  • Description:
    The National Personal Protective Technology Laboratory (NPPTL) is conducting a series of respirator assessments in response to the COVID-19 pandemic, see Figure 1. These assessments include determining the filtration efficiency of non-NIOSH approved respirators and NIOSH-approved respirators from stockpiles that are beyond their designated shelf life. NIOSH will also begin sampling respirators and determining the fit and filtration efficiency following decontamination procedures. The assessment in this test plan applies only to the filtration efficiency of expired NIOSH-approved N95 respirators.

    This protocol establishes a method for assessing the particulate filter efficiency of N95 respirators that are stored in stockpiles and are beyond their designated shelf life. This assessment was developed as a means to quantify the filtration efficiency of a NIOSH-approved respirator that is beyond its manufacturer-supplied shelf life date or has been subjected to prolonged storage in a stockpile. This effort supports increasing the availability of respiratory protection to US healthcare workers due to the respirator shortage associated with COVID-19.
