Disposable Masks

ASTM International is the organization that develops and sets the preferred international standard in healthcare for the requirements of the performance of materials. There are more than 12,000 ASTM standards for a variety of products and industries.

A face mask that has been developed to meet ASTM F2100 standards offers the highest levels of protection in four areas: fluid resistance, differential pressure, filter efficiency and flammability. For more information on ASTM ratings, click here.

The Canadian Shield's products, including our Disposable Procedural Masks, BioMask™, and Semi-Reusable Face Masks, do not contain graphene.

The difference between each of these masks is their performance criteria against ASTM F2100 International Standard requirements. 

There are three distinct levels of medical masks in the ASTM F2100 rating system, including ASTM Level 1, ASTM Level 2 and ASTM Level 3 masks. Level 1 masks are the general standard and are best suited for low-risk, low-fluid environments. Level 2 masks are best suited for moderate levels of fluid exposure. Level 3 masks offer maximum barrier protection and are best suited for environments with high levels of fluid exposure. For more information on ASTM F2100 ratings, click here.

Although the body of our Unrated 3-Ply Disposable masks is made of the same 100% non-woven polypropylene material, they are not tested to the same ASTM F2100 performance standards as our Level 1, 2 and 3 procedural masks.

However, each of our masks, including Unrated masks, undergo all of our quality control and quality assurance measures. Our Unrated 3-Ply Disposable masks feature the same great design as Level 1, 2 and 3 masks including an interior meltblown polypropylene layer for maximum filtration. Unrated masks are a cost effective option for low-risk environments where fluid exposure is not anticipated.

According to the CDC, disposable procedural and or surgical masks may not adequately protect against aerosol or airborne particles, primarily because they do not effectively filter small particles from the air.

Personal protective equipment, including face masks and coverings, are worn to provide a barrier and decrease the probability of the wearer being exposed to hazardous droplets or infectious disease.

When worn correctly, PPE may protect against illness by preventing exposure to said droplets. Personal protective equipment is the last line of defence against hazards and is not a substitute for more effective control methods, such as physical distancing and proper hand hygiene.

Masks are 100% polypropylene. Latex and fiberglass free. Earloops are 70% Polyester, 30% Spandex. Our BioMask™ is made up of the same materials, and also includes a proprietary additive which is added during the manufacturing process.

There are no preservatives or chemicals added to our polypropylene masks. All of our raw materials are subject to stringent toxicological and carcinogenic testing to ensure the masks are safe to wear. Based on this testing, our masks are devoid of irritants and are safe for human skin. Our non-woven polypropylene contains trace amounts of blue polypropylene base pellet, which gives the outer layer its blue shade.

Based on toxicological and carcinogenic testing, our materials are confirmed to be irritant free and safe for wear.

Each of our procedural masks features a nose bridge made of steel sealed in plastic in order to create a tight seal and minimize gaps.

According to the CDC, masks become less effective when wet as they are more difficult to breathe through and less efficient at filtering. It is important to have one or more replacement masks during cold, wet weather, including rain and snow. If you are wearing a reusable mask and it becomes wet, put it in a sealed plastic bag until it can be washed. If you are wearing a disposable mask and it becomes wet, safely remove and dispose of the mask and replace with a new, dry mask.

The Canadian Shield’s procedural masks are disposable and are intended for one-time use. Your face mask should be changed when it gets wet, visibility dirty, soiled or torn. Not only is it not possible to sterilize disposable masks, but the material of The Canadian Shield’s procedural masks are also electrostatically charged to filter micro-particles, and this charge is lost over time with wear. We recommend the use of a new disposable mask each day. For guidelines on how to safely remove and dispose of your procedural mask, click here.

At The Canadian Shield, each of our procedural masks are manufactured with one standard size of earloops. Although we have standardized our face masks for universal wear, we understand that one size of earloops doesn't always yield a snug, comfortable fit on all individuals. 

To ensure that your procedural mask fits securely to your face, we have compiled some tips to help you avoid gapping while wearing your mask. To view our guide to adjusting earloops, click here.

The BioMask™ is a medical-grade face mask which contains a proprietary additive that helps it break down in anaerobic conditions such as landfills.

Face Shields

For assembly instructions, please download our instruction guide. Alternatively, you can watch our instructional video here.

Each pack of shields includes instructions for proper assembly and sanitation. If you are not using in your shield in a medical or high fluid-risk environment, your shield may be disinfected using Public Health guidelines. Many of our customers using the shield in commercial or other low fluid-risk settings opt for Lysol or Clorox wipes.

The Canadian Shield was originally designed for healthcare use.  In this use case, our shield was found to perform best up to 15 times.

However, for the average individual, with proper cleaning and care your shields can last far beyond 15 uses. Many of our staff members use the same shield for weeks on end.

The most common problems found with all shields after extended use are scratches. However, our shield is made of 0.017” thick plastic — double the thickness of most shields on the market, which means it has the capacity to last much longer.

We always recommend wearing a mask with your face shield as it will provide the most protection. That being said, for those who cannot wear a mask for medical reasons, a face shield is better than no PPE at all. 

