Replaceable dust mask 1015-02 type - Single type with RL2 filter material on the front. RL2 class mask with Unimicron filter. Skin-friendly and highly fitting silicone face piece adopted. The filter is a micron filter that collects dust by electrostatic force charged by special resin processing with wool felt as the base material. While maintaining the features of this micron filter, such as high collection efficiency and low intake resistance, advanced electrostatic processing is used to clear the RL class (DOP particles) of the national certification standard, which is considered difficult for electrostatic filters. It's an electrostatic filter. A special three-layer structure with two collection layers. Even with a thickness of about 1/3 that of conventional products, each collection layer achieves a collection performance that exceeds that of conventional hypermicron filters.
