said, many faucet water filters will only help to improve how your water tastes and smells. But there are also those that do a great job at filtering out lead and other heavy metals and all kinds of chemicals. You will find products from both categories in this guide.
Unfortunately, we don’t know of any faucet filter that would make hard water soft.
Just as important as a water filter’s capability to remove certain contaminants is its faucet compatibility.
Generally speaking, faucet mounted filter systems are incompatible with
Obviously, there are exceptions to this, but if your kitchen or bathroom faucet falls in one of these categories you want to double check that it’s compatible with a water filter before you spend any money.
The vast majority of standard faucets should be fine and there is always the option to use an adapter. In fact, most sellers include a couple of adapters with their products.
Kitchen or bathroom tap doesn’t really make a difference. What’s important is that it’s standardized.

The Brita Complete FF-100 is the best and also the best selling faucet filter on Amazon at the time of writing (or rather updating) this guide.
What we like about it are the certifications against NSF standards 42, 53 and 401. While Standard 42 is only for the reduction of chlorine taste and odor as well as larger particulates, Standard 53 is for water contaminants with health effects and Standard 401 for emerging chemicals.
To give you a quick overview, the Brita FF-100 is guaranteed to remove lead (>99.3%), asbestos (>99%), TTHMs (>98.7%), chlorine taste and odor (97.5%), particulates class I (99.7%), dozens of VOCs (at least 95%), and chemicals such as BPA (99.1%) and Ibuprofen (94.9%).
Please note: This is only an excerpt from the testing data.
In other words, this faucet filter is your best chance if you want clean and great tasting drinking water right from the kitchen tap.
Other than that, the filtering capacity is pretty average – 100 gallons or up to 4 months – and filters can be replaced with a simple click. By the way, they are reasonably priced.
Rated service flow: 0.58 gpm
One click is also all that’s needed for mounting the unit. 2 different adapters are included in the package in case your faucet has inside threads.
What’s more, you can easily switch between filtered and unfiltered water. It’s a great way to extend the life of filters and save money by only using filtered water when really needed.
Speaking of filter lifetime, the built-in reminder light lets you know when it’s time for a new cartridge.
Lastly, we wanted to mention the Brita recycling program real quick. It allows you to send back any used Brita products as long as you collect a minimum of 5 pounds before shipping. Then, simply request a shipping label and drop your package off at the nearest UPS location.
Brita has partnered with TerraCycle, an award-winning recycling company that separates and shreds all the materials to make new recycled products.
What about flaws?
A number of users have reported that the Brita Complete kept falling off, either because the collar or one of the adapters failed, or simply because the adapters are too flimsy. Tip: Visit your local hardware store and buy a metal replacement.
Another issue is the filter life indicator that has a tendency to stop working all of a sudden. The battery inside cannot be switched out, meaning you have to purchase an entire new base or do without the indicator.
We also read complaints about smaller leaks here and there and reduced water flow which is typical for faucet filters – nothing out of the ordinary.
All in all, Brita’s Complete FF-100 features a solid filtration process with good contaminant reduction rates, it is simple to set up, and even easier to use. Drawbacks are the sometimes faulty faucet connection and the filter indicator light. Our rating: 4 stars!
As an alternative to the Complete FF-100 faucet filter, Brita offers the Basic SAFF-100.
The reason why we recommend you go with the Complete FF-100 and not the Basic SAFF-100, although it would be cheaper, is because with the Basic it’s more difficult to switch between filtered/unfiltered water which oftentimes requires both hands.
Chrome and stainless steel are our favorites here, as they tend to blend best with other kitchen appliances.
That being said, they all make use of the same filter(s), namely the PUR MineralClear or the PUR Basic. You are free to choose between the two.
Where is the difference? In terms of contaminant removal, there is none. Also, both have a 100-gallon filtration capacity. However, the PUR MineralClear “filters water over natural minerals for great taste”, the PUR Basic doesn’t. This might be why the PUR Basic is a tad cheaper. Can you taste the difference? Honestly, we don’t know.
Anyway, using activated carbon and ion exchange media, PUR faucet filters are certified to reduce over 70 contaminants from water, such as:
All reduction rates are according to NSF standards 42, 53 and 401. In other words, a PUR faucet filter will make your stinky tap water significantly cleaner and better tasting, and turn it into a delicious cocktail (just kidding).
