ABSTRACT:
An air purifier is provided having a purifier housing and an air way housing mounted therein. A fan having a cylindrical whirlpool leaf construction is mounted within the air way housing and air is directed in a predetermined direction through an air exit opening formed in a wall of the purifier housing. An extended and tapered discharging copper needle is electrically coupled to a high voltage generator contained within the purifier housing and produces negative ions. The discharging needle is pointed in contour and has an apex end located adjacent the air exit opening. The discharging needle extends in the direction of the passage of high pressure air from the purifier housing which allows the discharging needle to vibrate responsive to the high pressure air flow and increases the amount of negative ions mixed with the air passing from the purifier housing.
