No issues

Bought these pricey masks before flying in August.
They were well sealed in plastic. Harder to breathe in compared to the cheaper level one surgical style. So they seem more robust in my opinion.

These masks are thick, but breathable. Ear loops are sturdy – have never had one break on me. The nose clip allows for a very good fit around my nose – if I get to talking too much with the mask on, it sometimes still slips down, but that is somewhat unavoidable with any mask. I’m not a medical professional, although my wife is an ICU nurse and even she has remarked how good these masks seem. Short of finding an actual N95 mask, it seems like you can’t really ever be completely sure about the quality of a particular mask, but these masks really do seem like they provide a better degree of protection than cloth masks or other cheap disposable masks. I highly recommend these masks

I rarely write reviews, but I had to on this one. I was hesitant to order the masks at first, but desperate to find a good level 2 mask before going back to work. I was so happy I did and just ordered a second box. They fit my larger round face. I can bend the plastic around the nose perfectly so it doesn’t fog up my glasses. I can also bend the sides in to form my face and not allow any gaps. Even with asthma, I can breathe through it for all 8 hours of my work day. Would definitely recommend! Please don’t run out!
