A device includes a chamber having an air inlet and an air outlet. The device includes a plurality of stages including at least a first stage adjacent a second stage. The plurality of stages are disposed in the chamber and each stage has a plurality of discharge electrodes disposed in an interior region and is bounded by an upstream baffle on an end proximate the air inlet and bounded by a downstream baffle on an end proximate the air outlet. Each stage has at least one sidewall between the upstream baffle and the downstream baffle. The sidewall is configured as a collection electrode and has a plurality of apertures disposed along a length between the upstream baffle and the downstream baffle. The upstream baffle of the first stage is positioned in staggered alignment relative to the upstream baffle of the second stage and the downstream baffle of the first stage are positioned in staggered alignment relative to the downstream baffle of the second stage.
