CDA hoods offer two modes for air extraction: Ducted Mode and Recirculation Mode.

• Ducted Mode vents air outside through ducting, providing stronger extraction, better air quality, and less filter maintenance. It's ideal for kitchens with external venting options but requires installation of ductwork.
• Recirculation Mode filters and purifies air before returning it to the kitchen, making it perfect for homes where venting outside isn’t possible. It’s easier to install but requires regular filter maintenance.
