Hydrox removes iron, hydrogen sulfide, and manganese. It continues to perform even when other iron-reduction media fail, thanks to its resistance to O₂, Cl₂, and ozone. Because Hydrox requires a smaller quantity to achieve the same flow rates as other media types, media costs are reduced. It also offers the highest flow rate among standard iron-removal media and needs no chemicals for regeneration.

Since less Hydrox is typically needed, smaller tanks can be used to achieve the same flow capacity, further lowering system costs. In addition, using air filter tanks increases backwash efficiency by providing greater lift, conserving water, and improving the removal of particles such as iron or sulfur that have been captured by the filter.
