Kimtech N95 Pouch Respirator is NIOSH-approved, providing a minimum 95 percent filtration efficiency of 0.3 micron particles (though not oil-resistant). It is designed to help guard against the risks posed by airborne particles and contaminants. Pouch-style respirator offers the wearer a large breathing chamber to maximize comfort. It comes with two comfort-fit headbands and a bendable nosepiece to customize fit and ensure a consistent seal. This respirator is not for the healthcare market and not for healthcare personnel. It passes all relevant NIOSH testing protocols (NIOSH approval protocols do not include specific tests for respiratory diseases).
