water filters

I generally don't use a filter at all. The local water has to be potable, so I just use what they have. If we are at a site where the water has an objectionable smell, we use water that we carry in jugs for coffee, tea, and such. We drink bottled water. I've never had an ice cube that was objectionable.

Now on the other hand, a water softener might come in handy to protect the washing machine and things.
