A growing body of evidence supports the idea that wearing face masks in public, even when you feel well, can help curb the spread of coronavirus. Face masks can also offer the wearer some protection, though how much varies depending on the type of mask. So how do you choose the right face mask for you?
The three factors that you should consider when choosing a face mask are the fabric, fit and breathability. How well a mask protects is a function of both what it’s made of and how well it seals to your face. But if you can’t breathe through it, then you’re less likely to keep it on. Below are some tips on how to choose a face mask that’s both effective and comfortable.
The Centers for Disease Control and Prevention says that people should wear cloth face coverings in public. Researchers from the National Institute of Standards and Technology say a tight-weave 100% cotton is best. That’s because at the microscopic level, the natural fibers in cotton tend to have more three-dimensional structure than synthetic fibers which are smoother. The 3D structure can create more roadblocks that stop incoming particles. A good way to check the tightness of the weave is to hold the mask up to a light. If you can see the outline of individual fibers, it’s not going to make a great filter. Wearing a mask made of synthetic fibers is not as good as a cotton mask, but it is better than no mask at all.
In order for masks to be effective they must seal well to your face. Cloth masks with pleats or folds are a good choice because the folds expand so that you have more air flowing through the fabric itself instead of leaving out through gaps at the sides of the mask.
A neck-gaiter, or buff, is designed to cover your face, nose and mouth and wrap around you. Although they are typically made of synthetic materials there is less of a chance of the air to escape laterally out of the sides like it would a mask that’s open on the sides.
N95 respirators are designed to create a tight seal around the nose and mouth, and when worn correctly, they can block at least 95% of small airborne particles. N95s remain in short supply, and you should know that there are counterfeit respirators out there. The CDC has some tips on how to spot counterfeit respirators on their website for more information.
Surgical masks are disposable masks that are worn loosely around the face. They are more effective at blocking large particle droplets or splashes in the air, but not very small particles. Many surgical masks sold in the U.S. have not been cleared for medical use by the FDA. Another reason why surgical masks may not be the best choice has been the increase in ocean pollution created by the coronavirus pandemic.
As we all continue to do our part to keep our communities safe, why not add a little touch of personality to your face mask. Incorporate unique prints, patterns and colors in your masks to add some fun to a serious matter.
Remember that no mask will offer full protection. It is also necessary to keep good habits up including social distancing and frequent hand washing.
Stay safe!
