The KF 94 masks supplied by Clear Pro Global are as excellent as the company that supplies them. I have reordered the masks several times this year. The mask are exceedingly well made, shaped and protective against the trifecta of circulating respiratory viruses, hypoallergic (previous non KF 94 masks caused mask rash and pimples), comfortable and breathable for long wear. Clear Pro Global fulfills their orders quickly and reliably, and their customer service team are excellent, super friendly and super efficient.