One-click installation? Check. Adapters + washers for most internal/external threaded standard faucets included? Check. Pro tip: If the unit does not fit your tap make sure to contact PUR and they will send you a suitable adapter for free.
Another feature that you might find useful is the indicator light that tells you when it’s time for a filter replacement. Like we said, the rated filtering capacity is 100 gallons or 3 months of use.
Depending on the condition of your water source, you might have to change filters more frequently though. But don’t worry, it barely takes 2 minutes and new filters are cheap, especially when bought in bulk.
To extend their lifetime you can switch between filtered/unfiltered water by using the lever at the side.
The service flow rate is 0.52 gpm, so a little bit slower than the Brita Complete.
And just like Brita, PUR offers a program to recycle all your PUR products with TerraCycle.
While most users have no issues at all, reading dozens of customer reviews we stumbled upon a couple of complaints that came up repeatedly.
For one, many reviewers said that the thin plastic construction is not built to last. The filter housing is particularly fragile. Hair line cracks are not uncommon. The result: Leaks and water spraying everywhere within months after purchase.
In addition, the wiggly system-to-faucet connection might not be water-tight.
Also, for some users the water flow slowed down considerably after only a few weeks, while for others the water started sputtering out of the main spout as if it was clogged.
With this PUR faucet water filter the taste improvement is substantial. Plus, it rids your water of a bunch of potentially harmful pollutants. On top of that, it’s affordable and easy to connect and use. But there are issues that could definitely do with an improvement. 3.5 stars.
What makes the Engdenton faucet water filter system stand out is that instead of cheap plastic it is made from 304 food-grade stainless steel for sturdiness and durability, so no leaks due to cracking as is often the case with the plastic models.
As far as the filtration is concerned, activated carbon fiber improves water aesthetics, removing most of the chlorine and all kinds of debris including sand, rust and dirt.
The maximum filtering capacity is 320 gallons of water or 6 months which is a lot more than what you get with Brita or PUR. Above that, replacement filters are super cheap. To be fair, though, the Engdenton does not nearly remove the same amount of contaminants (at least it is not certified to do so).
Standard adapters for mounting the unit are included. By the way, the installation barely takes more than 5 minutes even if you are not very handy around the house.
Stainless steel or not, the Engdenton is reportedly still leaking, mainly between the adaptor and faucet.
We also miss a performance data sheet with specific contaminant reduction rates in combination with NSF certifications.
We love that the Engdenton faucet water filter is made from durable stainless steel rather than flimsy plastic. However, this does not solve all problems with leaks.
Considering that the filtration is very basic we would recommend this product to anyone who is mainly concerned about water taste.
Next, let’s take a look at what Culligan has to offer when it comes to the best water filter faucet.
The Culligan FM-15A water filter comes in white which looks a little cheap (just being honest).
Its older brother, the FM-25, has a nice chrome finish that blends much better with other kitchen appliances and costs only a few dollars more – this update is definitely worth the extra money!
Apart from looks, what’s the big difference between the Culligan FM-15A and the FM-25? Simply put, there is none.
Tested against NSF Standard 42 and 53, both provide a simple solution for better tasting and somewhat cleaner drinking water free from odors.
To be a bit more specific, the carbon block filter reduces sediments and turbidity, 97.4% chlorine, at least 98% lead and 98.9% lindane among a couple of other contaminants.
Other pros are:
The biggest flaw? Quite a lot of users cannot get the filter housing open. After a couple of days/weeks use the cap gets stuck and simply won’t move which makes the whole replacement process a real pain.
Another problem we have is that filters are considerably more expensive than the competition. Annual cost: ~$85 USD.
We also read reports about leaks along seams or due to cracked filter compartments and customers receiving defective products.
The Culligan FM-15A and FM-25 faucet mount water filters provide H2O that tastes better than plain tap water. That’s for sure. They are easy to use, they blend in nicely with other fixtures, and they are very effective at filtering out lead. Taking into account the housing cap design flaw, it’s 3.5 stars from us!

We decided to review the Waterdrop faucet water filter for 2 reasons:
Whether this is true or not you are about to find out!
First of all, Waterdrop water filters really seem to last much longer than the competition. 320 gallons might be a bit exaggerated, but 6 months is realistic which is about twice as long as what you get out of a Brita or PUR faucet filter. The price is also hard to beat.
