Abstract: The widespread use of disposable masks during the COVID-19 pandemic has led to a sharp increase in plastic waste, mainly due to the non-biodegradable polypropylene materials used in conventional mask production. This study aimed to develop an eco-friendly Korean filter-certified health mask using biodegradable polylactic acid fibers and natural materials. The traditional synthetic components of the outer, filter, and inner layers of the mask were replaced with sustainable alternatives. In addition, antibacterial and deodorizing properties were enhanced using jade-based coatings. Performance tests confirmed the filtration efficiency and breathability of the mask. The mask achieved over 70% biodegradability and decomposed within 45 days in composting environments, leading to a lower environmental impact than conventional masks. In addition, wearability assessments indicated significantly improved comfort, particularly in terms of breathability and hygiene. This study highlights the potential of sustainable mask production and its role in addressing plastic waste. This study presents a sustainable alternative to maximize the biodegradability of mask materials, thereby reducing carbon emissions and landfill burdens after disposal. This work reflects the social responsibility towards environmental issues through the use of eco-friendly materials and has implications for increasing the demand for sustainable products.
