I think labs have something crazy like 6 full air changed an hour which means they need to essentially pump in 6 or more rooms full of air every single hour and this massive CFM (cubic feet per minute) load generates a large pressure difference in the room so it’s impossible for the unpressurized hallway to contaminate. pretty cool imo

We do the reverse for asbestos abatement. Negative pressure so no fibers escape.
