Great idea about the MERV 13 filter in between 2 layers of cloth. Let me know if she sets up shop and starts selling them to the general public. I just purchased a mask from a lady on Etsy, but it’s just a simple cloth mask. Still, better than nothing.
I purchased one from Etsy that has a filter pocket. I’ve also seen suggestions for using vacuum cleaner bags as filters.
