i remember watching a video of several guys "hot-boxing" (smoking weed in the car) a model x. they then turned on bio-weapon defense mode and you could watch the smoke getting sucked away and a few minutes later the new-car smell was back.
Non-Bio will do the same thing with the fan turned to 11. This is about evacuating the car with outside air, not the idea that the incoming air came through the HEPA.
