PiMag Waterfall Product Test

There is an increase in publications that suggest our water supply is contaminated with various metals, pesticides, herbicides, insecticides and fungicides. Nikken have completed this PiMag ® Waterfall Product test that shows reductions in a large number of these contaminants when using this filtration system.

PiMag Waterfall Product test

The process conducted in our laboratory is to deliberately contaminate the tap water with a high level of each contaminant and to then take a reading for each one after filtration.

Water in Your Area

Please note that the substances removed or reduced by this device are not necessarily in your water. Because Nikken has no information on water quality in your area, this is something we recommend you find out from your water supplier.


  • Chlorine 90% 90%
PiMag Waterfall Filter showed a 90% reduction in chlorine compared with UK tap water.


The metals below are regularly tested for by water companies and filtered through their systems to make sure that they do not exceed the regulation PCV (Prescribed Concentration or Value). The PiMag Waterfall Filter showed the following reductions versus UK tap water:
  • Mercury 96% 96%
  • Aluminium 95% 95%
  • Chromium 90% 90%
  • Cadmium 87% 87%
  • Lead 91% 91%
  • Copper 87% 87%
  • Iron 73% 73%
  • Arsenic 68% 68%
  • Nickel 83% 83%


Nikken has tested 91 various contaminants and the consolidated results are shown here. These percentages indicate the maximum level of reduction for each category:
  • Organochlorine (insecticides) – 24 Substances Tested 99% 99%
  • Organophosorus (pesticides) – 13 Substances Tested 97% 97%
  • Urons – 13 Substances Tested 90% 90%
  • Triazines (herbicides) – 7 Substances Tested 76% 76%
  • Acidics – 18 Substances Tested 94% 94%
  • Metaldehyde (pesticide) 84% 84%
  • Trihalomethanes (THM’s) / Solvents – 4 Substances Tested 95% 95%
  • Polycyclic Aromatic Hydrocarbon (PAH) – 8 Substances Tested 86% 86%
  • Chlormequat (plant growth regulator) 72% 72%
  • Glyphosate (herbicide) 80% 80%
  • Phosphorus 91% 91%


These contaminants are not necessarily in your tap water, but where any contaminant residual is present in a treated water supply, the PiMag ® Waterfall product test shows that it is effective in significantly reducing the level of contamination.
