ABSTRACT:
An air purification unit including a housing of substantially rectangular solid configuration and having an inlet and an outlet, a diagonal partition in the housing dividing it into substantially equal inlet and outlet chambers, first filters in communication with the inlet chamber for removing gases and particulate matter entering the inlet chamber, second filters in communication with the outlet chamber for removing submicron particles, and a specialized motorized impeller mounted on the diagonal partition for moving air from the inlet chamber to the outlet chamber, the motorized impeller including a stationary inlet ring secured to the partition, a stationary motor housing portion fixed relative to the partition and a rotatable motor housing portion carrying a backwardly rotatable impeller wheel for drawing air through the center of the impeller wheel as it rotates and forcing it radially outwardly through the impeller wheel to thereby pressurize air in the outlet chamber.
