A nonwoven fabric made of a material with a lower melting point than these is sandwiched between a high-performance filter paper and a gas treatment filter material, so that it can be formed into a desired shape from above the surface of the high-performance filter paper. The nonwoven fabric is melted by ultrasonic cutting along its outer edge, and the high-performance filter paper and gas treatment filter material are welded and fixed at the outer edge to form a two-layer filter member. and a film formed with an adhesive layer larger than that of the two-layer filter member is provided on the lower surface of the gas treatment filter material of the two-layer filter member through the adhesive layer. further, an adhesive layer is provided on the lower surface of the film, and a release paper is adhered;
A small filter made by applying a sealant between the outer edge of the layered filter member and the adhesive layer on the film. 2. A nonwoven fabric made of a material with a lower melting point than these is sandwiched between the high-performance filter paper and the gas treatment filter material, and ultrasonic waves are applied from above the surface of the high-performance filter paper along its outer edge to form the desired shape. The nonwoven fabric is melted by melting, and the high-performance filter paper and the gas treatment filter material are welded and fixed at their outer edges to form a two-layer filter member, and an opening is formed. At the same time, a film larger than the two-layer filter member is brought into contact with the lower surface of the gas treatment filter material of the two-layer filter member, and a sealant is applied between the outer edge of the two-layer filter member and the film. In addition, a small filter is formed by providing an adhesive layer on the lower surface of the film and adhering a release paper. 3. A nonwoven fabric made of a material with a lower melting point than these is sandwiched between the high-performance filter paper and the gas treatment filter material, and ultrasonic waves are applied from above the surface of the high-performance filter paper along its outer edge to form the desired shape. The nonwoven fabric is melted by melting, and the high-performance filter paper and the gas treatment filter material are welded and fixed at their outer edges to form a two-layer filter member, and an opening is formed. At the same time, a release paper formed with a larger adhesive layer than the two-layer filter member is added to the second layer.
A small filter formed by adhering to the lower surface of a gas treatment filter material of a layered filter member via the adhesive layer, and applying a sealing material between the outer edge of the two-layer filter member and the adhesive layer on the release paper. 4. In the small filter according to claims 1 to 3, instead of the nonwoven fabric sandwiched between the high-performance filter paper and the gas treatment filter material, a laminate is provided on the inner surface of either the high-performance filter paper or the gas treatment filter material. A small filter made of non-woven fabric. 5. In the small filter according to claims 1 to 3, in place of the two-layer filter member, there is a structure between one sheet of high-performance filter paper and a plurality of sheets of gas treatment filter material, or between a plurality of sheets of high-performance filter paper and one sheet of filter material. A nonwoven fabric made of a material with a lower melting point than these is sandwiched between the gas treatment filter materials,
From the surface of the top layer high-performance filter paper, ultrasonic fusing processing is performed along the outer edge of the top-layer high-performance filter paper to obtain the desired shape, and each of the above-mentioned nonwoven fabrics is melted to form the high-performance filter paper and the gas treatment filter material. A small filter using a multilayer filter member formed by welding and fixing the outer edge of the filter. 6. In the small-sized filter according to claim 5, in place of the nonwoven fabric sandwiched between each high-performance filter paper and the gas treatment filter material, any one of the facing surfaces of each high-performance filter paper and the gas treatment filter material is used. A small filter using non-woven fabric laminated on the sides.
