Frontier RED LINE Filters with Mixed Media Filtration Technology take advantage of a unique combination of the most advanced filtration materials and media science available today. Using a patent pending filter design and manufacturing method, Aquamira engineers have created a multi-stage filtration system that incorporates the power of electropositive charge differential to “pull” particles as small as viruses out of the water stream while still maintaining high flow. This technology has been thoroughly tested and proven effective by independent laboratories to consistently remove protozoan cysts, bacteria, and virus to ANSI/NSF Standard 53 and US EPA standards without the need for cumbersome “back-flushing” requirements or disinfecting chemicals such as chlorine, bromine, or iodine. Frontier RED LINE patent pending carbon block sleeve design increases the absorptive capability required to reduce harmful chemicals, bad tastes and odors, to ANSI/NSF Standard 42 requirements, and have been tested and proven effective in reducing Cyanotoxins such as Microcystin and other biotoxins. Frontier RED LINE filters assure maximum protection in high risk applications, while providing high flows and long service life in the most compact, lightweight solution available today.
