HIGHLY DURABLE HARMFUL SUBSTANCE REMOVING ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a highly durable harmful substance removing element capable of removing a harmful substance such as a malodor, bacteria or the like by the photocatalytic capacity of an optically reactive semiconductor and the adsorbing capacity of an adsorbent and enhanced in the lasting properties of the effect of harmful substance removing capacity by together using an air permeable base material having predetermined pressure loss. SOLUTION: The highly durable harmful substance removing element is characterized by laminating the air permeable base material, of which the pressure loss (P) measured at a surface wind velocity of 5.3 cm/sec according to JIS B9908 is within a range of 0.5 Pa<=P<=40 Pa, to at least one aperture cross section of a corrugated structure containing at least an optically reactive semiconductor and the adsorbent. Antibacterial and antifungal processing or charging processing may be applied to the air-permeable base material.
