Question 1

Does this KN95 mask have individual serial # on it. I was told that is how you can tell that they are real and not a knockoff

Accepted Answer

These masks are listed as a "Counterfeit Respirator / Misrepresentation of NIOSH-Approval" by the CDC on their website.  The CDC website states: "Chengde Technology Co., Ltd. is misusing NIOSH test information regarding WWDOLL model CD9501B KN95 Foldable Protective Masks. The product package indicates it meets Chinese standard GB 2626-2019 and was submitted to NIOSH under an International Respirator Assessment request. It is being marketed using results from the assessment. As stated on the NIOSH website, these results are not to be used by manufacturers, distributors, suppliers, and importers to make claims about their products and/or to influence purchasers and cannot be used to make claims that the product meets NIOSH approval requirements. Chengde Technology Co., Ltd. is not a NIOSH approval holder or a private label holder. (2/18/2021)" - U.S. Centers for Disease Control and Prevention

Question 2

Disclaimer: this kn95 mask is not an n95 mask.
(why is this important detail provided in fine print?)

Accepted Answer

An n95 mask is extremely tight and usually reserved for health care professionals. The Kn95 is the next step down but is comfortable and wearable for regular everyday use. It’s a quality, high filtration mask. Even some healthcare professionals use the  while treating patients. I am a practicing dentist and wear the N95 masks daily while treating patients, but outside, I wear the kn95 masks. Hopefully this helps answer your question.

Question 3

are the masks individually wrapped in sealed packets? thanks very much for your response.

Accepted Answer

Hi,one package contains 5 small bags, a small bag contains 10 masks, a total of 50 pieces of KN95 masks

Question 4

Do they stay put when you yawn?

Accepted Answer

For me they do as long as it's secured in the right place on the bridge of your nose, not towards the tip.
