Parker E39R20A String-wound Filter 1 Micron 20in Rayon

Product Description

The PARKER E39R20A is a string-wound cartridge filter designed for plumbing and water filtration applications requiring fine particulate removal down to 1 micron. Constructed with a rayon winding over a polypropylene plastic core, it measures 2.5 inches in outside diameter and 20 inches in length. The rayon media meets FDA material grade standards, making it appropriate for potable water and food-service-adjacent systems. This filter fits standard 20-inch Big Blue and comparable filter housings and is installed by plumbers or water treatment technicians in residential and light commercial settings.

The E39R20A is suited for whole-house filtration, point-of-entry water treatment, and process water applications where sediment, silt, and fine particulate control is required. Its 1-micron rating provides tight filtration for systems where downstream equipment such as reverse osmosis membranes, UV disinfection units, or sensitive fixtures demand low sediment loads. The FDA-grade rayon construction makes it an appropriate choice where material compliance is a consideration.
