Tier1 20 Micron 10 x 4.5 Water Filter | Spun Wound Polypropylene Whole House Sediment Water Filter Cartridge | Replacement for SDC-45-1020, FPMB-BB20-10, P20-10BB | 4.5 x 10 Water Filter (4-Pack)

Q. What is this filter used for? A. This whole house sediment water filter is designed to help reduce fine particulate matter such as rust, dirt, silt, sand, and scale before water enters your home’s plumbing and filtration system. Q. What does 1 micron filtration do best? A. A 1 micron rating targets very fine sediment and is commonly used for sediment polishing when additional particulate control is needed beyond standard sediment filters. Q. What makes spun wound polypropylene effective? A. Spun wound polypropylene uses depth filtration to capture particles throughout the entire cartridge rather than only on the surface, supporting higher dirt-holding capacity and consistent filtration over time. Q. Where is this filter typically installed? A. This filter is commonly installed as a secondary or polishing-stage sediment filter, or as a first-stage filter only in low-sediment water conditions, to provide finer particulate control ahead of downstream filtration. Q. How often should a 1 micron filter be replaced? A. Replacement frequency depends on sediment load and water conditions. Because finer particles are captured more quickly, many households replace 1 micron sediment filters more frequently than higher micron options. Q. Does this filter improve taste or odor? A. This cartridge is designed for sediment reduction only and is commonly paired with carbon filters when taste or odor improvement is desired. Q. Will a 1 micron filter affect water pressure? A. A 1 micron filter is designed to capture very fine sediment, and pressure impact depends on water conditions and sediment load. Monitoring flow helps determine when replacement is needed to maintain performance. Q. Is this filter washable or reusable? A. This spun wound polypropylene sediment filter is designed for one-time use and is replaced when sediment buildup affects flow or filtration performance.

• 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.
