In 2019, as the COVID-19 pandemic spread, most electronic mask products were bulky and failed to harmonize with fashion. To address this, we designed the LG PuriCare Wearable Air Purifier mask and its case to achieve both functionality and aesthetic harmony. The mask blends naturally with the face through smooth curves and refined fabric textures, while the case integrates UV sterilization, charging, and storage functions, expressing a balanced connection between technology and lifestyle.
