If you want pure water from your faucet, a filter that attaches directly to it is a great option. You’ll get clean water on demand, and you’ll never have to worry about emptying tanks or pitchers. The only thing you’ll need to decide is which is the right model for your home.
That’s where we come in! Check out our reviews of 10 of the best faucet water filters on the market today. Then check our buying guide for tips on matching the features available to your own needs. When we’re done, you’ll have everything you need to make the right choice.
Brita’s filter system attaches directly to your kitchen faucet and you won’t need any tools to do the job. You’ll be able to install it in a matter of minutes, as long as you have a standard faucet. But if you have a pull-down or spray faucet be warned: this probably won’t fit.
The filter will remove up to sixty different kinds of contaminants, including reducing the taste and odor of chlorine. And it will remove less common pollutants too. These include benzene, asbestos and 99 percent of lead.
But it won’t remove everything. If you’re looking for a filter to reduce total dissolved solids, this won’t be the right one. Consider a reverse osmosis system instead. (But remember that not all total dissolved solids are bad! They include minerals like calcium that are good for you at the right levels.)
One filter can purify up to 100 gallons, depending on the quality of the water going in. That will last around three months for an average household.
Happily, you won’t need to mark the date for a filter change on your calendar! The system comes with an indicator light that turns from green to red when it needs to be replaced. When the time comes, the one-click design makes changing it easy.
You can turn the filter on and off as you wish, and there are three options for water flow. Choose from filtered, unfiltered and unfiltered spray. The latter two mean you won’t have to use up your filter on water for cleaning or washing up.
PUR’s FM-3700 filter is another that will attach direct to your faucet without needing any tools. Click it into place and you’ll be ready to use it in minutes. But just make sure that your faucet will fit – it won’t work with styles that have a non-removable aerator.
The filter here uses activated carbon and ion exchange to remove up to 70 different contaminants. That’s more than any other brand.
But that doesn’t necessarily mean it’s the best filter for your water. This scores high on removing heavy metals, and is certified to remove 99 percent of lead. It’s also good for mercury and certain pesticides. If that’s what your concerned about, it will be a good fit.
A simple on-off lever allows you to switch between filtered and unfiltered water. That means you’ll only need to use up the filter for drinking, cooking or washing food. Use unfiltered water for washing up or other purposes. The filter will last longer – and you’ll get a faster flow of unfiltered water too.
Like the Brita filter, this one will last for around 100 gallons, or about three months. An indicator light will tell you when it needs to be replaced.
One thing to bear in mind is that, despite the chrome finish, the core here is made of plastic. It’s not the most robust, and if it gets knocked about you may find it springs leaks. And don’t try to purify hot water either – it will damage the filter.
If you’re looking for something a bit more resilient, Engdenton’s faucet filter may fit the bill. There’s no plastic here – the housing is made of food-grade 304 stainless steel. You won’t need to worry about cracks causing leaks over time.
As with others, you’ll need a standard faucet. Pull-down, spray, sensor or other interesting designs won’t fit. And if you have a faucet with an external thread, the thread will need to be at least 0.14 inches.
The filter is activated carbon. It will remove sediment like sand and rust, as well as reducing chlorine. So if your water has a chlorine flavor or smell, you’ll really notice the improvement. It won’t, though, reduce total dissolved solids or do much about other pollutants.
It has a much longer life than some other filters. Depending on your water quality and use, you can expect this to treat around 320 gallons of water. If you’re using 37 8.5-ounce cups a day, that means it will last for six months.
You’ll get a decent water flow through the filter here too – around half a gallon a minute. That’s enough to fill eight cups.
Installation is easy, and you won’t need any tools. If you have an aerator on your faucet, you’ll need to remove it first or the filter won’t fit.
If you’re looking for a highly portable filter system, check out this offering from Home Master. With this one, the small filter block sits on the countertop, with an attachment that screws into the faucet.
For a small unit, this is a filter with a very impressive lifespan. It will filter up to 1,500 gallons before needing to be changed. There’s a version specifically for lead where that amount reduces to 750 gallons. In either case, it’s way out in front of most of its competition.
There’s a choice of three filter options. The basic is a carbon block. It will remove up to 99 percent of sediment and rust, chlorine, herbicides, pesticides and volatile organic compounds.
For a little extra, you can choose a catalytic carbon filter that will capture particles down to a micron. It adds chloramines to the list of contaminants it will remove from your water.
And at the top level – though the price difference is small – is what HM calls an “absolute carbon” block. This has media that will remove up to 99 percent of lead. It won’t, though, remove chloramines.
None of these will remove dissolved solids, so minerals like calcium and magnesium will remain.
All the options are made of BPA-free plastic, so they’re light and easy to move around.
Installation is a simple case of unscrewing any aerator and fitting the diverter valve to the faucet head. You’ll need a standard faucet for it to fit.
