So I have a wall mounted AC unit in Thailand with a compressor outside. The air is definitely not coming from inside as the only vents on the wall unit are exhaust cold air coming in to the room.
I gather I can’t put a HEPA filter on the inside, but how about strapping one to the outdoor compressor like in your home made DIY flat fan version? It wouldn’t be totally flush so would it still have any effect? Or just break the machine?
