Parker M11R20A String-wound Cartridge Filter 50 Micron

Product Description

The PARKER M11R20A is a string-wound plumbing cartridge filter designed for sediment removal in residential and light commercial water filtration systems. Built from polypropylene cotton wound over a polypropylene plastic core, it measures 2.5 inches in outside diameter and 20 inches in length. The 50-micron rating targets coarse sediment such as sand, silt, and rust particles. FDA-grade materials make it suitable for potable water applications. Licensed plumbers and water treatment technicians are the primary installers, though knowledgeable service pros working on whole-house or point-of-entry filter housings regularly handle this cartridge.

This filter cartridge fits standard filter housings that accept a 2.5-inch OD, 20-inch string-wound element. It is commonly installed in whole-house sediment pre-filtration systems, well-water treatment setups, and irrigation pre-filters where coarse particle loads are a concern. The polypropylene cotton string-wound construction provides graduated density filtration, helping extend the life of downstream finer-rated filter stages. Maximum operating temperature is 120 degrees F, making it appropriate for cold and cool water lines but not hot water supply lines.

Installation Notes

Installation and replacement should be performed by a licensed plumber or qualified water treatment technician in accordance with local plumbing codes and IPC guidelines. Shut off the water supply and relieve system pressure before opening the filter housing. Inspect housing O-rings for wear when changing cartridges, and do not exceed the rated 120 degrees F operating temperature on the supply line. Dispose of spent cartridges per local waste regulations, as they may contain captured contaminants.
