How to check if your face mask is effective?

The global demand for face masks had outstripped much of its supply, causing traditional mask distributors in Singapore such as Watsons, Guardian and supermarkets to have completely run out of stocks. Many consumers have taken to various online platforms such as Qoo10 and Lazada to get hold of masks in response to this shortage.

However, a recent news article on Straits Times[1], demonstrated that a staggering 5 out of 6 face masks including ones that had been given to taxi drivers, had failed to pass quality checks. In light of this article, as well as the severity of the potential implications that wearing an ineffective face mask might pose, one might begin to wonder – how do I check if the mask that I had purchased is of good quality?

Here are some methods as demonstrated by Wellchem Pharmaceuticals director in a video by The Straits Times[2], which can be used to verify the quality of your face masks.

1. Visual inspection – face masks should have 3 layers that are not too thin
   
2. Water repellence – face masks should have an outer layer that is able to repel water
   
3. Flammability – face masks should not catch fire or leave any residue when burnt with a lighter
