Tap Water Filter Technology


TAPP 2 Twist

TAPP 2 cartridges can last up to 3 months maximum. When starting to use a new cartridge, set the date on Twist to be: date = today + 3 months. Three months from now, when you reach that date, the visual cue will remind you to change refill.

TAPP 2 Cartridges

TAPP 2 refill cartridges are entirely made out of non-toxic materials which remain inert after decomposing. The cartridges contain a high percentage of biodegradable and compostable material and can be disposed of with organic waste. This organic waste ends up in an industrial composting plant where the cartridge breaks down within 1-2 months. Alternatively, it can be discarded with general waste, where it will break down within a couple of years in a landfill or be burned without causing any plastic residue. It will also take a couple of years to break down in a garden compost, so not recommended.

Note, that the device itself (without the refills) is made out of highly recyclable ABS polymers, and can be disposed of with plastic waste.

TAPP 2 filters are tested to effectively absorb chemicals of between 1200-1500 liters of water (depending on original water quality) or 2-3 months of water usage for an average household. We cannot ensure water is microbiologically safe after 3 months since the first use. Even if they are not used frequently as the filter will lose its adsorption capability over time if not replaced and thus no longer remove chemicals, bad taste and odor.

The lifetime of the filter cartridge depends on your water consumption as well as on the quality of the filtered tap water. In an average household of 3-4 people, the cartridge will last about three months. In order to ensure the longest possible lifespan of the cartridge, please avoid running hot (> 100ºF) or high-pressure water through the cartridge/filter part of the device. Also, it is important not to use the cartridge for more than 3 months as there is a risk of bacteria accumulating inside the carbon block.

Contaminants TAPP 2 remove

TAPP 2 reduces Chlorine by 95% or more based on 100s of tests carried out on tap water around the world. This improves the taste instantly for chlorinated water. In addition to this TAPP 2 removes all know bi-products from Chlorine (whereof some cancergenic such as THMs).

Yes, TAPP 2 reduces Chloramine by 95% or more based on more than 50 tests carried out on tap water in LA and other cities using chloramine rather than Chlorine. In addition to this Amonia was reduced by 90% or more.

Calcium is considered a mineral with health benefits and not a contaminant. Unfortunately calcium also has the unfortunate bi-effect of causing limescale in combination with magnesium carbonates. The standard TAPP 2 filter only marginally reduces calcium and can therefore not be considered effective in limescale removal. TAPP Water will however launch a separate cartridge for limescale removal by the summer of 2019. Sign up for our newsletter to find out more.

Yes, TAPP 2 removes all microplastics that have been found so far in tap water thanks to the 1-2 micron carbon block.

Yes, TAPP 2 reduces Nitrate by 90% or more based on independent lab tests.

Yes, TAPP 2 reduces Nitrate by 90% or more based on independent lab tests.

TAPP 2 reduces fluoride by 30-70% based on independent lab tests. Fluoride is a natural compound found most fresh water sources, tea, vegetables and fruit. It’s not considered a contaminant although we are aware that some people are concerned about the health effects. Many water filters claim fluoride removal but in reality we’ve found that reverse osmosis is the only effective way to reduce fluoride by 95% or more.

TAPP 2 is not certified for arsenic removal but in the tests where arsenic was detected before filtering more than 70% was removed. The maximum concentration level recommended by EPA and WHO is 10 mg/l. Therefore the results mean that for any tap water with 50 mg/l or higher concentration of arsenic alternative solutions should be considered.

Yes. Based on tests performed on the type of activated carbon block used in TAPP 2 pharmaceuticals are reduced by 95% or more. This includes: Hormones: prednisone, prednisolone, progesterone, testosterone and cortisol Antibiotics: ciprofloxacin, used to prevent certain infections caused by bacteria, as well as sulfamethoxazole and trimethoprim, which are used to treat a wide variety of bacterial infections including pneumonia, and urinary tract and intestinal infections Antidepressants: fluoxetine, prescribed to treat a variety of conditions, including depression and other mental/mood disorders Anti-anxiety medication: meprobamate, a treatment used to relieve nervousness or tension that exceeds stress of everyday life Painkillers: ibuprofen and naproxen Additional tests will be performed during 2019 to confirm these results.

Yes, TAPP 2 is tested for lead reduction and removal in accordance with NSF 61. This means lead is reduced by 95% or more. Read more here: https://pre.tappwater.co/us/how-to-remove-lead-from-tap-water/
