Pentek R50-Bb Big Blue Pleated Polyester Sediment Filter Cartridge, 50 Micron (item #155053-43)

The Pentek R50-BB (Item #155053-43) is a 10" Big Blue pleated polyester sediment cartridge with a 50-micron nominal rating, ideal for capturing coarse sediment like sand, silt, rust flakes, and scale across an entire home's water supply. With over 16 square feet of pleated polyester media and a molded polypropylene endcap for a secure fit in standard Big Blue housings, the R50-BB delivers strong dirt-holding capacity while keeping pressure drop low. It's fully reusable and resistant to bacteria and chemical attack, and works well as a pre-filter ahead of carbon block or RO systems to protect them from larger particulate.
