Made of three layers, two black non-woven, and a white melt is blown filter inside. The inner black layer is thinner than the outer layer so that it is more comfortable against the face. This results in some uneven coloring (mottling/streaking) where the white shows through the black layer. This is not a chemical residue and does not affect the quality, functionality, or safety of the mask.
The Black outer layer ensures proper wear and provides high protection against fluids, high breathability, and excellent protection against airborne bacteria. Provides at least 98% filtration against airborne particles and bacteria. Enables wearers to comfortably wear masks for extended periods of time.
