Radial-flow cartridges designed to **reduce up to 3 ppm of dissolved iron** in well and borewell water. Installed in 10" and 20" Big Blue housings, they help eliminate metallic taste and orange/brown staining without adding chemicals—making them safe for drinking-water applications.
Rust stains, metallic taste and frequent heater failures frustrate homeowners. RFFE cartridges target dissolved iron at the entry point so fixtures stay cleaner and plumbing is better protected.
Reduces dissolved iron that causes metallic taste and orange/brown staining in sinks, toilets, tubs and fixtures.
Helps reduce the possibility of damage to pipes and water heaters by keeping iron deposits under control.
Adds no chemicals to the water, making it suitable for drinking-water applications when used on microbiologically safe supplies.
