This Watts replacement cartridge is rated to 1-micron absolute filtration, removing fine sediment from your fresh water supply before it reaches your RV's plumbing. It's sized to fit the Flow-Pur exterior water filter system, which mounts outside the coach on the incoming water supply hose so it filters everything heading into the RV.
Swap it in whenever your existing cartridge is due for replacement to keep water pressure and clarity where they should be.
Replace on a regular schedule for consistent water quality throughout the season.
