Mask Protection Efficiency [Infographic]

Our wonderful graphic designer Janella Quizon has created this super useful infographic. It shows you the efficiency of different face masks as a way to protect yourself during the coronavirus (COVID-19) pandemic.


It is easy to assume that because a brand tells you that wearing their product will protect you, you trust them and buy it. But take a look at the cloth and sponge masks above and see that in reality, they are doing almost nothing to protect you.


Let's take a closer look: 


KN95 Mask

The KN95 respirator mask is used to prevent the user from inhaling small airborne particles in aerosol-generating procedures (AGPs) - procedures that stimulate coughing and promote the generation of aerosols. It must fit tightly to the user’s face. It is recommend that this mask be worn with eye protection and ideally a face shield. There are three categories: FFP1, FFP2 and FFP3. FFP3 provides the highest level of protection. 


3-Layer Mask

The standard 3-layer surgical mask is also known as a fluid-resistant surgical mask (FRSM). The mask is designed to provide a barrier to droplets which can adversely affect the wearer’s nose, mouth and respiratory tract. It fits fairly loosely to the user’s face in comparison to the KN95 mask. These single-use masks are used for a variety of procedures in community as well as hospital settings. They should be changed when they become moistened or damaged. 3-layer surgical masks should be worn with eye protection. 


Cloth Mask 

Cloth mask

Homemade cloth masks should only be considered as a last resort to prevent droplet transmission from infected individuals. The World Health Organization (WHO) has advised that these type of masks do nothing to prevent transmission of coronavirus (COVID-19). 


With your life literally on the line, it is better to opt for a mask that can protect your nose and mouth from coronavirus and other airborne viruses. The KN95 is the best option if you work in a hospital or are in close proximity to people who are sick. A 3-layer surgical mask is a good option if you are returning to work.
