We believe that everyone is already aware of how to protect yourself from getting infected with COVID-19. The best way is to wash your hands every time you come in contact with spray , soap or alcohol gel included. Another thing that is indispensable. When it is necessary to leave the house is ‘ Hygienic Mask ‘. Of course, there are many types and types for us to choose from, whether it’s cloth masks, medical masks or N95 masks. In the past, many people may have heard that ” wearing a 2-layer mask “ can Helps to increase the effectiveness of preventing COVID-19 more than just wearing a single layer. But there are still people who question whether “Will it really help?” or “Should I wear two layers?” Today I have the knowledge and answers to answer all questions.

The CDC, or the US Centers for Disease Control and Prevention, ufabet thai has conducted a trial of wearing a two-layer mask to test how much protection it can provide. The experiment will test protection from coughing and breathing. The results from the experiment are as follows.

1. Prevention of infection from coughing

There are three types of cough protection tests:

• 1 layer cloth mask
• medical mask only 1 layer
• 1 layer of medical mask and cover with another layer of cloth mask

The results of the experiment revealed that Wearing a double-layer mask in Type 3 protects against 85.4% of infections from coughing, while wearing a single layer of cloth or medical masks can only protect against 51.4% and 56.1% of germs.

2. Preventing infection from breathing

For the results of this experiment, it was found that

• If the infected person wears a double mask (medical mask and cloth mask) while talking to an uninfected person who does not wear a mask. will be able to stop the spread of infection by more than 82.2%
• If the uninfected person wears a double mask (medical mask and cloth mask) while talking to an infected person who is not wearing a mask. It can prevent more than 83% of infection.
• If both the infected and the uninfected wear double-layer masks (medical masks and cloth masks), they can stop transmission by up to 96.4%.

Other advantages of wearing a double layer mask

1. Fitness

There are many types of masks that, once worn, cannot fit our face well. Therefore, when the infected person wears a mask, The virus can also spread. Because there is a gap between the face and the mask. At the same time, people who are not infected but wear masks are less fit. You can also get the virus. Which to solve this problem by wearing a 2-layer mask is a good option.

2. Virus filtration

Most infections are spread for three main reasons: talking, coughing and sneezing. Wearing a double layer mask will help filter out more of the virus for us. because when the virus escapes into the first layer But at least there is still a second layer that can still help filter us, so the CDC recommends that people wear at least 2-3 layers of masks ^( 2 ).
