About This

  • COMPATIBLE REPLACEMENT MODELS – Designed to fit standard 20 x 4.5 whole house filter housings and a replacement for Pentair polypropylene filter cartridge Pentair DGD-2501-20, 155360-43, P1-20BB, SDC-45-2001, FPMB-BB1-20, and SDF-45-2001; suitable for most 4.5” x 20” water filter housings
  • 1 MICRON DEPTH SEDIMENT FILTRATION – Spun wound polypropylene construction captures fine particles throughout the cartridge depth, helping reduce rust, sand, silt, dirt, and scale commonly present in well water and municipal water systems.
  • FINE SEDIMENT POLISHING DESIGN – The graded density depth structure traps larger debris on the outer layers while finer particles are captured deeper inside, making 1 micron filtration ideal for applications needing finer sediment control ahead of downstream filtration.
  • 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 installed as a secondary or polishing-stage sediment filter to help protect plumbing, appliances, water softeners, and carbon filters from fine particulate buildup.
