(54) Filter casing


(57) An air-conditioner filter casing which comprises first and second casing components (8, 9) each having a grid structure of at least one transverse bar (12) and a plurality of cross bars (13). To facilitate disposition of an air-purifying filter in the filter casing and also to minimize the flow resistance acting on the flow of air entering the air-conditioner (1), the first and second components (8, 9) are hingedly connected with each other so that the first casing component (8) can be selectively opened and closed relative to the second casing component (9) and in that the transverse and cross bars (12, 13) in the first casing component (8) are aligned in position with the transverse and cross bars (12, 1 3) in the second casing component (9), respectively.
