Check with a neighborhood or local DDS, I am sure they would sell you a box or a partial box of disposable face masks or even just give you a few. And maybe inquire about some disposable gloves too (just to have on hand). I use disposable gloves when i need to roll or mix meat as in meatloaf or meat balls or roll cookie dough or cut hot peppers.
I have had those days too where the window must have been open and knowledge and skills flew out.
