Iron Reduction
Pentek RFFE10-BB & RFFE20-BB Radial Flow Iron Reduction Cartridges
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.
Why It Matters
Key Benefits
Improves Taste & Appearance
Reduces dissolved iron that causes metallic taste and orange/brown staining in sinks, toilets, tubs and fixtures.
Protects Plumbing & Heaters
Helps reduce the possibility of damage to pipes and water heaters by keeping iron deposits under control.
Chemical-Free Solution
Adds no chemicals to the water, making it suitable for drinking-water applications when used on microbiologically safe supplies.
For use in Pentek 10" and 20" Big Blue housings installed on the main cold-water line—ideal for residential whole-house and light-commercial installations with dissolved iron up to 3 ppm.

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.

| Micron Rating | Not rated (NR) – specialty iron-reduction media, not specified as a particulate micron filter. |
| Flow Rate | Not specified; select housing and plumbing to meet whole-house flow requirements while respecting pressure-drop limits. |
| Dimensions (L × W × D) | RFFE10-BB: approx. 4.5" × 10" (10" Big Blue). RFFE20-BB: approx. 4.5" × 20" (20" Big Blue) – for use in Pentek Big Blue housings. |
| Operating Pressure | Not specified; operate within the pressure rating of the installed Big Blue housing and system design. |
| Operating Temperature | Not specified; typical use within standard cold-water housing limits (consult housing datasheet). |
| Connections | Drop-in radial-flow cartridges for Pentek 10" and 20" Big Blue (4.5" diameter) filter housings. No direct threaded connection. |
| Certifications | Not specified on RFFE series datasheet; use in systems that meet local plumbing and drinking-water regulations. |
| Application | Reduction of dissolved iron (up to 3 ppm) in residential and light-commercial cold-water systems using Pentek Big Blue housings. |
