By that I mean literally sucking up stuff. The vent fan above my stove only seems to actually pull anything in while it’s on low; setting it to high makes it louder but stops pulling any smoke or steam up through the hood. I’m just curious how the hell that works; shouldn’t a faster spinning fan suck MORE? Is there some property of aerodynamics that was forgotten when they installed this shit?

      All of the entries here are incredibly insightful and great to learn from.

      But you don’t have an issue relating to aerodynamics, pressure differentials, air foils, or anything else like that.

      Either your exhaust is filthy, your filter is installed wrong, the outlet shutoff has been tuened, or there’s a blockage in the vent to the outside (bird nest).