And you might need to use an adapter – included in the package – if the thread sizes don’t match. Just take care when doing that. The adapters are all plastic, so if you over-tighten them, they’ll split. Finally, connect the tubing to the filter, and you’re ready to go.
JONYJ’s water filter is another that replaces plastic with 304 stainless steel. So if you’re worried about plastic filters cracking and leaking, it’s well worth a look.
You’ll need a conventional faucet for this to fit – so no pull-down, spray or sensor models. And if you have an aerator, it will need to be removed before you can attach the filter.
If you have a standard faucet, you’ll find installation straightforward and tool-free. The system comes with an adapter to deal with external to internal threading. And it also has a universal adapter to allow it to fit faucets between 0.55 and 0.96 inches.
There are two outlets so you can switch easily between filtered and unfiltered water. And even on the filtered setting, you’ll get a decent flow – half a gallon per minute. That’s enough to fill eight 8.5-ounce glasses.
It uses an ultrafiltration membrane to remove chlorine flavors and odors as well as sediment. It will leave in minerals like calcium that are good for your health. But it will also leave in other contaminants. So if you have serious water quality issues it won’t be the right choice.
The filter life compares favorably with many other systems. Each filter is good for around 320 gallons. Exactly how long that will last in your household will, of course, depend on your levels of use. For most, it will last between three and six months.
One thing to bear in mind with this one is that there’s no indicator light to tell you when to change the filter. You’ll either need to estimate your water use or wait for a change in the taste to tell you when it needs replacing.
Waterdrop’s filter is another that will treat around 320 gallons of water before needing to be replaced. It’s made of BPA-free plastic and attaches directly to your faucet. As with the other models on our list, you’ll need a standard faucet for it to fit.
It uses a high quality activated carbon filter to remove particles down to half a micron. That means it will reduce chemicals like chlorine and fluoride, improving taste and odor. It will also remove lead, and sediments like dirt and rust.
It won’t affect total dissolved solids. Any beneficial minerals like calcium and magnesium present in your water will still be there after it’s treated.
A simple switch allows you to change from filtered to unfiltered water as needed. That will allow you to prolong the life of the filter.
You’ll get a decent flow of 0.5 gallons per minute for filtered water. That means you won’t have to wait for ages to fill a kettle, pitcher or water bottle.
The unit has an operating temperature of between 41 and 122 degrees Fahrenheit. It comes with a 30-day money-back guarantee, and a one-year limited warranty covering materials and workmanship.
Overall, this is a great system – but it does have one drawback. There’s no indicator light to tell you when the filter needs to be changed. That means you’ll either have to estimate when you’ve used 320 gallons, or wait for the water flavor to deteriorate.
ESOW’s filter combines seven-layer ultrafiltration and activated carbon. The ultrafiltration system pushes water through a membrane, catching particles down to a tenth of a micron. It will remove sediment like sand and rust, as well as a wide range of pollutants.
You’ll particularly notice the difference if you have water that suffers from a chlorine odor or taste. Any coffee lovers will appreciate the improvement in the flavor of their favorite beverage!
It’s made of 304 stainless steel, so it won’t crack or corrode. And you won’t have to worry about plastics leaching unwanted chemicals into your water.
Make sure it will fit your faucet before you buy. You’ll need a standard round faucet with either an internal or external thread. And if there’s an aerator, you’ll need to remove it in order for the system to fit.
The filter life here is very impressive. It will treat around 1,500 gallons of water before needing to be replaced. That means each filter will last between three and six months, depending on your water quality and use.
Unfortunately, there’s no indicator to show when the filter needs to be changed. So you’ll have to work this out for yourself with a bit of trial and error. After the first couple of changes, you should have a good idea of the frequency needed. There’s no denying, though, that it’s a challenge at the start.
Lelekey’s water filter system is made of solid stainless steel. That means you won’t have to worry about it splitting and leaking. And there’ll be no problems with corrosion either.
The water passes through six different layers to remove impurities. There are a ceramic layer and activated carbon. Below that is maifan medical stone, alkaline and calcium sulfite balls and finally a stainless steel mesh.
Together, they remove up to 60 different contaminants, including 99 percent of any lead that’s present. But this is mainly good at improving taste and odor from chlorine, and getting rid of large particles like rust. It won’t handle serious problems with water quality.
This is another system that needs to be attached to a conventional faucet. There are four different connectors and adapters in the package. It will fit standard faucets with a diameter between 0.55 and 0.94 inches and no longer than 0.78 inches.
A nice touch is that it’s possible to swivel the system through 360 degrees. That allows you to use it as a water fountain if you want to. You’ll get a good flow rate of half a gallon per minute for filtered water. And there’s a switch to move between filtered and unfiltered.
Lelekey recommends washing the filter once a week to improve its life, and changing it once every three months. There’s no indicator light here, so you’ll need to mark the date in the calendar.
