Abstract A filter for a ductless range hood includes a layer providing an impact barrier for removing coarse particles such as grease spatters from cooking discharges and resisting the heat of incoming discharges, for preserving filtering capacity and service life of downstream layers, a second layer providing absorption of grease remaining in the cooking discharge after passage through the first layer, a third layer for removing noxious gases such as oxides of nitrogen and carbon monoxide from the cooking discharges and for absorbing odors, and a fourth layer for removing fine particles such as smoke from the cooking discharges. Various combinations of layers are disclosed as well as various structural and framing configurations.
