Due to a natural phenomenon called Brownian motionsuch minute particles don't travel in straight lines. Instead they bounce around in a zigzag fashion and are easily caught in the N95's electrostatic filter. While some experts are calling for a nationwide rollout of N95 maskssuch masks are currently reserved for link care professionals on the front lines of caring for Covid patients. That's partly due to a shortage of such masks, which are designed to be worn once and discarded, but also due to the training needed to fit and wear the mask properly.

Note: Beware of N95 masks with exhalation valves in them, since those valves put your airflow back into the environment. Also beware of knockoff N95s being sold on the internet and at some commercial stores.
