PROBLEM TO BE SOLVED: To selectively use an optimum filter apparatus since many kinds of conventional filter apparatuses for kitchen range hoods are provided corresponding to various range hoods. SOLUTION: In a filter apparatus for range hood formed by mounting a filter material on an attaching frame in a freely detachable manner, the attaching frame has trough-shaped connection plates 2 each formed by integrally forming a guide plate 2b and a slide groove part 2c in both longitudinal side edge parts of a long flat plate material 2a mutually opposedly and corner plates 3 each formed by erecting and fixing a side plate 3b along the outer edge part of an L-shaped flat plate material 3a. The side plate 3b is brought into slide contact with the guide plate 2b of the connection plate 2 to fit an L-shaped flat material inside edge part 3c in a slide groove part 2c in a freely slidable manner to connect the corner plate 3 to the connection plate. Four corner plates 3 arranged in a square shape are connected by four connection plates 2 to form a square frame and the corner plates 3 are slid in a connected state so as to be freely extended and contracted before and behind as well as left and right to arbitrarily change a frame dimensional shape. |
