Recirculation vs Venting [Qidi Q1 Pro]

Looking at a qidi q1 pro, and was wondering if a recirculating system (hepa + activated carbon within enclosure) or venting system (all voc and particulates to outside) is better in regards to being *more* safe (ABS, ASA, etc). If the recirculating system is better, I'd like some recommendations, otherwise I'll just run an inline fan along with the exhaust fan and vent outside with a backdraft damper (enclosure voc + particulates -> exhaust fan -> duct -> inline fan -> outside). The inline fan will supply around 120fpm~ according to the space in the printer, so it should be good (only real worry is that its so strong that It screws up with consistent internal temperatures of the chamber).
