Graphene in Face Masks: What You Need to Know

At The Canadian Shield we pride ourselves on giving transparent, up-to-date information in order for our customers to make informed purchasing decisions.

Recently, as you may have seen on the news, Health Canada released an advisory notice urging Canadians not to use face masks with graphene or biographene, citing risks associated with inhaling graphene particles. After undergoing “preliminary assessment”, graphene particles have shown “some potential to cause early lung toxicity in animals”. This advisory was issued after face masks containing graphene, which were manufactured overseas, were distributed in Quebec schools.

The Canadian Shield Face Masks are not affected by this advisory, and do not contain graphene of any kind. This includes our Medical-Grade & Unrated Procedural Masks as well as our Semi-Reusable Face Masks.

As one of Canada’s largest manufacturers of personal protective equipment, equipping our customers with reliable, safe and high-quality products is of utmost importance to us.

What You Need to Know

Important information about graphene in face masks:

  • Graphene or biographene, is a new nanomaterial or material made of tiny particles
  • Recently, in the medical mask manufacturing industry, this additive was used to try and give face masks antiviral or antibacterial properties
  • Antiviral or antibacterial masks are face masks most often made with a material additive designed to kill viruses or bacteria upon contact
  • This graphene additive can be layered onto the polypropylene material used to produce face masks during the manufacturing process, and can result in a black/grey colouring
