We actually bought 2 UVC light bulbs just to sterilize my masks. We only have a handful, and believed early on that UVC could make them reusable, but have no proof.
But using them is very hard. They produce ozone which is harmful to your lungs, and the light themselves are harmful to your eyes and skin. So I don't have a safe way to set this up yet. Now that we are all quarantined maybe we can have more time to figure out a sustainable way to use it.
- chuckledog 7y agoBrowsing Amazon, it seems that there are some UVC bulbs that specifically avoid ozone creation. Other variants are marked “with ozone”, and for some reason both variants typically cost the same. I bought one “no ozone” and plan to put it in inside a reflective “pouch” (actually just a silver lined grocery carrier) for sterilizing things without exposing anything outside the bag to the UVC light.
- dillondoyle 7y agoI put mine on my back entrance which is basically open air. Close door with cord under it. Able to plug it in without being able to see it and ozone spews out to pollute my city even more.. Do you know how long of an exposure is needed to be effective? assuming within 2-3 feet but single source not even light
- jennyyang 7y ago30 mins at 8 feet distance. 10 seconds if within an inch from what I remember.
- chuckledog 7y ago@jennyyang did you make your UVC setup yet? Here is what I wound up with over the weekend https://twitter.com/choser/status/1241933729536200709?s=21 https://twitter.com/choser/status/1241933729536200709?s=21 I also found the system a bit hazardous and am treating it with more respect now. It seems pretty powerful even at 13W. I was sterilizing my masks for 2 hours, now am just doing one minute per side.
