#AskFedi #IAQ #CleanIndoorAir #HVAC folks:
My apartment's HVAC system, which is connected to an individual rooftop unit with its own fresh air intake ducts--is currently down. My understanding is that the issue is with the control module that is connected all the in-apartment on this floor, so all of our units are turned off.
I have a CR box air purifier, and a small portable one with miniature #HEPA filters, and an #Aranet4 air quality monitor.

Maintenance have installed a one-hose portable AC unit, with thermal tape around the edges of the open window. From the perspective of minimizing aerosol concentration, what is the best approach with respect to fan speed/mode options, i.e., always on, or only when cooling; blocking the undercut in the door, and opening a window in a different room?

I had also considered not using the portable AC at all; minimizing opening of the door and venting via windows with colder air at night.

OK, we've had computers in our houses for almost 50 years now.

When are they gonna make a computer with a pet hair filter on the intake fans?

Has anyone tried making a PAPR or HEPA stroller? A few people have mentioned the concept but the only source I've found is this one paper: https://www.researchsquare.com/article/rs-2430680/v1

I'd love practical tips. Right now I can't go into stores with my baby because she can't mask, having the ability to wheel her inside would greatly expand what I can do while caring for my child. Also useful during wildfire smoke.
