I'm just finishing up on my paint booth. I'm using a plastic laundry container and a ceiling exhaust fan ducted to a window.
Is it really a big difference as to performance (more effective fume smell removal) if:
1. the fan is at the back of the booth or on top of the booth (like a range hood); it was mentioned in the exhaust fan manual that the fan is designed to be ceiling mounted.
2. I place a commercial aircon filter in front of the fan grille?

Thanks....
