We disclose a window blind that includes a capacitor within each slat. Each plate of the capacitor may be connected to one of two batteries. At least one switch may be placed between each capacitor plate and its adjoining battery. When one switch is open, another switch may be closed thereby sending current to only one plate at a time. The plate that receives the current is negatively charged and the remaining plate is positively charged. The switch that is open may be changed to reverse the charges of the plates. This charge reversal may be actuated through a series of pull cord gestures from a user. By creating an electrical charge on the plates, dust is pulled from the air according to the net charge of the dust particles. The window blind therefore functions as an air purifier as well as a traditional window blind.

The present invention relates to an electrostatic precipitator (ESP) system (1) for removal of particles from a flue gas flowing in a flow passage (4) being delimited by a primary collection in the form of a collection plate (5). The system comprises a discharge electrode (11) arranged in the flow passage and connected to a high voltage generator (12) providing for an electric field around the discharge electrode. The system further has a secondary collection electrode in the form of a grid (101) arranged within the collection plate and made of an electrically conductive material. The presence of such a grid improves the efficiency of the precipitator. In some embodiments, the ESP system comprises an actuator (112) for moving the grid upwards and letting it drop onto an internal bottom structure (109). The movement between the collection plate and the grid as well as the impact force imparted to the dropping grid both result in a removal of collected particles.
