How much water will you be using? For small quantity just go buy it, as making small amounts of water and then stopping is hard on the filters. Filter cost depends on the number of stages you have.
I have a 70 Gallon tank...not set up as I am moving. I was just thinking for the new house what would be more cost effective. How long can RO water sit without being used? Does it go stale?
