Designed specifically for well water contamination to protect from bacteria, viruses and other contaminants commonly found in private well water, this system features the added starlight UV filtration and simply soft salt-free water softener. Get healthy, clean, great-tasting water from every tap in your home by removing up to 97% of the chlorine in regular tap water and reducing harmful water contaminants such as pesticides, herbicides, rust, silt, sediment, water soluble metals and industrial solvents for 5 years or 500,000 gallons with the premium rhino whole house filter. Includes Aquasana's Salt-Free Water Conditioner which is designed to hook up seamlessly with your whole house water filter system. SCM salt-free technology will naturally and safely reduce scale buildup on internal pipes and plumbing without the use of harsh salt or chemicals. Unlike salt based softeners, Aquasana's Salt-Free Water Conditioner will not demineralize your water, harm your pipes with harsh salt, or put excessive amounts of sodium waste into our communal water supply. Pex tubing is not included. Contaminant reduction testing and resulting values are based on Rated Flow Rates indicated above. Values will vary based on faster or slower flow rates.
