Water – it’s a basic human right that you should have access to it. Ah, but if only the right was to fresh, crystal clear, bottled water.
And what passes through your tap faucet usually contains more than just water. Besides chlorine and other chemicals used to keep your water clean, you might also find lead, mercury and even asbestos lingering around. Sometimes it’s contaminated at the source, other times it’s just the result of aging pipework.
Whatever the reason, filtering your water is a simple, cost-effective and easy solution. In fact, the hardest part of filtering water is choosing the best faucet water filter.
Below we have reviewed the most efficient and effective filters for your consideration.
Best Tap Water Faucet Filters Comparison
Best Faucet Water Filter Reviews
1. PUR Advanced FM-3700B Faucet Water Filter System
- 2 x 7.3 x 7.7 inches
- 100 gallons (454 liters) capacity
- 15 pounds
- Chrome finish
- In the box: 1 PUR unit, filter, filter casing, auto safety management gauge, 4 faucet attachments.
Doesn’t it just look the part?
Yes, it’s plastic. Other than that, we’ve struggled to find a fault with this water filter. It’s a decent size and weight that doesn’t put a strain on your faucet but can still handle a fairly high water pressure and volume. It’s also quite easy to attach with the faucet attachments – essential if your faucet has an internal thread, rather than external.
The filter is a PUR Mineral Filter 100-gallon capacity activated carbon filter that can sift out over 70 different contaminants from your water. This includes removing 99% of lead, 96% of mercury, asbestos, other hard metals, and minerals, as well as chlorine. The result is a very clean, pure tasting and smelling water that’s instantly accessible from the tap.
We had no trouble with leaks, weak plastic parts, or wear and tear when installing or testing the filter. Should anything break, it’s good to know you have 2 years warranty. It also has 1-click installation, which means that once you’ve got it set up and screwed onto the faucet, you can remove the bulk of the filter with one click. It frees up sink space in under a second.
There’s also a 360 swivel built into the faucet filter so you can adjust it, move it out of the way and angle it as you desire.
We highly recommend this filter for use in the kitchen and bathroom sinks. It’s very good at producing clear, cleansed and odorless water that’s perfect for drinking, cooking, washing the dishes, brushing your teeth and pretty much anything else!
It’s sturdy enough to handle high volumes of water although you may need to replace the filters slightly more often due to the 100-gallon capacity. But consider how well built this filter is, we believe it will last far longer than many other filters on the market, and thus offers a long-term cost saving.
2. Waterdrop Water Faucet Filtration System
- 1 x 7.1 x 2.9 inches
- 320 gallons (1454 liters) capacity
- 85 pounds
- In the box: Waterdrop unit, filter, faucet attachments.
The Waterdrop faucet filter looks the part and delivers, with a 30-day money back guarantee if you’re not satisfied. It has a 320-gallon capacity filter, that can last you up to 6 months, depending on your water usage. The activated carbon fiber inhibits bacteria, reduces contaminants (chlorine, lead, other metals etc.) and sediment. It’s also pretty effective at keeping your water odorless and pure flavored.
For removing total dissolved solids, however, you will need a reverse osmosis filter.
It’s a sleek, white shiny filter – not as nice as stainless-steel but still very sturdy and quite modern in appearance. Like nearly all other filters on this list, you can only use this with cold water. We found the pressure of the water it exerted was near the same as the faucet without a filter attached, which was quite impressive too.
Currently, the biggest fault we can find is the minimal 1-year limited warranty: most other filters come with 2 years at least. However, given the sturdy build, ease of use and quality of water provided, we doubt you’ll be returning it any time soon.
3. Brita On Tap Faucet Water Filter System
- 5 x 6.3 x 9.8 inches
- 100 gallons (454 liters) capacity
- 66 pounds
- In the box: Brita unit, 1 filter, faucet adaptors.
The standout feature of this model is the 3 spray settings. Filtered, unfiltered and unfiltered spray – very similar to the Jetery faucet water filter. The Brita filters out over 60 different contaminants, including 99% of lead, chlorine, benzene, and asbestos for fresh, clean tasting water that’s completely odorless.
Regarding aesthetics, it’s a bit of a letdown, but it’s not unattractive. The white plastic feels sturdy and strong, plus replacing the filters is simple. If your faucet has an external thread, you can attach it directly onto the tap rather than using an adaptor, which simplifies the installation further.
According to Brita, 1 filter will be effective for 100 gallons – or 4 months. This doesn’t really add up, with nearly all other filters needing 200-gallon capacity filters changed after 2 or 3 months. Brita filters are also not the cheapest – which could explain it. Perhaps these filters are somehow a higher quality?
