Zusammenfassung:	PURPOSE: To prevent lowering of a purifying effect by a small amount of unprocessed air by a method wherein after unprocessed air is fed to a low pressure chamber through an internal leakage spot located in the bypass circuit of an absorption filter holding part, the air is fed to an absorption filter again. CONSTITUTION: In a selectively bypassing filter mechanism arranged in the passage-form housing of a heating/air conditioning device, unprocessed and leakage air is collected through an absorption filter holder 19 and an internal leakage spot located in the cut off bypass circuit 8 of an absorption filter 3. The unprocessed air is introduced in a space 28 of a low pressure level formed between a housing partition wall 17 and a cap body 29 to cover a blower 2 through the leakage air passage 27 of the filter holder 19. Further, the unprocessed air is circulated and fed to the absorption filter part 3 along with unprocessed air sucked through an external leakage spot located in a housing partition wall 17 along with operation of the blower 2.
