Parker E39R10A String-wound Filter 1 Micron 10 Inch Rayon

Product Description

The PARKER E39R10A is a string-wound cartridge filter designed for plumbing and water filtration applications. It features a rayon winding over a polypropylene plastic core, providing a 1 micron filtration rating suited for fine particulate removal. The cartridge measures 10 inches in length with a 2.5-inch outside diameter, fitting standard filter housings used across residential and light commercial water treatment systems. At 0.4 pounds, it is a lightweight drop-in replacement. The FDA-grade material construction makes it appropriate for potable water service lines. Licensed plumbers and water treatment technicians are the primary installers of this cartridge.

The E39R10A is used in inline cartridge filter housings for point-of-entry or point-of-use water filtration systems. Its 1 micron rating targets sediment, fine particles, and suspended solids in supply lines. The rayon string-wound construction creates a graduated density from outer to inner layers, improving dirt-holding capacity compared to flat-media cartridges. Typical applications include pre-filtration ahead of water softeners, carbon filters, UV systems, and reverse osmosis units in residential and light commercial plumbing systems.
