What are face masks?

Face masks such as cloth or fabric masks act as a simple barrier and work as “source control”.

“Source control” refers to preventing the wearer’s respiratory droplets from traveling into the air and onto other people when the person wearing the mask coughs, sneezes, talks, etc.

These are not suitable for use during medical and surgical procedures in healthcare facilities, where exposure and risk of transmission of infection are higher. These masks may be used by the general public and in community settings. Please refer to MOH’s guidance and FAQs on the use of masks.

Face masks are not regulated as medical devices under the Health Sciences Authority (HSA). Therefore, the quality and effectiveness of face masks are not regulated by HSA.

How to choose a face mask?

For greater effectiveness, choose face masks that have good filtration capability. Examples of such masks include those distributed by the People’s Association and Temasek Foundation.

When selecting a face mask, look for the following specifications:

• Masks with at least 2 to 3 layers of fabric. As a general guide, the material should not be see-through when held against the light.

• Layers should preferably be made with different fabrics, including:

• Water-repellant outer layer

• Middle filter layer to remove particulates – this can be disposable filter inserts

• Absorbent inner layer to absorb droplets from wearer’s mouth
