ELECTRIC UNIT CLEANS AIR OF HARMFUL PARTICLES (Jun, 1935)

“Air Cleaners.” Is that what the kids are calling them nowadays?

ELECTRIC UNIT CLEANS AIR OF HARMFUL PARTICLES
Experimental models of an electrical unit to remove dust, soot, pollen and other solid and liquid particles from the air are being tested by Westinghouse Electric and Manufacturing company. Data are being gathered by physicians who are using similar units in treatment of patients afflicted with various types of asthma or pollen fevers. The unit is arranged to draw particle-filled air past two small wires, suspended horizontally. Connected to a power pack, which raises their voltage, these wires “charge” all air particles in their vicinity. This is called “ionizing” the air. Next, the ionized particles are drawn through a series of plates which also are charged. The plates have opposite polarity, with the result that the air particles move and cling to the plate, just as a needle jumps over to a magnet. Thus, air is made to clean itself. In addition, a film of oil covers each plate to make certain the particles stick to the plates. The air, freed of particles, then is sent into the room by a fan. The unit requires no more current than an ordinary electric lamp.

    I didn’t realize this was invented so long ago.

    The Sharper Image Ionic Breeze from a long time ago!
