For a great value, does what it says on the tin RV water filtration system, then it is worth giving the Inline RV water filter from PurePlus a go.
This straightforward-looking dual cartridge inline system has a lot of the spec you would find on more expensive models and although it does have a 120-day capacity, there’s enough to see you through the camping season. The natural coconut shell activated carbon filter grabs particles, chlorine, pesticides and heavy metals from your RV’s water supply and the integrated KDF makes light work of bacteria and bugs. They can lose a little pressure at times, but you do get nicely filtered, clean tasting water for drinking and cleaning. They also come with a 90-day warranty for extra peace of mind.
