Fran, someone mentioned “filti” fabric for filters on another discussion group (https://filti.com/product/filti-face-mask-material/ <https://filti.com/product/filti-face-mask-material/>). There is debate on whether it is washable - their Facebook page says washed up to 8x before loosing effectiveness in one place, and in another that it should be “steam baked” in your oven to kill any virus on it. But that it is very effective in filtering small virus particles. Honestly, I think it is overkill for the home going out occasionally market, but might be very helpful if in a likely exposure environment (I’m thinking if I get on an airplane any time in the next couple of years, for example) or for someone very immune-compromised… I have one friend who got hers and did machine wash it and said it survived fine… time will tell. Not sure how it will work out - I ordered the smallest quantity to try out and see. Still not sure if I will sew it into some or just use it in a pocket as a filter.. -Megan
