Are you still randomly choosing masks? Take a look at this protection level!

In today's society, the issue of air quality is increasingly drawing people's attention. Whether it is the large amount of dust generated in industrial production, the dust raised on urban roads, or the tiny particles released during interior decoration, all pose potential threats to our respiratory health. As the first line of defense against these harmful particles, the choice of protection level for dust masks is of vital importance. In China, the protection levels of dust masks are classified based on their efficiency in filtering fine dust in the air. This standard provides a strong basis for us to scientifically choose masks.

China's respiratory protection standards classify the protection levels of dust masks into three grades: KN100, KN95 and KN90. Each of these grades has its own characteristics and is suitable for different environments and requirements. The KN100 grade is the "top configuration" among dust masks and represents the highest level of protection. It has a filtration efficiency of 99.97% for fine particles larger than 0.075 microns, and can be called the "king" of filtration effect. In industries with extremely high dust concentrations such as coal mines, metal smelting, and cement production, workers are exposed to environments filled with harmful particles for long periods of time. KN100 masks can provide them with nearly perfect protection, effectively preventing dust from entering the respiratory tract and preventing the occurrence of serious occupational diseases such as pneumoconiosis. It is like an unbreakable "guardian", always protecting the respiratory health of workers.

The filtration efficiency of KN95 masks is 95%, which is slightly lower than that of KN100 masks. However, they can still meet the basic protective needs in many situations. In some environments with moderate dust concentrations, such as in building decoration, wood processing, logistics and warehousing, etc., KN95 masks can filter out most of the dust and reduce the harm of harmful substances to the respiratory tract. It has the advantages of comfortable wearing and relatively affordable price, and has been favored by a large number of consumers. For those who do not need to work in high-concentration dust environments for long periods of time but still require certain protection, KN95 masks are a good choice.

The filtration efficiency of the KN90 mask is 90%, making it suitable for environments with low dust concentration. In daily life, when we walk on the streets or take public transportation, there may be some dust and pollutants in the air. At this time, wearing a KN90 mask can play a basic protective role. It is lightweight and easy to carry, not imposing too much burden on users. Just like a considerate "little companion", it provides health protection for our daily travel.

When choosing dust masks, we should not only focus on the price or appearance, but also pay more attention to their protection level. One should scientifically choose the appropriate grade of mask based on their working environment, activity scenarios and protection needs. At the same time, we should also pay attention to the correct way of wearing masks to ensure that they fit closely to the face and avoid air leakage. Only in this way can the protective effect of dust masks be truly brought into play and our respiratory health be enhanced. Let's use scientific knowledge and the right choices to create a healthier and fresher breathing environment for ourselves and our families.
