Vacuum cleaner utilizing electrostatic filtration and electrostatic precipitator for use therein
First Claim
1. A vacuum cleaner for receiving and cleaning a dirty air stream to obtain clean air comprising:
- (a) a cyclone removably mounted in a housing of the vacuum cleaner and having an inlet for receiving a dirty air stream and an outlet for removal from the cyclone of a partially cleaned air stream; and
, (b) an electrostatic filter positioned in the outlet from the cyclone and removably mounted with the cyclone.

Abstract
An apparatus for filtering a dirty air stream in a vacuum cleaner to obtain a clean air stream includes subjecting the dirty air stream to a first cyclonic separation stage to obtain a partially cleaned air stream and subjecting the partially cleaned air stream to an electronic filtration stage and optionally a second cyclonic separation stage to obtain the clean air stream. The electronic filtration stage is optionally removable with a cyclonic cleaning stage from the vacuum cleaner. The electronic filtration stage is optionally an electrostatic precipitator which utilizes air flow through the vacuum cleaner to generate the voltage used by the electrostatic precipitator.
