Can a kn95 mask protect you from covid 19 if fitted tightly on face?
I have a kn95 mask I water test it and it doesn’t leak will this protect me from getting covid 19? I also have goggles and face shield do I need to wear them as well?

The mask provides a very high level of protection if its worn properly and if you and everyone else at work follows the rules. You can use a face shield alone or with a mask underneath; or you can wear a face mask alone or with googles.
