We believe that responsible manufacturing includes creating and maintaining a strong evidence base for our product claims and their intended impacts. All products undergo rigorous independent testing to meet or exceed protocols established by the US Environmental Protection Agency (EPA) and National Sanitation Foundation (NSF) We also built and run an ISO accredited water laboratory based in Vietnam that does quality validation and testing of all of our new and existing products.
