X6 Half-Face Respirators - TPU version
Description
Following the COVID-19 epidemic worldwide, there is very high demand and tight supply of surgical masks thus cause the high cost all over the world. To combat the shortage of surgical masks amid the COVID-19 pandemic, searching for alternative is demanding. To alleviate the problem, I design a 3D printing respirator, which uses one-sixth surgical mask as the filter membrane. X6 RESPIRATORS has a certain resistance to breathing. It is only suitable for people with normal cardiopulmonary function for a short period of time. Do not use it if you feel unwell after wearing it.
