Activated charcoal filter (pack of 1) design to suit Caple extractor TBU520 only. A Carbon filter is needed when your cooker hood is installed for air recirculation and not vented to the outside world. The air collected by your cooker hood is firstly passed through your grease filter (which removes the grease) and then through the carbon filter. This then cleverly helps to significantly reduce the amount of unpleasant odours released back into the room.
To ensure your cooker hood works to its best potential here at Caple we highly recommend that carbon filters are changed every 3 to 6 months depending upon usage
