ABSTRACT:
A deodorizing air filter is capable of improving the strength and deodorizing ability while suppressing an increase of ventilation resistance and pressure loss. A filter body has a series of filter pieces which are formed into a zigzagged shape by folding along multiple folds of parallel lines of the filter element. The filter body is made of the deodorizing section and the filtering section formed alternatively, the filtering section of the air serves as a filter and deodorizer for the air, and the deodorizing section serves as a deodorizer for the air. As the deodorizing section does not serve as a filter, it is not necessary to make the pitch of each piece of the filtering section smaller. As a result, it is possible to suppress the increase of ventilation resistance and pressure loss.
