This set contains both grease and charcoal filters, designed to be cut to size. It is recommended that filters are changed regularly to avoid excessive build-ups that can adversely affect the performance of the cooker hood.

With the black stripes facing in, cut your new grease filter to size. 3. Cut your charcoal filter to size and place it on the inside of the grease filter. 4. Put the cooker hood grid back into place.
