Built from FDA-grade polyester with a polypropylene plastic core, this filter measures 2.5 inches in outside diameter and 20 inches in length, offering a 1 micron filtration rating for fine particulate removal. It is rated for continuous service at water temperatures up to 120 degrees F. Licensed plumbers and water treatment technicians install this filter in standard filter housings as part of point-of-entry or point-of-use filtration systems.\u003c\/p\u003e\u003cp\u003eThe S39R20A is suited for residential and light commercial water filtration setups where sediment control at 1 micron is required. It fits into common 20-inch big-blue or standard filter housings used in whole-house pre-filtration, process water lines, and general plumbing supply protection.
