1. A draping particulate filter for use in front of a user's nostrils and mouth comprising:
diaphanous PM filter material; a pair of protruding tabs, having affixation regions, associated with a portion of the diaphanous PM filter material, the pair of tabs being configured to be adhered to either side of the user's nose; a biocompatible skin contact adhesive located on at least a skin contact side of each of the tabs within the affixation regions; and multiple creases formed on the diaphanous PM filter material; the draping particulate filter having an outer peripheral shape bounding the diaphanous PM filter material such that, when the tabs are adhered to either side of the user's nose via the biocompatible skin contact adhesive within the affixation regions, the diaphanous PM filter material below the pair of tabs will hang freely in front of the user's face such that, upon inhalation by the user through their nostrils, a first portion of the freely hanging diaphanous PM filter material will be drawn towards the nostrils and act as a nasal filtration region and, upon inhalation by the user through their mouth, a second portion of the freely hanging diaphanous PM filter material will be drawn towards the mouth and act as a mouth filtration region, and upon exhalation by the user through their nose or mouth, the diaphanous PM filter material that is not adhered to either side of the user's nose via the tabs will move freely away from the user's nose or mouth, and wherein, based upon the creases, when hanging in front of the user's face, the peripheral shape will substantially lie in close proximity to a portion of the user's face. |
