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 .
