- COMPATIBLE REPLACEMENT MODELS – This 20 micron 20 x 4.5 pleated cellulose sediment water filter is a replacement for Pentair S1-20BB, 155305-43, W20CLHD20, 155305, FF20BBPS-20, ECP1-20BB, 255493-43, and 4PAY4, and fits most standard 20 inch x 4.5 inch whole house filter housings.
- 20 MICRON SURFACE SEDIMENT FILTRATION – Pleated cellulose media captures larger sediment such as sand, rust flakes, dirt, and visible particulate matter on the surface of the cartridge, helping maintain strong household water flow in moderate sediment conditions.
- PLEATED CELLULOSE MEDIA DESIGN – Surface filtration with increased pleated area distributes sediment evenly across the cartridge face, supporting steady flow performance in municipal and treated water systems with visible sediment.
- 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.
- COARSE SEDIMENT PROTECTION FOR WHOLE HOUSE SYSTEMS – Commonly used as a first-stage or entry-point sediment filter to help reduce larger particulate matter and protect plumbing fixtures, appliances, and downstream filtration components from sediment buildup.