DuPont’s water filter comes in either chrome or brushed nickel finish, and it’s a handsome looking thing. It isn’t, though, quite as robust as stainless steel models, and we’ve heard of some issues with leaking.
The system comes with an FMC100 filter. This will capture sediments like rust and dirt. And it will also reduce levels of chlorine, linden, asbestos, benzene, lead, and mercury. You’ll get water that tastes and smells better as a result.
The cartridge housing and media are also treated with an antimicrobial coating to improve the life of the filter. This one will treat about 100 gallons before needing to be changed.
There’s no indicator light, so you’ll need to estimate that for yourself. The water flow will gradually slow as the filter becomes clogged with sediment. And you’ll notice the change in flavor too. It’s not ideal, but after the first couple of filter changes, you’ll have a good idea of how long it will last.
A simple switch at the side allows you to select filtered or unfiltered water. That means you won’t have to run water through the cartridge if you’re washing up or cleaning. And that will prolong its life and save you money.
Included in the package are the faucet mount, one filter, two adapters, two washers and plumbing tape. As with other filter systems of this type, this will only fit a conventional faucet. But as long as that’s what you’ve got, installation is pretty simple.
If you live in an area with hard water, then Hima’s faucet system could be just what you need. It both removes contaminants and reduces limescale.
It uses no fewer than eight layers of filtration to treat your water. There’s ceramic, maifan medical stone, alkaline balls, tourmaline, negative ion spheres, blue multi-function balls and activate alumina balls. The final layer is metal mesh.
It reduces impurities like chlorine and heavy metals, as well as softening the water. The result is better taste and odor. And you won’t have to worry about limescale building up around your faucet.
You’ll need a conventional faucet for it to fit.
You can select from filtered or unfiltered water with a simple switch. That means you won’t have water running through the cartridge except when you need it. And that will prolong its life and save you money.
It will last anywhere between three and six months. The exact period will depend on how much water you filter, and how many impurities it contains. You can maximize the lifespan by removing the filter every two weeks and scrubbing it with fresh sandpaper.
You’ll get a reasonable water pressure through the system too. But watch out if you have high pressure – we’ve heard of issues with it falling off the faucet.
Need some help to decide which is the best faucet water filter for your home? Read on, and we’ll take you through the questions to ask yourself before you make your final decision.
What contaminants do you need to remove?
Faucet water filters are particularly good at dealing with flavors and odors from chlorine. So if that’s your problem, most of the models on this list will work well.
Some are also good at capturing sediment like sand or rust. And the Hima filter will also reduce limescale.
If there’s an issue with lead in your water, look for a filter with specific lead-attracting media. You may find you need to compromise on removal of other substances. With the Home Master filter options, for example, you’ll need to choose between removing chloramines and lead.
And be realistic about what a filter of this kind can achieve. If you have specific water quality issues – sulfur, for example – they won’t be effective. You’ll need to invest in more expensive solutions, like reverse osmosis, to tackle this kind of problem.
How much maintenance are you prepared to do?
With some filter systems, you’re encouraged to clean the filter to extend its life. That means more work.
And the lifespan of different filters can vary dramatically. The ones on our list will treat anything from 100 to 1,500 gallons before needing to be replaced. Replacement is usually simple enough, but it’s another chore.
And remember to take into account the cost of new filters when you consider your budget. Smaller filters are usually – though not always – less expensive. But it may be a false economy if they don’t last as long.
Some models have indicator lights to tell you when the filter needs to be changed. For us, that’s a major bonus. It takes the guesswork out of replacement schedules, and means you won’t replace your filter before you need to.
Stainless steel versus plastic
The filters on our list have either stainless steel or plastic bodies. Generally speaking, stainless steel is better. It won’t corrode or split. You shouldn’t find it starts to leak over time as a result. And you won’t have to worry about chemicals leaching into your water.
Plastic filters, on the other hand, are lighter and usually easy to install. And they’re often less expensive upfront. Bear in mind, though, that you may find you need to replace them sooner if they split.
It’s worth mentioning that most plastic filters are BPA-free, so chemical leaching may be less of a concern. But remember that BPA isn’t the only substance that can cause problems. Other types of plastic may not have undergone rigorous testing to determine whether they can leach into water too.
Ready for pure water straight from your tap?
We hope you’ve enjoyed our reviews of some of the best faucet water filters out there! You’re now one step closer to choosing the right filter for your needs.
Our top pick is the FM-3700 from PUR. It removes a wide range of contaminants, including virtually all lead. And the handy indicator light takes the guesswork out of knowing when to replace the filter.
And if you prefer a filter with a stainless steel body, we like Engdenton’s model. It’s well-built and the filters are long-lasting too.
Whichever filter you choose, we hope you’re soon enjoying better tasting, purer water. Happy shopping!
