Abstract

One variation of a respirator apparatus includes a shield center section, a filter assembly, and a gasket. The shield center section defines: a transparent center region configured to align with a nose and a mouth of a user; and a filter window laterally offset from the transparent center region. The filter assembly includes a filter media and a seal: encircling a perimeter of the filter media; and defining a center groove configured to mate with a rim of the filter window to transiently retain the filter assembly within the filter window. The gasket is arranged on a rear face of the lens center section and configured to: seal against a face of the user; and locate the lens center section and the filter assembly offset from the face of the user to form an airflow channel to direct airflow across a glabrous cheek region of the user.
