So you’re interested in finding the best faucet water filter? We tested over 30 available water filters on faucet before we started TAPP Water. Recently we tested them again and here’s a short summary of how we identified the best faucet filters.
Why do you need a filter?
Before anything else, you need to answer this question. Our initial focus was Europe and North America, where about 99% of the population has access to drinkable clean tap water today. This means that the main reasons for needing a water filter generally are:
- Improve the taste of the water by removing chlorine, water hardness and other elements that contribute to poor taste and odor.
- Protect from possible contaminants leeching from pipes such as lead, copper
- Reduce risks of contaminants found in public tap water including pesticides, nitrate, microplastics, PFAS, chlorine bi-products (e.g. THMs – trihalomethanes).
There are other water issues specifically to households with well water such as ecoli, chromium, arsenic and uranium. Well water should always be tested before you chose a water filter.
What kind of water filter?
For 95% of households, a point of use filters such as a carafe or faucet filter is sufficient. These are much more affordable and easier to install than under-the-sink and whole house filtration systems. They usually use granular activated carbon or carbon blocks, sometimes combined with other filtering technologies such as ion exchange or ulfra-filtration.
Pitcher and Carafe filters
Although this blog is about the best faucet water filters it’s worth exploring the carafe filters first.
Brita is the leader in carafe filters since 20 years back. The carafe filters and their competitors use activated carbon sometimes including ion-exchange.
Through surveys of over 500 users and testing we found the following pros and cons of carafe filters.
- Provide reliable filtering of tap water
- Improve taste
- No installation required
- Water still tastes chlorinated
- Take up a lot of space in the kitchen or fridge
- Slow to filter water (about 0.25 gal/min)
- Ugly design
- Easy to forget to replace filters
I conclusion carafe filters are a good alternative to replace bottled water and reduce risk of tap water contaminants. But they are not the best alternative.

The best faucet filters
Faucet water filters have existed for 20+ years originally launched by PUR and Culligan in North America.
Similarly to carafes, these generally use activated carbon which is effective in removing chlorine and most common contaminants in drinking water. The difference, however, is that they are attached to the faucet which means that you can fill up a glass of water almost instantly.
The concept is great so why doesn’t everyone have one?
What we found was that most existing faucet filters either had problems with leakage, didn’t fit, didn’t last very long or were perceived as ugly. In addition to this the testing was limited to NSF in a lab.
This is why we created TAPP 2 as the ultimate faucet filter. We looked at all the issues with existing faucets filters and worked with a team of amazing designers, product engineers, water specialists, manufacturers and software developers to make it much better.
We also tested the filters with independent labs in cities throughout the world.
This is what customers say they like and dislike about TAPP:
- Fresh tasty water directly from the tap with the touch of a switch
- Long lasting (3 months and 400 Gallons of water)
- Easy and fast to install
- Automatic reminders when they need to be replaced
- Great design and minimum issues with leakage
- Affordable ($5 per month) with replacements sent automatically
- Doesn’t fit with the design of an expensive design kitchens
- Won’t fit shower faucets and a few other design faucets

Note: For search people often refer to faucet water filters as best water filter faucet or best water filter on sink.
Other water filters
If the tap water in your area is not safe to drink, then you need to consider a combination of other technologies such as Ion Exchange, Reverse Osmosis and Ultra Light. Usually, these are provided as under the sink filters or whole house filters and require a professional plumber to install them and do the maintenance. Our research showed that most users of these filters didn’t really need them and found them expensive to install and maintain. In addition to this, reverse osmosis in particular wastes a lot of water and energy in the filtration process.
