A facepiece comprising a main body having a geometry configured to fit on a human face and cover the human's mouth and nose is provided. The main body defines an interior cavity between the main body and the human's face. The facepiece also includes one or more straps extending from the main body and configured to extend around the ears or head of a human such that the main body is held on the human's face. The main body includes a filter defining a plurality of airflow torture paths extending therethrough between the interior cavity and an external environment. The filter includes three or more layers of airflow path defining features, each airflow path defining feature providing a passageway for air to pass therethrough. The path defining features in adjacent layers are fluidly coupled but offset to form the airflow torture paths.

A facemask adapted to be positioned on a user's face may include multiple components: a lower component or nose/mouth component; and an upper component or eye shield component. The eye shield component may be configured to at least partially cover the eyes of the user, while the nose/mouth component may be configured to cover the nose and mouth of the user. The eye shield component may be removably coupled to the nose/mouth component. The nose/mouth component may be configured to filter aerosols and droplets from the air/gas inhaled and exhaled by the user. The nose/mouth component may further facilitate the consumption of food and/or beverages without requiring the facemask to be removed or pulled down/away from the user's face.
