A filtration method for removing particulates from the air. In an electrostatic precipitator, the air stream is passed through a series of positive charge plates. Further downstream is a negatively charged collector plate that attracts and holds the particles. The high voltage of the plates causes the formation of ozone, and thus should not be used in museums.
