Birm Media – 1 Cubic Foot

Iron & Manganese Reducing Filter Media for AIO Systems

Birm® Media (1 cu. ft.) is a highly efficient and economical solution for removing dissolved iron and manganese from well water. Acting as a permanent, insoluble catalyst, Birm® enhances the natural oxidation process between dissolved oxygen and iron compounds, producing ferric hydroxide that can be easily filtered out.

Unlike other media, Birm® does not require chemicals or regeneration—only periodic backwashing is needed. With long material life, wide temperature tolerance, and extremely high removal efficiency, Birm® remains one of the most reliable and cost-effective media for whole house and commercial systems.
