Is the range hood no longer extracting all of the cooking odors coming off your enthusiastic cooking activities? If so, it's time for a new Scanpart carbon filter. The filter measures 47x57cm, which makes it suitable for range hoods of up to 60cm. For a range hood between 90 and 100 centimeters in width, you can use 2 Scanpart carbon filters. To fully remove all odors, you should replace the carbon filter every 12 months.
