Mask with filter, reusable/ washable

So I have never been in the business of selling snake oil, and with a massive pandemic at hand, stay at home orders, and basic necessities unattainable, I decided to look into making masks. Materials are super scarce and some people are resorting to additional pieces of fabric to create a filter..... this doesn’t really work and leaves the consumer with false hope. These have an actual Filter interfacing sew in between to make them reusable, can be sanitized in microwave for 15 seconds.
