What kind of mask should be used during the COVID-19 pandemic?
Masks and respirators can provide varying degrees of protection, with well-fitting NIOSH-approved respirators (e.g., N95s) offering the most protection.

Therefore, it’s important that you always choose a well-fitting and comfortable mask or respirator and wear it properly (covering your nose and mouth).

Does a PM 2.5 filter for masks help with preventing the spread of COVID-19?

Some masks have built-in pockets in which one may place a filter. Data on the use of additional filters is limited.
Are respirators effective against the coronavirus disease?
N95 respirators offer a higher level of filtration than cloth, surgical or procedural masks. However, they are not necessary to protect people from the virus under normal circumstances.
