1. What is the N95 disposable dust mask?   

N95 is one of the nine types of dust respirators certified by the National Institute of Occupational Safety and Health of the United States. N means that its material is only suitable for filtering non-oily particles. 95 means that its filtration efficiency is at least 95% under experimental conditions. . 

2. Is the smaller the dust, the harder it is to be filtered by the mask?     

no. The size of the most difficult to filter particles is generally 0.3 microns. Whether it is the European standard EN149, the American standard NIOSH, or the Australian AS1716 standard, 0.3 micron particles are used as the test medium for the mask. Only masks certified by an authoritative organization can effectively filter 0.3 micron particles and other particle size particles, and protect the human respiratory system from harm.
