OMNIFilter RS22 10-Inch Sediment Filter Cartridge — 5 Micron, Whole House

Overview

The Pentair OMNIFilter RS22 is a heavy‑duty, 10-inch sediment filter cartridge built to catch finer dirt in your water. Its design combines a durable polypropylene string wound around a rigid core, creating a larger filtration surface and improved dirt loading capacity. In real-world use, this translates to steadier water flow and extended intervals between changes when paired with compatible housings.

Designed for both municipal and well water, the RS22 is optimized for whole‑house filtration without compromising everyday usability. The cartridge’s construction and precise winding promote efficiency, making it a practical choice for households seeking economical filtration that reduces visible sediment and grit.

What it filters and how it helps

The RS22 targets fine sediment, including sand, silt, rust, and scale particles, reducing them to 5 microns in both chlorinated and non‑chlorinated water supplies. This level of filtration may contribute to clearer water and reduced sediment in taps and showers, though results can vary based on initial water quality and system configuration.

While this description highlights potential outcomes, it is not a medical claim. Use of the RS22 should be considered as part of an overall water filtration plan to address sediment and particulates in your home.
