Currently, there are five kinds of masks on the market. The most common one is an ordinary cotton mask, but it has no protective effect on PM2.5. There are also activated carbon masks, although filtration is also claimed, but mainly filter odors. In pharmacies, dust masks and medical masks are the most common. Although they have no good protective effect on fine particles, such masks have large respiratory resistance and can easily cause dizziness, nausea and other symptoms when worn for a long time. Although most of the masks are in the form of anti-fog and smog, the standard of implementation and the protection rate are not reflected. According to the survey data, most of the masks that are advertised as able to prevent haze are not as effective as anti-fog and haze effects.

Anti-haze masks are varied, in fact, many do not have anti-fog and haze effect, then how should we choose? First of all, to buy anti-fog masks can pay attention to whether there is GB2026-2006 on the packaging of the relevant subscription standards. The standard specifies the technical requirements, testing standards and identification of self-priming filter type particulate respirator. At the same time, it must be selected in appearance, because the protective effect of the mask is closely related to the fit of the mask and the face when worn. The better the mask fits the face, the less likely the air outside the mask is to enter the mask.

The original Mori Sky Mask is an anti-fog mask created by the world's top technical team. The active air supply system provides 6 times the amount of clean air, speeding up the air circulation, and allowing the nose to enjoy breathing. With medical-grade high-efficiency filters, 99.5% effectively filter PM2.5 to meet the needs of the public in all kinds of travel.

At the same time, we must remind everyone that people suffering from respiratory diseases and the elderly and the infirm need to be cautious when selecting masks, and use masks that are comfortable and breathe relatively smoothly.
