OMNIFilter RS1 Sediment Replacement Cartridge – 10in x 2.5in, 20 Micron, Pack of 2

Overview

The OMNIFilter RS1 sediment replacement cartridge is built for standard 10" x 2.5" whole-house housings. Its pleated cellulose media, wrapped around a rigid polypropylene core, captures a wide range of particulates—dirt, sand, silt, rust, and other sediment—down to 20 microns. By reducing these materials at the source, you can experience less visible buildup in taps and appliances and a smoother overall water experience at home.

Why choose the RS1

The pleated design increases the filtration surface area, delivering greater dirt-holding capacity and more consistent flow over the life of the cartridge. With a 15,000-gallon capacity, each cartridge typically covers several months of use, depending on water quality and household demand. This combination of higher capacity and durable construction helps maintain steady water pressure while protecting plumbing and fixtures from sediment-related wear.
