Abstract
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.
