The present technology relates to respirator devices including source control features. In some embodiments, a source control mask device can include a shield (706) that substantially covers the mouth and nose of a user and a mechanism (702) that can actively extract air as it is exhaled by the user. The extracted exhaled air can then be sanitized before the mask device discharges it into the atmosphere. The mask device may selectively form a seal (720) to the user's face dependent on air flow conditions.

The invention relates to a protective device such as a face mask. The device protects the user from infection and may simultaneously immunise the user against future infection. The invention particularly relates to a protective device comprising a disinfection chamber wherein the chamber is arranged to disinfect and/or sterilize fluid in the chamber prior to discharge of the fluid from the chamber such that the fluid discharged from the chamber comprises inactive microorganisms, for example a device comprising a disinfection chamber in fluid communication with a face mask and wherein the chamber is arranged to disinfect and/or sterilize fluid in the chamber prior to discharge of the fluid from the chamber to the mask such that the fluid discharged from the chamber to the mask comprises inactive microorganisms. The invention also relates to a method of use of the device.

A mask with grooved baffle is disclosed. The mask includes a cover, a strip and a baffle mounted at an inner side of the cover. The baffle separates the cover into two parts, an upper part and a lower part. The baffle is formed with a grooved section at the top, which includes a plurality of wave shape grooves for air flowing therethrough. The grooved section extends from one end of the baffle to the other end. When the user wears the mask, the baffle is positioned under the nose of the user, such that air flows smoothly to the nose through the grooves. The cover has a fixed structure or a foldable flat shape structure.
