RapidPure Intrepid 1.9L Water Bottle Filter is 4.5in and comes with the Nano Filtration Technology designed for drinking water purification systems. Each filter comes with two (2) straw connectors which allow a single RapidPure assembly to fit three different straw diameters without reducing ID of straw. The pre-filter wrap is washable to remove large sediment build-up and extend sub-micron filter life.
