A modular respiratory protection system comprising:
- a frame defining an opening configured to expose a portion of a user's head;
- a face shield moveably coupled to the frame;
- a coupling configured to rotatably couple the face shield to the frame, the coupling including a detainer and an intermediate member, wherein the intermediate member is coupled to the face shield and is moveable relative to the detainer, and wherein at least a portion of the detainer is fixed relative to the frame and at least a portion of the detainer is configured to resiliently deflect as the intermediate member moves relative to the detainer;
- an air filter;
- a blower configured to draw air through the air filter and through a portion of the frame and deliver the air between the face shield and the user's head;
- and
- a head protection element releasably coupled to the frame, the head protection element configured to cover the opening.

A modular respiratory protection system comprising:
- a rigid frame defining an opening configured to expose a portion of a user's head;
- a face shield moveably coupled to the frame;
- an air filter configured to wrap around a portion of the user's head;
- a blower configured to draw air through the air filter and through a portion of the frame, wherein the blower is configured to be above a user's ears when the frame is on the user's head;
- a head protection element releasably coupled to the frame, the head protection element configured to cover the opening;
- and
- a battery coupled to the frame, the battery being configured to supply power to the blower and the battery being configured to be decoupled from the frame while the frame is on the user's head.
