From the same article regarding the safety issue of Metalifer masks:

"Until Health Canada has proven that it is completely safe to use nanoform graphene in masks, Thomas believes no one should take any chances.

“What we know about graphene flakes, which is what this probably is,” he said, “is that … generally speaking, it’s not a good idea to inhale nanoparticles.”
