Best Faucet Water Filter Products

What is the best water filter for faucet?

If you’re looking to improve the taste of your municipally treated water and protect your body from harmful contaminants such as chlorine, chloramine, lead and other chemical byproducts, then you might want to check out faucet water filters. These puppies differ from other filtration systems, such as RO (reverse osmosis), undersink filters, countertop filters and carafes in that they mount, you guessed it, directly onto the faucet. On that note, even the best faucet water filters are competitively priced compared to some of the RO systems. On that note, they aren’t designed to treat unhealthy water and make it potable, but rather take treated water and make it more palatable. Also, with faucet filters, there’s no water wasted, and most models will let you switch between filtered and unfiltered water, so you won’t be wasting the cartridges, either.

Top 5 Best Faucet Water Filter Reviews

If you’re looking for the best drinking water filters on the market mention, check out our list of top five models – we made sure to include a little bit of something for everyone’s taste. Of course, seeing as these puppies will need to have their cartridges changed every once in a while, we included some links to the replacements, though it’s easy to get hold of replacements filters for all five models at your local retailer’s, as well.

PUR 3-Stage Advanced Faucet Water Filter

The PUR 3-Stage Advanced Faucet Water Filter is definitely one of the top selling drinking water filters, at least on Amazon (though, come to think of it, it’s a clear enough indication).

Filtration and Capacity

The PUR 3-stage filter does a great job of filtering well over 70 per cent of all contaminants using natural minerals (as opposed to synthetic, obviously). To be exact, it tackles 99 per cent of lead, 92 per cent of pesticides, 96 per cent of mercury, as well as microbial contaminants and other assorted whatnots, though it doesn’t filter fluoride.

The carbon filters are made from coconut shells that are steam-treated in order to make them as porous as possible. We’ll trust their math and say this creates about 200,000 square feet of area, which is more than enough nooks and crannies to trap most pollutants from your municipal water. Sure enough, the filter will will slow down the water flow, but on the flipside, you’ll be drinking crisp, fresh tasting water instead of the usual municipal sludge. In case anyone’s wondering, yes, there’s one cartridge coming with the purchase.

Speaking of cartridges, the average capacity for this model is 100 gallons per cartridge. Now, depending on how many people are living in the house, this should hold you anywhere between one and three month, including cooking and pets (please, don’t cook he pets). All jokes aside, though, the filter does include a built-in electronic indicator, which will let you know when your cartridge is just about done. It starts off green, flashing a few times when you insert the cartridge, then at some point it’ll flash yellow to let you know it’s almost time, and finally it’ll flash red when the cartridge is used up completely. On that note, getting a replacement is easy enough, you can either order them via Amazon, The Home Depot, PUR’s own site, or just walk in a store and get it from your local retailers.

Installation and Key Features

The filter installs easily enough, and you should be able to do it in about five minutes, give or take, though there’s the option to order it with expert setup (of course, this pays extra). The whole rig is a 1-click installation clip-on (there’s an older model that screws on, but this is just as secure) comes with everything you need to connect it to the sink. There are 4 different connectors, and one of them is bound to fit your faucet. Of course, you’ll need to keep in mind that this product is mostly plastic, so it’s not really heavy-duty (the plastic threaded Type A adapter is notorious for being not exactly up to scratch).

The filter features a 360-degree swivel so that it can work with most standard sinks. It’s compatible with any standard faucet, although not the pull-out or handheld models. While we’re on the subject of compatibility, you should always make sure not to run hot water through it (it’s specifically stated so in the manual). There’s a switch on the side of it that lets you bypass the filter when you need to do the dishes or wash hair or whatever it is you do in your sink (we’re not judging).

As for the electronic indicator, it’s important to note that the battery for it is not replaceable, though looking on the bright side, the valve will have stopped functioning properly well before the battery dies. This is as good a time as any to mention the filter comes with a 2-year limited warranty.

Finally, as the aesthetics goes, it’s worth mentioning that the filter comes in three distinct flavors – Chrome, Gray and White, though the first one definitely looks the keenest (not to mention the fact it’s the cheapest of the three).
Best faucet filter do we think ? Well we have to say the PUR 3-stage filter ticks all the boxes.




Culligan FM-15A Faucet Mount Filter with Advanced Water Filtration

If you’re looking for the best sink water filter money can buy, then you might want to check out the Culligan FM-15A faucet mount filter with advanced water filtration. The FM-15A is a bestseller on Amazon, which speaks volumes in and of itself. Moreover, the rig has been NSF tested and certified against ANSI 42 and 53 Standards, so you can enjoy some peace of mind.

