You'd better not let someone sitting next to you breathe, or cough, or sneeze then. When I'm using my CPAP, my mouth is closed and I'm asleep. I'm breathing through my nose, which has hairy filters in it, plus a mask that has a filter on its exhaust, plus the machine has a filter on its inlet. Please stop the knee-jerk reactions. CPAP devices and aerosolized droplets are a problem if you know the patient is infected and you are up close to them putting the masks on.
