Abstract
A face mask assembly includes a body shell having walls arranged in a three-dimensional configuration having an open back and interior area partially air impermeable. The front wall includes a vent portion permeable to airflow. An outer shell includes walls coupled in a polygonal configuration defining an open back and interior area that receives the body shell. The outer shell walls are permeable to an ambient airflow. A rain shield having moisture impermeable walls has a configuration complementary to that of the outer shell and is releasably coupled to a front surface of the outer shell, such as with embedded complementary magnets or eyelet openings. The facemask assembly includes an ultraviolet (“UV”) light assembly in the body interior area adjacent the vent portion, or in the interior of the rain shield and adjacent the vent portion, the UV light assembly producing electromagnetic energy capable of suppressing germs when actuated.
