We disclose a window blind which purifies the surrounding air using electrostatic interactions. The window blind includes slats which may have a strip of positively charged material, a strip of negatively charged material, or both attached to the top of the slat. In some embodiments, the positively charged material and the negatively charged material are attached to alternating slats. In other embodiments, the positively charged material and the negatively charged material are attached to the top of the same slate with a strip of insulating material positioned between them. The window blind may include an air-moving device which moves air past the slats so that dust particles with either a net positive charge or net negative charge may be attracted to the oppositely charged material on the slat. The air-moving device may be a vacuum or a fan. The positively and negatively charged materials may be removeable for cleaning.
