<p>PROBLEM TO BE SOLVED: To achieve the reduction of pressure loss, the improvement of deodorant performance, and excellent antibacterial mildewproof property by a method wherein in a member to be applied to an air filter for an automobile, which is prepared by enclosing an adsorbent between two pieces of base materials, one side base material is made into a dust removal sheet. SOLUTION: In a member wherein an adsorbent is enclosed between two pieces of base materials, one side base material is made into a dust removal sheet. For one side base material at that time, a collection efficiency of a 0.3μm particle measured by 5.3 cm/s in facial wind velocity according to JIS B 9908 is 20% or over. Further, an antibacterial mildewproof agent comprising a metallic salt being any one kind of silver salts of at least one kinds of compound to be selected from a benzimidazole compound and others, is contained in an organic compound containing at least either of a nitrogen-containing heterocycle or a sulfur atom. Furthermore, the antibacterial mildewproof agent is contained in the other base material. Then, both base materials are nonwoven fabrics, and one side base material is used on an upstream side. Thereby, antibacterialy and mildewproofing treatments together with deodorization and dust removal are executed.</p> |
