The Public Health Agency of Canada recommends wearing a 3-layer, non-medical mask or face covering in public places, especially crowded places, when physical distancing is not possible. 

This includes places such as shopping malls, grocery stores, workplaces and public transit. 

When worn correctly, these masks can reduce the spread of respiratory droplets to others.

How do I use the mask?
Wash your mask before first use and after each wear. 

To wear your mask, follow these steps:

Insert your head through the bottom portion of elastic, wth the inside of the mask facing up. Next, with one hand holding the outside of the mask, use the other hand to grab the top portion of elastic and pull it over your head.Adjust the cord stopper to create a snug but comfortable fit around your head. Lastly, press the metal stiffener against your nose to create a tight seal around your face.

What are the specifications of the interior filter layer?
Our cloth masks feature Synergex One filtration. Synergex One is a a non-woven polypropylene composite made with unique meltblown technology. It has a BFE (Bacterial Filtration Efficiency) of >85% at 3 micron and >90% PFE at 3 micron. It’s a splash resistant material designed in North America!

Can I add an interior filter layer?
Our cloth masks do not have a pocket for a separate filter. We’ve chosen to make our masks with Synergex One filtration, a high-end interior layer that offers superior protection against airborne pathogens. For this reason, our cloth masks feature a closed seam around the filter layer and do not include a pouch to insert additional filters.

What size cloth mask should I purchase?
Please refer to our sizing chart for a breakdown of our small and large cloth mask sizes, including measurements. These masks are designed to be unisex, but we would recommend most adults opt for size large. Small masks are suitable for youth and petite adults.

Why do my masks vary slightly from one another?
You may notice some uniqueness in your masks as they are hand-sewn in our Waterloo, ON facility by real Canadians we're employing during the pandemic. If you feel as though there is a significant discrepancy in your size, please contact our customer support team to let us know.

Can I order your masks in bulk?
Yes! Our team would be happy to speak with you about a bulk order inquiry. If you are interested in ordering 100 units or more, fill out our bulk order inquiry form.

What materials do you use in your cloth masks?
Our cloth masks are made with 100% cotton fibers treated with non-hazardous dyes and chemicals. 

What is the thread count on your cloth masks?
Thread count is a term that’s most often used in reference to bed linens, while most fabric materials are measured by their GSM, or Grams per Square Meter. GSM is the weight of a fabric if you take a sheet of material which is one meter by one square meter and weigh it in grams (g/m2).

Strictly speaking, there is no comparison to be made between GSM and thread count. The GSM of our Reusable Cloth Masks is 170 +/-5% and our cloth fabric is 100% cotton. A medium weight GSM is 150-350 GSM and heavy weight is considered to be 350+ GSM, such as PVC.

How do I care for my mask?
The entirety of your mask, include the head strap, are designed to be washed between use. Hand or machine wash your mask with COLD water after each wear. Our masks are made with 100% cotton for comfort and breathability, but will shrink if washed with warm/hot water.  Tumble dry on low or hang mask to dry. The choice of whether to iron your cloth mask is up to your discretion.

Will washing my mask on "cold" kill bacteria?
As long as your mask is hand or machine washed with soap, your mask is safe to wear after washing with cold water.

Are the masks breathable?
Yes, our cloth masks are designed with 100% cotton for breathability and comfort without sacrificing on protection. When designing our masks, we worked with multiple healthcare professionals who advised that 100% cotton is suitable material for filtration and consumer use. 

When should I wear a cloth mask?
According to the Public Health Agency of Canada, wearing a mask is recommended in scenarios where it is not possible to consistently maintain a 2-metre physical distance from others, particularly in crowded spaces such as stores, shopping malls and public spaces. In some public jurisdictions, the use of masks in indoor spaces is now mandatory. 

Will this cloth mask protect me from the virus?
When worn properly, a person wearing a non-medical mask or face covering can reduce the spread of his or her own infectious respiratory droplets. Cloth masks are most effective in reducing the spread of illness when used widely by people in public settings. 

Please note that cloth face masks are not a replacement for medical grade Personal Protective Equipment and that this mask is not intended to replace other recommended measures to prevent the community spread of illness. Cloth face coverings are an additional step to help slow the spread when combined with every day preventive actions, including frequent hand washing and physical distancing in public settings.
