Whether you go for a cloth mask or a surgical mask, these simple tests can help to determine if your mask is actually providing protection or not. As per the U.S.S Centers for Disease Control and Prevention (CDC), one should always wear a mask with two or three layers and avoid the ones with exhalation valves or vent. Recently, they have updated their guidelines and have asserted that wearing two masks- cloth above surgical- can provide 95 per cent protection from the virus.
Wearing a mask is just one method to protect against the virus. Practising social distancing and following good hygiene etiquette are some other ways to stay safe.
