摘要
A wearable mask includes a light module attached to a cover. The light module includes an inlet for receiving air to be breathed in by the person, and an outlet that faces the person. Airflow paths extend between the inlet and the outlet, and receive air to be breathed in by the person. An ultraviolet (UV-C) light source emits anti -microbial light into the one or more airflow paths at a wavelength that kills microorganisms in the air in the one or more airflow paths. Walls at the inlet and outlet each includes one or more slits through which the air passes. The one or more slits of each wall are offset relative to the one or more slits of an adjacent wall to form staggered airflow paths that allow the air to pass through offset slits, but blocks the anti -microbial light from passing through the offset slits.
