FILTER FOR AIR CLEANER AND AIR CLEANER USING IT

摘要

PROBLEM TO BE SOLVED: To provide a filter for air cleaners is capable of capturing dust effectively and ensuring an air flow and allows a long-period use. SOLUTION: The first filter passage 22 having the first filter medium 20 and the second filter passage 23 having the second filter medium 21 are arranged in parallel. The second filter medium 21 is arranged obliquely with respect to the first filter medium 20 so that dust D captured by the second filter medium 21 is guided to the first filter medium 20 through an air flow toward the first filter medium 22. The second filter medium 21 has a conical shape, and the first medium 20 has a cylindrical shape so as to surround the periphery of the second filter medium 21. COPYRIGHT: (C)2008,JPO&INPIT
