The Exhaust System

A ducted exhaust system, also known as a vented system, employs ducts to transport air away from the house. "Out" is the essential word here. It means you won't be able to vent into another part of your house, such as the attic. If you have a ducted system, it's ideal to mount your kitchen hood on an external wall. The ducting will be shorter and more efficient if you position it this way. The ductwork and installation will get more involved and expensive as you travel further away from an exterior wall.

Rather than being directed outside, the air is filtered, cleaned, and returned to the kitchen using a duct-free exhaust system or a non-vented system's mechanism. This duct system is less efficient and requires additional care, such as cleaning and filter replacement on a regular basis. Know what to expect from the start.
