DemeTECH's Surgical Face mask is FDA cleared, manufactured using the highest quality of American made materials, and 100% manufactured in The United States. The DemeTECH Surgical Mask is rated ASTM Level 3, this mask provides the highest level of protection. Made of three layers, two non-woven, and a white melt is blown filter inside. The inner 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 layer. This is not a chemical residue and does not affect the quality, functionality, or safety of the mask.
- Protective Layer: The outer layer ensures proper wear and provides high protection against fluids, high breathability, and excellent protection against airborne bacteria.
- Filter Layer: Provides at least 98% filtration against airborne particles and bacteria.
- Inner Comfort Layer: Enables wearers to comfortably wear masks for extended periods of time.
