I do believe it's time for a little 'afternoon delight', which at 74.5 equals nap.The size of the covid-19 virus ranges between 0.06-0.14 microns (1 micron is one millonth of a meter). An N95 mask is rated for 95% of particles, 0.3 microns or larger. This means that the covid virus can get through an N95 mask. It's like driving through a garage door entrance that's twice as large as your vehicle.
Can the N95 mask be useful, yes. Is it effective against other bugs, yes. Should you be confident that an N95 mask is completely screening the covid-19 virus, absolutely NO.
Same with HEPA filters. They have different levels of effectiveness in screening viruses depending in their HEPA rating. The very expensive better ones can screen the covid-19, not all can.
Wash your hands, keep them off your face.

Gave all my work clothes to goodwill.
