I think the answer to that should be it depends on what you are working with and want to extract. I mean, personally, I don't use any mechanical ventilation with any filters because I don't really need it. My CNC router and CNC lathe is in my home office / hobby room, where I also have a 3D printer and my electronic workshop, so the ventilation is the same as for the rest of my living are in my home. My metal "workshop" where I am cutting, drilling and working mostly with steel, aluminium and wood, does not have any mechanical ventilation because I don't need it.

Note that I am just a hobbyist, not a professional, and don't work with anything hazardous, like laser or plasma cutting, welding and so on, and in the 3D printer I only use PLA or PETG, and don't use my CNC for wood works.
