No, I have the booth close to airtight and the fresh air is sucked in through the filters and exhausted through the fan. When I turn the fan on it depressurizes the booth and all the plastic is pulled in. This is the best set up I have had so far and it clears the booth of overspray quickly. Before I spray the top coat I will change out the wall plastic, filters and probably replace the fan. I have gotten my $15 worth out of that one!!! You can see my booth exhaust. I just add cardboard box extensions to get it out the door and away from the house.
