The rear wall of the bag includes means to attach the bag to the user and the peripheral seal is interrupted at one or more places along the top edge of the bag. Filtering material such as carbon cloth or a housing containing filtering material can be welded in place between the front and rear walls of the bag at the opening in the peripheral seal. In one preferred embodiment, the filter element comprises a mounting block sealed into the top peripheral edge and a cartridge containing filtering material which is inserted in the mounting block.
