Product Description
Pentair Pentek RFFE20-BB Big Blue Water Filter, 20-Inch, Whole House Radial Flow Iron Reduction Replacement Cartridge, 20" x 4.5", White
- IMPROVES WATER TASTE - Reduces up to 3 ppm of dissolved iron to cut the metallic taste it causes, for cleaner, better-tasting water from well or municipal supplies throughout your home.
- HELPS REDUCE RUST STAINING - Helps clear the orange and brown staining that iron leaves on sinks, toilets, tubs and fixtures, and lowers the chance of iron damage to pipes and water heaters.
- RADIAL FLOW IRON REDUCTION - Designed for the 20-inch Big Blue housing and installed on the main cold-water line after the pressure tank or meter. For best results, pair with a sediment pre-filter and a carbon post-filter.
- FITS ALL 20-INCH BIG BLUE HOUSINGS - Measures 20" x 4.5" and drops into any 20" Big Blue or other heavy-duty housing, replacing any 20" x 4.5" iron reduction cartridge. Adds no harmful chemicals and is safe for drinking water.
- LONG SERVICE LIFE - Handles roughly 26,000 gallons at 3 ppm iron, about 3 to 4 months for a household of four, and lasts longer at lower iron levels. Replace when metallic taste or staining returns.
This Pentek 155263 RFFE20-BB radial flow iron reduction cartridge is suitable for reducing the presence of dissolved iron in water supplies with concentrations up to 3 parts per million (ppm) for improved taste, less staining, and reduced chance of pipe and water heater damage.

They are made of densely packed synthetic or natural fibers that trap suspended particles, materials that block microbes or adsorb unwanted chemicals, or substances that cause a chemical change, such as acid neutralization. For most residential, commercial, and industrial applications, water filters are manufactured in the form of replaceable cartridges that fit inside permanent housings. Filtration systems typically consist of a series of two or more types of filters, each designed to remove different contaminants. The performance of filters is measured by the minimum particle size that is blocked, the percentage of particles or microorganisms that are removed, the downstream concentration of unwanted chemicals, the maximum flow rate, and the amount of water that can be filtered before the filter must be replaced. Water filters are used in a wide range of applications, including drinking water purification, swimming pools, industrial processes, and irrigation, among others.
