Coronavirus Prevention: Why N-95 Masks With Valves Do Not Serve The Purpose- Know Which Mask You Should Wear

N-95 masks with valves are not effective for curbing the spread of coronavirus. The Centre on Tuesday mentioned that N-95 masks with valves do not prevent the virus from spreading out and are detrimental to the measures adopted for its containment. In April, the government had issued an advisory on the use of homemade protective cover for face and mouth. Fabric masks that you make at home must be washed and cleaned every day. It is advised that people should wear the mask as much as they can, especially when they step out of their houses.
