What kind of face mask gives the best protection against Covid-19?

Does it matter what sort of mask you wear?


Yes. Different types of mask offer different levels of protection. Surgical grade N95 respirators offer the highest level of protection against Covid-19 infection, followed by surgical grade masks. However, these masks are costly, in limited supply, contribute to landfill waste and are uncomfortable to wear for long periods. So even countries that have required the public to wear face masks have generally suggested such masks should be reserved for health workers or those at particularly high risk.


The evidence on the protective value of single-use paper masks or reusable cloth coverings is less clear, but still suggests that face masks can contribute to reducing transmission of Covid-19. Analysis by the Royal Society said this included homemade cloth face masks.


Are paper surgical single-use masks better or is a cloth mask OK?

The evidence on any mask use, outside of surgical masks, is still emerging: there appears to be some benefit, but the exact parameters of which masks are the best and the extent to which they protect the wearer or those around them are still being figured out. A tighter fitting around the face is probably better, but the CDC suggests any covering, including a bandana, is better than none.
