Ok, I'm new to 3D Printing and all that goes along with it. I've been reading about some of the "hazzards" of printing inside a small room, and while I don't think there has been any "real" empirical studies on the matter, it has lead me to think about how to clean some of those particles up while printing.

Thoughts: (As they pertain to FFC Pro in a room that doesn't allow for external exhausting)

1) Would guess that it's better to recirculate within the enclosure, as apposed to drawling air through the machine and filtering on the way out? (to keep interior temperatures from dropping)
2) Would guess this filtration system should be located high in the enclosure or in the canopy? (I would think that the particulate would be carried up with heat)
3) Not sure what filtering material that would be needed, but I would guess that <.3 microns would be required?
