The backdraft damper is one of those range hood components that most of us don’t ever spare a thought for.
And that’s ok.
Having said that, though, I’m going to spend a little time telling you about what a bonus a backdraft damper is.
The whole point of a range hood is to help maintain clean and healthy indoor air quality. It does that by drawing up cooking odors, smoke, grease, and potentially toxic fumes and exhausting all of them to the outdoors.
But, what stops outside air from making its way into your home? Usually, nothing. If you’re trying to make your home as energy efficient as possible, then you don’t want outside air leaking in.
That’s where the backdraft damper comes in.
The backdraft damper opens when you turn the range hood on allowing all that dirty air to escape to the outdoors. Once you turn the range hood off, the damper falls back into place blocking any outside air that might otherwise make its way into your home.
Not all range hoods come equipped with backdraft dampers. For instance, range hoods that are not ducted to the outside don’t need them. Actually, not all range hoods that are ducted have them. Sometimes, a backdraft damper isn’t really necessary, especially if the duct is located in a wind-protected side of the house.
