On my new camper, the documentation refers to, in between trips, taking the water filters out, drying them, and then placing them into a plastic bag in the fridge.
(I have the platinum 'freshly Squeezed water company' RV setup).
I understand the reasoning (not grow bacteria sitting in the filter while it is sitting in water for a length of time) but interested how many of you actually do this, and what do you consider a reasonable amount of between trips for you to warrant doing this...
