A new type of coronavirus (COVID-19) struck, and “masks” were sold out overnight, making it hard to buy with money.
At the same time, we recommend the 10 best face masks selection for everyone.
10 Best Face Masks
There are many specifications and standards for masks. Generally, masks are divided into medical masks and protective masks.
Medical masks are divided into three levels, ASTM Level 1, ASTM Level 2, and ASTM Level 3. This standard is formulated by ASTM (American Society for Testing and Materials).
Among them, Level 1 and Level 2 masks usually become Procedure Masks. Level 3 masks can be used in the operating room, also called Surgical Mask, which have better protection performance.
Protective masks are divided into N95 / N99 / N100, P95 / P99 / P100, R95 / R99 / R100.
This standard was developed by NIOSH (National Institute for Occupational Safety and Health).
In general, it is recommended to wear Level 1 or Level 2 masks in daily public places to protect against bacterial and viral infections. The filtering effect on bacteria reaches or exceeds 95%.
Unless you need to go to a more dangerous or densely populated place, you need to wear a higher level mask, such as N95.
