A personal respiratory protection device comprising a main body (12) carrying an exhalation valve (28), the valve (28) having a grip region (29) which is grippable in use by the user, the grip region (29) being configured to indicate to the user that the valve (28) is to be gripped during opening, donning and doffing of the device.

A respirator mask for long-term use is disclosed. In an example, a respirator mask includes a transparent lens integrated with a frame. The respirator mask also includes a first inhalation filter assembly connected to a left external side of the frame, a second inhalation filter assembly connected to an right external side of the frame, and an exhalation filter assembly connected to a bottom external side of the frame. Each of the filter assemblies have the same dimensions and include filter media, a base section configured o receive the filter media, a filter cap removably connected to the base section to retain the filter media against the base section, and a check valve located between the filter media and the base section or integrated with the base section. The disclosed respirator mask is configured to improve airflow and comfort for a wearer while minimizing postential causes of contamination.

A breathing equipment training device and a method for breathing training using a breathing equipment training device. The breathing equipment training device includes a shell and a diaphragm. The shell includes a first opening and a second opening, the first opening configured to be inserted into a breathing opening in a mask to form a connection with the breathing opening of the mask, and the second opening configured to be exposed to ambient air. The diaphragm is positioned in an inner cavity of the shell about the second opening, and configured to impede airflow into the shell through the second opening and to traverse along an axis between the first and second openings.

The disclosure relates to a respirator mask including a mask body and at least one filter for filtering a fluid (e.g. air) flowing through the mask and/or the mask body. The at least one filter may include one or more of: an Ultra-Violet (UV) filter and/or UV emitter, a filter fleece, and/or an electrical and/or electrostatic filter.

Air filtration masks are provided. In one exemplary embodiment, an air filtration mask includes a housing configured to be worn over at least a portion of a face of a user, an inhalation airflow channel formed within the housing and configured to receive an inhalation airflow, an exhalation airflow channel formed within the housing and downstream of the inhalation airflow channel, configured to receive an exhalation airflow that is different from the inhalation airflow, an inhalation filter structure in fluid communication with the inhalation airflow channel to allow the inhalation airflow to pass therethrough, the inhalation filter structure configured to yield a filtered inhalation airflow, and an exhalation filter structure in fluid communication with the exhalation airflow channel to allow the exhalation airflow to pass therethrough, the exhalation filter structure configured to yield a filtered exhalation airflow.
