Enjoy clean, clear & iron-free water at every faucet this 3-stage 20 inch bb whole house water purification system can effectively remove sediment, synthetics and iron to deliver cleaner more manageable water to every faucet for all your water needs. Ideal for whole house filtration, light commercial use or industrial applications with a fast flow rate. The 1st stage sediment filter captures and traps dirt, sand, silt, scale and rust particles down to 30 microns. This durable, polyester filter has a pleated design to maximize dirt-holding capacity and is washable and reusable. The 2nd stage iron filter utilizes high purity manganese dioxide to effectively reduce iron, iron staining and the metallic taste in your water by converting soluble ferrous iron into insoluble ferric iron. The 3rd stage carbon filter is a radial flow granular activated carbon (GAC) cartridge that adsorbs the insoluble ferric iron to effectively treat iron. Lastly, chlorine, odors, taste and organic compounds are removed by the carbon filter to provide synthetics-free water to every faucet and water outlet. High quality housing sets consist of three (3) 20"x4. 5" industry standard bb housings. The polypropylene (HFPP) cap has 1 inch fnpt inlet and outlet ports for fast-flow rates and are pre-attached to a mounting bracket for easy setup and installation.

Reduces fine particles, rust, and sediment for cleaner and clearer water. Chlorine free water for softer skin and smoother hair after every shower. Protects against harmful impurities and organic compounds (VOCs) in tap water. Reduces formation of iron and mineral deposits and potential for clogs.
