Undoubtedly, one study performed in 2019 showed that a surgical mask was as reliable in protection from breathing viruses as the N95 mask in numerous clinical settings in the US.
The US Centers for Illness Control and also Avoidance (CDC), however, still recommends N95 masks be put on by Health care Employee (HCP) that are available in contact with prospective providers of SARS-CoV-2.

In two research studies in Beijing it was revealed that putting on an N95 respirator can be very reliable in stopping the damaging impacts of breathing in PM2.5 particulate issue.
Using a N95 mask lowered mean arterial pressure as well as raised heart price irregularity contrasted to not using a face mask when exposed to air pollution.
