Why you should have a filtration system on your RV..

We spend 4 months in AZ near the Coloriver. Water is horrible. After 3 days our filter would Look like the pic of the OP filter. We rent a water softener and it is placed ahead of the filters and looks like new at the end of 4 months. Still won't drink the water but if you don't filter and soften the water you get lime stains everywhere and plugged faucet screens. Not to mention what it does to your hair.
