Keep your EVO X2 dual-stage RV water filter running at full efficiency. The Camco 40637 spun polypropylene sediment cartridge replaces the first-stage filter element, pulling sediment, dirt, and particulates out of your water supply before they can reach and clog the downstream carbon block stage.
The Camco 40637 is the factory-matched replacement sediment cartridge for the Camco EVO X2 Dual Stage Premium RV Water Filter Kit. In a dual-stage setup, the sediment filter is always the first element water passes through. Its job is to intercept rust, sand, dirt, pipe scale, and other suspended particulates before that water reaches the carbon block cartridge.
Skipping sediment filter replacement -- or running a spent cartridge -- forces your carbon block to do double duty and dramatically shortens its service life. Swapping this cartridge on schedule is the single most cost-effective maintenance step in a two-stage RV filtration system.
Captures sediment, sand, rust, and pipe scale particles 5 microns and larger before they reach the carbon stage.
Gradient-density construction traps particles throughout the depth of the media, not just on the surface, for longer service life.
Fits EVO X2 housings and most other canister-style filter housings using the 2.5 x 10 inch cartridge standard.
Extends the usable life of the companion carbon block cartridge by intercepting sediment load upstream.
A spent sediment filter increases pressure drop across your system, reduces flow rate to your RV faucets, and allows fine particles to reach the carbon block. Most RV users replace this cartridge every 3 months or after roughly 500 gallons of throughput -- whichever comes first. Heavy use of campground water with visible sediment may require more frequent changes.
This cartridge's 2.5 x 10 inch dimensions are an industry-standard size. It is compatible with any canister-style filter housing designed for 2.5 x 10 inch cartridges with a standard center post. This makes it a versatile replacement option for other brands of RV, marine, and whole-coach inline filter housings -- not just the EVO X2 kit.
If you own the Camco EVO X2 Dual Stage Premium Water Filter Kit, this is the sediment cartridge you need for routine maintenance. The EVO X2 system uses two separate housings -- one for sediment, one for carbon block -- and the cartridges are not interchangeable between stages. The 40637 is the sediment-stage cartridge only.
Spun polypropylene (also called melt-blown PP) is a food-safe thermoplastic fiber spun into a tight matrix around a center core. Unlike pleated filters, a spun PP cartridge has a gradient density -- looser on the outside, tighter toward the core -- so it traps large particles in the outer layers and finer particles deeper in. This distributes the sediment load through the full depth of the media rather than caking it on one surface, which extends filter life and maintains flow rate longer between changes.
