One of the highest medical face mask quality with 94.9% bacterial filtration efficiency (BFE) in Microbiological test. Factory using N95 manufactured technology combine with high material quality for each layers such as: fiber Melt-Blown polypropylene, nonwoven fabric, ES fabric, VN95 Complete with reliability equal N95 and 3M mask.
This is the first choice for outside safety when The Centers for Disease Control and Prevention (CDC) does not recommend that the general public wear N95 respirators and cede for hospitals.
As for the quality, it seems a decent surgical mask (not a N95 mask). The elastic straps have just the right tension for the average adult head. I received in 3 days, how fast it is. Highly recommended
