The Series IV GRN Line filter is designed to be easy-to-use, lightweight, compact and reliable. Frontier GRN Line filtration is achieved using Electro-Positive Absorption Technology. The charged micro-glass fibers "pull" organisms as small as bacteria out of the water stream while still maintaining high flow rates and low pressure drops. GRN Line filters have been thoroughly tested by independent laboratories and are proven to consistently remove protozoan bacteria and protozoan cysts to ANSI/NSF - 53 and US EPA standards without the use of disinfecting chemicals such as chlorine, bromine or iodine. The addition of sub-micron carbon particles into the filter media increases the absorptive capability required to reduce chlorine and harmful chemicals, bad tastes, and odors to ANSI/NSF - 42 standards. Frontier GRN Line filters provide superior biological protection, high flows and long service life in a compact, lightweight and easy-to-use cartridge. The Frontier Max Series IV GRN Line filter is packaged in a lightweight, no-waste cardboard storage tube that protects your spare filter from the bumps and drops associated with outdoor gear making it safe to store even in the bottom of your pack. The tube is sealed with a protective label that indicates if the filter has been opened to assure quality and indicate use.
