Procedural Masks

Procedural masks are breathable, lightweight masks designed for one-time use. The Canadian Shield offers a full line of procedural masks, including ASTM Level 3, ASTM Level 2, ASTM Level 1 and Unrated 3-Ply Disposable Masks.

PROCEDURAL MASK FEATURES

Comfort: Our mask’s inner layer is moisture absorbent, soft and non-abrasive for a comfortable fit.

Breathability: Our mask’s middle layer offers high-efficiency filtration from harmful particles without sacrificing breathability. 

Protection: Our mask’s outer layer is moisture repellent, acting as a fluid barrier. Pleated polypropylene provides full coverage of the nose and mouth. 

Tight Seal: Added nose stiffeners ensure a tight seal to minimize gaps.

WHAT ARE ASTM RATINGS?

Procedural masks are often labelled by their ASTM rating, a certification that measures the performance of the masks against technical standards laid out by the American Society for Testing and Materials. ASTM Level 1, 2 and 3 masks are designed for use in medical environments and should be reserved for frontline workers in environments where exposure to hazardous fluids a risk.

BREATHABLE & RELIABLE

TRIPLE-LAYER DESIGN

Each disposable mask features 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. 

PROCEDURAL MASK FAQ

Q: What is the difference between a procedural mask and a surgical mask?

A: Procedural masks are characterized by an ear loop attachment and a coloured outer layer. Traditionally, they are designed for use outside of operating rooms. They protect patients and staff from transfer of respiratory droplets by coughing, sneezing or talking.

Comparatively, surgical masks are intended for operating rooms and are characterized by surgical ties behind the head and closeness of fit. They are designed to protect the clinician from contaminated fluid or debris generated during procedures.

Q: When should an ASTM rated procedural mask be used?

A: ASTM rated masks should be reserved for medical environments and work performed by healthcare or allied healthcare workers. ASTM rated masks have been tested to ensure protection against moderate and maximum levels of fluid exposure.

Q: Are 'unrated' procedural masks safe?

A: When purchased from a trusted source, unrated procedural masks are safe for everyday consumer use in low risk environments, such as shopping malls, grocery stores or public transit. The material used to produce an unrated disposable mask and an ASTM rated mask is the same - the unrated mask simply has not undergone the same testing standards required for medical environments. This level of testing is not required in order for the mask to be effective and safe for everyday use, meaning unrated masks are an affordable, suitable face covering alternative for the general public.
