How to choose a dust mask?


       Speaking of dust masks, it is actually a kind of personal protective equipment. Ordinary disposable masks must not only effectively block the intrusion of fine particles, but also ensure unobstructed breathing. It is best to choose single-core and double-core disposable nose wires. Masks can better fit the bridge of the nose and face. The filtration efficiency of disposable masks is sufficient for dust prevention. Secondly, the airtightness is good, but the airtightness cannot be too high. For example, the airtightness of KN95 masks is too high, and it will feel breathless when worn on hot days. , Its comfort is very poor.

      For industrial dust prevention (such as painting, polishing, etc.), the spray and dust are toxic to the human body, and there should not be a little inhalation of the respiratory tract. In this industry, disposable masks are completely insufficient, and professional anti-haze masks are required.

      This reminds the general public to treat the relevant instructions on the product packaging rationally when choosing dust masks, choose masks with high filtration efficiency and good air permeability, and do not wear masks for a long time to avoid hypoxia damage to the lungs.