Filtration and Capacity

The “advanced water filtration” that’s mentioned in the name removes a great deal of contaminants, both organic and inorganic. According to Culligan and the NSF, the FM-15A filter removes 96 per cent of atrazine, 97 per cent of chlorine, 98 per cent of lindane (not an issue if you live in California), as well as any bad taste and odors. It takes care of all sorts of microbial contaminants – cysts, bacteria, the whole shebang. It doesn’t remove fluoride, though, so if you’re keen to get one that does, you might want to look elsewhere.

The filter has a flow rate of 0.5gpm at 60psi. To put it in terms that are easier to picture, a single 8oz glass should take under 10 seconds to fill when the cartridge is new. Once you notice the flow starting to weaken (basically, if it takes longer than ten seconds for the glass to fill), you should change the cartridge. That said, you would probably do well to have a spare one on hand. The filter does come with a complimentary FM-15RA cartridge, and you can find a replacement with no issues whatsoever. Now, while we’re on the subject, you should know that on average, you’ll need to make the change every three to four months. Although, that will depend on how many members you have in your household, if you have pets, how often you cook/eat at home, you know the drill. Still, three months sounds like a good frame to work with.

Installation and Key Features

The FM-15A is a compact kit that mounts directly on any standard faucet. The installation requires no tools at all, and anyone who’s ever played with LEGOs should be more than capable of doing it in a matter of seconds. You can install it in right-hand or left-hand orientation, whichever floats your boat. Of course, you’ll be getting an instruction manual with your purchase, and even if it’s missing, there are plenty of useful videos online.

As we mentioned above, the filter is compatible with most faucets, barring the drop down models. There’s a convenient diverter tab to switch between filtered and unfiltered water when you need to do the dishes or whatever else doesn’t require fresh, crispy tasting water. The whole rig is fairly durable, as it is designed to work within 30–100 psi range. On a similar note, it shouldn’t ever be used with scalding water, though it’ll work within the 40–100 degree range (Fahrenheit, or approximately 4–38 degrees Celsius).

Another selling point of this puppy is that it comes with a 2-year warranty, limited (pretty much the standard in the industry), and that it’s available in two nice-looking finishes – White and Chrome.



Aquasana AQ-5300.55 3-Stage Under Sink Water Filter System

The Aquasan AQ-5300.55 is one of the bet drinking water filters on the market, and it comes with a matching price. It’s the priciest item on our list, but no one would go as far as to actually call it expensive. It’s also important to note that the filter is NSF tested and approved against multiple standards and protocols – 42, 53, 401 and P473. As a matter of fact, it’s one of the 17 Aquasana products that are collectively the first products to receive the P473 certificate.

Filtration and Capacity

The Claryum Technology filtration system of the AQ-5300.55 is able of handling 68 different contaminants, organic and inorganic alike, reducing up to 98 per cent of them. The list includes all the usual pollutants you can find in your municipal water – chlorine, chloramines, lead, mercury, asbestos, various pesticides and pharmaceuticals, as well as a whole host of nasty business. So, whether it’s for drinking or cooking with, you’re guaranteed to get as fresh and as clean water from your tap as possible. And, no, it doesn’t remove fluoride.

The AQ-5300.55 can filter through about half a gallon each minute, or, to paint a picture – it will fill an 8oz glass in under ten seconds, and it will continue doing that with the rest of the 76,792 ounces (just shy of 600 gallons) of water until you have to replace the filter. There are three filters to each rig, and you’ll get them with the purchase, no worries.

On that note, the filters have no shelf life, but if you’re looking to get an estimate, they should be good for up to six months, provided you’re running an average household – kids, pets, you know the drill. You’ll know the filters need replacing once the water flow starts slowing down and the water starts tasting funky again. Short of that, you can simply pay attention to the indicator light, or, better yet, wait for the alarm built into the filter unit to sound off – the AQ-5300.55 really takes out all the guesswork. Both the alarm and the indicator light are powered by a single lithium metal battery (the kind that powers a wristwatch) with the average lifespan of 1590 hours. For replacement, the AQ-5300.55 filter uses the Aquasana AQ-5300R 3-Stage Under Sink Genuine Replacement Filter Cartridges, which you can find on Amazon.

