Replacement Filter (GRN-II-80)


The WaterBascs GRN Line Replacement Filter provides the perfect solution for drinking water safety, by incorporating GRN Line Protection with the with the convenience of WaterBasics Series II connectivity to easily connect to WaterBasics Water Bottles, Gravity Flow Filtration Kits, Bag to Bag Filtration Kits, WaterBasics Pumps and Hydration Bladders. The GRN Line Replacement Filter even comes complete with a mouthpiece and straw so you can drink directly from any natural water source if the circumstance requires. No other replacement Filter is usable straight out of the box. You can depend on WaterBasics.


WaterBasics 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 WaterBasics GRN-Line filters the perfect choice for water bottle, pump and gravity flow applications. GRN Line filters have been thoroughly tested by independent laboratories, and proven to consistently remove protozoan cysts, and bacteria to ANSI/NSF Standard 52, 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. WaterBasics GRN Line filters provide superior biological protection, high flows and long service life in a compact, lightweight, and easy to use cartridge.

We understand connectivity.  WaterBasics Series II Connectivity was developed by our engineers to provide the maximum potential for connections with a minimum of fuss and fittings. Series II filters connect easily to tubing for gravity flow and hydration applications, to any Aquamira water bottle cap, to standard water storage containers, to our unique WaterBasics pump, and can even be quickly converted to an emergency straw configuration straight out of the package. Fewer fittings means one filter is all you need to provide the needed protection for you and your family without worrying about “will it fit?
