How do I test My Can 66 Carbon Filter to make sure im not getting a odor?

is cigarette smoke able to be filtered through a carbon filter? or is that smell to over powering for the filter cause that seems like the cigarette smoke smell would be more over powering then the smell of my plants?

in my experience there is no smell more overpowering than flowering cannabis plants. You need to create a negative pressure in the room so that more air is going out than going in, Therefore all of the air must be filtered through the carbon before it is expelled from the room. Carbon filters work wonders, if its not working its not set up right.
