Tested to only the highest standards
Firewall technology has been rigorously tested by a team of microbiologists from University of Arizona, and test results have demonstrated that Firewall is effective in inactivating the human form of the COVID-19 strain, with a colony reduction of over 99.999%.
Firewall is also the only purification system certified by IAPMO R&T to NSF/ANSI 55 Class A, NSF P231 Protocol for Microbiological Water Purifiers, US EPA Guide Standard, NSF/ANSI 372 for lead free compliance and CSA B483.1. No other water dispenser features this standard of certification.
