I would give this product one star except that I don't have any hard evidence to support my concerns. However, I don't believe these are real KF94 masks. I didn't review the product listing very carefully before purchasing because they were Revain's product of choice and I mistakenly trusted Revain's recommendation. I would summarize my concerns as just suspicious that they are fraudulent. Didn't know they were made in China until they arrived and saw the label on the box. My research on the KF94 standard has shown that it is a Korean standard and that the masks are manufactured and controlled by Korea. The overall quality of the product was just really bad. Everything from the box to the plastic packaging to the look of the masks themselves was anything but comparable to two other KF 94 masks I've bought in the past such as the. B.Dr. puri I am writing this review out of concern for the safety of others.
