Scope: In some workplaces, workers may be exposed to low concentrations of chemicals such as organic vapors and acidic gases, although the concentrations of these chemicals in the workplace are lower than GBZ2.1-2019 "Occupational Exposure Limits for Hazardous Factors in the Workplace Part 1" : Chemical Hazardous Factors" (whichever is lower), and the hazardous factors do not reach the level specified in GB/T18664-2002 "Selection, Use and Maintenance of Respiratory Protective Equipment" for the use of respiratory protective equipment. However, due to individual differences, the odor may still cause physical discomfort to some workers. Disposable face masks (masks) are suitable for workers to protect against particles such as dust, smoke, fog, and microorganisms in the workplace. Adding an activated carbon filter layer to this product can effectively reduce odors such as organic vapor and acidic gases. This type of mask is widely used in the fields of production safety and occupational health.
