Frequently asked
The sealed UV-C units I compared are safe because the lamp is fully enclosed. Avoid open UV-C wands or fixtures that expose skin and eyes to the bulb.
Properly designed UV-C purifiers using 254 nm bulbs produce minimal ozone. I avoided any unit with a 185 nm bulb because those create ozone as a byproduct.
