Personally, if I lived in a high person density environment, I'd still consider direct venting to save some cash. If the neighbors complained about the noxious stench, I'd just claim it was the wife preparing dinner.🤠

Unfortunately our EPA (Environmental Protection Authority... another was to spell bloody WOKE) is not SWMBO cooking understanding... even death cap mushrooms.  I had a complaint that went to court and I was fined $5K (for a first offence) for turning on my mitre saw after 10:00pm... after complaints from a neighbour.
When I put up my decking between my "workshops" in the smoke, before moving to the country to downtown Churchill
the same neighbour complained to the EPA about my impact drill on a Sunday afternoon...  It cost me $2,000 to get the charge dismissed.  I wasn't prepared to risk my benevolent neighbour's sympathy for any venting outside... especially when the dusty might be operating for 1-2 hours continuous for a large laser job.
It's all this bloody Yankee litigations that have given some rsole Aussies subliminal open slather to whinge.  

If your first cut is too short... Take the second cut from the longer end... LBD
