With repeated outbreaks in many countries overseas, many scientists have called on the public to minimize gatherings and adopt stricter quarantine measures. As more and more people realize the importance of wearing masks and maintaining social distancing, homemade Christmas masks are also popular among overseas consumers.

Masks play a crucial role in preventing human-to-human transmission of the virus. Wearing masks can help reduce transmission and the chance of contracting the virus. When two people wear masks, the risk of COVID-19 transmission is reduced to 1.5%. This risk increases to 95 percent when neither person is wearing a mask.

Therefore, some people wear two masks at a time, but in fact, for normal conversations in daily life, one mask is ok, and wearing two masks at the same time cannot play a better protective role.

Because respirator protection effect basically see the sealing, as long as wear masks closely fit with their face, so can be sufficient to prevent the virus infection, on the contrary the second floor of the wearing of masks inner layer and the layer mask outer contact, weak airtight sex of the two layers of face mask is not good, in the process of contact, can cause new infections appear instead.
