Enhance your home water with confident, whole-house iron reduction

Iron in water can subtly affect taste and leave stubborn rust traces on fixtures. The Pentair Pentek RFFE20-BB Big Blue 20-Inch Iron Reduction Filter is designed to address these realities at the point where water enters your home. By protecting the main line, this replacement cartridge aims to deliver clearer water and cleaner surfaces across every tap, shower, and appliance.

Key benefits at a glance

  • Reduces up to 3 PPM of dissolved iron, helping minimize metallic taste in drinking water.
  • Prevents rust stains on sinks, toilets, and plumbing fixtures, contributing to a brighter bathroom and kitchen.
  • Provides whole-house filtration on the main water line, a practical fit for well water homes.
  • Fits all 20" Big Blue housings and can replace any 4.5" x 20" iron-reducing filter for flexible setup.
  • Desig ned for regular replacement—about every 3 months for a family of four, aligning with iron exposure levels.

Real-life use and practical scenarios

Imagine drinking water with a milder taste and fewer metallic notes, while faucets and fixtures stay looking cleaner. This cartridge is intended to work across the whole home, so you may notice a cohesive quality in water used for cooking, cleaning, and laundry—especially in homes with well water.
