- HarryHirsch 7y agoProbably no reason for concern. The bog-standard germicidal lights emit UV at 254 nm, but to generate ozone you'd need vacuum UV at 189 nm. You'd expect this to be filtered out, precisely because of the health hazard. That said, I'd be concerned around photocopiers. If you can smell ozone it's definitely above occupational exposure threshold. In a previous workplace I kept telling our secretary just that, but she wouldn't listen.
- Someone1234 7y agoThere's two types of UV Air Filters, based on UV-A and UV-C. UV-A systems don't produce much ozone (but sometimes the bulbs are imperfect and produce a trace amount). Ozone is produced by ultraviolet light in the 160–240nm range, meaning UV-C. If you have a UV-C based UV Filter I wouldn't call that ideal but at least you're still receiving less than a ozone generator or even an ioniser both of which would produce higher ozone levels. You may still wish to crack a window occasionally and look at a HEPA filter next major upgrade cycle.

- hedora 7y agoAre you sure it isn’t (also) electrostatic? Those definitely produce ozone, and should be avoided, apparently.
- verelo 7y agoYeah it's for sure a UV bulb, installed it myself. Honeywell product.
