Abstract
Various reusable respirator designs are shown. In one example, a reusable respirator includes an inhalation pathway with a conduit extending from the exterior of the respirator into the nose piece allowing users to receive air directly into an inner sealed zone around a user's nose and mouth. The inhalation pathway includes a vent opening such that the inhalation pathway also directs air into a facemask zone, between the nose piece and an outer seal reducing/preventing shield fogging during inhalation. In another example, the respirator includes cartridge attachment lobes each having a different size and shape. A filter cartridge assembly can only be aligned with the lobes in one orientation, creating a robust connection. In another example, a storage bin for a reusable respirator includes a one-way film placed underneath a plurality of perforations allowing gases and moisture to escape the bin while limiting the ingress of other gases or particles.
