<p>PURPOSE:To inexpensively constitute an air purifier by constituting a dust collecting filter of a conductive filter impregnated with conductive substance and connecting the same to the negative pole of a DC high voltage power supply. CONSTITUTION:As a dust collecting filter, a conductive filter 15 impregnated with conductive substance is formed. An earth electrode plate 16 is fixed to the conductive filter 15 and connected to the negative pole of a DC high voltage power supply 11. When a blower 10 is rotated, dust particles contained in room air are positively charged to be attracted and collected by the conductive filter 15. By this method, a metal net becomes unnecessary and an air purifier becomes inexpensive.</p> |
