I'm sure that the lung cancer you will get from the ozone will offset the miraculous lack of asthma/hearing loss. Rule one of taking care of yourself around hazardous substances: Thou shalt not pump electrically active substances(be they strong acids, bases, ozone, etc) into your body. Ozone is not responsible in any way for elevation sickness, but it is the reason that if you go up to, say, mt Mitchell(highest peak east of mississipi), you find yourself in a dead forest from 1000 feet below the top. Ozone is poisonous and as any gas that leaves an electron behind in your lungs(uses your lungs as a catalyst to reverse the process that blew them through the purifyer), is cancerous. Miles up in the air, it absorbs radiation that would otherwise hit us, but any direct contact with ozone is dangerous. I looked into using a quadra for silent case cooling, but any intake would either corrode or short(relatively unlikely) the circuits in my motherboard.
BTW: All ionic breeze products(air purifiers that work without moving parts) take negative ions in the air and pulse electricity to combine them into O3. THEY ALL EMIT OZONE, I REPEAT.
