SINGAPORE: In the time of COVID-19, face masks have become part of everyone's daily routine.

But questions remain. Which face mask should you use? Which is better? When and where should you put them on? 

Like a good piece of personal protective equipment, we have got you covered.


If you leave your house, you should wear your mask at all times.

According to the Ministry of Health (MOH), this includes while you are on public transport, when you are walking, or when you are at work.

If you fail to do so, you can be fined S$300, with repeat offenders facing higher fines or prosecution in court.


According to MOH, any mask that "covers the nose and mouth" offers "adequate basic protection" in places where safe distancing and good personal hygiene can be observed.

This includes reusable face masks, DIY masks or plastic face shields - plastic spit guards predominantly covering the mouth are not considered masks.

Face masks should:

  • Closely cover the nose and mouth
  • Not leave a gap between the mask and face.

Face shields can be considered in situations where individuals may have difficulty wearing masks due to health conditions which include breathing difficulties, or where "impractical to use a face mask".

If you are a teacher, trainer or lecturer, you can also consider a face shield as long as safe distancing can be maintained.

However, if you have to interact with another person in close proximity, you should put on a face mask.


According to infectious disease experts, face shields provide limited protection and should be worn together with other masks in order to be effective.

Face shields are not meant to replace surgical masks or reusable cloth masks.

The open nature of the face shield protects users against “more forceful projections” but does not completely eliminate exposure or dissipation of droplets, says a professor.

4) WHAT IF I'M ...


If you are at work, you need to wear a mask  - it does not matter if you are a frontline staff member or someone who is performing back office functions.

Food handlers, including those who do not face customers, should wear a face mask.


If you are engaging in strenuous exercise outdoors, you may remove your mask. But you need to put your mask back on once you have completed your exercise.

Motorcyclists can remove their masks when riding, but should otherwise wear them at all times.

Anyone travelling in a car or van alone does not have to wear a mask. If the driver and passengers live in the same household, they do not have to use a mask when they are in the vehicle together.


You can remove your mask when eating, drinking or cleaning your face, but you have to put it back on immediately after.


Members of the public are reminded that they can only leave their homes for essential purposes, working in essential services or to buy food. 

Leaving the house just to smoke is not an essential activity.

If you are out for an essential purpose and wish to smoke, you may do so with the mask removed under the following conditions:

  • Being in an area where smoking is not prohibited under the smoking prohibition law
  • Observing safe distancing measures 
  • Not loitering after smoking

After smoking, the mask should be put back on immediately.

All Designated Smoking Areas within the Orchard Road No Smoking Zone (ORNSZ) as well as smoking corners located beyond the ORNSZ have been closed as part of measures brought in to prevent the spread of COVID-19.


Wearing a mask is not recommended for children below the age of two for safety reasons. Children who are older than two have to wear masks at all times like everybody else.

If you cannot find a suitable mask for your child, you can adjust reusable masks or make your own out of fabric or similar materials.


If you have shortness of breath and find that wearing a mask makes the problem worse, you may be more vulnerable to serious COVID-19 infection. 

In this case, you should stay at home as much as possible, and avoid going out unless necessary.

According to medical experts, some groups may have difficulties when using face masks, including children with special needs and even children older than two.

MOH said that it would "exercise flexibility in enforcement for these groups".
