Abstract
A wearable face covering may include a mask including a filter and a cap, wherein the cap is configured to prevent any gas passing through the filter in a first direction from exiting the mask in the first direction; and a face shield including a partially-transparent screen, wherein the face shield is pivotally coupled to the mask.
Claims19
A wearable face covering, comprising:
- a mask, wherein the mask includes:
- a base with a first central opening, the base including an interior side at least partially enclosing an interior volume, and an exterior side;
- an adapter including a flange and a coupling surface, the flange and the coupling surface surrounding a second central opening, wherein the flange abuts the interior side of the base, and the coupling surface extends through the first central opening of the base, wherein the coupling surface includes at least one first slot in fluid communication with the second central opening, wherein the at least one first slot has a portion that is substantially perpendicular to a central longitudinal axis of the second central opening, wherein the coupling surface also includes an interior recessed area;
- and
- a filter removably disposed in the interior recessed area of the adapter;
- a face shield including a partially-transparent screen;
- a coupler including a flange, a venting surface surrounding a third central opening, and at least one second slot on the venting surface, wherein the second flange removably abuts the exterior side of the base, wherein the face shield is connected to the coupler and also configured to pivot relative to the coupler;
- and
- a cap removably engageable with the adapter, wherein the cap is configured to prevent any gas passing through the filter in a first direction from exiting the mask in the first direction.

- and
- a cap removably engageable with the adapter, wherein the cap is configured to prevent any gas passing through the filter in a first direction from exiting the mask in the first direction, wherein the cap includes a center portion that is received by the third central opening of the coupler, wherein the center portion includes one or more openings, wherein:
- any gas travelling from the interior volume of the base through the first central opening, must pass through the second central opening, the third central opening, at least one first slot, at least one second slot, and the one or more openings of the cap, before exiting the mask;
- and
- an entirety of the face shield is configured to be secured to a user without any direct attachment to a head of the user.
