⭐ Key Features

•COMPATIBLE REPLACEMENT MODELS – Designed to fit standard 20 x 2.5 whole house filter cartridges and a replacement for Pentair P1-20, SP-P1-20, PX01-20, PS1-20C, 155755-43, 255691-43, SDC-25-2001, 93125, and 155304-43, along with many equivalent 2.5” x 20” water filter housings.

•1 MICRON DEPTH SEDIMENT FILTRATION – Spun wound polypropylene depth media captures fine sediment throughout the cartridge, helping reduce rust, sand, silt, dirt, and scale commonly present in well water and municipal water systems.

•FINE SEDIMENT POLISHING DESIGN – The graded density structure traps larger particles on the outer layers while finer particles are captured deeper inside, making 1 micron filtration ideal for sediment polishing ahead of downstream filters.

•SERVICE LIFE VARIES BY WATER CONDITIONS – Replacement frequency depends on sediment levels, water quality, and micron rating; finer filters capture smaller particles more quickly, so monitoring flow or pressure changes helps determine when cartridge replacement is needed.

•FINE SEDIMENT PROTECTION FOR WHOLE HOUSE SYSTEMS – Commonly used as a polishing-stage or secondary sediment filter, or as a first-stage filter only in low-sediment water conditions, to help protect plumbing, appliances, water softeners, and carbon filters from fine particulate buildup.
