Water filters

Like he said. Just do the water you drink rather than the whole camper. I think the little blue filters cut way down on delivery volume and pressure. I had a water Pur before but upgraded to RO. The water pur is a LOT cheaper.

I use a faucet-mount filter. It is a PUR mineral clear I bought from Costco for $39. It includes enough filters, 6, to last years of camping use. This should really help by no longer needing to take bottled water and gets rid of chlorine smell/taste as well as the garden hose flavor. I use an RV type hose and in-line filter to fill my water tank, but still I can taste that plastic/vinyl/hose in the water. Probably the tank itself.
I can tell you the PUR filter works great! I did a blind taste test with the DW. A plain glass of camper water, tap water, camper water though the filter, tap water through the filter, and bottled water of Safeway house brand of bottled water. Final result; filtered camper and house water tied for first. Bottled water second, house water 3rd and camper water last. This filter made the camper water go from last place to first.









Here is a link to a video about the filter and it's ease of installation;

Many filters give estimates of their lifespan. You can either replace it on a calendar schedule or estimate your usage and replace it based off of how much water you have put through it.

My system is a whole-house style filter where the city inlet is and an under-sink tap for the drinking water. The first one keeps the system clean and the smaller one achieves the bottled-water level purification.

As a rule of thumb, I'd replace it every 3 months, whether it needs it or not! They're inexpensive enough!

I change mine when the water starts tasting funny, or when I'm taking the whole house filter apart and see dirty water inside.
