In the video they explicitly said to place it “in front of the fan so the air blows through it”. I’m sure they’re aware of the back placement — avoiding the tape. Curious why they they did not recommend it in the back. Maybe negative pressure creates leaks? Damages the fan? The air filter frame was meant to bend in one way? Maybe the help filters are designed to handle positive pressure on one end and negative pressure causes the other end to expand and damage?
