not sure, but I've been using water from an RO water machine that sits in the local Wallmart's, all of the Wallmart's up here in Dallas have them, I've been using it for about a year now with no problems and it's only .33 cents a gallon, they have a booklet that shows the water going through an RO/DI machine and then through a laser, so it should be fairly clean...
