Frequently Asked Questions
Q: What is a KN95 mask and how does it compare to an N95 respirator mask.
A: N95 masks are manufactured to meet a certain U.S. test standard defined by NIOSH (National Institute for Occupational Safety and Health). The 3M company is probably the best known for their N95 respirators in the U.S. KN95 masks are manufactured in China and certified against a similar standard. Until April 2020, the FDA did not approve any KN95 masks for use by health care providers. This link to a 3M document compares the different respirator face pieces in this class.
Q: Can masks approved under standards used in other countries, such as KN95, be used in the US during the COVID-19 pandemic?
A: Yes. This link to the FDA website provides specific guidance on the use of KN95 masks during the pandemic.
Q: How do I know if the KN95 mask I buy meets the certification standards.
A: Our KN95 masks are sourced from reputable manufacturers in China that are registered with the U.S. FDA. In addition, we require documentation from the manufacturer that the respirators they produce meet not only the Chinese standard, but the European CE EN149 standard.
