What this video covers
The clip is about where the unit sits rather than what it is set to.
A dehumidifier needs air moving freely on all sides to work at its rated capacity. Pushed against a wall or into a corner, intake and exhaust are restricted and it processes far less air than the specification suggests.
The takeaway
Position affects output as much as capacity does. Central placement with clearance around the unit gets more out of the machine you already own.
