Frontier GRN Line protection is achieved using Electro-Positive Absorption Technology. 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 making Frontier Series II GRN-Line Filters the perfect choice for water bottle applications. Frontier GRN Line filters have been thoroughly tested by independent laboratories, and proven to consistently remove bacteria and protozoan cysts to ANSI/NSF Standard 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.
