Parker E23R20A String-wound Cartridge Filter 5 Micron

Product Description

The PARKER E23R20A is a string-wound cartridge filter designed for plumbing and water filtration applications. Constructed with a rayon winding over a polypropylene plastic core, it delivers depth filtration at a 5 micron rating, capturing sediment, dirt, and particulate from water lines before they reach downstream equipment or fixtures. The cartridge measures 2.5 inches in outside diameter and 20 inches in length, fitting standard big-blue and comparable filter housings. Materials meet FDA grade standards, making the E23R20A appropriate for potable water systems. It is installed by licensed plumbers and water treatment technicians in residential and light commercial settings.

This filter is suited for whole-house sediment reduction, pre-filtration ahead of softeners or reverse osmosis systems, and general point-of-entry water treatment. The 5 micron rating handles well water with moderate sediment loads and municipal supplies where line sediment is a concern. Its 20 inch length provides increased filter surface area and longer service intervals compared to standard 10 inch cartridges, reducing changeout frequency in higher-flow or higher-turbidity installations.
