Material: The outer layer is typically made of a water-resistant material such as non-woven fabric or spunbond polypropylene, the middle layer is a filter layer made of meltblown fabric or other filtration material, and the inner layer is made of a soft, absorbent material like cotton or spunbond polypropylene.
Design: Disposable 3-layer face masks are designed to cover the nose and mouth and have ear loops or ties to keep the mask in place. Some masks may have a nose wire to provide a tighter fit around the nose.
Filtration: The middle layer of the mask is designed to filter out particles and droplets. The effectiveness of the mask’s filtration can vary depending on the quality of the materials used.
Usage: Disposable 3-layer face masks are intended for single-use and should be disposed of after each use. They should be worn in situations where physical distancing is difficult to maintain, such as in public settings or when caring for someone who is ill.
