Claim:
A grease filter, comprising: upper and lower baffle assemblies which, in a closed position, define tortuous paths for exhaust air flowing therethrough; a hinge connecting said upper and lower baffle assemblies thereby permitting said assemblies to pivot relative to one another from said closed position to an open position enabling ready access to all surfaces of said assemblies for purposes of cleaning said assemblies; and a locking mechanism for securing said assemblies in said closed position, said locking mechanism being located on a peripheral side of said assemblies opposite said hinge; each of said baffle assemblies including an array of spaced-apart baffles, and each of said baffles having an elongated base wall with opposite sidewalls extending transversely therefrom to define a channel; said sidewalls of said baffles in said lower baffle assembly have a plurality of apertures; and in said closed position, said baffles in said upper baffle assembly being staggered relative to said baffles in said lower baffle assembly to define said tortuous paths.
