Double-masking or wearing a cloth mask on top of a medical-grade mask helps filter more particles than wearing a single cloth mask alone, says health director-general Dr Noor Hisham Abdullah.
Sharing information in an infographics on his Twitter account, he said a US Centers for Disease Control and Prevention study had concluded that double-masking can substantially reduce the wearer’s exposure to Covid-19.
“Although it’s not mandatory together with the face shield, it gives maximum protection,” Noor Hisham said.
According to another infographic he shared, an unknotted surgical mask blocks 56.1% of particles, a cloth mask 51.4%, a knotted and tucked surgical mask 77%, and double-masking 85.4%.
Always pair a surgical and a cloth mask for double-masking, and avoid wearing a similar type of mask for the purpose, according to the infographic.
Another infographic shows that no doubling up is required for the N95 mask as it is the gold standard and can seal the face and filters 95% of particles.
