How to choose your washable face mask with the Dr. Préville-Ratelle | Nathon Kong

Hundreds of non-medical masks have been created during the COVID-19 pandemic. We all want to protect our communities and ourselves from the coronavirus disease, but with so much information available, it can be difficult to learn what makes an effective face mask.

We asked Doctor Sébastien Préville-Ratelle, a specialist in pulmonology working at CIUSSS de l'Est-de-L'île-de-Montréal, for his advice on how to put on, wear, and take off a face mask, what makes them effective, and to review some existing washable face masks.

How Are Masks Effective Against the Coronavirus Disease?

Doctor Préville-Ratelle stresses that wearing a face mask is effective against spreading the coronavirus disease.  

The goal of wearing a face mask isn’t so much about protecting yourself but about protecting others from the disease if you have it.

- Doctor Préville-Ratelle

COVID-19 is a respiratory disease and is transmitted through microscopic water droplets exhaled by people infected with the virus. Not everyone who is infected shows symptoms. According to the World Health Organization (WHO), 80% of infections are mild or entirely without symptoms. New research shows that asymptomatic and presymptomatic transmission is a major factor in how the COVID-19 virus spreads. By wearing a face mask, you prevent yourself from accidentally spreading COVID-19.

Many doctors are calling on the government of to make wearing a mask in public spaces mandatory. New studies are showing that wearing a mask is most effective in preventing coronavirus from spreading when worn by at least 80% of the population. If fewer than 80% of a population wears a mask, its effectiveness is greatly reduced.

What is the Proper Way of Wearing a Face Mask?

The most important thing to do before putting on a face mask is to wash your hands. Doctor Préville-Ratelle recommends that you pick up the mask by the straps. This allows you to put the mask on without touching the front or the back of the mask or your face. Masks with elastic cords that go around the ears like Nathon Kong’s silk face mask are the easiest to put on this way. Then you adjust the front of the mask so that it fits comfortably on the bridge of your nose and under your chin.

To take off the mask you should remove it by the straps and avoid touching the front or the back of the mask. It is important to wash your hands after putting the mask aside.

WHO has useful infographics that show the proper way of putting on and taking off the mask, which can be found here.

According to doctor Préville-Ratelle, being able to breathe through the mask is important. If a mask is too thick, breath escapes around the sides of the mask rather than filtering through it. Thicker masks are also rigid and uncomfortable to wear for long periods of time.

Lighter masks can have their flaws, too. While they are easier to breathe through they may only have one layer of fabric. Doctor Préville-Ratelle recommends wearing a mask with at least two layers to work as a filter. Masks with one layer may be more flexible but many are not made out of premium materials. The mask will not fit well around the face and will not be comfortable throughout the day.

These guidelines fall in accordance with much of WHO’s technical advice on how to wear a face mask.

To begin, Doctor Préville-Ratelle discusses the use of premium materials in the mask. The mask can be washed and reused. He also comments that silk is a good choice of material for face masks. Silk accumulates less moisture than other fabrics. With less moisture in the mask it can be tolerated for longer periods of time.

The combination of silk and cotton also makes a very effective filter. Premium cotton’s high thread count works as a physical net for capturing airborne particles. The electric charge of silk creates an electromagnetic filter, capturing particles magnetically.

We have an article that goes into further depth on the materials used for our silk face masks here.

Nathon Kong silk face masks have two layers of material. Because the masks are made out of premium materials it is still light and easy to breathe through. The government of Canada recommends that a non-medical face mask should have at least two layer while WHO recommends three. If you would like to add a filter as a third layer, there is a pocket in between the front and back of the mask where one can be added. Doctor Préville-Ratelle recommends coffee or vacuum filters. You can even add a medical mask if you have access to them.

Another feature of the mask is its reversibility. Should you want to wear a more conservative mask, Nathon Kong silk face masks can be reversed to show the black side of the mask and have the art on the inside.

To finish his review, Doctor Préville-Ratelle comments on the nose clip. Nathon Kong silk face masks come with a metal wire sewed into the top of the mask. This allows the mask to be adjusted so that it fits comfortably on the bridge of the nose to keep it from sliding off. Because the mask stays in place on the face, it is comfortable to wear glasses with a Nathon Kong silk face mask.
