I used to do OSHA Hazardous Waste training and have probably fit tested over a thousand people and I’ll tell you the paper masks are worthless. They are dust masks. The N95’s won’t stop a virus. If you want to protect yourself from Covid with a mask it’s going to cost you. And if it isn’t fit tested for proper fit even a good one is worthless.
Yup. basically you need a’PAPR with separate air supply or you are kidding yourself. The N100 may work not sure
