COVID-19 Protective Gear Masks
Particulate Respirator Mask Industrial N95 Cup Elastic Strap One Size Fits Most White NonSterile
Features
- This classic disposable N95 particulate respirator is designed to help provide comfortable, reliable worker respiratory protection against certain non-oil based particles
- NIOSH approved for at least 95 percent filtration efficiency against certain non-oil based particles
- Two-strap design with welded dual point attachment helps provide a secure seal
- Cushioning nose foam
- Lightweight construction promotes greater worker acceptance and may help increase wear time

Definitions
Filter performance – the filter is evaluated to measure the reduction in concentrations of specific aerosols in air that passes
through the filter.
Test agent – the aerosol that is generated during the filter performance test.
Total inward leakage (TIL) – the amount of a specific aerosol that enters the tested respirator facepiece via both filter
penetration and faceseal leakage, while a wearer performs a series of exercises in a test chamber.
Inward leakage (IL)– the amount of a specific aerosol that enters the tested respirator facepiece, while a wearer performs a
normal breathing for 3 minutes in a test chamber. The test aerosol size (count median diameter) is about 0.5 micro meter.
Pressure drop – the resistance air is subjected to as it moves through a medium, such as a respirator filter.
