Ozone causes and exacerbates lung damage.  It is a serious pollutant.
We have that info from two pulmonologists and multiple allergists (two
older relatives with lung damage, one being an aunt who recently died of
COPD, and multiple family members in 4 states with allergies), but you
can find it on a lot of reputable sites including EPA ones.  What are
recommended instead are Hepa filter air cleaners.  Why do people use
things that generate ozone such as ozone generators and multiple types of
ionizing air "cleaners"?  Because it smells good, like after a rainstorm.
Years ago -- many years -- there was an ozone generator on many high end
driers and those were dropped because even though that was before it was
common for many people to be litigious there were enough stay home moms
who took lung damage from the ozone so the medical suits became too
costly.  Remember the driers which promised "rain storm fresh" smell?
People just plain hardly ever sued companies back then, but that one was
serious enough that the suits changed corporate policies -- which is
typically how such changes take place in the U.S. instead of things
that don't fit neatly into any over-sight category being banned.
 
Ozone in the lower atmosphere is such a serious pollutant that there
are websites where those with lung damage or those who have vulnerable
family members like infants can follow the daily levels.
 
For example:

Have you acquired asthma since you got your ozone generator or does it
vent enough?  If not, you still may.  Sorry about being blunt, but this
is a potentially serious enough thing that I figure I'd better so that
you at least check into it some more.  Pulmonary health is often a
longevity limiting factor (i.e. determining how long an individual will
live) and can be a cause of sudden death as well as certainly badly and
painfully undermining quality of life for a number of individuals.
Putting an ozone generator in a home is kind of like purposely drinking
wine from a carafe with lead in it because it makes wine sweeter.  Not
a good life choice to choice to add the primary constituent of smog to
one's home.
