The Tier1 P1-20 is a 1-micron spun polypropylene sediment filter, making it ideal for trapping fine particles such as dirt, silt, sand, rust, and scale. Its tight 1-micron rating provides superior pre-filtration, protecting downstream filters, reverse osmosis membranes, and household appliances from premature wear caused by sediment buildup.

The Tier1 P1-20 is a direct comparable replacement for the Pentek P1-20 sediment filter. It measures 20 inches in length by 2.5 inches in diameter, making it compatible with most standard Big Blue-style and 20-inch whole-house filter housings that accept 2.5" x 20" cartridges. Always verify your housing dimensions before installation.

The Tier1 P1-20 has a typical service life of up to 6 months, depending on your incoming water quality and daily usage. Homes with well water or high sediment levels may need to replace the cartridge sooner. A noticeable drop in water pressure is a clear indicator that it’s time to install a new P1-20 cartridge.

The Tier1 P1-20 is constructed from 100% pure melt-blown polypropylene with no chemical binders, adhesives, or surfactants, ensuring safe use with potable water. The materials used in the P1-20 meet FDA requirements under Title 21 of the CFR for food-grade contact, delivering reliable and clean sediment filtration for residential and light commercial applications.

The Tier1 P1-20 is a mechanical sediment filter engineered to reduce particulate matter down to 1 micron, including sand, silt, rust flakes, dirt, and scale particles. While it does not remove chlorine, lead, or chemical contaminants, it serves as an excellent first stage of filtration and extends the life of carbon filters and RO systems installed downstream.