Does the Waterdrop really remove fluoride from water? Although we did not test this ourselves, we highly doubt it. The filter uses activated carbon fiber that is supposed to be 10-12 times more adsorptive than regular carbon, but that does not mean that it will affect fluoride content.
Taking a closer look at the multi-stage filtering process, the “advanced filtration layer” might help with fluoride. It is also supposed to reduce lead. By how much? We don’t know.
The only reduction rate that has been specified is free chlorine and that’s 93% for improved water taste and smell (more on this in the cons section below).
Apart from that, we have a lever for choosing between tap and pure water which will prolong filter life.
Furthermore, Teflon tape and 6 different adapters + plenty of washers are part of the deal so you should find something that fits your faucet.
Water flow rate? .5 gallons per minute which is pretty standard.
If you ask us, the filtration seems questionable. We couldn’t find any testing data or NSF certifications that would confirm the fluoride reduction claims.
We also don’t like that the Waterdrop system has a hard time staying on the faucet and not just pop off.
Leaks are another common issue even with enough Teflon tape applied and no matter how much troubleshooting is done.
This is not our favorite faucet water filter for sure. There are too many problems with the faucet connection and the filtration claims are suspicious at best. 2 stars.
The CuZn bathtub faucet water filter supposedly does two things:
The purpose of this is to “alleviate water quality issues that may contribute to dry, itchy, flaky skin, brittle hair, eye, lung and sinus irritation” while bathing.
What is the secret of the CuZn bath ball that provides for a more pleasant bathing experience, smoother skin and softer hair?
It’s KDF-55 filtration media, a copper-zinc blend which is not that big of a secret actually.
However, the CuZn uses a KDF-55 media foam disc. The foam is more effective at removing contaminants than granular KDF as it allows for a longer contact time with the water, says the manufacturer. Also, the surface area is 50 times larger.
Personally, we like that no plastic housing is required so the replacement filters are 100% recyclable.
Speaking of which, one filter disc is good for up to 12 months (seems a bit too long to be honest) and the replacement is super simple.
As usual, the biggest issue that we have is that the manufacturer does not provide a performance data sheet, so we cannot possibly tell how effective the CuZn bath ball really is. For some users it seems to work, for others it didn’t (chlorine levels stayed the same).
Also, the ball is just not very practical since it can be hard to keep it directly underneath the tap.
The CuZn Bath Ball is for people who want a quick, easy and inexpensive solution to fill their bathtub with kinda filtered water. Most reviews are positive with customers seeing an improvement in the health of their hair and skin. 3 stars!
DuPont offers not one but two faucet mount water filters that could be of interest to you. The first is the DuPont Premier with the model number WFFM100. The second is the DuPont Deluxe with the model number WFFM350.
They are both compatible with DuPont High Protection and DuPont Ultra Protection Faucet Mount Cartridges. Or simply put, all DuPont faucet mounted systems and cartridges are interchangeable.
And no matter which combination of faucet filter and filter cartridge you choose, the achieved water quality is pretty much the same. Here is an excerpt from the performance data sheets:
Certifications for NSF Standard 42 and Standard 53 were awarded for guaranteed contaminant removal. Rated service water flow: 0.45 gpm.
As you can see, the filtration goes beyond simple chlorine reduction for improved water taste and clarity. Especially toxic lead is also taken care of.
But then where is the difference between the DuPont Premier and the DuPont Deluxe?
First of all, the latter is available in chrome, brushed nickel and white, whereas the former only comes in chrome. What’s more, the DuPont Deluxe features an electronic display that tells you exactly how much water has been processed yet. This makes timely filter replacements much easier and you can make sure that your drinking water is getting cleaned effectively at all times – we love it!
By the way, the DuPont Deluxe includes an Ultra Protection cartridge with 200 gallons capacity (or up to 3 months). The High Protection cartridge that you get with the DuPont Premier only lasts for a hundred gallons (or up to 3 months).
Another difference is that the DuPont Deluxe comes with a 4-year, the DuPont Premier with a 3-year limited warranty that has you covered in case anything goes wrong.
A common feature is that both filtration systems are designed to easily attach to most standard kitchen faucets. 2 metal adapters + plumber’s tape are included.
Also, with each filter system you can choose two types of water flow: Filtered and unfiltered.
Unfortunately, leakages are quite common with both DuPont units. Some customers even had problems with the filters not holding onto their faucets.
One issue that only affects the DuPont Deluxe is the electronic display that in some cases simply quit working or read random numbers.