We chose to design our shields without foam at the top to ensure that the entirety of the shield would be disinfectable. Once a foam headband is used, it cannot be disinfected and is therefore not recommended for reuse.

If your shield was damaged in transit, our team will be happy to send you a replacement. Please contact our customer support team with a replacement request by clicking here.

Many dentists and dental hygienists have used our face shields with dental loupes and headlights. If you’re looking for more information about the use of our shields in the dental industry, you can find more information by clicking here.

Yes, our adults and kids face shields are all 100% latex-free.

We recommend the Kids Face Shield for children aged 5-12 years old. Check our size chart for reference.

Cloth Masks

Due to the amazing response we've received for our hand-sewn cloth masks, we are temporarily out of stock of this product.

We appreciate your patience as our team works to re-stock! At this point in time, we do not have an expected date for re-stock. We encourage you to stay tuned on social media and be sure to subscribe to our newsletter for details on when this product has returned to our store.

Check our Cloth Mask size chart for your reference.

Each of our cloth masks include Synergex One filtration. Proper filtration is measured using BFE (Bacterial Filtration Efficiency) and PFE (Particle Filtration Efficiency).

Synergex One is made from a non-woven polypropylene composite, made with unique meltblown technology. It has a BFE of >85% and a PFE of >90% at 3 microns. It's undergoing continuous testing to be rated at >95% BFE. Synergex One filtration was designed in North America and is splash resistant.

Yes. Synergex One is a non-woven polypropylene composite made with meltblown technology.

Our cloth masks do not have a pocket for a separate filter. This is because we've chosen to design 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.

Thread count is a term that’s often exclusive 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. 

We recommend that you wash your mask before your first use, and after each wear.

Your cloth mask should be machine-washed with COLD WATER ONLY as 100% cotton masks may shrink when washed with warm or hot water. Temperature does not matter when disinfecting your mask in the wash as long as your mask is washed with soap.

Tumble dry on low or hang mask to dry after washing. Ensure the mask is completely dry before storing and store in a clean bag or container between uses.

Semi-Reusable Masks

Traditional ASTM-rated masks are disposable face masks made of 100% polypropylene which have been tested to comply with ASTM F2100 requirements for medical-grade masks. ASTM-rated masks are available in three levels, Level 1, 2, & 3, and are designed to be used in medical environments. 

The Canadian Shield’s Semi-Reusable Face Masks are made with a heavier-weight GSM (Grams Per Square Metre) of 100% polypropylene non-woven material, allowing it to be reused with proper washing and care. While it is still considered an unrated mask, our Semi-Reusable Face Masks are designed and tested to withstand up to 10 washes in a regular wash cycle. 

Please note, while both ASTM-rated masks and unrated Semi-Reusable masks are made with similar material, Semi-Reusable Face Masks have NOT been tested to meet the same ASTM F2100 standards. Furthermore, different variables such as laundry detergent, water temperature, and other factors can affect the filtration efficiency and durability of the mask. The Canadian Shield always recommends following the included washing and care instructions which accompany all Semi-Reusable Masks. For individuals in environments where there is a moderate to high risk of fluid, spray, or aerosols produced, disposable ASTM-rated medical-grade masks are the best line of defense combined with social distancing and other PPE.

While The Canadian Shield uses very similar 100% polypropylene non-woven materials for our Semi-Reusable, these Semi-Reusable masks have NOT been tested to meet ASTM F2100-20 requirements for medical-grade masks. It is therefore only considered an unrated mask and should not be used in environments where fluid exposure is of high risk.

Furthermore, different variables such as laundry detergent, water temperature, and other factors can affect the filtration efficiency and durability of the mask. The Canadian Shield always recommends following the included washing and care instructions which accompany all Semi-Reusable Masks. For individuals in environments where there is a moderate to high risk of fluid, spray, or aerosols produced, disposable ASTM-rated medical-grade masks are the best line of defense combined with social distancing and other PPE.

The Canadian Shield’s Semi-Reusable Face Mask is made up of three layers of heavy-weight 100% non-woven polypropylene. The outer two layers are 50GSM non-woven polypropylene, and the inner filtration layer is 25GSM non-woven polypropylene. 

The head strap on the Semi-Reusable Face Mask is a durable and stretchable elastic cord made of a polyester exterior and rubber inner core. 

The nose bridge on the Semi-Reusable Face Mask is made of a thin wire of steel coated in plastic.

The Canadian Shield recommends our Semi-Reusable Face Mask is washed and reused up to 10 times using a normal wash cycle.

• Hand or machine-wash - gentle settings are recommended for machine washing
• Hang or lay flat to dry, do not tumble dry
• Do not iron
• Ensure the mask is completely dry before storing and store in a clean bag or container between uses.

The Canadian Shield recommends our Semi-Reusable Face Mask for individuals aged 8 years and older. While the head strap design of the mask does make it fully-adjustable, the mask body is designed for an adult face and may be too large on a child under 8 years of age. Please refer to the mask body dimensions below for exact measurements.