From our review, our water tasted cleaner and fresher but, in a water test, the results weren’t any better than the other filters on this list.
4. Culligan FM-25 Faucet Water Filter
- 5 x 3.5 x 6.5 inches
- 200 gallons (909 liters) capacity
- 85 pounds
- Chrome finish
- In the box: Culligan unit, 1 filter, faucet adaptors.
A very nice filter to use, especially on small faucets and sinks with little room for bulky chambers and switches. The chrome finish, plastic filter from Culligan is possibly one of the simplest to install and also the sturdiest: rather than hanging off the faucet, this filter sits neatly in front of it.
It uses a carbon block filter to remove chlorine, odors, flavors, lead and other potential contaminants and sediments from your water. Culligan designed this filter especially to eliminate odors and tastes from water for a clean drinking experience.
These filters are very easy to find online – you can bulk buy them from Amazon if needed. The filter needs replacing every 2 months, which is quite often when compared to other 200-gallon capacity filters.
The ‘diverter tab’ allows you to switch from filtered to unfiltered water – a good, standard feature. Although it looks very shiny and sturdy, it is in fact made of the same plastic as the shell of the filter unit. We could envisage it snapping off with heavy use.
5. Jetery Faucet Water Filter System
- 4 x 5.6 x 3 inches
- 320 gallons (1454 liters)
- 05 pounds
- BPA-free plastic
- In the box: Jetery unit, 1 filter, faucet adaptors, spare parts.
It looks smooth and modern… and tastes smooth and modern. This is a reliable activated carbon fiber filter that fits nearly all standard faucets and comes with 3 different water settings. Filtered water runs the tap water through the filter and out of the side, save water runs your unfiltered tap water out in a fanned, shower-head style way, and regular tap water with your usual flow rate.
This faucet filter makes the list for its water-saving additional setting, ease of use and long-lasting filter that only needs changing twice a year.
It is made of shiny white plastic – but it is BPA free and it doesn’t feel cheap or flimsy in the slightest. Jetery provide a few spare parts in the box too, although we didn’t see any reason why you would need them. It feels sturdy and we couldn’t identify any components that would wear away or leak over time.
Jetery’s filter is very much focused around health, providing pure and clean water for you and your family. Although it won’t remove total dissolved solids, it will remove chlorine, sediment and other contaminants that are polluting your water.
6. Culligan FM-100-C Faucet Mount Water Filter
- 5 x 5.2 x 3.1 inches
- 200 gallons (909 liters) capacity
- 1 pound
- Chrome finish
- Plastic with metal components
- In the box: 1 Culligan unit, 1 filter, 1 faucet adaptor kit, 1 lithium battery (pre-installed), manual guide.
Once you get past the 90s UFO vibe, this is a simple yet efficient water filter. It’s granular activated carbon fiber filter effectively removes chlorine, heavy metals (lead etc.), sediments and unpleasant water tastes and odors. You can also switch between filtered and non-filtered tap water by flicking a switch, rather than dismantling the filter from the faucet.
Although it comes with a battery, we’re happy to report it’s not essential for filtering your water. The battery powers the tiny light that will flash when your filter needs changing – it’s useful if you’re always forgetting to change the filter every 3 months, but it’s also good to know that if the battery dies you don’t have to frantically search around for a spare battery before you can fill a glass with filtered water.
The price is very similar to other, stainless-steel filters on this list – yet the Culligan is made of plastic with a chrome finish. It feels cheaper, but with the light to indicate a filter change, we felt it deserved a slightly higher place on our list!
7. Wingsol Faucet Water Filter System
- 3 x 2.8 x 5.1 inches
- 200 gallons (909 liters) capacity
- 1 pounds
- Silver steel
- Food-grade stainless-steel
- In the box: Wingsol unit, 1 five stage filter, 2 faucet adaptors.
Visually, you’d think this faucet filter is the same as the Engdenton filter we reviewed. In fact, at the time of writing there’s only 1 cent price difference between the two… but it’s what’s on the inside that counts. The filter. These 2 brands use different filters and that does make a difference!
The Wingsol 5 stage filter removes all sediment and reduces levels of chlorine, lead and other metals/chemicals. A ceramic filter, pre-GAC, KDF, MicroNose, and post-GAC are all packed into one. This will remove bacteria, like salmonella, as well as odors, heavy metals and chlorine flavors from your water. When this filter needs changing (3-month rotation) it will visually look dirty. We found that quite satisfying to see the filter working!
It’s slightly more effective than the Engdenton and that’s why it’s landed one place higher on our list.
