For PM2.5, What Medical Mask Can Effectively Protect?

I heard that the N95 mask is the most effective. Is it reliable? "In recent years, the persistent PM2.5 haze weather has caused great inconvenience to the lives of the general public, affecting the health of the body, and many citizens report problems When it comes to physical discomforts such as chest tightness and coughing, the number of masks that can prevent PM2.5 and life protection has also continued to increase.

The smog weather led to the hot sale of N95 masks. In the smog weather, various masks began to sell hotly, and the number of newly sold masks continued to increase. Cotton masks, disposable masks, gauze masks, and even N95, all kinds of styles are eye-catching, and some businesses have issued PM2.5 masks as hot words for promotion, the price is from about 20 yuan to 30 yuan All of them.

The masks on the market are basically disposable medical masks, gauze masks, cotton masks, etc. Recently, the sales have been good. What style of masks are available. In fact, in a pharmacy, the clerk also recommended a mask called PM2.5, which has four spare filter elements. You can put the filter element in the inner layer of the mask when using it. After using it for a period of time, you can replace the new filter element. "A chip can be used for up to a week, and it should be replaced in a week." Pharmacy staff said.

For the new product PM2.5 mask, there is no relevant effect evaluation. The N95 masks that are popular on the Internet can achieve 95% of the filtering effect after testing, and the protection of PM2.5 should be effective. But for N95 masks, similarly, the higher the standard of protection, the greater the relative respiratory resistance. If you have asthma or difficulty breathing, it is not recommended to wear N95 masks.
