Rotate between your three masks. They recommend 3 to 4 days of air drying and any virus on the mask will be destroyed. I’m guessing after a day or two is okay. But I wait three days if I can.
Or - place on a wooden board or hang by a wood clothespin in your oven. They recommend 200 degrees for 30 minutes. I think 170 degrees for 15 minutes is okay.
Thanks for the info
I did some research. Besides your oven method for killing the virus, you can steam the mask for 10 minutes. I have a perfect size pot with 2 handles that I can hang the mask across the pot. Add water, boil for 10 minutes, and then let the mask dry..
