It's interesting to watch the CDC evolution from no public masks, to recommended public masks. Currently the CDC recommends health care workers wear an N-95 fit-tested mask, washable face-shield and non-sterile cover gown, with lots of emphasis on
donning and doffing. Might be more economical and safer to use gloves intended to be reused, along with a washable face shield, and a washable cotton mask for maximum sustainable protection.
