Hi Cee-it. I don't know which companies you were involved with, but there are others operating on that small of a scale who are still doing just fine. Realitive to your thoughts about the destructive elements of Ozone, I beleive all of your information is wrong. Perhaps your other companies were using some kind of corrossive agent in their mix, but MZEI has done hundreds of tests on everything from picture paintings, to computers, to electrical wiring, wallpaper, to sheetrock, to practically every surface in existence with ABSOLUTELY NO CORROSSIVE effects whatsoever. That's one of the main reasons our ozone treatment makes sense. Furthermore ozone is not deadly to humans - as is popularly thought. True, in strong quantities it can irriate your lungs, but that's about it. MZEI has come up with a de-ozone tenchnology that is used in the protocol with the ozone part of the AsepticSure that completely returns the room to 100% normal levels of O2 after all pathogens are eliminated - AND ALL of this is done in less than 90 minutes.
