Air injection system combined with catalytic carbon offers a wide range of water treatment in a single system. In addition to great iron and hydrogen sulfide removal, the carbon based media will reduce a wide range of tastes, odors, and chemicals in the water, providing higher quality water than typical iron filters. Advanced single tank pump-free design lowers cost, reduces maintenance, and provides a smaller footprint than standard systems that use air pumps or separate tanks.
