Respirator mask for CBRN or other protection
A respirator mask wearable by a wearer for protecting the wearer against inhalation of noxious agents (e.g., chemical agents, biological agents, radiological agents, and/or other poisonous or otherwise harmful agents that can cause disease, injury or death), such as a CBRN mask, may be configured to enhance protection of the wearer (e.g., by providing ballistic protection in addition to protecting against noxious agent inhalation) while reducing a burden on the wearer, such as by reducing respiratory resistance, improving visibility, and/or facilitating use of the mask (e.g., connection or disconnection of a filter, conduit, or other air-providing device to or from a breathing interface of the mask).

18. The respirator mask of claim 17 , wherein the second speech transmitter is attachable to and detachable from the filter mount.
19. The respirator mask of claim 1 , wherein the filter mount includes a threaded connector for connecting the threaded filter and a threadless connector for connecting the threadless filter.
20. A respirator mask for protecting a wearer against inhalation of noxious agents, the respirator mask comprising:
a facepiece;
a visor connected to the facepiece; and
a filter mount for mounting a filter to the respirator mask, the filter mount allowing a plurality of different types of filters to be mounted to the filter mount,
wherein the filter mount comprises a plurality of connectors that are different from one another to connect respective ones of the different types of filters,
wherein the different types of filters include a threaded filter and a first one of the connectors is a threaded connector for connecting the threaded filter, and
wherein the different types of filters include a threadless filter and a second one of the connectors is a threadless connector for connecting the threadless filter.
21. The respirator mask of claim 20 , wherein the threadless filter is mountable to the filter mount by being pushed into the filter mount.
22. The respirator mask of claim 20 , wherein the threadless filter is mountable to the filter mount by turning the threadless filter by less than a complete rotation in the filter mount.
23. The respirator mask of claim 20 , wherein the different types of filters include (1) a standard NATO threaded filter and (2) a filter different from the standard NATO threaded filter.
24. The respirator mask of claim 20 , wherein the filter mount comprises a valve to regulate airflow within the respirator mask.
25. The respirator mask of claim 24 , wherein the valve is configured to remain open while the filter is connected to the filter mount.
26. The respirator mask of claim 25 , wherein the valve is configured to automatically close in response to the filter being disconnected from the filter mount.
27. The respirator mask of claim 24 , wherein the valve comprises a movable closure, and a biasing member tending to move the movable closure to close the valve.
28. The respirator mask of claim 20 , comprising a selector to selectively change the respirator mask between a negative-pressure mode and a positive-pressure mode.
29. The respirator mask of claim 20 , comprising a speech transmitter to transmit the wearer's speech, wherein the speech transmitter is attachable to and detachable from the filter mount.
30. A respirator mask for protecting a wearer against inhalation of noxious agents, the respirator mask comprising:
a facepiece;
a breathing interface connected to the facepiece for allowing the wearer to breathe clean air;
a visor connected to the facepiece, the visor comprising a lens, the lens being panoramic and comprising a rigid material providing ballistic protection; and
a filter mount configured to engage with a plurality of different types of filters and to allow a flow of gas between a mounted filter and the breathing interface in at least one direction, wherein, the different types of filters include a threaded filter screwable into the filter mount and a threadless filter mountable to the filter mount without being screwed into the filter mount, the filter mount including a threaded connector for connecting the threaded filter and a threadless connector for connecting the threadless filter.
