According to this article, masks can be reused (and critically, retain their electrostatic charge) by baking in an oven for 30 minutes at 160 F or steaming for 3-10 minutes (this article says 3, the CDC site says 10 I think): https://utrf.tennessee.edu/information-faqs-performance-protection-sterilization-of-face-mask-materials/ https://utrf.tennessee.edu/information-faqs-performance-prot... The CDC recommends not reusing masks, but sometimes it may be necessary. Another option is to have 5 masks in a paper bag and rotate them every day. The virus should be dead after 5 days. Another option I read is to steam a mask in the microwave using a plastic bag with 60ml (6 tbsp) of water for 3-10 minutes once steam is generated. https://www.cdc.gov/coronavirus/2019-ncov/hcp/ppe-strategy/decontamination-reuse-respirators.html https://www.cdc.gov/coronavirus/2019-ncov/hcp/ppe-strategy/d...
