I am setting up my room and wanting to keep the smell to a minimum. I have a charcoal filter and inline fan for exhaust. Due to heat issues, I also setup a portable air conditioner, which also requires its own separate exhaust. Now from what I understand the filter should take care of the smell, but I'm just wondering: am I going to have a problem where the air conditioner might suck in some unfiltered smelly air and blow it out? I never thought about this until now, and now I'm feeling pretty dumb... Does anyone have any experience with this?
