ro or ro/di

[jws444]

The deionization stage is needed if you want a trouble free water source. Not only that, if you tell Ed from aquasafe to give you a unit that doesn't come with a deionization chamber, you'll be saving 10 bucks at the most!? I don't see any point in doing that. My bet is that he'll force to you pay the shipping. He generally doesn't allow pick ups. I guess some of his shipping subsidizes his ro/di units. They are still a great value regardless.
