Most kitchens have an extractor hood above the hob, fitted or chimney style. They have filters that collect the grease whilst cooking. These filters need either replacing or cleaning depending on the type and frequency of how much cooking is done on the hob.
We carry replacement paper filters and we replace these types of filter as part of our clean.
Metal filters are cleaned in our dip tank in the rear of the van.
We do not carry replacement carbon filters but can arrange to order the correct one for your extractor for you.
