Well, it seems that the tank wouldn't last that long, the 240L one I saw on the Logevity Resources Model, and it sounds like I'd be filling up the tank all the time which could get expensive and annoying. I'm looking for something that doesn't release contaminants into the stream, something that I could use for Ozonating Water for drinking, Ozonating Olive-Oil and the air in my bedroom every so often.
How does Air and Oxygen fed units compare in terms of effectiveness, quality, price for filling the oxygen tank, etc?
