Patent ID: 8282699

Claim:
A filter unit panel comprising a plurality of filter units that are joined together, wherein each of the plurality of filter units includes a filter medium and a frame body that supports the filter medium, the frame body being a resin member having an upper surface, a lower surface, an inner peripheral surface, and an outer peripheral surface, the upper surface being located upstream of the filter medium with respect to a flow of air passing through the filter medium and facing an upstream side of the air flow, the lower surface being located downstream of the filter medium with respect to the flow of the air passing through the filter medium and facing a downstream side of the air flow, and the inner peripheral surface supporting the filter medium, and the outer peripheral surfaces of the adjacent filter units are partially in contact with each other but at least a part of the upper surfaces and/or the lower surfaces of the adjacent filter units are spaced apart from each other, and a bonding resin enters a gap between the spaced upper surfaces and/or a gap between the spaced lower surfaces to bond the adjacent filter units to each other.
