The Hydro Life Inline Hose Water Filter is ideal for trailers, RVs and boats with an exterior water hook up. It installs quickly and easily without tools and filters all the water coming into your RV or boat. The filter is small and compact and can be used in conjunction with the Hydro Life under counter filter kit for even greater performance and extended life. The Hydro Life filter utilizes the patented KDF media in conjunction with granular activated carbon (GAC) to provide superior filtering and protection from many contaminants. Fine mesh activated carbon provides safer, cleaner, better tasting water by filtering our contaminants including those that cause bad odor and taste. The EPA approved filter media, KDF, controls bacteria growth that may occur in standard carbon filters. Working pressure range: 20-100 PSI. Maximum flow rate: 2 GPM.