Installation and Key Features

The installation is pretty straightforward and should take under five minutes, whether you know what you’re doing or not. Keep in mind that this is an undersink unit while you’re planning where to put it. Of course, there’s an instruction manual, and if you’re more of a visual type of plumber, there are some useful instruction videos online. The system uses a 3/8-inch intake and ¼-inch output to connect, and everything that comes in will come out – in other words, there’s no water wasted (until it finally breaks down after two–three years of faithful service). On that note, we should mention that it comes with a 1-year warranty, so ensure it’s fitted correctly to avoid any risk of the warranty being made nulled.

Finally, it’s worth mentioning that the AQ-5300.55 is available in three finishes, each progressively more expensive (though not by much, considering the overall price) – Brushed Nickel, Chrome and Oil-Rubbed Bronze.



Brita Faucet Water Filter System with Light Indicator

Brita has long ago become a household name when it comes to water filtration systems, and their Faucet Water Filter System (with Light Indicator) definitely contributes to justifying the reputation. It’s quite a cheap option, especially considering it has a light indicator to let you know when the cartridge is out of commission. On that note, the replacement filters/cartridges are just as cheap, so if you’re looking for the best faucet filter for as little money, then you might want to check out this one.

Filtration and Capacity

The filtration system takes care of chlorine and chloramines, getting rid of that nasty taste and odor of treated water. It also reduces lead and asbestos, as well as other sediments found in tap water. If you haven’t had any experience with faucet water filters, you might feel the flow is a bit underwhelming, but it’s supposed to function that way, don’t worry. There are several exit holes underneath the filter unit which are there to aerate the stream (prevents splashing, ensures even pressure and prevents wasting water).

A single filer is included with the purchase, and getting them either online or at your local retailers is easy enough, filters are good for 100 gallons, or about three months for the average household of four (that includes cooking and pet water, as well).

Installation and Key Features

Slick design, easy to install, easy to use, the Brita Filter hits the trifecta there. You can have an expert come and set everything up for you, but it’s really not all that complicated to do on your own (provided you know the difference between a sink and a faucet, that is). On a more serious note, the filter should fit most standard faucets, you’ve got instruction pretty much all over the place – on Amazon, Brita’s website, the instruction manual that comes with the purchase, YouTube, you name it. comes with an adapter kit (a selection of male and female adapters) that you can use attach it to pretty much any faucet, though it won’t work with the models that have a detachable sprayer on the mouth. Remember to flush the filter for a couple of minutes, 5 tops, before drinking the water. As an aside, the plastic threaded  connectors aren’t exactly up to scratch, so you would do well to get metal threaded ones from the hardware store, or, better yet, contact Brita and ask them to mail you some – it should be free of charge.

There are two models, one that allows you to switch between filtered and unfiltered water and another that adds spray mode, which is great for when you’re doing the dishes and need to rinse them; there’s a slide lever to switch between these, handily located on the side of the casing, of course, you should keep in mind that the filter was not designed with hot water in mind, so use it only with cold water, and bypass it if you need warm or hot water.



PUR PFM400H Chrome Horizontal Faucet Mount with 1 Mineral Clear Filter

The PUR PFM400H is a real beauty, and definitely one of the best water filters for faucets on the market – it hits the sweet spot between price and quality, all the while delivering fresh and crispy tasting water straight out of the tap.

The PFM400H uses Maxion Filter Technology which employs natural (as opposed to synthetic, obviously) minerals to filter out the usual sediments and contaminants from your tap water, including, but not limited to – lead (up to 99 per cent), mercury (up to 96 per cent), pesticides (up to 92 per cent), as well as well over 70 other known pollutants.

In case anyone’s wondering, yes, you do get a cartridge with the purchase, and the replacements are just as easy to come by. Speaking of replacement, the filter has a capacity of 100 gallons, or about two to three months of regular use.

Installation and Key Features

The PFM400H installs easily enough, mounting horizontally (though there’s a vertical model, as well). It comes with built-in threading so you can simply twist it onto your sink, as well as multiple adapters (male and female) to cover most standard configurations. However, the filter is not compatible with pullout or handheld faucets.

The filter features a side mounted 90-degree ball valve allows you to switch between filtered and unfiltered water, which goes a long way to reducing consumption and prolonging your filter’s lifespan. On that note, there’s an indicator that lets you know it’s time to change your filter which is a lot easier to read compared to most similar models on the market.
