COVID-19 Supporting Your Practice

Helping You Identify Counterfeit N95 Masks

Counterfeit, sub-standard and non-equivalent N95-like respirators are flooding the marketplace as the demand for N95 respirators continues to rise. These products have not been certified and will not deliver the same respiratory protection as N95 respirators, which are certified by the U.S. National Institute for Occupational Safety and Health (NIOSH).

Dr. Aaron Burry, Associate Director of Professional Affairs at CDA and the Staff Lead on COVID-19, sat down with me to explain how dentists can identify a counterfeit mask and show the most recent resource available on the CDA website that helps dentists learn important facts about counterfeit, sub-standard and non-equivalent N95 respirators/masks.

    Thanks for the great discussion. There are loop holders for the back of the head. Does that increase the tightness of the other masks and therefore the higher likelihood of them getting to 95% efficiency?

    1. Vasant Ramlaggan May 21, 2020

      So to answer my own question: I found out that the mask loop holders do indeed improve the fit test. It may or may not get to 95% efficiency depending on the mask type (KN95s are not getting good results) and the right size for each person. Don’t keep getting fitted unless you know you have a good supply of the same type of masks or you (and your team) will have to be fitted for each new model.

    This is very well done, but would be better with a list of where we can buy the appropriate masks, and therefore we don’t waste our time with other sources.
    Thanks for the work you have done, but we are no closer to opening the offices if doctors and staff and patients do not perceive it to be safe to do so.

    “N95 mask alone takes a minimum of 3-5 mins to put on and self-test ”

    Thank you Dr. Aaron Burry for the information and thank you Dr. Chiraz Guessaire for arranging this important and informative conversation with Dr. Burry. I personally think that COVID-19 crisis has been an eye-opener in many aspects. I think that as a well-developed and advanced nation and country, it is time to think about having PPE manufacturing here in Canada instead of importing it form other countries, either run by private sector or at a federal level. Not only it would create jobs, and would eliminate the need of importing them, but also we wouldn’t be worried about their authenticity of the product, since they are being made here on our soil. PPE usage is a never-ending need regardless of this crisis, hospitals, medical clinics, dental clinics, and many other health care establishments utilize PPE on daily basis. It could also be exported to countries of need; therefore, it could be great source of income for the government or anyone who owns the manufacturing. Just a thought.
