N95 masks The right mask for swine flu
Microbiologist Siddharth Dalvi said both the N95 mask and the disposable surgical one could be used “only one or two times”. However, he said the N95 mask was better equipped to block viruses as it had three layers of spun cloth. He said the mask was known as N95 as it “could block out 95 per cent of all particles”.

Dr Khushrav Bajan, ICU in-charge, Hinduja Hospital, said, “The N95 masks are the only masks that provide protection from the swine flu virus. The Rs 15 surgical masks are as bad as your handkerchief and should be changed every four hours.
Even then, there is no foolproof protection against the flu.”
