Air Handler
It maintains odor levels in a normal familiar range, so if you open the windows and the air gets too fresh, it filters it through some dirty laundry samples to compensate.

Black Hat is demonstrating some form of air-conditioning unit that covers a wide-variety of air qualities, as opposed to a heater that just warms air, a filter that just removes dust or a dehumidifier with the main purpose of removing moisture from the air.

If such a unit contains both heating and refrigeration elements to it, it would be neither practical nor desirable to have a single temperature reference, below which the heating is triggered and above which the cooling is activated, as the sharp transition between the two could trigger a rapid switch backwards and forward between the two modes after any gross difference has been ameliorated and the instantaneous amount of difference from the ideal is much smaller (in either direction) than the change that a burst of alternating effects can propagate into the room. Instead, a lower limit and an upper limit can prompt each respective correction, with a range of degrees between which is deemed acceptable, though the measurement may drift a bit as doors are opened, people enter the room or just that convection finally sends volumes of previously severely heated or cooled air past the sensor. The engineering choices involved in making a usable device may be pre-set or left user-configurable. The same principle can be applied to humidifier/dehumidifier functions, to create a comfortable condition not too dry nor damp for comfort, etc.

It is not particularly usual to directly monitor the number of bees in an air-stream (usually, insect-screens are the main way to filter out any pesky creatures that might find themselves likely to be caught up in that way), and one might imagine that the upper limit should be zero, for use indoors in standard living/working spaces, but it might be technically feasible to accurately count bees (with or without distinguishing from wasps and other flying insects) and be able to allow some. But, unlike temperature or humidity, it would be rare (outside of a location used for agriculture) to have a non-zero minimum desirable quantity of bees. Even more so to then be directly equipped to upwardly correct the current value. For any minimum value that is not zero, this machine would be equipped to deal with it by, presumably, releasing bees (it seems to have at least one trapped inside it ready to be released, judging by the buzzing sound), or by generating smoke, dust and odors – something one would typically not miss if lacking.

As the title text elaborates, the machine analyses and adjusts the 'freshness' of the air. A smart system in charge of odor-control (by spraying smell-suppressing chemicals and/or more desirable and dominant scents) could be made less wasteful by only trying to 'freshen' the air when it detects enough necessity. But, of course, this machine also has an opposing limit. And, when the air is considered too fresh, it has a way of adding staleness/stinkiness, to meet expectations.


[Black Hat is standing to the right of an "air handler", talking to Cueball and Megan on the left side, probably presenting the sales pitch for the air handler in between them.]
Black Hat: Our device monitors your home's air and keeps every variable between a lower and upper limit.
[Zoom in on Black Hat]
Black Hat: Temperature, humidity, pressure, dust, smoke, odors, number of bees...
[Zoom out similar to Frame #1]
Megan: Wait.
Megan: What's the lower limit for "number of bees"?
Black Hat: A normal amount.
Air Handler: Bzzzzzz

Don't be a jerk.

There are a lot of comics that don't have set-in-stone explanations; feel free to put multiple interpretations in the wiki page for each comic.
