English
Fangdun9501 and 9502 are both KN95 grade disposable particulate matter protective masks, with a filtration efficiency of not less than 95% for non oily particulate matter. These two masks can be used in various work environments with particulate matter pollution, and wearers can choose with or without valves according to their actual working conditions and comfort needs.
Construction and Decoration Operations
Cement dust, gypsum dust, putty dust, and sand and gravel particles are often generated in construction, interior decoration, demolition and renovation environments. Both 9501 and 9502 are capable of filtering non oily particles in the air, making them suitable for workers to wear during mixing, cutting, polishing, cleaning, and other processes. When working indoors for a long time in high temperatures or with general ventilation, the valve type has lower exhalation resistance and a lighter sense of humidity and heat inside the hood.
Wood and Furniture Processing
Wood cutting, planing, sanding and other processes generate sawdust. Two types of masks can be used in woodworking workshops, furniture manufacturing, and other places. It is recommended to combine ventilation measures in environments with high concentrations of wood dust, and the frequency of mask replacement should be determined based on the degree of dirt and changes in respiratory resistance.
Textile, Grain, and Food Processing
Cotton dust and hemp dust in textile factories, grain dust in grain storage and flour processing, as well as powdered raw material dust in some food workshops, all belong to non oily particulate matter. Valve free models have certain advantages in these scenarios, as exhaled gas passes through the filter material, reducing the wearer's impact on the environment and the product. If the valve type is used for food processing, it is necessary to confirm whether the on-site hygiene regulations allow it.
Daily commuting and haze protection
Both types of masks can be used to reduce the inhalation of particulate matter in the air during dusty weather, hazy weather, or road construction areas. The daily commuting wearing time is relatively short, and the valve free version can meet basic protection requirements; When cycling or walking for a long time, the valve equipped version allows for smoother breathing.
Overall, Fangdun9501 and 9502 are suitable for workplaces with low environmental pollution. The valve free version is suitable for places that require bidirectional filtering, while the valve equipped version is suitable for high temperature, high humidity, or long-term heavy physical wear scenarios. When selecting, it is sufficient to consider the actual working environment, wearing duration, and on-site management requirements.
