About Us

AFI USA Group was founded in 1982 by an engineer who worked in the water purification industry for over 30 years and has invented over 15 different pressure-canister water filters. Our staff has an additional 30 years of combined experience working with water filtration and plastics of all types. Although we initially started our business by selling filtration systems for large aquariums, we eventually moved towards water filtration products for people.

By putting all of our experience and knowledge together, we've been able to create amazing products like the Patriot Filter and the Clear Water Mountain Straw. All of our water filtration systems comply with National Sanitation Foundation and American National Standards Institute (NSF/ANSI) standards 42 and 53 for the reduction of specific contaminants found in drinking water that are particularly hazardous to your health. We have customers located across the United States, and we're currently exploring the international market due to the high demand for clean water around the globe.

Our Products Protect You Against Contaminants Such As Pathogenic Parasitic Organisms, Lead, E. Coli, and Mercury
