Each time a wearer dons a respirator, they must perform a seal check to be sure that they have an airtight seal to the face so that air does not leak around the edges of the respirator. (PAPR respirators may not require this because they don't necessarily seal to the face.) This check is different than the periodic fit test that is performed using testing equipment. Filtering facepiece respirators are typically checked by cupping the hands over the facepiece while exhaling (positive pressure check) or inhaling (negative pressure check) and observing any air leakage around the facepiece. Elastomeric respirators are checked in a similar manner, except the wearer blocks the airways through the inlet  valves (negative pressure check) or exhalation valves (positive pressure check) while observing the flexing of the respirator or air leakage. Manufacturers have different methods for performing seal checks and wearers should consult the specific instructions for the model of respirator they are wearing. Some models of respirators or filter cartridges have special buttons or other mechanisms built into them to facilitate seal checks.<ref>{{cite web |title=Filtering out Confusion: Frequently Asked Questions about Respiratory Protection, User Seal Check (2018) |url=https://www.cdc.gov/niosh/docs/2018-130/pdfs/2018-130.pdf |website=NIOSH |access-date=8 December 2021}}</ref><ref>{{harvnb|ANSI Z88.2|2015}}</ref>
