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. The agency is advising people not to wear masks with graphene or biomass graphene because its preliminary assessment of the available research suggests the particles cause early lung toxicity in animals, though the risks to humans are not yet known. This advisory was issued after face masks containing graphene, which were manufactured overseas, were distributed in Quebec schools.

As a manufacturer, equipping our customers with reliable, safe and high-quality products is of utmost importance to us, therefore it is our duty to inform and reassure you that all our masks are made with safe materials and therefore do not contain graphene of any kind.



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.
