Abstract: The article analyzes masks with technological phenomenology， reveals the difficulty of the mask-specific trust， and explains the “anti-wearing mask” phenomenon. The existing technological phenomenological theories have certain limitations in explaining mask cases， and there is a misuse of “embodied” concepts in Ihde's theory. “Magnification/reduction” and “transparency” concepts also have limitations. Compared with “transparency”， “security” is more important in mask cases. By examining the multistability of masks in different contexts， it is found that cultural and other contextual factors enter perception through the transmission of hermeneutic strategies and relationship strategies. As a philosophical research of specific technologies， the article can enrich the understanding of masks， and provide several revisions and supplements to Ihde's theory.