Replacing this filter is easy – you can buy them directly from Amazon. As for style and design of the filter, it’s easy to attach if you have a conventional faucet and easy to maneuver with 360 adjustments. Just like the Engdenton, you have a switch to go back to tap water.
8. Engdenton Faucet Water Filter
- 4 x 6.8 x 3.1 inches
- 320 gallons (1454 liters) capacity
- 65 pounds
- Silver steel
- Food-grade stainless-steel
- In the box: 1 Engdenton unit, 1 filter, 2 faucet adaptors.
The key features of this simple filter are useful and effective. Once attached, you can swivel the tank-like filter 360 degrees and even angle it upwards like a water fountain. You can also flick the switch to alternate between water coming out of the filter and unfiltered water coming out of the tap.
The size and off-side placement of this filter on the faucet makes it awkward for small sinks, however. It works best with external thread faucets but can be adapted for internal threads.
It contains an activated carbon filter to filter many sediment contaminants, inhibit bacteria and improve the taste of your water. This is great for removing chlorine but can’t filter total dissolved solids in water, e.g. calcium and other minerals.
Finding replacement filters is not easy for this model – you can either search online (we eventually found compatible ones on eBay) or try contacting Engdenton. But at least they’re effective and super long lasting! Engderton suggest their 320-gallon capacity filter will last 6 months, but for infrequent use, we felt it would last longer.
9. PUR FM-200B Faucet Water Filter
- 3 x 3.2 x 7.8 inches
- 100 gallons (378 liters) capacity
- 05 pounds
- Black color
A small, cheap and cheerful filter. It’s quite bulky on your faucet but it’s not unattractive to look at. The outer material is a black shiny plastic – not very sturdy. Most of the components, including the adaptors, are made of the same cheap plastic. It’s not going to survive a drop off the counter.
It’s quite slow to filter water and you get quite a small stream. We felt wary about forcing more water through due to the poor-quality plastic. It can’t be used with hot water.
The filters (effective at filtering 70 contaminants plus chlorine) cost more than half what the unit itself costs. Considering the cost of the unit includes 1 filter, that puts the real price of the unit itself at just over $7 currently. Replace filters every 3 months.
There are 4 adaptors included for external and internal threaded faucets – but if none will fit you can contact PUR for a free adaptor that fits your faucet. You also have 2 years warranty.
It’s perfect for an occasional glass of water, but not practical for heavy everyday use.
How to Choose a Tap Faucet Water Filter
Ideally, you should start searching for a filter when you have your priorities figured out. What kind of water filter do you want? Read through these essential things to look out for to get an idea.
First look at the brand – well-known brands tend to have a better warranty, customer support and a reputation to uphold. But that’s not to say lesser known brands are not always as good. We find it’s better to ignore the name on the filter and focus on: the quality of materials used, the filter types and how effective they are, and most importantly whether it’s compatible with your faucet.
There’s not much worse than spending hours researching a water faucet only to realize it will never be compatible with your faucet.
Some will make your water taste better than others. If you’ve got strange tasting/smelling water, go for filters that are more thorough. Those that just remove larger sediments might leave the strange taste in your water. If your water tastes fine and you’re just concerned about contaminants, you’ll have more choice across the water filter market.
They vary drastically in price. Always check the cost of replacement filters along with the cost of the unit itself, plus the warranty you’ve got and what it covers. This will give you a better idea of long-term costs. If a filter is considerably cheaper, find out why. Do they compromise on quality materials, or do they have less effective filters? If the filter is still effective, but the unit is made of cheap plastic, that would be perfect for an infrequently used faucet but cause some troubles for a large household frequently used the faucet.
How much water can fit in the filter, how much can it process before you need to change the filters, and how much water can the pipes handle? You’ll notice on some off-set filters that the plastic tubes connecting the filter to the faucet are a lot smaller than the original water pipework – this reduces your water capacity. You might notice a smaller stream of water from your faucet. Choose a system that can handle your water capacity needs. For a small glass of water every now and then, a low capacity system is fine. For frequent use as you’re washing the dishes, preparing dinner, washing your hands etc. a more capable filter will be needed.
There are 2 main types:
Carbon filter – removes all impurities including odors and weird tastes as the water is pushed through. These are great for removing large sediment and even small contaminants. You’d expect all quality direct flow filters to be using a carbon filter.
Reverse osmosis filter – combining a carbon filter with a thin acetate filter to pressure the water as it’s purified. This will remove more contaminants than just a carbon filter alone, but it is more expensive and takes up more space under the sink. With a good carbon filter, the extra contaminants removed will be minimal anyway.
