Counterfeit mask or not?
There have been experts popping up all over claiming to know why one mask is fraudulent over another, why one mask is better than another.
Life Biotech has proudly partnered with high quality manufacturers who match the core foundational ideals that many have come to respectfully know and trust.
Our KN95 masks are all tested and credited to GB2626 standards via a CNAS approved facility. As a result, legally these masks can claim the standard KN95. Additionally, further testing has been undertaken via Intertek to ASTM standards demonstrating that they are also level 3 certified surgical masks. These test reports are available upon request.
Recently it has been highlighted that to discredit a KN95 mask, there is a test of pulling against the straps demonstrating its inferior quality or lack of tensile strength as they would either withstand or snap accordingly. Unfortunately, some have demonstrated that by pulling against the mask and allowing the welding to separate it demonstratingly proves that the mask is counterfeit, however, no leading expert would use this method of testing pulling against the mask is contrary to the design of the mask and the welding concept. This opposing force of pulling against the mask separates the welding and like all welded adhesions, the bond separates or snaps. On our KN95 mask, the welding of the strap provides sufficient surface tension so that when force is applied, in the direction for which it is designed, the strap will not break or separate from the mask. In the video, while it may be in Chinese, it demonstrates the point of pulling with the weld it can hold 1 kg and pulling against the weld, the weld separates. Unfortunately for those who are promoting the testing method of pulling against the weld, the standard testing method under the Australian, European and USA standards, is to test the welding strength by pulling with the weld. The Homar mask under the brand of S.Sangso and the Medigear KN95 mask, have both been tested under the GB2626 standards and have been found compliant to the tensile strength of N1 or to 1kg of tensile applied pressure. A picture of the mask undertaking this test is also included here.
While we are in a time of crisis, misrepresentation has only added to the stress and confusion of what is suitable and what is not, what is counterfeit and what is real. Caution should be had with those who defame products with concepts and techniques that are against manufacturing designs and internationally recognized and approved testing standards.
