TAPP Water filter performance
by independent laboratory tests.
How do I know that TAPP Water filters really do what they promise?
Here you will find an overview of the TAPP Water water filters as well as research results and independent laboratory tests.
What filter our water filter?
Based on our tests and research, TAPP Water removes more than 80 potential substances from tap water and reduces more than 30 others. Here is an overview of the filters and the reduction efficiency.
The unpleasant taste or smell of water is generally caused by chlorine, its by-products, and organic impurities. >95%
Chlorine is added to disinfect tap water from harmful viruses and bacteria. >95%
Over 100 by-products including 32 known chlorine by-products (VOC) such as THMs identified as potentially cancerous. >95%
Plastic parts with a length of a few micrometers. >95%
Occur naturally or through pipe corrosion, e.g. lead, zinc, manganese, copper,… >90%
14 listed pesticides including chlordane, heptachlor and lindane. >95%
12 herbicides listed, including 2,4-D and atrazine. >95%
Generally caused by fertilizers. In contrast to nitrates, nitrites are found in very low concentrations in water. > 70%
Medicines were found in very low concentrations in tap water. This includes e.g. atenolol, carbamazepina, estrone, meprobamate and trimethoprim. > 90%
This includes PFOA, PFOS and PFNA. > 90%
Most “bad” bacteria, including E. Coli, as well as microbial cysts, including Giardia and Cryptosporidium. >90%
The turbidity is a measure of the extent to which the water loses its transparency due to the presence of suspended particles. >90%
What does TAPP Water not filter?
A common misconception is that a water filter should remove everything from tap water. Here is a list of the substances and parameters that TAPP Water does not remove or reduce and why.
TDS are basically minerals like inorganic salts and small amounts of organic matter dissolved in water. These are usually calcium, magnesium, sodium, potassium, carbonate, bicarbonate, chloride, sulfate, and nitrates. Most lab reports use electrical conductivity instead of TDS. In no case does TDS indicate whether the water is potable or not.
Minerals are calcium, potassium, magnesium, chloride, etc. that people need to survive. These essential minerals are insignificantly reduced by carbon blocks.
Hard water (called on lime) is water with a high concentration of calcium and magnesium. Hard water is usually an advantage for drinking purposes. However, limescale builds up, which is often perceived as a problem.
The pH value is a measure of the acidity or alkalinity of water. A pH of 6.5-8.5 is considered normal and your body adjusts the pH to the normal state of the body (blood = pH 7.4) after drinking. There is no known health risk related to pH within the legal range.
Independent laboratory tests to confirm that the filter is working.
Every year we conduct laboratory tests with third party laboratories. Here is an overview of one of these tests, carried out by SimpleWater, one of the most famous laboratories in the world, in Los Angeles, USA, in the period 2018-2019 *. The link below the table has the full list of substances with external sources by the laboratory to verify the claims.
|Total chlorine (ppm)||0.8 => 0.05 = 95%|
|Chloramine (ppm)||0.8 => 0.05 = 95%|
|pH||7.8 => 7.9|
|Water turbidity (NTU)||0.17 => 0.0 = 100%|
|Microplastic (particles / liter)||29 => 0.0 = 100%|
|Nitrate & nitrite (ppm)||0.22 => 0.0 = 100%|
|Heavy metals (average of all), (ppm)||0.15 => 0.0 = 100%|
|By-products of chlorine disinfection, (pbb)||6 => 0.0 = 100%|
