The AIO Chemical Free Iron filter is intended to be an effective and
economical way to remove iron from water without the use of messy and
dangerous chemicals or expensive pumps or an external venturi. The AIO
valve uses a unique process to create an air bubble at the upper portion of
the tank to oxidize any ferrous iron prior to being filtered by the media. It can
also be used to remove low concentrations of dissolved hydrogen sulfide
and manganese from water.

Activated carbon filters use adsorption to treat residential water. These filters protect the home by removing or significantly reducing chlorine, chloramines, volatile organic compounds (VOCs), H2S, as well as many other dangerous contaminants.

Incoming raw water passes through a compressed pocket of air contained in the first tank. The air precipitates the iron into solid form and is removed when it passes through the filters media bed contained in the second tank. The media acts as a catalyst in the reaction between iron and oxygen that also causes the iron to precipitate into a solid.
