3-Cartridge Filtration: Use our three-cartridge (5-micron PP cotton, 5-micron CTO, and 0.2-micron filter) RV water filtration system to remove impurities from tap water effectively. It traps sand, rust, sediment, adsorbs chlorine, chloramine, iron, manganese, lead, undesirable colors, and odors, while blocking microplastics and reducing the load of microbial contaminants. Provides safer and purer water for you Extended Lifespan: The RV filter system uses a 2.5 x 10 in filter cartridge, with a filtration flow rate of 2.9 GPM, capable of filtering 7,500 gallons of water without clogging. Ensures the cartridge maintains purification accuracy without overloading. To replace the cartridge, use the included wrenches to remove the filter housing Leak-Proof: The sturdy carbon steel bracket protects the freeze-resistant, impact-resistant PP housing