And getting a helpful response from the DuPont customer service is not easy either.
If you are looking for a cost effective solution to delicious tap water, this might be it. However, due to the problems with the display we recommend you go with the standard DuPont WFFM100, although we know that the DuPont WFFM350 is more popular. You can still upgrade to the Ultra Protection cartridges to double your water filtration capacity.
Let’s make this quick:
The Chloler CHL-FF-297 faucet water filter looks very similar to the Waterdrop reviewed further above. We even found (almost) identical images in their product descriptions. This plus the fact that Chloler Inc is a private label company makes us assume that there is not much of a difference between the two.
In short, the activated carbon fiber is good for chlorine reduction and maybe takes care of a couple of other organic water impurities, and that’s about it.
One benefit is the extended filter lifespan of 320 gallons or up to 6 months, whichever comes first. This is 2-3 times the performance than the market standard. Moreover, replacement filters are a real bargain.
But as we already said reviewing the Waterdrop, we don’t believe that this faucet filter touches fluoride at all. And there are no lab reports that would support this or any other contaminant reduction claim.
For more details, check the Waterdrop review.
Bottom line: No buying recommendation.
In a nutshell, the faucet water filtration systems use the same filter cartridges that the vertical series uses, so you can expect identical results. Although if you take a really close look comparing the performance data sheets you will notice that PUR horizontal water filters are certified to remove 99.7% lead, whereas the vertical models “only” reduce 99.3%.
And again, you can choose between working with PUR MineralClear or PUR Basic filter elements. Both are rated at 100 water gallons which is the standard in the faucet realm. They also are NSF certified to remove the same contaminants (more than 70 in total; learn more above).
So where is the difference, you ask? The PUR MineralClear enriches your water with minerals for improved taste. The PUR Basic does not, which is probably why it costs a little less.
As far as the installation goes, unlike PUR vertical systems, the horizontal models do not feature a one-click install. But don’t worry, all you have to do is tighten the threaded mounting nut onto your faucet. Adapters + washers are included. If they don’t fit, reach out to PUR and they will send you a suitable replacement for free.
Water leaking from the bottom of the housing, water leaking straight out of the front of the housing, water leaking from the handle – water coming out of these units where it is not supposed to come out is a major problem and also the main reason for the subpar customer feedback.
Another common problem are malfunctioning indicator lights that stop working after the first or second filter replacement.
It’s sad that we can’t rate PUR’s horizontal faucet mount water filters with more than 3 stars, as they provide solid filtration and especially the MineralClear filter elements leaving the water taste good.
However, the leaking and the erroneous filter replacement indicators make buying these products like playing Russian roulette. Maybe the company should consider a redesign to increase sturdiness and prevent cracking and other durability issues?
More on Faucet Water Filters
In section 1, we reviewed the top rated faucet water filters on the market. Next, we are going to tackle some of the most common questions our readers ask about them.
Do faucet water filters really work and are therefore worth their money? Or should you better invest your hard-earned cash elsewhere, such as in a reverse osmosis under sink water purification system, a POE water filter or a filter pitcher?
Great question! Let’s get to the bottom of it:
If we take a look at the various performance data sheets that manufacturers have provided for the faucet filters reviewed on this page, you will find reduction rates far beyond the 90 percent benchmark for common water contaminants such as lead, chlorine, asbestos and mercury.
On a side note, if you are looking for a more thorough guide on lead purification, follow this link: https://www.best-osmosis-systems.com/water-filters-for-lead-removal/
Many filters systems are also certified to significantly reduce chemicals like volatile organic compounds, TTHMs and BPA as well as different pharmaceuticals, pesticides and herbicides.
Faucet filters that remove pathogens – think cysts – are harder to find.
So to answer the question, yes, faucet water filters do really work. Although, whether or not they will work for you depends on what impurities you want to have removed.
For example, if you are trying to get rid of fluoride, a faucet filter won’t suffice. The same goes for arsenic or chromium. If your main concern is bad water taste due to high chlorine content, almost all faucet mounted filters will work just fine.
Bottom line: Find out what it is in your water that is causing you a headache. Then go out and try to find a suitable filter.
Finally, let us briefly discuss the pros and cons associated with faucet water filters.
Faucets with built-in water filters might exist, but if they do we couldn’t find them.
By the way, the reason why we mention this is because we get this asked quite a lot by our readers.
This might be a great idea for a new startup!
