Facemasks will help protect you and those around you and are required in some settings.
: February 18, 2021
Masks have a role to play in preventing the spread of COVID-19. Masks act as a barrier and help stop the spread of droplets from a person’s mouth and nose when talking, laughing, yelling, singing, coughing, or sneezing.
Masks help protect you and the people around you when you are sharing a space with people you don’t live with. They work best when everyone who can wear a mask is wearing one. Wearing a mask should be combined with other important protective measures such as:
Masks are most effective when fitted, worn and handled correctly. Masks should:
- Cover the mouth and nose and go under the chin
- Fit tightly with no gaps (consider adjustable masks)
- Be made of three layers of fabric, including two layers of tightly woven fabric, with a filter or filter fabric between layers.
- If there are two layers with a pocket for a filter, use a filter

When to wear a mask
A properly fitted mask sits closely over the mouth, nose, cheeks and chin of the person wearing it.
- It is important to make sure the mask can be held in place comfortably with ties or ear loops to reduce the need to adjust the mask. If it is not comfortable, you won’t want to wear it consistently.
- Masks should only be used by one person and should never be shared.
- Wash or sanitize your hands before and after putting on and taking off a mask.

If you are making a mask, here is some information to help make an effective mask:
- Homemade masks can be made from different materials, but some materials are better than others. Use clean 100% cotton, polyester or a cotton-polyester blend.
- Homemade masks should have at least three layers to make sure that droplets don’t pass through the fabric. The most important thing is having these three layers with a mask that fits well.
Here are some instructions on how to make cloth masks: Non-medical masks and face coverings: Sew and no-sew instructions
Face shields do not replace non-medical masks. Face shields are commonly worn with a mask underneath for extra protection and are used to protect you from oncoming splashes and sprays.
The design of the face shield does not necessarily protect other people as it may not block all of your droplets or spray, which can escape from the bottom or sides of the shield. The BC Centre for Disease Control does not recommend the use of face shields as a substitute for masks.
Your employer may ask you to wear a face shield as extra protection. The face shield should not replace other prevention measures such as physical distancing, hand hygiene, barriers, and non-medical masks.
- When communicating using lip-reading, when visual facial cues are essential, or when people may be unable to wear a mask due to a medical condition, a face shield may be an alternative to no mask.
- Some face shields may provide better protection than others. When needed, use face shields that wrap around your face and extend below the chin as well as hooded face shields.
- Non-medical clear masks that cover the nose and mouth are another option when visual communication is necessary. These options have not been widely assessed for their effectiveness.
A mouth shield offers even less protection – these shields extend upwards from the chin instead of downwards from the forehead and usually only cover 2-3 inches of your face; therefore, mouth shields are not recommended.
Medical masks should not be cleaned and reused because putting them in the washing machine may damage the protective layers, reducing their effectiveness. All masks should be changed frequently. Fabric masks should be cleaned frequently. If a mask is wet or visibly dirty it should be thrown-out or cleaned. A wet mask should not be used for an extended period of time.
To dispose of medical masks after use:
- Wash or sanitize your hands before and after taking your mask or face shield off.
- Disposable face shields should only be worn once.
- Put the used masks in a garbage bin. Do not litter.
- After taking off your mask, wash or sanitize your hands again.
- When emptying garbage bins, don’t touch used masks or tissues with your hands. All waste can go into regular garbage bins.
Homemade or cloth masks should be cleaned and changed often:
- To clean a homemade cloth mask, wash it using the directions on the original material. You can wash by hand or in a washing machine. Warmer water is better. Dry the mask completely.
- If dirty cloth masks have been in contact with someone who is sick they can still be washed with other people’s laundry.
- Any damage, fabric break down or change in fit will reduce the protection of cloth masks.
- Reusable face shields should be cleaned and disinfected after each use.
COVID-19 is spread through infected droplets from a person’s mouth or nose. Some people can spread the virus when they have very mild symptoms or may not know that they have COVID-19.
- Wearing a non-medical, cloth mask, is now
required in many indoor public spaces by people 12 years and older. This includes shopping malls, grocery stores, community centres and on public transportation or in taxis and ride shares. It is required in retail settings and restaurants and coffee shops except while eating or drinking. This requirement applies to both staff and customers in these settings.
- Masks are required in common areas of sports and fitness centres when not engaged in physical activity, in post-secondary
institutions, non-profit organizations and in hotels and court houses.
- Masks are strongly recommended in common areas in workplaces and apartment buildings like elevators, hallways and washrooms. Employees may not need to wear a mask in their offices or cubicle if there is a physical barrier like plexiglass in place. Individual workplaces may have further mask requirements that you should follow.
- Wearing a medical mask is required for patients, clients and visitors to most health care facilities such as hospitals. Medical masks are usually provided if you don’t have your own.
People who cannot wear a mask or who cannot put on or remove a mask on their own are exempt. Some people cannot wear a mask for psychological, behavioural or health conditions. Some people may also need to remove their masks to communicate due to a hearing impairment. Be respectful of people who can't wear a mask.
- Non-medical masks may not be required where COVID-19 safety plans and measures like cohorts and health checks are in use such as in classrooms.
- If you are sick and cannot distance from others at home, a mask should be worn. Learn more about the
precautions you should take if you are sick.
- Wear a medical mask if you are caring for a person with symptoms of COVID-19. This is particularly important if you will be in direct contact with a sick person’s droplets, saliva or other bodily fluids. For more information see the
guide for caregivers and household members of those with COVID.
Do not put a face mask or any covering including visors and eye protection on infants under two years of age. A facemask or covering will make it difficult for a baby to breathe because their airways are still small. There is also a risk that parts of the facemask, visor or eye protection can come off and become a choking hazard. See information about
keeping your baby safe during COVID-19 from Perinatal Services BC.
