摘要：
A face mask for filtering air includes a face seal for providing an airtight flexible seal around the nose and mouth of a user, a support sealably attached to the face seal, wherein the support has an open area that allows for passage of incoming air and outlet valves for expelling exhaled air, a front shell for removably attaching to the support, wherein the front shell has inlet holes for allowing the incoming air to pass through the open area of the support, and a filter for filtering particulate elements from air. The filter is configured to be housed between the front shell and the support. The face seal provides a direct connection between the filter and the user.
