The Director-General of Health Services, Ministry of Health, has warned against the "inappropriate use of N95 masks, especially those that contain respiratory valves" to help users breathe.

"The use of valved respirator N95 masks is detrimental to the measures adopted for preventing the spread of coronavirus as it doesn't prevent the virus from escaping out of the mask," the Director-General, Dr Rajiv Garg, wrote in a letter to states and union territories.

He further said that states and union territories should encourage the use of homemade cloth masks, which can be made by following guidelines issued by the Health Ministry.

The advisory comes amid rising concerns over the ineffectiveness of the valved masks to prevent the spread of the coronavirus.

“Respirators with exhalation valves should not be used in situations where a sterile field must be maintained because the exhalation valve allows unfiltered exhaled air to escape into the sterile field,” says the US CDC.
