Independent laboratory tests

The filtration systems Weeplow Gravity Water Systems have been tested under real conditions by several independent laboratories around the world.
Analyses conducted by laboratories in the United States and in Europe have demonstrated that the O’Pure 2 filters used in our systems have a reduction capacity of nearly 99.99% of bacteria, including E. Coli.
Additional tests have also confirmed a reduction greater than 99.9% of forever chemicals (PFAS).

The laboratory SGS, present in over 140 countries and internationally recognized for its expertise in the field of water, has conducted several series of analyses on our O’Pure 2 filters.
These tests specifically focused on the MS2 virus, with a measured reduction of 99.9999%, as well as on various pesticides and heavy metals, according to the NSF/ANSI 42 and 53 standards.

Unlike other brands, Weeplow has made the deliberate choice to conduct analyses in several independent laboratories in order to provide a maximum of transparency to its customers.
