An auxiliary unit for a face mask with earloops comprises a rectangular or oval main body, the main body includes first and opposite second end. At least one first hanger and more than one second hangers are arranged on the main body, the first hanger being close to the first end while the second hangers are closer to the second end. The wearer hangs one of loops of the mask on the first hanger and selects one second hanger for securing the other loop, depending on his head circumstances, therefore, the auxiliary unit releases ears from pressures of anchoring the face mask loops and improves experiences of wearing the face mask.

A personal exhaled air removal (PEAR) system for removing/evacuating exhaled air from a vicinity of a patient is designed to remove the exhaled air during an exhalation cycle of a patient. The system is synchronized with a patient's breathing cycle for activating suction of exhaled air via at least one suction inlet, and the suction inlet is adjacent to the patient, possibly attached to the patient via an interface.

Provided is a mask apparatus. The mask apparatus includes a mask body in which a microphone and a speaker are installed, a face guard coupled to a rear surface of the rear body so as to be in close contact with a user's face and having a breathing space therein, a pressure sensor installed in the mask body to measure a pressure of the breathing space, and a controller configured to compare a current pressure value measured by the pressure sensor to a reference pressure value and control a voice output of the speaker based on a difference between the current pressure value and the reference pressure value.

A mask apparatus includes a mask body that defines a suction hole and a discharge hole, a face guard detachably coupled to the mask body by magnetic force and configured to contact a face of a user, and an air cleaning module configured to filter external air and to supply the filtered air to a breathing space. The face guard includes a coupling portion facing a rear surface of the mask body. The coupling portion includes a magnetic body and a magnetic body mounting portion that receives the magnetic body. The magnetic body mounting portion includes a mounting portion body that protrudes forward from an outer surface of the coupling portion and an insertion guide rib disposed inside the mounting portion body, where the mounting portion body and the insertion guide rib are spaced apart from each other to thereby define an insertion hole that receives the magnetic body.

The containment of aerosols produced in dental processes and treatments is of notorious relevance since they represent a high risk of transmission of infectious diseases, such as viral flu or COVID-19. Medical personnel in the dental area, or others, are exposed to a high risk of infection by constant exposure to these aerosols and splashes. Consequently, it is providing a protective shield for odontological procedures that functions as a physical barrier avoiding contact of dentists, orthodontists and/or their technicians/assistants with aerosols and splashes that occur during dental treatments and procedures.

A protective face mask has a first panel, a second panel and a plurality of head attachment features. The first panel is configured to cover the facial area of a wearer below the eyes with a mouth opening for the mouth region of the wearer to allow the wearer to eat, drink or smoke. The second panel is configured to cover the mouth opening when not used for passing food, drink or smoking. The plurality of head attachment features are located at outer edges of the face mask panels.

An illustrated view of an exemplary improved mask for preventing eye-glasses from fogging up is presented. The mask is useful for preventing air to flow from the mask onto the eyeglasses of the wearer of the mask. Also, the mask is useful preventing the spread of infectious diseases such as COVID. The mask provides for limited touching of the mask. The mask further is light-weight, comfortable and cost efficient.

A modular mask including a first module including a frame having two or more openings, and an attaching mechanism lining one or more edges of the two or more openings; and a second module including: a mask body having a first attaching element allowing the attaching mechanism to temporarily hold the mask body in place completely covering a first opening of the two or more openings, and a filter component having a second attaching element allowing the attaching mechanism to temporarily hold the filter component in place completely covering a second opening of the two or more openings.
