RV/camping people typically have one because you never know what quality of water you're going to have at parks/campgrounds.
I don't really understand this. What we do is buy gallons of drinking water at the grocery store, then refill them at the water/ice stations that are all over the US. At 35-cents per gallon, you can have all the fresh pure water you want at a fraction of the time and cost of filtration systems. When a container starts wearing out or goes south for whatever reason, replace it for under a buck.
Do you have a water filter, and why?
