Thanks for the input Dave...
It would only be a minor addition to his product lines. (more of an area
of personal interest - water treatment.)
As far as getting sued - He wouldn't violate valid patents. (or invalid
ones with out a right to practice opinion)
He has a very solid background in diffuser technology ... .and some
interesting results and stories.
I'm pretty sure I don't have all the details right ;-). - I shouldn't
relay second hand information, but It sounded like an area of interest
for both you and my friend.
If you're interested - I can give you contact information - it sounds
like you two might have a pretty interesting discussion.
(he loves technical banter)
O3 is a lung irritant. Every Gov regulating agency has ppm per hour
limits for exposure for o3. Ozone Generators easily surpass the max
saftey limits. Read up on o3 before you leap. Start with the EPA and
Google Ozones harmfull effects - o3 exposure limits. True Generators
can easily overexpose a room with ozone.High o3 fries lungs

I was involved in some experiments years ago with removing the odor of
cigarettes from 'no smoking' rooms in hotels. Seems that maintaining
10 ppm ozone for a few hours got rid of most odors without a lot of
damage to fabrics and so on. I think it may not have succeeded
because, well, 10 ppm is a LOT of ozone, dangerous in even short
exposures, and the people that will work for hotel wages are just not
well enough trained to work with something that nasty.
The low levels of ozone made by the home ozone industry likely won't
help much with the odor, but they will, over time, damage materials
and possibly cause an asthma-like irritation.
The ozone machine has to have a reflexive control on it to maintain
ozone levels at 10 ppm too, which ups the cost a lot. We worked for
some time on a sensor for that, but most companies investigating the
deodorizing application gave up on it, as far as I know, and went into
water sterilizing instead. Liability concerns may have had something
to do with it.
I have been told that ozone generators work by desensitizing your
nose, rather than actually reacting with the odor source.
I have not been able to find the source for that statement though it

Both are true. When I worked around ozone without enough ventilation,
I could detect it only by the itching in my throat and a dry sensation

I can tell you that a surprise blast of 30% ozone in the face is no
fun at all, and it was a week or more before my throat and nose
completely recovered. Luckily I didn't inhale.
But it readily destroys some organic compounds, or and renders others
sufficiently polar that they are no longer volatile. It's so reactive
that you can actually measure a concentration gradient between the
center of a room and positions adjacent to the walls.
I know that it works well on residual cigarette stink, and not very
well on dead animal stench. Other odors may vary.
Saying that a microwave cooks from the inside out sounds
reasonable, too. It still is not true.
Yes ozone will desensitize your nose... to the smell of ozone.
Enough of it will have other physiological effects as well.
Ozone will not *quite* pass from point of generation to either
double carbon bonds or less-than fully oxided sulfur without
passing through points in between. But it will come very close

And yet I've seen it be quite effective on a mildew smell in a space
large enough there is no chance it was really removing the odorant.
So I have to believe the desensitization is a bit more general than
