1. The outbreak of the new coronavirus has affected the lives of many people. People are unable to travel because of this disease. Therefore, some manufacturers will also suffer heavy losses because of it. However, in order to prevent this virus, the mask factory has been working overtime to produce. There are many types of masks on the market now. So when we choose a mask. How should I choose?

2. The first thing is to look at the source of the mask. For example, does the manufacturer of masks have relevant qualification licenses and whether all its raw materials are safe?

3. The second is to look at the packaging of the mask. You should pay attention to whether the packaging of the mask is complete. Does the product meet the production standards and does it have some standard numbers?

4. The third thing is to look at the printing of the mask. For example, are the trademarks and fonts printed clearly on the packaging? And some genuine masks will also have anti-counterfeiting marks. These are also an important criterion for verifying authenticity.

5. The fourth step is to look at the logo. For example, whether the mask is within the shelf life. Are all his production dates and manufacturers correct?
