Filox R is a filter media that consists of 75 – 85% manganese dioxide. As the level of MnO2 is very high (Birm contains 1% MgO2, Greensand contains 3% MgO2), it is an excellent media to remove iron, manganese and hydrogen sulfide.
In many cases it can be used without additional oxidation, depending on the presence of dissolved oxygen. Thanks to the excellent catalytic properties service flow rates are very high compared to many other media.
Again compared to other media Filox R is very heavy and demands frequent backwashing.
