Dust Masks
A dust mask is respiratory protective gear to prevent inhalation of particulate matter such as dust, fumes and mist. The product is worn in cases when dusty work is performed such as, welding work, grinder work, etc. You must use a mask that has passed the national qualification, and you need to choose one that suits your working environment. Dust masks are distinctive in that they are divided into two types: disposable dust masks with integrated filter media and replaceable dust masks that use replacement filters. Symbols such as L for liquid particles and S for solid particles are assigned to each, so that the types of particles that can be prevented are known. Some disposable masks have an exhaust valve for easy breathing, and some replaceable masks not only deal with dust but also counter odors.
