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.
Wearing a mask should be combined with other important protective measures such as frequent
hand washing and
physical distancing. A mask is not enough to prevent the spread of COVID-19 on its own.
The information on this page is for the public. Health care professionals should refer to information about
personal protective equipment for health care settings.

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.
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.

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
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 taking your mask off.
- 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.
