Should you double up on masks for extra protection? Plus how best to wear your mask

The Centers for Disease Control and Prevention (CDC) recently completed a study on the efficacy ratings for different kinds of masks. The data led the organization to recommend wearing a surgical mask under a cloth mask for optimal protection against the coronavirus. The CDC advises against layering two surgical masks for extra protection because it’s ineffective. 

A recent study found that using this combination of masks reduced transmission of aerosol particles by 95% compared to no mask at all. Although double masking is the gold standard, it’s also important to note that wearing any type of mask provides some protection. 

You can also use a mask fitter or brace to help prevent air from leaking out between your face and the mask. If you want extra protection, you can also knot the ear loops and make sure both masks fit snugly against the face. Watch how to correctly tie knots in the ear loops of your surgical mask.
