Features:
- EXTENDED FILTER LIFE WITH PLEATED DESIGN - Resin-impregnated cellulose media is pleated around a polypropylene core, maximizing dirt-holding capacity for longer service between replacements
- 20 MICRON SEDIMENT FILTRATION - Captures dirt, sand, silt, rust, and sediment particles down to 20 microns to help protect plumbing fixtures, appliances, and downstream filters
- FOR CHLORINATED WATER SUPPLIES ONLY - Cellulose filter media requires chlorinated municipal water; not suitable for well water or non-chlorinated sources where bacteria may compromise the media
- FITS STANDARD BIG BLUE HOUSINGS - Drop-in cartridge measuring 4.50" x 9.75" fits all Pentair Pentek Big Blue 10" x 4.5" housings and BBFS systems; polypropylene endcaps include gaskets
- MAINTAINS STRONG WATER FLOW - Low 1.2 psi pressure drop at 10 gpm ensures minimal impact on household water pressure; operates in water temperatures from 40 to 145 degrees F
Details: The Pentair Pentek S1-BB is a whole-house sediment filter cartridge engineered for reliable 20 micron particle reduction in chlorinated municipal water systems. Its pleated, resin-impregnated cellulose media delivers significantly more filtration surface area than standard non-pleated cartridges, allowing the S1-BB to hold more dirt and last longer between changeouts while maintaining low pressure drop across the filter. Built with a polypropylene core for structural strength and polypropylene endcaps with integrated gaskets, the S1-BB provides a secure, leak-free fit in all standard Big Blue 10" x 4.5" housings and BBFS filtration systems. The sonically welded overlap seam prevents media bypass, ensuring consistent filtration performance throughout the life of the cartridge. Important: This cellulose media cartridge is designed exclusively for use with chlorinated water supplies. For non-chlorinated or untreated water sources such as private wells, use a polyester-based filter cartridge instead. Operating temperature range is 40 to 145 degrees F.
