GET SUNNY!
Another option would be to expose your contaminated masks to sunlight. The UV component in sunlight will kill viruses. And if you position the mask just right, as the sun moves across the sky it will irradiate the entire face of the mask without any part being shaded and untreated. (You could even hang your masks from a clothesline if you clip the clothespin to one of the tabs where the strap attaches to the mask proper.)
Unfortunately, for the Shepherdess and I and many other preppers, the weather here in Spokane does not cooperate with this strategy for much of the fall/winter season. It will be too cold, too cloudy, too windy or rainy or snowy to make sunlight sanitation work. And I don’t trust the moose either. But if you’ve got sunlight – put it to work!
Just don’t put the mask on the dash of your car – the lamination of the windshield will block most of the UV light. And if your side windows are tinted that too will block UV. You could make a little aluminum-foil-covered cardboard frame to hold the mask, and cover it with Glad or Saran wrap to keep the dust and bugs and bird poop out of it. Just make sure the frame doesn’t shade your mask!

ULTRAVIOLET (UV) LIGHT
Here’s what we know:
1. We’ve known for decades that ultraviolet light works, especially the higher frequency end of the band, UV-C. https://en.wikipedia.org/wiki/Ultraviolet_germicidal_irradiation Even at low power output, UV-C light tears the living daylights out of bacteria and protozoa and viruses (and you, and your eyes if you’re not careful, and pretty much anything living). https://www.americanultraviolet.com/uv-germicidal-solutions/faq-germicidal.cfml#germicidalLamps
2. “…for influenza virus, dozens of UVGI [UltraViolet Germicidal Irradiation] disinfection cycles could be performed on respirators without the UVGI affecting their performance.” The filter fabric begins to weaken against tearing (and weakens more the higher the UV-C exposure) but it doesn’t affect the filtering efficiency (until the fabric gets too weak and tears) and it doesn’t affect the head straps as much. Simply testing the fabric and straps prior to wearing the mask should be adequate. This seems to be the only downside. (1)Continue reading“When Do We Change Masks? – Part 2, by ShepherdFarmerGeek”
