I have been having "spring" water delivered to the house for more years than I can remember in those 5 gal jugs. It works fine, and tastes great.
I just noticed this Zuvo add in this month's Popular Science which looked interesting, but wondered what people like to use.
Let me also say that for me to switch away from the bottle deliveries which averages about $58/month (5-6 jugs), my primary concern is wanting on demand, excellent tasting water with a minimum of hassle, and that doesn't take an hour to fill a coffee pot.
I know there are all those brands out there like Brita, Pur, etc. but I don't really know much about them. I don't give a crap about all the plastic bottle environmental nonsense or some gimmick catch phrase like being "sustainable." I just want something that is easy and works.
