ASA and ABS really need a good filtration. Like actual filtration, not what the enclosure has. I personally just run a duct to my window and vent outside. | ||

That's largely a myth. This review [1] cites the absolute highest amount of emitted styrene in the studies they are reviewing to be 113 μg/min. Using [2] for simplicity with styrene's molar mass (104.15 g/mol), we get to a printer creating at most 0.024 ppm of styrene per minute per m3 of unchanged air. For comparison, the "work exposure limit (WEL) for styrene is currently 100 parts per million (ppm) averaged over an 8-hour day" [4]. In other words, as long as you have some air exchange in the room, you'd be orders of magnitude away from the safe work exposure limit on styrene. It also makes sense, considering that it's a microscopic amount of molten plastic, whereas injection moulding factories work with vats of the stuff.
