One thing about enclosures - depending on build plate you can need the printer door open for better printing temperature so an enclosure may not provide as much protection as people think.
Also, there are tiny fine strands of filament plastic that get liberated and can float around with various solvents and other components in printer filaments.
I don’t know other suppliers but Voxel has carbon filters for the X1C (probably others) and sells the bento box unit that together do a pretty good job of reducing at least some VOCs. Some have done some basic testing and the results are very promising that these can help reduce contaminant levels.
I bought the HEPA/carbon filters for the X1C and also a bento box. Bento box needed one additional hole to pass wires but did that with a hot screwdriver.
