This mask has an adjustable nose bridge and is constructed with 3 layers: a velvet exterior layer, polypropylene layer, and dry-fit interior layer for better breathability.
(Polypropylene: an effective & eco-friendly fabric that works as a natural filter. This material traps incoming and outgoing droplets through a "cling effect" created by electrostatic charge.)
CDC recommends masks to be washed daily with soap or detergent and hot water. Make sure the mask is completely dry before you reuse it.
