A multi-unit grease filter includes a first filter unit and a second filter unit, each having an upstream series of spaced apart elongated baffles and a downstream series of spaced apart elongated baffles offset from the upstream series of baffles so that the baffles overlap and expose the air to multiple surfaces as it travels through the filter. The baffles have their ends connected to a pair of end frame members, each of which has at least one spacer in the form of a side edge having a first portion co-extensive with the upstream series of baffles and a second portion co-extensive with the downstream series of baffles so as to provide an off-set in each of the end frame members so that when the first and second filter units are disposed in abutment side by side, the off-sets align and overlap so that a bifurcated seam line is formed at the abutment and a downstream baffle overlaps with an upstream baffle at the seam line.
