Checks on Masks Sold in Singapore for Effectiveness against COVID-19

Mr Lim Biow Chuan asked the Minister for Health whether the Ministry conducts checks on face masks being sold in Singapore to assess their effectiveness in protecting against the COVID-19 virus.

As one of the measures to reduce the risk of spread of COVID-19, everyone is required to wear a mask when outside of their homes. There are two main types of masks: (a) medical masks (also known as surgical masks), and (b) non-medical masks made of cloth or other fabric.

Surgical masks are used in the healthcare settings and for medical procedures, where there is risk of splash or contact with potentially infectious persons or materials. Surgical masks are regulated as medical devices by the Health Sciences Authority (HSA). All importers of surgical masks are required to provide HSA with the details of the masks they are importing. HSA also monitors global safety reports on such masks and will take necessary actions to recall affected masks from the market if there are any safety concerns. Local surgical mask manufacturing facilities are also required to comply with internationally recognised standards.

For the general population in a low transmission setting, in line with recommendations by the World Health Organization and other authorities, non-medical masks are sufficient to provide a barrier against droplets. Non-medical masks are not regulated by HSA. For greater effectiveness, the public is advised to look out for masks with appropriate fit and specifications, such as having at least two layers of fabric and better filtration capabilities. These are often indicated on the packaging or product description of the masks being sold.
