fILTERED WATER ANALYSIS

All TAPP Water products are independently tested and certified.

Choosing the right water filter can be hard. How do you know that the water filter actually works?

The first step is to ensure that the water filter you are planning to buy is tested and certified by accredited labs.

TAPP Water is the only faucet water filter provider that openly shares all lab results and certifications for customers to view.

Before you continue reading below learn about the most common tap water contaminants.

 

Independent lab tests of Essential (TAPP 1), EcoPro (TAPP 2), ShowerPro (TAPP 1s) and PitcherPro.

Essential is tested to filter/remove over 70 common substances from tap water. The product is tested in accordance with NSF-42 and the lab results are available for download here.

EcoPro 5-stage filters filter/remove 100+ potential substances from tap water and reduces more than 30 others. The product is tested in accordance with NSF-42, NSF-53 and NSF-244.  This page provides a summary of what it filters and the reduction efficiency. The complete lab report is available for download at the end.

PitcherPro 3-stage filters remove 80+ potential substances from the tap water and reduces more than 30 others. The product is tested in accordance with NSF-42. Download PitcherPro Lab Results & Certifications – 22Nov2021

TAPP 1s is a 4-stage shower filter that removes 70+ contaminants from shower water including chlorine, limescale and heavy metals. The product is tested in accordance with NSF/ANSI 177. Download ShowerPro (TAPP 1s) Independent Lab Tests & Certifications 30Oct21

 

Substance Description of what is being filtered Reduction
Organoleptics parameters (taste, colour and odor) The unpleasant taste or smell of water is generally caused by Chlorine, its by-products and organic contaminants. 95% or more
Chlorine and Chloramine Chlorine is added to disinfect tap water from harmful viruses and bacteria. 95% or more
Chlorine by-products Over 100 by-products incl 32 known chlorine by-products (VOCs) such as THMs identified as potentially cancerous 95% or more
Microplastics Plastic pieces of a few micrometers length 95% or more
Heavy metals Occur naturally in trace amounts in water or caused by pipelines corrosion such as lead, zinc, manganese, copper, etc 90% or more
Pesticides 14 listed pesticides including Chlordane, Heptachlor, and Lindane 95% or more**
Herbicides 12 listed herbicides including 2,4-D and Atrazine 95% or more**
Nitrate & Nitrites Occur naturally in trace amounts or caused by contamination from fertilizers. 70% or more
Pharmaceuticals Pharmaceuticals in very small concentrations have been found in tap water. This includes e.g. Atenolol, Carbamazepina, Estrone, Meprobamat and Trimethoprim 95% or more**
PFAS This includes PFOA, PFOS and PFNA. Sometimes referred to as forever chemicals. 90% or more**
Pathogens Most “bad” bacteria including eColi as well as Microbial cyst including giardia and cryptosporidium 90% or more
Turbidity Turbidity is a measure of the degree to which the water loses its transparency due to the presence of suspended particulates. 90% or more
Limescale TAPP 2 prevents limescale from forming in the kettle, coffee machine, sink, water bottles, pitchers and anywhere else you use tap water thanks to our proprietary limescale inhibitor formula. 80% or more

* The percentages of efficiency of the filter as well as its lifetime will vary depending on the initial quality of your tap water. 

** Based on public research by NIH and other research institutions of activated carbon in block form as used in TAPP2. See what does activated carbon filters remove and reduce and complete list of what EcoPro 2 5-stage water filters remove including 100+ substances.

What EcoPro doesn’t filter

A common misconception is that a water filter should remove everything from tap water. Here’s a list of the substances and parameters that EcoPro does not remove/filter and why.

Substance(s) Description
TDS (Total Dissolved Solids) TDS is basically the charged minerals in your water such as inorganic salts and small amounts of organic matter that are dissolved in water. These are usually calcium, magnesium, sodium, potassium, carbonate, bicarbonate, chloride, sulphate and nitrates. Most lab reports use Electrical Conductivity instead of TDS. TDS does not in any case indicate if the water is drinkable or not.
Healthy minerals Minerals include calcium, potassium, magnesium, chloride, etc that humans need to survive. These essential minerals are insignificantly reduced by carbon blocks.
Hardness Hard water is water that has high concentration of Calcium and Magnesium. For drinking purposes, hard water is mostly an advantage. However, it causes limescale deposits that are often perceived as an issue.
pH pH is a measure of acidity or alkalinity of water. A pH value of 6.5-8.5 is considered normal and your body will adjust the pH to the body’s normal state (blood = pH 7.4) after drinking. There is no known health risk related to pH within the legal range.

Independent Lab Tests to confirm the filter works as stated

Every year we carry out lab tests with third party labs. Here’s an overview of one of these tests carried out by SimpleLab (US), AQA (Germany) and iTabe (Spain) three of the most renown labs in the world. The latest tests were carried out in Barcelona and Los Angeles December 2020*. The link below the table includes the full list of substances with external sources by the lab to verify the claims.

Parameter/Substance Before filtration After filtration Reduction
Total Chlorine (ppm) 0.8 <0.05 More than 95%
Chloramine (ppm) 0.8 <0.05 More than 95%
pH 7.8 7.9 Not applicable
Turbidty (NTU) 0.17 Not detected 100%
Microplastics (particles / L) 29 Not detected 100%
Nitrate & Nitrite (ppm) 0.22 Not detected 100%
Heavy Metals
(Average for Lead, Manganese, Zinc,
Barium) (ppm)
0.15 Not detected 100%
Chlorine disinfection bi-products
(THMs, VOCs, HAAs,..) (pbb)
6 Not detected 100%

*Note: The reason for picking Los Angeles, USA is that this was the worst tap water in terms of contaminants that we found during all the tests. Lab tests have also been carried out with water from Barcelona, Valencia, Mallorca, New York, Toronto, Milan, Malta, India, Bhutan, Venezuela, Indonesia and many other countries.
