An air cleaning apparatus draws air through a convoluted air channel defined by a plurality of non-permeable baffles. The baffles are arranged so that the air stream must change direction several times before exiting the apparatus. A fluid curtain is disposed along at least a part of the convoluted channel to remove particulate material from the air stream. One preferred embodiments causes fluid to flow over the baffles to provide a plurality of fluid curtains arranged along the air channel.
