SPARES2GO Cooker Hood Carbon Grease Filter Kit for Bosch Kitchen Extractor Fan Vent This filters service kit will enable you to hygienically maintain and monitor the performance of your kitchen extractor as well as keeping your living environment free from harmful odours and grease residue. When in full use, each grease filter will usually last half as long as the carbon odour filter - which is why there are 2 grease filters in each pack. Every grease filter is designed with saturation indicators to make it easier to spot when it is time to change the filter. Important note: Your cooker hood is only as good as your filter.
