US 9,005,347 B2 · Air purifier

Abstract

An air purifier includes a frame, a fan unit, and an electrostatic precipitator. The precipitator has a first strip with a first continuous conductive electrode layer directly adjacent to an edge, and a second strip with a second continuous conductive electrode layer directly adjacent to an edge. The first and second strips are nested with one another. The edge of the first strip is opposed to the edge of the second strip. An electrostatic precipitator for an air purifier includes a first spiral strip having a continuous conductive electrode, a second spiral strip having a continuous conductive electrode and nested with the first strip, a plurality of combs. Each comb extends from an outer periphery of the precipitator to an intermediate region between the outer periphery and a center of the precipitator.
