Parker 39R20 Cartridge Filter 1 Micron 20 Inch Cotton

Product Description

The PARKER 39R20 is a string-wound cartridge filter designed for plumbing and water filtration applications. It measures 2.5 inches in outside diameter and 20 inches in length, with a 1-micron rating that captures fine sediment and particulate from water systems. The filter body is constructed from FDA-grade cotton wound over a tinned steel core, supporting clean-water applications where material compliance matters. It handles water temperatures up to 250 degrees F, making it suitable for both cold and hot water service. Licensed plumbers and water treatment technicians install this filter in residential and light commercial inline filter housings.

This filter is suited for inline sediment filtration in potable water supply lines, well water systems, and industrial process water lines. The 1-micron rating targets fine particulate including silt, rust, and fine sand. FDA-grade cotton construction makes it appropriate for drinking water and food-service water supply applications. It fits standard 2.5-inch OD filter housings designed to accept 20-inch cartridges, a common configuration in whole-house and point-of-entry filter assemblies.
