Bye the way it is a "High efficiency particulate air (HEPA)" no not know what a HERA filter is.

Your problem is as simple as making a new top noise cover. You can make if the any material, I would go with smokey Plexiglas or Lexan sign face material.
Duplicating a facsimile of the original top thereby giving you area to enclose your air purifier.

1st. The case is not completely air tight if you flow the air inside thru a filter to exhaust clean air into the room. Choose filters carefully or your whole condo will smell.
2nd. As all the air will be enclosed in the case you merely recirculate the air thru an internal filtering system enclosed in the top sound hat.





Thanks. Could you please explain what "top noise cover" is? Any photo or drawing to illustrate what you suggested?
