1. Most masks on the market do not have certification information. Such products without certification information may not be resistant to viruses without quality assurance.
2. The mask made of cotton can only keep warm and cannot filter viruses
3.Requires KN95-compliant masks to filter viruses
4.Children’s masks do not require a filter element. Use it alone. One piece can be used for more than 1 week.
