Each lid is provided with a plurality of downwardly extending parallel blades which coincide with and engage valleys of the corrugated filters to seal and support the filters within their respective compartments when the lids are closed. Removable common walls are provided on the assembly between adjacent compartments and the assembly is provided with a removable rear wall.
