Speaking of ozone, and I've made lots of it before from HV, but those Air Ionizer purifiers that have like a 7kv spark make ozone, and that can't be healthy either. I wonder if the UV lamps make more ozone than those ionizers? Ozone has a weird sweet kind of smell to it. But it's not stable and I'm sure breathing in that smog is bad...
EDIT: after going to the link Photon Wrangler posted, I was right the Ionizer air purifiers produce a lot of Ozone. I always thought those things would be more unhealthy than good. :green:
