One comment that I have read a few times in forums is that the ozone that discharges into the water breaks down to harmless levels almost instantly. Its the ozone that is released into the air that needs to run through a carbon filter. Would anyone be able to confirm this?

Not all that sure how much of an issue getting every last bit of this ozone is really. When I look online, I see many companies selling in home ozone generators that are spraying ozone into the home intentionally in order to reduce or eliminate cigarette smoke and other odors.
