I live in northern county and can vent my 3d printers exhaust to the outside. Friend of mine from CPH did the same with his resin printer.
And if you actively went it outside carpet and close proximity should ok ok'ish health wise. It's just effort and noise that a lot of people don't like to put in.

Yes I've always wondered why they love carpets so much. When I lived in such an apartment it was terrible. Always dirty and dusty. I'd much rather have a plastic, wooden or tile floor (the latter not ideal due to breakage though).
But you can ventilate, especially if you blow the air outside through an active blower.
And finally, makerspaces are a great way to do these things anyway. A community that can support and help you when you run into issues, friendly people around to borrow equiment and materials from, and they're usually pretty cheap if you don't get a fixed desks.

* Do not locate dedicated work/personal spaces in close proximity to the printers if odors are a concern
That rules out all small apartments, where there isn't a room that can be dedicated to the printer.
* 3D Printers and uncured, open resin vats should be stored and operated in a well ventilated area or with local exhaust
That rules out all apartments in northern countries (like here in Denmark) with lots of insulation
