Expert Endorsements

Firewall’s astounding performance has been proven by some of the world’s top independent laboratories and most demanding institutions. First, excellent results were obtained by leading labs Sino Analytica and the Dr Lörcher Institute, testing under extreme conditions.

Then came the testing and certification to NSF 55a and P231 by the WQA (Water Quality Association).

Exceptional results

Even more tests led to a public endorsement from experts at the City of Paris Water Authority, the people responsible for the health and safety of millions of people.

University Hospital Zurich in Switzerland was so impressed it has commissioned its own testing, and validated the excellent purification performance.

Don’t take our word for it. All these reports are available on request, and we continue to update our files as more glowing endorsements from rigorous studies come in.
