I'm not a mask expert so I have to trust these are sufficient to stop the spread of the Covid 19 virus. They seem well constructed with single ear loops. There's a metal nose bridge forming strip built into the mask to conform to the users facial features. The mask expands to cover down to the lower chin. All masks N95, industrial and these will direct moist breath to condense on glasses in cooler weather. Not a defect just an observation wearing them as well. Take care out there folks. Stay safe.

Was good for intended purpose

Excellent! Got them for a hefty price when masks were out of stock elsewhere during the first Covid restrictions.

No problem with these masks. I would buy them again.

Great product… used it many times over the years
