How it works

3 stage system

Chlorine Taste & Odor Reduction

Tap water passes through Pentair’s patented Diamond Flow technology – a combination of two technologies in one: a carbon block designed to reduce taste and odors, and a poly spun shell wrapped around the carbon block to reduce sediment and help protect the life of the carbon block.

Contaminant and Impurities Reduction

Water then moves through the reverse osmosis membrane which reduces a broader range of contaminants and impurities found in your home water. The membrane separates the water containing contaminants and sends it down the drain while pushing the more pure water in to the next stage. Pentair’s patented Green RO (GRO) membrane reduces the amount of water waste compared to standard members in the market.

Better Tasting Water

Water then passes through the final stage, a granular activated carbon (GAC) filter, which reduces any remaining contaminants while “polishing” the water to give you better tasting water. This water is then stored in a 3.2 gallon storage tank that hold the water until you are ready for clearer, better tasting water.

Lead is harmful even in small doses, as the EPA attests. The EPA has set the maximum contaminant level goal for lead in drinking water at zero. Learn about how lead gets into your water and which products are recommended to reduce its effects.

Learn About Lead

Chloramine is a disinfectant that consists of five parts chlorine and one part ammonia. So, in a sense, it’s kind of “chlorine plus.” Find out how it gets into your water and how you can treat it.
