Technical Information

With the introduction of the patented Series IV RED Line filter design and manufacturing method, Aquamira engineers created a multi-stage filtration system that incorporates the power of electro-positive charge differential to "pull" particles as small as viruses out of water while still maintaining high flow. All Aquamira Series IV filters are designed to be interchangeable in a variety of Aquamira products so that you can choose the best filter for your unique situation. The RED Line filter is the only filter made in the USA and certified to remove protozoan cysts, bacteria, and viruses to US EPA standards when properly installed in a Series IV filtration system. It does all this without the need for cumbersome "back-flushing" or disinfecting chemicals such as chlorine, bromine, or iodine. The patented design also reduces harmful chemicals, bad tastes, and odors to ANSI/NSF - 42 requirements and has been tested and proven effective in reducing Cyanotoxins such as Microcystin produced by algae blooms in the Great Lakes, something no hollow fiber filter can do. Frontier RED Line filters assure maximum protection in high risk applications while providing high flows and long service life in the most compact, lightweight, interchangeable and replaceable cartridge available today.
