About This

• COMPATIBLE REPLACEMENT MODELS – This 20 micron 10 x 4.5 sediment water filter 2-pack is a replacement for Pentair S1-BB, American Plumber W20CLHD, 155405-43, 155405-51, PC20-BB-S and fits most standard 10 inch x 4.5 inch whole house filter housings.
• 20 MICRON SURFACE SEDIMENT FILTRATION – Designed to capture coarse sediment such as sand, dirt, silt, and rust flakes commonly found in municipal water supplies, helping protect plumbing lines and household fixtures from visible particulate buildup.
• RESIN IMPREGNATED PLEATED CELLULOSE MEDIA – Surface filtration design traps particles on expanded pleated media while resin impregnation enhances structural durability, supporting consistent flow in moderate sediment conditions.
• WHOLE HOUSE ENTRY-POINT PROTECTION – Commonly installed at the main water line in basements, garages, or utility rooms to reduce sediment before water reaches faucets, appliances, and downstream filtration components.
• SERVICE LIFE VARIES BY WATER CONDITIONS – Replacement frequency depends on sediment levels and water quality; because 20 micron surface-filtration media captures larger particles, monitoring flow or pressure changes helps determine when cartridge replacement is needed to maintain consistent system performance.
