Thinking about buying a faucet water filter? What makes TAPP 2 so special compared to other products? Who is it for, what does it filter and how does it work?
What is TAPP 2?
TAPP 2 is faucet water filter using coconut shell carbon block technology for better tasting and clean water removing over 80+ known contaminants. Each refill lasts up to 3 months.
What problems will TAPP 2 solve for you?
- Your tap water tastes bad/poorly due to chlorination, chloramination or other content in the tap water
- Your tap water may be contaminated / contain pollutants from old pipes (lead, copper, etc) and other issues with the public tap water source (nitrates, microplastics, PFAS, etc)*
- You want to remove contaminants but keep healthy minerals in the tap water
* Recommended for households with municipal tap water that is officially reported as drinkable / potable
We do not recommend TAPP 2 for
- Badly contaminated tap water (especially bacteria and viruses)
- Softening of hard water as it’s not a water softening filter
If you have such problems then visit our water filter guide.
How do I know that TAPP 2 works?
To learn more about water filters in general, read our article about how water filters work.
The reasons you can be confident that TAPP 2 faucet water filters specifically work are:
- TAPP 2 uses proven filtration technology (Activated Carbon) tested and certified by EPA, NSF, WHO to remove the listed contaminants
- TAPP 2 is independently tested in the EU and US accordance with NSF testing criteria
- The TAPP 2 carbon block has been tested in accordance with NSF 42 and 53
What are the benefits of TAPP 2 vs bottled water?
Affordable: Filtered tap water is over a hundred times cheaper than bottled water. Average households can save $300 USD per year using TAPP 2. See cost calculator.
Convenient: Filtered water right out of the tap. Puts an end to carrying heavy water bottles, or having to wait for a pitcher to fill.
Easy to use: Installs in under a minute, without tools or a plumber.
Cleaner water: Filters microplastics and hormones commonly found in bottled water. Independently certified water filtering technology.
Reduces plastic waste: Good for the environment as it reduces plastic waste and CO2.
A detailed comparison shows that TAPP 2 filtered water is as healthy or healthier than bottled water.
What are the benefits of TAPP 2 vs other water filters?
Always clean tasty water: Comes with an Automatic Water Filter Replacement service
Superior filtering technology: TAPP 2 filters 80+ contaminants including chlorine, microplastics and lead.
Healthy Minerals: TAPP 2 keeps the healthy minerals including magnesium, potassium and calcium
Sustainable: TAPP 2 refills use recyclable materials which can be disposed of plastic and organic waste. The device itself (without the refills) is made out of recyclable ABS.
Connected: The free iOS and Android MyTAPP apps, monitor the current state of your filter cartridge, alerts when it needs to be replaced and keeps track of savings, bottles eliminated and CO2 reduction
Compatible: Adapters provided free of charge to connect to 98% of standard faucets (See specs below).
Value for money: In comparison with other faucet and pitcher filters TAPP delivers more clean water for less

What does TAPP 2 faucet water filter remove?
Want healthy and fresh tap water? TAPP 2 removes over 80 contaminants, effectively reduces another 30 and moderately another 22. This includes Chlorine, heavy metals such as Lead, Cancerous bi-products from chlorine (VOCs), Microplastics, pesticides, petrochemical, most pharmaceuticals and more.
Note: Does not remove healthy minerals such as magnesium, potassium and iron, which are important nutrients for our well being.
The carbon block technology used in TAPP 2 is highly effective at water treatment. It has immense surface area. A single pound of powdered activated carbon has a filtering surface area equivalent to 125 acres. It is the best known treatment for organic chemicals, VOCs, pesticides, herbicides, and chlorine and its by-products. It is also an unchallenged taste-and-odor improver and provides very high quality particulate filtration, down to 2-microns.
TAPP 2 removes chemicals by the process of adsorption (as opposed to absorption). Carbon attracts certain chemicals at the molecular level much in the way that a magnet attracts and holds metal filings. When the surfaces are full, the filter must be discarded.
This includes the following main categories:
- Organoleptic
- Bad odor
- Bad taste
Removes 80+ contaminants:
- 95% lead removal (NSF-53)
- 95% of copper
- 95% of free chlorine
- 90% chloride reduction
- 90% PFOA
- 90% PFOS
- 90% PFNA
- 90% of Pharmaceuticals
- 100% of Microplastics
- Petrochemical products
- Trichloroethylene (TCE)
- Tetrachloroethene (PCE)
- 32 known chlorine by-products (VOCs) such as THMs identified as potentially cancerous
- 14 listed pesticides including Chlordane, Heptachlor, and Lindane
- 12 listed herbicides including 2,4-D, Atrazine
Reduces 30+ contaminants:
- 70% of heavy metals such as mercury
- 70% of nitrates
- 30-70% Arsenic and Asbestos
- Sodium
- Calcium (Limescale)
- Fluoride
- Microbial cyst including giardia and cryptosporidium
- Bacteria & Viruses

Testing & Certifications
The TAPP 2 carbon blocks have been independently tested in accordance to NSF-42 and NSF-53. In addition to this we’ve performed multiple independent lab tests in Europe and North America for the products.
How does the TAPP 2 recyclable cartridges work?
TAPP 2 refill cartridges are made out of recyclable ABS plastic, coconut based activated carbon and other non-toxic materials which remain inert after decomposing. The cartridges can be separated so that the plastic can be recycled and the carbon block is inert and will break down on a landfill without any plastic residues.
Note, that the device itself (without the refills) is made out of highly recyclable ABS polymers, and can be disposed of with plastic waste.
