Right now we're using a service and they suck. Almost every month they either don't show up or don't deliver the right number of bottles. How hard could it be to get that right? ####### idiots. Plus it's not exactly cheap, it's a pain the ### to deal with storing all the bottles & empties in the garage, lugging them into the house, then having the huge machine in our kitchen, etc.
I bought
this ultrafiltration system. I went with it over RO because RO actually wastes some water in the process of making clean water, and the better systems have up to 7 cartridges to replace. Ultrafiltration isn't quite as good as RO but it's good enough imo.
I bought a TDS meter. Our tap water reads 51 (pretty good for tap water), and our bottled water reads 20. I'll post an update when I get around to installing my system since I can tell you guys are riveted.
