IMO I don’t feel the ionizer is the way to go. In my lab we have a blower set up directly above the printer. It is connected to a vent that goes straight up and out of our building. The blower is connected to a switch and during long prints, or when using IPA, etc. I just turn the blower on and up and out go the VOC’s, smells, etc.
Of course I work in a lab in an industrial warehouse, so much of this was easily accessible and easy to setup. Maybe in a small office/home/apartment you could set up a desktop blower, or even a fan towards a window? @cjones went all out.
