The Pentek R30-20BB (Item #155430-43) is the largest cartridge in the R Series lineup — a 20" Big Blue pleated polyester filter rated at 30 microns nominal, built for high-flow whole house sediment reduction (up to 20 GPM). Its extended pleated polyester media, wrapped around a polypropylene core with a molded Big Blue endcap, provides maximum dirt-holding capacity for larger households or commercial applications with higher water demand. Reusable and resistant to bacteria and chemical attack, the R30-20BB is well-suited as a robust sediment pre-filter ahead of downstream carbon, softening, or RO equipment.
