At TAPP Water we believe in total transparency and rigorous testing of the effectiveness of our products wherever they are used by customers. Therefore we continuously carry out independent water lab tests of the products in accordance with NSF compliance to ensure that they live up to our promise. The results are then shared openly.
First of all, the filters go through lab tests where contaminants are artificially added, filtered and output is analyzed to confirm effectiveness. Secondly, we take water samples from customers throughout the world before and after filtering.
Below is a water lab test carried out by SimpleWater, one of the top water labs in the world, using a sample of TAPP 2 filtered water, as well as of non-filtered tap water. The test shows that TAPP 2 effectively reduces chemicals such as chlorine, chloride, nitrate, heavy metals and TTHMs while keeping healthy minerals like Calcium, Potassium and Magnesium.

Notes:
* Los Angeles, samples taken on July 26, 2018. Analyzed by SimpleWater in Berkley, CA. Additional lab results are also available for New York and Toronto.
** Water samples taken at 4L/min, after letting the water run for 30s. “Before” refers to unfiltered water, and “After” refers to TAPP 2 filtered water.
*** Total Chlorine and Chloramine is tested separately with strips and a chlorine meter since the chlorine evaporates on the way to the lab. As Combined Chlorine and Chloramine is essentially the same the test results are therefore very similar.
**** 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. Therefore 0 particles remain after filtering. The majority of the particles were fibers (98.3%) between 0.1–5 mm in length. The range was 0 to 232 particles/Gallon, with an overall mean of 21 particles/Gallon. 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.
