The weather in Jinan is heavily polluted or lightly polluted almost every day. I want to buy a mask. What model is suitable?

It is recommended to choose masks above N95 level. For example, 3M 82 10, 8577 and 3M 3200 dust-proof and anti-virus combination, if necessary, you can go to Lantian Labor Protection Network to check the performance and description of the mask; Whether the dust mask really plays a protective role, in addition to choosing the protective function, another important selection factor is suitability. There is no one-size-fits-all design that can suit everyone's face. At present, the certification test of dust mask cannot guarantee that the mask is suitable for every specific user. If there is a leak, pollutants in the air will enter the breathing area from the leak. The way to choose a suitable mask is to use a fit test. It uses people's sense of taste to produce bitter or sweet particles with special tools. If you can still feel the smell after wearing the mask, it means that the mask is leaking. See the introduction of physical fitness test in GB/T 18664 for details. If necessary, you can enter the blue sky labor insurance search picture introduction and description. I hope it helps you!
