FILSADAE RV Water Filter KW1 Replacement for WaterPur RCS/FR1 (Set of 2) – Not for FRE-10-GN

Overview

The FILSADAE RV Water Filter is designed as a straightforward replacement for WaterPur KW1 cartridges used in RCS and FR1 housings. This set of two cartridges is ready to swap in, helping you maintain filtration without changing your existing system.

Filtration media and expected results

Each filter uses high-quality certified coconut shell carbon to help reduce sediment, rust, and odors, while targeting larger particles that can cloud water. In everyday use—whether you’re refilling a pitcher, brewing coffee, or cooking—this filtration can contribute to clearer, more consistent water flavors and a smoother mouthfeel.

Because the media is designed to address multiple particulates, you may notice water that looks crisper and tastes more balanced after a swap in a WaterPur KW1 setup.

Usage and maintenance

Under normal household conditions, replacement is recommended after about 10,000 gallons of treated water. The double O-ring seal helps minimize the risk of water bypass, supporting a reliable filtration cycle and reducing the chance of leaks around the cartridge during use.

These cartridges are replacement options for FR1 and RCS housings, making it easy to stay within the same filtration family without changing your system design.

Compatibility notes

Important: Do not replace PRE-10GN cartridges with this kit. The FILSADAE KW1 replacement is not built for the PRE-10GN line, so verify your setup before purchasing or swapping cartridges.
