This study looked at ways to improve mask fit to reduce exposure to SARS-CoV-2. The recommendation for double masking is based off the findings of a CDC study. How much more effective is double masking? working a job where you cannot maintain physical distancing.traveling with others outside your household, such as by plane, train, or public transportation.However, a double mask can be beneficial when you’re: If you can maintain a distance of at least 6 feet from others outside your household, a single mask can give good protection.
Make sure that your double mask doesn’t block your vision. While breathing may require a little extra effort when you’re double masking, it shouldn’t make breathing difficult. To do this, cup your hands over your mask and feel for air escaping from the edges as you breathe. Make sure that the outer mask helps press the inner mask close to your face, forming a seal. Try out your double mask at home before using it in public. As such, avoid combinations of the following: Some mask combinations may not improve fit or may make it hard to breathe. The CDC recommends layering a cloth mask over a surgical mask. Now that we’ve discussed double masking and its potential benefits, you may be wondering how you can wear two masks safely and effectively. This is because it effectively doubles the layers of material that virus-containing respiratory droplets have to travel through before reaching your face and mouth. In fact, the Centers for Disease Control and Prevention (CDC) recommends using a face mask with at least two or three layers of fabric.Īdding a second mask can improve filtration even more. The layers of a mask help to increase its filtration power. The material in a mask filters respiratory droplets containing the virus before you can inhale them. SARS-CoV-2 is mainly spread through respiratory droplets that are made when someone who’s contracted the virus:

When this happens, the inner mask fits more closely against your skin and creates a better seal. When you’re wearing two masks, the outer mask can apply gentle pressure to the edges of the inner mask. Double masking can help to better prevent this from happening. This imperfect seal can not only allow respiratory droplets containing the virus to escape your mask, but it can also allow them in. In fact, you’ve probably noticed that you feel air escaping through the sides of your mask when you breathe in and out. Many types of masks don’t fit perfectly on your face. Double masking is when you layer one mask on top of another.
