Parker M23R20A String-wound Cartridge Filter 5 Micron

Product Description

The PARKER M23R20A is a string-wound cartridge filter designed for plumbing filtration applications requiring reliable sediment and particulate removal. Built from polypropylene cotton with a polypropylene plastic core, this filter measures 2.5 inches in outside diameter and 20 inches in length, fitting standard housings used in residential and light commercial water treatment systems. The 5-micron rating captures fine sediment, dirt, and rust particles before they reach downstream fixtures or equipment. The FDA-grade material construction makes it suitable for potable water service. Licensed plumbers and water treatment technicians are the primary installers of this cartridge type.

This filter is used in point-of-entry and point-of-use plumbing filtration systems where sediment control is required upstream of water heaters, softeners, reverse osmosis units, or fixtures. The string-wound construction provides graduated density filtration, which improves dirt-holding capacity compared to flat-media alternatives. It is suited for residential whole-house filter housings and light commercial applications with compatible 2.5-inch OD, 20-inch standard housings. Maximum operating temperature is 120 degrees F, which should be verified against the application before installation.
