Claims

[Claims for Utility Model Registration] 1. A pine-shaped nonwoven filter material is stretched in the same direction as the surface, and a cut portion formed by penetrating the nonwoven filter material in the thickness direction is expanded. air handling elements. 2. Claim 1, wherein the cut portions are formed in a staggered pattern.
Air handling elements as described. 3. The cut section consists of a cut section from one side edge of the non-woven filter medium to the nearest edge of the other side, and a cut section from the other side edge of the non-woven filter medium to the nearest edge of the one side, in a direction perpendicular to the stretching direction. 2. The air treatment element of claim 1, wherein the cuts are arranged alternately. 4 One flat plate-like plate material in which a corrugated non-woven filter sheet is laminated between two flat non-woven filter sheets is formed along a direction intersecting the direction of wave propagation of the corrugated non-woven filter sheet. It is characterized by being sequentially bent in opposite directions at the cut portion where the non-woven filter medium sheet and the corrugated non-woven fabric filter sheet are cut, and at the cut portion where the other flat non-woven fabric filter sheet and the corrugated non-woven fabric filter sheet are cut. air handling elements.
