Is a portable hepa filter sufficient? I don't even know what to look for.
I can't smell anything after the filter—not even the 99% pure IPA which smells much worse than Siraya Tech Fast resin—so I don't bother venting outside when it's cold out; it vents into the unfinished basement side room.
I wear a respirator, thick rubber gloves, treat every surface as "hot," and UV cure all my paper towels and anything that resin touched.
My Ultimaker sits on the desk in my office and I mostly print on it at night. It doesn't get much use.
I'm way more up on the filtration side because I live in the land of bushfire smoke and 3D printers appear to be particulate problems too so I would try particulate filtering first because it's easy.
The box filters used in aircons and central heating work fine for this, but you probably need another fan to suck on them, not just the rangehood blowing.
Jeez, mate, there are better ways .. put in some lavender (or other scented prolifically growing dense foliage plant), divert some grey water (kitchen sink, bath, etc) to drain through that .. and vent through the bush.
It's like a self cleaning sweet scented air filter that traps particles and only gets better with time.
(And you can tell everyone it's advanced biotech).
