Watts LOCKSMITH™ FLLAIO-125 Series Filox® whole house iron filter systems provide a chemical‑free solution for removing red staining iron, rotten egg–smelling hydrogen sulfide, and black staining manganese from residential water supplies. These systems use a process called AIO (Air Injection Oxidization), which allows the natural air we breathe to charge the water with oxygen. Together the oxygen and contaminants are introduced onto the surface of our catalytic filtration media. The oxygen oxidizes the contaminants, allowing the media to effectively remove them from the water. The Filox media uses the injected oxygen to oxidize the contaminants and then traps the impurities.
Each system features the Watts LOCKSMITH™ control valve with advanced programmable features to support reliable, efficient operation. The FLLAIO‑125 Series is available in multiple media capacities to meet a range of whole‑house filtration needs.
