I have a couple questions regarding passive intakes (just a 6" hole in the wall near the floor). #1. What is the bet way to make sure no light gets in or out of my room through the intake hole? #2. How do I prevent smell from escaping out the intake hole? Especially when/if the exhaust fan is not on? I'm sure the exhaust fan will always be on but im still concerned?
