Abstract
A grease filter () for domestic extractor hoods comprises at least two walls () placed face to face and having first through openings () made in them arranged in such a way as to cause sudden changes of direction in the fumes flowing through them. At least one of the walls () includes a plurality of second openings () whose flow section is considerably narrower than that of the first openings (). The first openings () and the second openings () combine to divide the total flow passing through the filter () into two component flows which are in turn divided into a first plurality of macroscopic flows () following a labyrinth path through the first openings () and a second plurality of microscopic flows () passing through the second openings ().
