I think there is more confusion....Here is a description of what Level means as per face masks....Face masks are not to my knowledge designated by class medical device...they are classified by Level for a face mask protection

Surgical masks are generally graded through ASTM (American Society for Testing and Materials), who publish technical standards for products, materials, systems and the likes. There are currently around 12,000 ASTM standards in use.

Not all masks are graded so make sure you check that your product of choice has an ASTM grade or is from a reputable manufacturer. This will ensure you are comfortable that you have the appropriate level of protection, and thus minimising the risk in your workspace, whether it be surgery, pathology, or research. Ensure you find masks which have the ASTM level printed on the box, with the level of fluid resistance (see table below) shown. If this is not present, the masks are non-compliant with Australian standards and regulations.

Which is which?
Level 1: Low barrier protection General use. Not used for aerosols, spray or fluids.
Level 2: Moderate barrier protection For low to moderate levels of aerosols, spray and/or fluids
Level 3: Maximum barrier protection Used for high risk of fluid, spray or aerosol exposure

westlab.com.au

There is no such thing as a LEVEL 3 MEDICAL DEVICE...when tested to ASTM standard the masks are tested to a LEVEL of protection from an aerosol or spray or fluid. Note: there is no mention of any testing for toxicity of the mask material.


Now I doubt when they submitted their masks for the ASTM tests, they did not submit data on the toxicity of Graphene on the user... it would not have been a criteria in the ASTM tests for face masks.

to say Graphene particles are non toxic is not necessarily true

This is an article discussing Graphene and its potential toxic nature

assessment of the Toxic potential of Graphene Family Nanomaterials

Now since Health Canada probably did not test for toxicity of breathing graphene particles while wearing the mask... I can see them issuing a recall until those tests were conducted and a decision made on the product

FINALLY

The internet article I read did not address the ZEN product specifically... it was a blanket recall of all face mask that use Graphene nanotechnology and I believe there are Chinese masks that use this technology

The agency will test all to see if any have a problem. Personally I think that is wise.
