How it Works

Ultimate PFAS Filter System With UV

First Stage: Water enters our 5-micron sediment filter with scale inhibitor to remove dirt, sand, silt, and other particulates while conditioning hard water to prevent limescale buildup. This protects and maximizes the efficiency of all subsequent stages.

Second Stage: Our 1-micron PFAS filter is designed to reduce PFOS/PFOA (forever chemicals), cysts (Giardia and Cryptosporidium), chlorine, VOCs, THMs, and other chemicals while improving taste, odor, and water clarity.

Third Stage: Our 1-micron PFAS filter is designed to reduce PFOS/PFOA (forever chemicals), cysts (Giardia and Cryptosporidium), chlorine, VOCs, THMs, and other chemicals while improving taste, odor, and water clarity.

Fourth Stage: Our UV Home Purification system features a sleek 316L stainless steel chamber housing a UV lamp with continuous sensor monitoring. Diagnostics and essential system information are clearly displayed on the intuitive controller screen.

Ultimate PFAS Filtration

What is PFAS? (The Hidden 'Forever Chemicals' in Your Water).

PFAS (per- and polyfluoroalkyl substances) are persistent synthetic chemicals found in many products. They contaminate water sources across the USA, with the EPA estimating that 60% of the population may face PFAS in tap water, exposing around 70 million people to these "forever chemicals." Our Ultimate Whole House PFAS Filtration system, with dual 1-micron filters, protects your entire home from these toxic substances.
