Abstract

Claims18
A respirator comprising:
- a body having a first side and a second side opposite the first side, the first side configured to engage a user's face,
- an internal airspace defined between the first side of the body and the second side of the body;
- an opening defined by the body;
- a door coupled to the second side of the body, the door movable between an open position and a closed position;
- a filter positioned between the door and the second side of body when the door is in the closed position, wherein the filter, the door, and the body cooperatively restrict air from transiting the opening without also transiting the filter;
- and
- an exhaust valve coupled to the body, the exhaust valve configured to allow air to exit the internal airspace in a first direction, wherein the exhaust valve is rotatably coupled to the body.

A respirator comprising:
- a body that is configured to define an internal airspace between the body and a user's face;
- a first opening defined by the body;
- a door coupled to the body, the door pivotally configured to actuate between an open position and a closed position, the door defining a second opening that is aligned with the first opening when the door is in the closed position, wherein a top portion of the door is pivotally coupled to the body such that the door pivots up towards a nose portion of the body when the door pivots from the open position to the closed position, the nose portion of the body configured to interface against a nose of the user's face;
- a filter detachably coupled to the door and the body such that the filter, the door and the body cooperatively restrict air from transiting the first opening without also transiting the filter;
- and
- an exhaust valve coupled to the body, air being permitted to flow through the exhaust valve in a first direction that exits the internal airspace;
- wherein the exhaust valve is rotatably coupled to the body.

- a door coupled to the body, the door pivotally configured to actuate between an open position and a closed position, wherein a top portion of the door is pivotally coupled to the body such that the door pivots up towards a nose portion of the body when the door pivots from the open position to the closed position, the nose portion of the body configured to interface against a nose of the user's face;
- a filter detachably coupled to the door and the body such that the filter, the door and the body cooperatively restrict air from transiting the first opening without also transiting the filter;
- an exhaust valve coupled to the body, air being permitted to flow through the exhaust valve in a first direction that exits the internal airspace;
- and
- an intake valve coupled to the door, air being permitted to flow through the intake valve in a second direction that enters the internal airspace;
- wherein the exhaust valve is rotatably coupled to the body.
