I don’t know if you was asking about my setup or lasermike ?
But this is what I have on the Bambu lab X1 in my office and for now has been working great with just the chamber fan and big carbon filter 
I have a few of these setups with fans before they made the 3d air filter systems you can also look into by
BOFA 3D PrintPRO 3 fume extraction system.
The inline filter is:
Solberg HE10™ HEPA Filter Cartridge 4"
