Packaging Design Mist Humidifier by Xiaochen Wang As a product designer, it is very necessary to think about "product packaging" in the whole product system. Therefore, the packaging of this humidifier itself is a part of the product. If the "packaging" is discarded, the humidifier will not work properly, which conveys the designer's goodwill for environmental protection. Unlike other humidifiers, which control the amount of fog by electronic principle, this humidifier controls the amount of fog by pulling the trigger.
