The Canadian Shield ASTM Medical-Grade Face Masks

Face Masks

ASTM F2100-20 Compliant - Level 1, 2 & 3

Medical-Grade Procedural Face Masks

The Canadian Shield's disposable procedural face mask line is 100% Canadian-made.

Level 1, Level 2 and Level 3 Masks feature three layers: a moisture-absorbent inner layer, a high-efficiency filtration layer, and a moisture-repellent outer layer. Masks are constructed with polypropylene for full coverage of the nose and mouth. Our disposable masks are 100% polypropylene, so they're latex and fibreglass free. Ear loops are 70% polyester and spandex.

The Canadian Shield's products do not contain graphene of any kind.

The Canadian Shield ASTM Face Mask Selection Guide


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.

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.
