March 29, 2020

Fabric face masks sold at wet markets in Toa Payoh, Tiong Bahru, Clementi and Compass One shopping mall shop in March 2020.  They do not have a core filter but some claim to be 3-ply. The 3-ply or 3 layers are all fabric as filters are expensive and will cost more.

to be moisture repellent on the inner and outer surfaces. It is comfortable, easy to breathe, andwashable. 
It has no chemical smell or is irritating to the face as compared to many disposable 3-ply surgical masks
presently sold in retail shops in Singapore in April/May 2020.

This mask has a centre moisture repellent filter.  Why is this important?

The moisture repellent filter in this mask passes the WATER TEST. When you place a drop of water or 10 ml of water onto the inner surface of the mask, there is no leakage. You repeat the test on the outer surface. There is also no leakage as the mask contains the water.

Moisture refers to traces of water. If the filter repels moisture, it will protect the wearer from the splatter of respiratory or blood droplets from another person who sneezes and coughs at close quarters. The mask's outer surface repels the droplets.

If the wearer has coughs, his or her respiratory droplets will not pass through the inner surface as the filter repels the droplets, preventing them from landing onto the other person's face. This is especially important to protect family members or others in a COVID-19 outbreak as the coronavirus (Covid-19) is transmitted by respiratory droplets even from a person who looks well and has no symptoms.
