TAPP 2 Independent Lab Test

TAPP 2 removes over 80+ contaminants tested according to NSF standards.

At TAPP Water we believe in radical transparency and rigerous testing of the effectiveness of our products wherever they are used by customers. Therefore we continously test the products to ensure that they live up to our promises and share the results openly.

First of all the filters go through lab tests where contaminants are artifically added, filtered and output is analysed to confirm effectiveness. Secondly we take water samples from customers before and after filtering.

TAPP 2 Independent lab test

Below is a a lab test carried out by Itabe lab in Barcelona, Spain  using a water sample of 2L of TAPP 2 filtered water, as well as 2L of non-filtered tap water. The test shows that TAPP 2 effectively reduces chemicals such as chloride, nitrate, microplastics, fluoride and TTHMs while keeping healthy minerals  like Calcium, Potassium and Magnesium.

Additional tests are available for New York, Los Angeles and London. We will continue to test in other cities over time.

* Total Chlorine is tested separately with strips and a chlorine meter since the chlorine evaporates on the way to the lab.
** Microplastics count is based on Orb Media’s 2017 report concluding that 94% of US Tap Water contains microplastics or anthropogenic (man-made substances). We’ve used the average amount of particles found per gallon. The smallest particles were found to be 2.7 micron but most considerably larger. Therefore our testing has concluded that all microplastics particles found according to this test will be filtered by TAPP 2. 0 particles remain after filtering. The majority of the particles were fibers (98.3%) between 0.1–5 mm in length. The range in Europe was 0 to 13 particles/liter, with an overall mean of 3.8 particles/l. The report also found that bottled water contained even more microplastics. For more information see Original Orb Media Report and peer reviewed analysis of the study in Plos One.
