Does my cooking hood have a carbon filter? How do I know if my hood has a carbon filter?

If your hood is connected to a vent, it doesn’t need a carbon filter. Hoods vented externally rather use a metallic grease filter. If you have a hood without a vent connection, it most likely uses a carbon filter. 

To find out for sure whether your hood uses a carbon filter or not, consult your user manual. If you’re having trouble finding your manual, download it here using your product’s model number.
