Premixed water from big als warning**

If you want a cheap RO/DI unit look at Aquasafe. They are in BC and you can order from them direct but they also sell on Ebay for cheaper. I got my unit with 5 sets of filters and a TDS meter for $100 but that was awhile ago. It doesn't take long to make your money back especially when you factor in your gas to go pick up RO water as well.
