I going for aesthetics I might just put them in the ceiling and have what appears to be low profile vents that one might not even notice. That would keep most of the noise in the ceiling. One could build an enclosure that the HEPA filter unit sits in and routes the intake/output to different ceiling vents. With a little extra effort the filter could be swapped out by removing/lowering the vent intake.
