Hello, I purchased an air scrubber as the one shown here
The installation per se is rather easy, but complicated by the extremely compact size of the system in my apartment. The info in the pdf says to mount the air scrubber past the air handler.
My whole system is contained in a small space behind a hatch door on the ceiling, as shown in the first photo (green lines and arrows indicate airflow) and there is no space to insert the air scrubber in there.
I see two possible places for the scrubber. The first is to insert it vertically, on the side of the hatch door (position A). Possibly even inside the closet (position B), if there is some room before the duct bifurcates.
My concern would be if placing the scrubber so close to the AC coils would create problems due to the heat emitted by the UVC lamp that is in in the scrubber.
The other option is to insert the scrubber horizontally in the wall, past the return filter and before the air handler, somewhere along the path shown in the third photo.
The fourth photo is taken inside the return vent looking upwards and shows the vertical path of the air up from the return vent before turning right to go to the air handler. Behind the back wall there is a storage room where I can easily make a hole in the dywall and install the air scrubber in a more concealed way (it would protrude inside the air path in position C).
However, in this case the air scrubber would be placed before the air handler and not after, how it is recommended in the manual.
I would appreciate if anyone more knowledgeable than me could point out if this is a problem, and more in general recommend the best location to install the air scrubber.
Thank you very much for any suggestion or recommendation you are able to give me.
