AbstractA self-contained, portable air purification device is designed to continuously cleanse airborne particulates which include infectious respiratory organisms such as tuberculosis bacilla. Contaminated air is drawn into the device about 360° from the breathing or working zone to capture the airborne infectious respiratory organisms. The airborne microbial particulates are extracted by a high efficiency particulate air filter capable of eliminating 99.97% of all airborne particles that are 0.3 microns in size or larger. The filter is permanently sealed within a filter cube that is disposable in its entirety for replacement purposes. The filter cube is releasably secured within the device to provide a leak-free air tight seal eliminating any potential air bypass. Clean filtered air is discharged at the bottom of the device in a 360° circumference to create a recirculating flow pattern that effectively eliminates airborne particulate while diluting the air within the room with clean filtered air on a continuous basis. The device is designed to operate at various capacity levels depending upon the size of the room to be treated. When adjusted to its mid range operating level, the device will provide the average size room with more than five times the air changes as recommended by the Center for Disease Control.
