Revised mask-wearing requirements at our Medical Centre and Hospital

N95 or Surgical Mask for COVID-19 Protection?

Published on: Jan 31, 2020

With the recent COVID-19 outbreak, both N95 and surgical masks have been flying off the shelves at many stores.

N95 masks, as the name suggests, blocks out 95 percent of very small (0.3 micron) particles or pollutants in the air. Due to its nature, they are very effective in times such as the haze situation that we had experienced in the region. However, N95 masks must be rightly fitted for it to be effective, and users may feel stuffy with the mask on.

Surgical masks, on the other hand, are effective in blocking out water particles and splatter. They work by protecting your mouth and nose from the droplets that may be in the air when an infected person sneezes. The surgical mask is also more comfortable and practical to be in, making it the recommended option for the general public.

Protecting myself. What to look for when purchasing surgical mask?

“When purchasing any surgical mask, you should read the labels and ensure that they are 3-ply. 3-ply masks comes with 3 layers to provide protection for the wearer,” said Assistant Nurse Clinician (Infection Control) Ms Li Juan Li. The masks has:

  • Coloured surface, which is usually blue or green in colour. This surface is waterproof and should be worn facing-out
  • Middle layer, which acts as the filter for the mask
  • White surface, which should be worn internally facing
  • It helps to absorb moisture for the wearer’s comfort
     

When should I wear a mask?

It is generally not necessary for a healthy individual to put on a mask. However, you may consider wearing one if you will be in an enclosed area with other people, such as when you are on public transport like a bus, train or car.

“If you are feeling unwell or displaying any symptoms such as fever, cough, or shortness of breath, you should wear a mask and visit a doctor immediately,” she added. Wearing a mask helps to contain the spread of the virus and reduces their risk of exposure.
 

Observing Hygiene When Using Surgical Masks

As an end note, Ms Li said there are also personal hygiene practices to observe when using surgical masks. They are:

  • Wash or sanitise your hands before putting on AND after removal
  • Wear the mask with the coloured surface facing out
  • Avoid touching the coloured surface when you are removing the mask as it will be contaminated
  • Change the mask if it feels wet, dirty or whenever necessary
