There is a Scandinavian study specifically on this virus conducted in a controlled environment.
The virus managed to defy gravity and get into air vents above the patient.
It is in one of the videos here (sorry, don’t remember which video):

Am unfortunately not able to go through all those videos, but will watch a couple. Thanks!
And viruses don’t defy gravity - they have to adhere to the physical laws of nature just like any other organism. If it got into the vent, it got there by an explainable reason.
