Abstract: A ventilation system for removing cooking effluents and combustion products from an exhaust of a cooking appliance. The ventilation system includes a ventilation hood having an air inlet and an exhaust gas outlet disposed over the cooking appliance, a water bath disposed in the ventilation hood between the air inlet and the exhaust outlet, and an effluent removal assembly disposed above the water bath. The cooking effluents in contact with the effluent removal assembly are transferred to the surrounding water, and the clean airflow may be recirculated. Grease particles are also transferred to the surrounding water.

Abstract: A filter device and method of filtering components from a surgery plume. The filter device comprises an integral solution reservoir which intercepts an airstream passage and airstream and cooperates with the airstream to direct air and solution into pads to create a foam. The foam created by the pads and solution and additional elements of the filter react with one or more undesirable components of the surgery plume to cleanse the airstream prior to exhaustion into the atmosphere. No separate solution supply or delivery system is necessary.
