ABSTRACT:
A removable, washable air filter apparatus is formed with two V-shaped rectangular mesh filters held in place side by side within a housing with the vertices of the V filters draining grease and moisture into a removable pan. A mounting bracket maintains the pan in position to receive extracted grease and moisture without impeding air flow through the exposed filter mesh. The top edges of the housing have outwardly formed flanges for removably mounting the housing by means of overlying swivel retainers provided around the periphery of mating flanges on an intake opening of a ventilation hood or air duct.
