Frontier Series II RED Line Replacement Filters with Mixed Media Filtration Technology take advantage of a unique The Frontier Series II RED Line filter incorporates our patent pending Mixed Media Filtration Technology, a unique combination of the most advanced filtration materials and media science available today. Using a proprietary filter design and manufacturing method, Aquamira engineers have created a multi-stage filtration system that incorporates the power of electro-positive 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 is proven effective by independent laboratories to consistently remove protozoan cysts, bacteria, and virus to ANSI/NSF – 53 and US EPA standards without the need for cumbersome “back-flushing” requirements or disinfecting chemicals such as chlorine, bromine, or iodine. The patent pending carbon sleeve design increases the absorptive capability required to remove harmful chemicals, bad tastes and odors to ANSI/NSF – 42 requirements, and has been tested and proven effective in reducing Cyanotoxins such as Microcystin and other biotoxins. Frontier Series II RED Line filters assure maximum protection in high risk applications, while providing high flows and long service life.

Frontier Series II capsule was developed by our engineers to provide the easy and secure connections with minimum fuss and fittings. Frontier Series II filters connect easily to any Frontier water bottle cap with a simple “push and twist.” They also connect directly to 1/4″ tubing for “in-line” gravity flow and hydration applications.
