The industry in our country is developing rapidly. Many industrial workers wear disposable dust masks when they work. However, how to choose disposable dust masks for industrial use? Today, the small masks of disposable masks are simple for the majority of users. Under the introduction, I hope to get a help to everyone.
1, safety performance. According to the difference between the type of filter particles and the filter grade, the disposable dust mask can be divided into two major standards: KN and KP, and the corresponding level is 90, 95, and 100. The dustproof mask with the highest degree of protection is KN100 disposable dust mask and KP100 disposable dust mask. The filtration efficiency of ultra-fine dust is up to 99.97%, which can meet the needs of most working conditions.
2, comfort. Generally, a mask made of a material close to the touch of the human skin is more comfortable. Currently, the most suitable mask on the market is a mask made of advanced medical silicone material. At the same time, the respiratory resistance of the filter must be low to improve the working efficiency of the mask. Avoid breathing difficulties during the wearer's use.
3, convenient and practical. In actual use, people don't have much time to take care of a mask, so be sure to choose a convenient mask that is easy to wear. At the same time, it should also be considered that the mask and the face fit closely to minimize the air from entering the respiratory tract without passing through the filter of the mask filter directly from the gap between the mask and the face.
4. Finally, it is necessary to consider the economy. Selecting a disposable dust mask with a long service life and good quality can not only achieve the effect of preventing dust, but also reduce the investment of comprehensive protection cost.
