History
In the early 1920s, John W. Newcombe invented a device that separated dust and particulates from the air. He called his new invention the "Newcombe Separator". The Newcombe Separator has a cup-shaped part at its center that spins at high speed, creating centrifugal force. Air can be pulled through holes in the separator, while anything with weight is effectively thrown outward from the separator, trapping it in the bottom of the machine. This air-cleaning device led to changes in the method of collecting dust and contaminants from the home and workplace.
It was quickly discovered, however, that cleaning the air was only taking care of a small percentage of the problem of indoor air pollution; the larger percentage of dust and debris in a room "settles" onto surfaces and any movement through that room would stir the dust and contaminants back up and into the air. Further research proved that by removing the contaminants at their source, they could effectively stop the cycle of stirring dust and contaminants up into the air every time there was movement in the room.
By the late 1920s, Leslie H. Green joined forces with Newcombe to develop the "Newcombe Bagless". In 1929, Green formed a new corporation. They named it Rexair, meaning "King of the Air". While the nation was in the midst of the Great Depression, the Rexair Company began producing, refining and marketing the Rexair Cleaner.
