Air-King makes a SS range hood that is 24" deep by 36" wide, and comes in either an 18" high model (height of the hood canopy top to bottom), or a 10" high model. The 18" model number is P1836 and the 10" is P1036.

Most if not all of the GW discussion is about horizontal dimension (capture area) relative to the cooktop, and how high above the cooktop the hood is mounted. But what about the vertical dimension of the canopy itself? The baffle filters for both models are recessed into the canopy the same distance, so the extra space in the 18" model is between the filters and the duct - thus no added funneling effect that I can see. These two models are priced within $50 of each other so not much advantage either way there either.

Other than appearance, I can't think of any benefit to an 18" model over the 10" given identical horizontal dimensions, blower capacity, and duct size. But ... others are more experienced/knowledgeable than I, so wondering if there are any opinions.

Thanks for any thoughts.
