I propose a test! It shouldn't be too hard, you could close the rear vents and turn the air on full blast, no recirc or AC, and turn on the sensing system. Then just open up to the microfilters and light up a cigarette (or whatever you like to smoke) and blow the smoke into the intake. You should probably take off the microfilters to avoid unecessary wear, but I don't know if that would be fair to the sensing system (maybe the microfilters are part of it, although I doubt it). Then you take a deep breath or two. See if anything changes. You could even see what kind of tolerance the system has (assuming it works).
I'll volunteer for this, although I won't have time to do it until later.
