A new type of filter assembly which can be employed to retrofit an existing shaker or which can be built as an integral part of a new shaker. The assembly is comprised of a series of compartments arranged in cascading fashion within the shaker. Each compartment is provided with a removable hookless corrugated filter having no additional support backing which secures between a perforated bottom of the compartment and a removable and reclosable lid. Each filter is sealed and supported from below, at its front and rear edges and along its sides within its respective compartment upon removable corrugated lips provided in each of the compartments. 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. Each of the common and rear walls is provided with port holes which coincide with valleys of the corrugations of the filters in order to allow tailings to pass between adjacent compartments and to exit the assembly.
