The Aquios™ AQFS220 salt free water softener and filter system utilizes a natural, commercial strength technology and performance in a sleek, compact design. This system will ensure that sediment, chlorine and other undesirable materials are removed from your water, and that calcium, magnesium and other minerals found in hard water do not build up and create scale on your fixtures and pipes, and provide clean, pure and healthy water to you and your family.

Unlike salt-based systems, the minerals that make water “hard” are not removed. Instead, Aquios™ utilizes a commercial, natural technology that ensures that these minerals do not accumulate or build up on faucets, water heaters, shower heads, internal pipes or any other device that utilizes your existing water source. This natural technology is a polyphosphate additive known as Siliphos® which inhibits scale deposits and, over time will slowly reduce scale buildup on your pipes and appliances. The result...most scale-causing minerals pass through the systems instead of forming deposits on pipes, appliances and water heater.

You will notice a difference in “water feel”, but not one that is “slippery” as is commonly found with salt water softeners. The Aquios™ salt free water softener & filter system is a revolutionary approach to water treatment and conditioning. It combines carbon block filtration (rated at 5 microns) with commercial grade water conditioning to deliver a full house, all in one solution. Our unique design ensures virtually no pressure loss or reduction in water flow rate and requires absolutely no programming, electricity or maintenance. It also comes with a 20 year warranty on the housing and valve.  Now that's simple.....

The Aquios™ Water Treatment System includes your first cartridge and should last an average family between four (4) to six (6) months before it requires replacement.*
