VACUUM CLEANER WITH ELECTROSTATIC FILTER

摘要

A vacuum cleaner (10) comprising: a body (20) defining an air inlet (22), an air outlet (24), and a passageway (26) extending therebetween;an electrostatic dust filter (30) for removing dust from air as it passes through the passageway (26); and an air pump (40) for drawing air into the air inlet (22) and through the passageway (26) to the air outlet (24); wherein the electrostatic dust filter (30) comprises an electrode arrangement (32) configured to kill microorganisms present in air passing through the passageway (26) by exposing air to a voltage in excess of a threshold voltage.
