How Effective is a Reusable Mask in Fighting the Coronavirus?Mark Watts
How good are reusable masks when it comes to protecting yourself against Covid-19?
While surgical masks are fluid-resistant and able to filter bacteria more effectively, reusable masks made of cloth or other material can still serve as a form of basic protection.
Reusable Masks for PPE
Reusable masks were distributed to households in Singapore, Spain and Italy after the Government announced that they will no longer discourage people who are well from wearing masks because there is evidence showing that people can be infected but not show any symptoms.
Dr Teo Tee Hui, council member of The Institution of Engineers Singapore (IES), who is also a senior lecturer at the Singapore University of Technology and Design, said reusable masks provide between 50 and 60 per cent of filtration efficiency. Therefore, it is highly advisable to wear these masks than to not wear any mask at all.
He added that to significantly reduce the risk of spreading the virus, it is important that the majority of the population wear masks.
