Abstract: According to one aspect of the invention a device for purification of air is provided, including a metal plate electrical connections connected to the metal plate in order to impress a voltage on the metal plate, a heating element for heating the metal plate, and a nozzle connected to a water supply in order to spray the metal plate with water. In further embodiments the device includes a metallic cylinder, a fan disposed at one end of the cylinder and a restriction disposed at the other end of the cylinder, together with live coils for providing an electric field, where the centre of the electric field around the coils coincides with the location of the device's other units.

Abstract: The device according to the invention includes a drip chamber, which is adapted for connecting to the ordinary water mains, a metal plate and a nozzle that is connected to the drip chamber and disposed above the metal plate and a collecting vessel. The object of the drip chamber is to convert the continuous flow of water from the water mains into discrete drops, thus forming a water reservoir in the bottom of the drip chamber, which is electrically insulated from the water supply while the reservoir still receives a constant new supply of water. Water from the reservoir is passed on to the nozzle and sprayed over the steel plate. An impressed voltage on the nozzle and thereby the water attracts the impurities in the air and these will bind to the water and follow it when the water runs down into a collecting vessel, which is subsequently emptied into the house's drainage system.
