Is your N95 Mask Authentic?

Published on July 30, 2021

The N95 masks are lifesavers in current COVID-19 times. The masks, which were designed to protect industrial workers from breathing fine dust particles at their workplace, have taken centerstage in preventing COVID-19 infection, especially in high-risk areas such as hospitals.

But is the N95 mask bought from your neighborhood shop or ecommerce website authentic? With the surge in demand for the masks, fake products have found their way into the market. Some go a step further and claim to be approved by regulatory bodies such as the US National Institute for Occupational Safety and Health (NIOSH) and the International Standards Organization (ISO), sometimes even presenting approval numbers to make their claim sound impressive!

Fortunately, there are ways to check if the certification of an N95 mask is authentic. Some regulatory bodies that certify the masks list the approved products on their websites. For example:
