[Should I keep the vent fan on the whole time I'm cooking?]

Many vent hoods circulate air, but not all push the air outside of the home. You can tell if yours is a circulate-only, a vent-type hood, or a convertible hood by close examination of it.

Models with vent openings near the top front that the air blows through could be a circulate-only type of hood or a convertible type hood.

Models that have duct work coming out the top or back are probably a vent-type hood. Close examination will reveal what type you have.

If your hood has the vents in the front and the metal ductwork, then it is convertible. Careful inspection of the control panel may show a switch or lever to change where the range vent hood directs the air.
