Patent abstract
The present invention relates to an electrostatic filter. Particularly but not exclusively the invention relates to an electrostatic filter for removing dust particles, for example an electrostatic filter for use in a vacuum cleaner, fan or air conditioner. The electrostatic filter includes a filter medium located between a first and a second electrode, each at a different voltage during use, such that a potential difference is formed across the filter medium, the first and second electrodes being substantially non-porous.
