I came to say the same thing.

My lab uses an industrial laser cutter a lot, and perspex fumes stink. We have a large extraction unit to capture the fumes.

Filters only capture a limited range of compounds too. Important to always check whether the filter can handle the material before cutting.

Take a look at the specs -- you can either vent them out a window or buy the air filter (which I'm guessing is a fancy charcoal scrubber, don't know for sure).

I had missed point 12 (air filter upgrade), and non of the pictures showed an exhaust tube...
