A device for filtering air for a user comprising a frame formed in a generally oval-shaped band, the band encircling the user's head, with an upper portion extending above and behind the user's ears and a lower portion extending below and in front of the user's ears. The device includes components mounted to the frame, comprising an air intake filter mounted on the frame and communicating on one side with ambient air outside the device and on the other side with an inlet duct and an air outlet filter mounted on the frame and communicating on one side with air inside the device and on the other side with ambient air outside the device. The device also includes a battery-powered air mover mounted on the frame and operable to pull air through the air intake filter and through the inlet duct and push air out into the inside of the device and a rechargeable battery mounted on the frame to power the air mover. The device further includes a transparent face shield mounted on one side of the frame in such a way as to create an airtight seal between the face shield and the one side of the frame, a fabric component made from an air impermeable fabric and mounted on the other side of the frame in such a way as to create an airtight seal between the fabric component and the other side of the frame, and to encircle the user's neck, a head harness configured to rest on the user's head and support the frame with its components mounted thereon, and wherein the components are mounted on the upper portion the frame and on the lower portion of the frame so as to achieve a weight distribution ratio between the upper portion of the frame with components mounted thereon and the lower portion of the frame with components mounted thereon, the ratio being between 1 to 1.5 and 1.5 to 1.

Method and apparatus for personal isolation and/or protection are disclosed. In one variation, the system may include a passive filtration component having a mask configured for positioning over a mouth and/or nose of a user, wherein the mask has at least one portion configured to filter air passing through the at least one portion. An active filtration component having a fan may be included, wherein the active filtration component is configured to filter air entering or exiting the active filtration component via the fan, and a hose fluidly coupled between the passive filtration component and the active filtration component such that the active filtration component is remote from a face of the user when in use.

An air supply mechanism with lower air duct, a headgear and an electric protective equipment are disclosed. The air supply mechanism with lower air duct includes: an air inlet mask, the front of the air inlet mask being raised in an arc shape and the back of the air inlet mask being arranged to fit to the human face, the air inlet mask including a first ventilation structure and a second ventilation structure connecting the front and back; an air supply pipe fixed on one side of the air inlet mask and in communication with the first ventilation structure and the second ventilation structure to supply air to the front of the air inlet mask; and a filter screen fixedly covering the first ventilation structure to filter the air entering the first ventilation structure from the front of the air inlet mask.

A method alerts a user that a volume of air being circulated through a powered air purifying respirator assembly is outside an acceptable range. The powered air purifying respirator assembly includes a fan and a hood system. The method begins with the step of measuring airflow through the powered air purifying respirator assembly to create a measured airflow value. The measured airflow value is compared to a predetermined high airflow value and a predetermined low airflow value. And, after a predetermined amount of time, an alarm signal is generated when the measured airflow value is either greater than or less than the predetermined high airflow value or the predetermined low airflow value, respectively. During the time when the incorrect airflow is occurring, the motor of the fan may be adjusted to correct the airflow values before the alarm signal is generated.
