A filtered ventilating system for a cooking unit incorporates a hood emplaceable above a cooking unit. An exhaust stack extends from the hood for removing cooking fumes captured by the hood. A barrier wall divides the interior of the hood into inlet and outlet zones open to the cooking unit and exhaust stack, respectively, and is provided with a fume opening to receive a filter for grease and the like. Wash down pipes respectively extend along the exhaust zone of the hood adjacent the filter and along an exhaust stack. A motor rotates the wash down pipes and a suitable supply provides wash liquid to the pipes, which are thus energizable to simultaneously rotate and spray the wash liquid onto adjacent hood, filter and exhaust stack surfaces for cleaning same. Pivot and latch apparatus supports the filter for reversal on the barrier wall, to permit both sides of the filter to be cleaned by liquid from the wash down pipes.
