Thank you so much for describing your experience with the Waterwise. Is it very noisy, or just a quiet fan?
We need more water than the 4000 can produce, so I was looking at other models, like the 9000, but they all seem to be the same size - I can't tell the difference by their description. I'll call the company today & investigate.
I think this is what we'll get - I've been looking at all kinds of filters, and distilled seems best.
