Pro-OX Heavy-Duty Iron Filters

Pro-OX is a solid manganese dioxide ore, heavier than our Pro-OX Lite media. Choose it if you prefer a dense, long-lasting bed and your well pump can supply the stronger backwash flow it needs. Customers report many years of service.

Choose the valve: 5900-BT (American-made, Bluetooth app, AIR upgrade on 1.0 CF and up; not on 13x30 short tanks) or 7500-M (simple timer valve).
