Very concise lab presentation.
If the kn95 materials are up to performance, wouldn’t basing performance on more layers just show material inferiority and increase the air resistance? Granted, Huheta did make the claim of layers present.

Thank you!

Should I be concerned that these masks have GB2626-2019 printed on the box only? It is not printed on the masks themselves. About a year ago (February 7, 2022) Huheta-US replied to someone’s question regarding this issue that the GB2626-2019 had not been “printed on the mold at that time”, but they would “add GB2626-2019 on the mask later”.

Thank you for the video.I believe these masks pass the airflow resistance, because 206Pa <210Pa which is the limit .I believe they fail, because they don't have the correct markings printed on the masks, such as GB2626-2019 and the manufacturer name.
