Guide on how to re-use face masks

A recent study indicated that the presence of SARS-CoV-2 virus persisted for 21 days on the surface of materials like PPEs, respirators and even plastic face shields or visors. On 100% cotton fabric, however, the virus went through rapid degradation and was undetectable within 24 hours. So, use a mask or face cover made of 100% cotton fabric with triple layers to ensure safety.

Wash the face cover after every use in soap and warm water. The CDC recommends washing the face cover in four tablespoons of household bleach mixed with a litre of water. The MoHFW also suggests boiling the mask in water mixed with salt to disinfect it.
