Union Health Minister Harsh Vardhan has said that N95 masks with respirator valves in them do not prevent the coronavirus from spreading out. He said, N95 mask fitted with perforated respirator is contrary to the rules adopted to prevent the spread of coronavirus. In a tweet, Dr Vardhan appealed to everyone to use a triple layer mask made of cloth and also to encourage others for this.
Director-General of Health Services, Dr Rajiv Garg has written to the Principal Secretaries of health and medical education of all the States in this regard. In the letter, Dr Garg said that the use of valved respirator N95 masks is detrimental to the measures adopted for preventing the spread of coronavirus as it does not prevent the virus from escaping out of the mask.
