ABSTRACT:
A renewable, multi-layered filter apparatus (20) is disclosed. The filter apparatus (20) includes a housing (22) having a fluid inlet (24) for ingress of a contaminated fluid flow and a fluid outlet (26) for egress of a filtered fluid flow. A filter element (28) is supported intermediate of the fluid inlet (24) and the fluid outlet (26). The filter element (28) includes a nested, pleated filter media (30) having multiple filter media layers (30a,b,c) which are independently removable from the filter element (28) so as to enable renewal of the filter function by simply removing one of the filter layers (30a,b,c).
