AIR PURIFYING RESPIRATOR HAVING INHALATION AND EXHALATION DUCTS TO REDUCE RATE OF PATHOGEN TRANSMISSION
摘要
<p>A filter mask includes an oronasal cup, an inhalation directional cover, and an exhalation diverter body. The oronasal cup encloses a nose and mouth of a user. The oronasal cup is fluidly coupled with a filter. The inhalation directional cover is configured to be joined to the filter. The inhalation directional cover includes an elongated wing portion that is oriented in an inhalation direction that is angled with respect to the center axis of the filter. The exhalation diverter body is fluidly coupled with the oronasal cup. The exhalation diverter body defines an exhalation duct that directs exhaled air out of the oronasal cup along an exhalation direction. The inhalation direction and the exhalation direction are oriented away from a plane of interaction between the user and another person.</p>
