Anything you can tell us? Â
One of my work areas is in sealed multi-room facilities. Â The HVAC is 5 or 6 decades old (at least in design). Â I haven't been in them but once for months. Â I am very interested in making sure the air I breathe is COVID-free.
I remember one study where they showed that the localized air purifiers in a hospital apparently blew COVID-laden air to another part of the room where it infected another patient. Â The outflow of the purifier was presumably safe, but the Bernoulli effect carried virus-laden air along with the outflow.
Where ever you have airflow, even of clean air, other air gets moved as a result. Â Maybe the best way to think of it is not output vents but exhaust vents.
