A dust mask is a flexible pad held over the nose and mouth by elastic or rubber straps to protect against dust encountered during construction or cleaning activities, such as dust from drywall, brick, wood, fiberglass, silica (from ceramic or glass production), or sweeping. A dust mask can also be worn to protect against allergens. Nowadays, polymeric nanofibers are used for manufacturing such masks to improve their efficiency. They prevent inhaling the particulate matters with a diameter of 2.5 microns or less and heavy metals in the polluted air which causes many diseases including asthma or lung cancer.
This product is a dust mask containing polymeric nanofibers.
Nanofibers due to a large surface-to-volume ratio and high porosity increase the filtration efficiency. According to air cleaner test code 34, adding nanofiber to the filter improves its filtration efficiency.
