A carbon filter does a superior job of cleaning the air before it re-enters the kitchen. This means you will have less leftover odours and the air will smell fresher.
A recirculating rangehood draws the air inside the appliance, cleans it and pushes it out through the chimney flue. Because there is no ducting required, these rangehoods are very easy to install.
Perfect for large spaces with high cabinetry or tall ceilings.
