Tier1 5 Micron 20x2.5 Water Filter | Spun Wound Polypropylene Whole House Sediment Cartridge | Replacement for Pentek P5-20, 155016-43, SDF-25-2005 | 2.5 x 20 P5-20 Water Filter (3-Pack)

What is this filter used for? This whole house sediment water filter is used to help reduce common particulates such as sand, rust, dirt, and silt before water enters your home’s plumbing system. What makes spun wound polypropylene different from other sediment filters? Spun wound polypropylene uses depth filtration to capture particles throughout the entire cartridge, not just on the surface, which supports higher dirt-holding capacity and more consistent performance over time. Will this fit 20 x 4.5 or heavy-duty housings? Yes. The 20 x 4.5 inch size is designed to fit most standard and heavy-duty whole house filter housings that accept 4.5 x 20 water filter cartridges. Is 5 micron a good choice for whole house sediment filtration? For many homes, a 5 micron rating provides a balanced approach by reducing fine sediment while still supporting typical whole house water flow. Where is this filter installed in a whole house system? This filter is commonly installed as a first-stage or entry point sediment pre-filter on the main water line for well water or municipal water supplies. How often does this filter need to be replaced? Replacement frequency depends on water conditions, but many households replace whole house sediment filter cartridges about every six months or when a noticeable drop in water pressure occurs. Does this filter improve water taste or odor? This cartridge is designed for sediment reduction only. For taste or odor concerns, it is commonly used alongside a carbon filter as part of a multi-stage filtration system.

• COMPATIBLE REPLACEMENT MODELS – Designed to fit standard 20 x 4.5 whole house filter housings and a replacement for Pentair DGD-5005-20, Liquatec SDF-45-2005, 155358-43, SDC-45-2005, AP810-2, P5-20BB, FP25B, FPMB-BB5-20, DEV910837, C155358-43, ClearChoice 84644, CMMF0520-45W1, MBGC-45200-05, SDG-45-2005, and VX05-20BB; suitable for most 4.5” x 20” water filter housings.
• 9 MICRON DEPTH SEDIMENT FILTRATION – Spun wound polypropylene construction captures particles throughout the cartridge depth, helping reduce rust, sand, silt, dirt, and scale commonly present in well water and municipal water systems.
• HIGH DIRT HOLDING CAPACITY DESIGN – The graded density structure traps larger particles on the outer layers while finer particles are captured deeper inside, helping support consistent flow and longer service life compared to basic surface 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.
• IDEAL WHOLE HOUSE PRE-FILTER – Commonly used as a first-stage or main entry point sediment filter to help protect plumbing, appliances, water softeners, and carbon filters from sediment buildup and premature wear.
