If you ever shed a tear when it came time to replace your Frontier Pro because the filter was exhausted, now you can change out filters as needed and carry spares at under an ounce each. The new replaceable GRN Line filter removes everything the old Frontier Pro filter removed plus bacteria with less weight.
Frontier GRN Line filtration is achieved using our unique 2 stage Electro-Positive Absorption Technology. The replacable pre-filter disk removes larger particles, then the final 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 cysts, and bacteria 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 patented design of the Frontier Pro filter system includes the unique Cap Strap™ cap system to retain the cap and protect the patented Bite Me™ valve from contamination along with providing a sure grip on the filter that fits comfortably in your hand. The filter casings are constructed of high impact FDA-grade ABS plastic to assure long life even in harsh environments. The UQC universal connectivity system allows connection to standard qwick connect fittings, the draw tube provided with the system, any ¼” ID tubing such as hydration drink tubes, and 28mm threaded bottles such as Platypus® and other light weight flexible bottles. You will be amazed that a filter this small can do so much.
