Depending on the environment in which the disposable dust mask is used, the disposable nuisance dust mask can provide a higher level of protection than an ordinary mask can provide. Problems That Needs To Pay Attention To ●Wearing a suitable mask depending on different environments. ●The outer layer of disposable nuisance dust mask often accumulates a lot of dust, bacteria and other dirt in the outside air, and the inner layer blocks the breath of bacteria, saliva, so the disposable nuisance dust mask can only be limited to one-time use, not repeated use.