Installation and Maintenance
We’ve got some tips on this below. Even if you have no DIY experience, most people could install a water filter by following the guide or checking out a YouTube video… but sometimes you will need a drill. If you can’t install the system by yourself, it’s better to avoid a fixed side offset faucet filter. Yes, you can hire a man in to install it, but rehiring someone to change the filters and maintain it every month is expensive. Consider your own capabilities before choosing a complex system!
Types of Tap Faucet Water Filters
There are 2 main types that you’ll come across:
- Direct flow – this is a filter that fits onto the end of the faucet. Water runs through your pipes, through the filter and out of the faucet. It’s cheap and efficient but will need replacing regularly.
- Side offset flow – these are much more common and more permanent. These attach indirectly onto the faucet. Water is directed from the pipe into the filter system before coming back through and out of the faucet. These are more expensive but also more reliable and can handle much more water before you need to replace the filters.
Side offset is bigger – but not necessarily better. Size does matter! Having a small, direct flow filter in a faucet that’s used heavily is as inefficient as having a large and complicated side offset flow filter installed in an RV that you only use once a year for a few liters of water.
Direct flow filters are more cost effective and useful for small homes and faucets that don’t get a lot of use. Side offset flow filters are more cost effective for larger homes and faucets that are used regularly with constant water flow.
Do You Need a Tap Faucet Water Filter?
The biggest motivator people have for getting a tap faucet water filter, is when they take a big gulp of fresh water from the tap… and it just tastes wrong.
Whether it’s a chlorine taste, strange odor, or just the thought of contaminants putting you off, the solution is to purify your water straight from the tap.
By purifying, we mean filtering. Unlike a fitted, under-the-counter filter, those that are clipped directly onto the tap faucet are smaller and don’t have space for a large, reverse osmosis system.
But they are still very effective at filtering out sediment, toxins, lead, drug residues and a whole range of other impurities we’d rather not drink.
Other benefits include convenience and money savings – is so much easier to pour a glass of water from the tap instead of buying bottled water. Less plastic water bottles are better for the environment too – if that’s something you care about.
It’s not completely hassle-free, as you’ll need to change the filters at some point or another, but it is easy to install even for dummies (all of our reviewed filters were installed by us, so we really do know how easy some are).
The ease of use, potential health benefits from drinking purified water from home and just great tasting water you can enjoy, make the effort worth it.
Even if you don’t have a strange taste or odor to your water, you can still notice a difference once you’ve attached the tap filter. Whether it just feels softer when you wash your hands or makes cooking/baking that little bit smoother.
Ideally, anyone living in an area where the mains water could potentially be contaminated (or the governing water body is adding excess chemicals to sterilize it) should have a water filter installed. This extends from homes to apartments, RVs, restaurants, outdoor water fountains and even backyard faucet taps if your pets are drinking from them.
Faucet Water Filter Quick Installation Tips
Direct flow faucet filters are usually as simple as clipping the filter onto the end of the faucet with a faucet adaptor… side offset flow is a bit more complex. Follow these tips!
- Don’t drill until you need to. Some guides require that you drill into your sink to create a new hole for a tap faucet that comes with the water filter. Others just attach to the existing faucet, so your filtered water runs out of your usual faucet.
- Connect the right tubes! If it’s not clearly marked on the filter system where the water goes in and where the water comes out, carefully check the manual. You really don’t want to connect it up backward. Trust us.
- Empty the pipes before you start detaching them for the water filter. Under the sink, or in a maintenance cupboard, you should be able to turn the water supply off. Then turn the sink faucet on and you’ll drain out any water that’s lingering in the pipework.
- Once all your tubes are attached, place the filter in an accessible location under the sink. Make sure the tubes are long enough that you can comfortably move the system to change the filters when you need to.
Faucet Water Filters Maintenance
This is something you need to maintain – but it’s simple. Honestly, looking after a goldfish is more time consuming than some of our recommended faucet water filters.
The main thing you need to worry about is when the filters need replacing. Some manufacturers will give a time estimate, e.g. every 2 months, but in our experience, it’s more accurate to go by how much water you use. Someone using the tap every day will wear out the filters quicker than a tap that’s used infrequently.
If your sink filter system doesn’t have sensors to tell you when the filters are clogged up or worn out, keep an eye on the water flow. It will take longer for the water to filter through, leaving you with a noticeably slower trickle pace.
If you’re noticing problems that aren’t fixed by changing the filter, check the manual for a solution and your warranty details. It might be something as simple as detaching the tubes and flushing them through or tightening your direct filter around the faucet.
If you don’t maintain and change the filters, there’s not really any point in having the system attached. After those filters are worn, you’ll be back to your unpurified, potentially contaminated water again.
Just set an alarm or reminder to check the system once a month. For goldfishes, we recommend daily care, just FYI.
