About This WHOLE HOUSE WATER FILTRATION: Notice the difference immediately with our 3-stage water filtration process throughout your home. From every faucet enjoy crystal clear, drinkable, water and protect your health, pipes, and appliances. COMPREHENSIVE FILTRATION SYSTEM: The HEAVY METAL system was specifically designed to significantly reduce heavy metals using our premium KDF media in a process call redox, changing impurities into harmless byproducts. SOFTENER & APPLIANCE PROTECTION: Avoid costly repairs, ensure that pipes & appliances in your home are protected from dirt & silt build-up. It's recommended for those with Water Softener systems, install a filtration system at water inlet before Softener. FILTER SCHEDULE: Depending on whole home usage and inlet water quality, filters 1-3 should be replaced every 6-12 months, or 100K gallons of water filtration. Our 1" connection, and filters, allow for 0.25 gallons per second at 45-80 PSI. PLEASE NOTE: This 3-stage whole house water filtration system does NOT reduce TDS. If that is one of your desires, please consider one of our reverse osmosis systems - search "Express Water RO5DX" on Amazon.
