This technology introduces a hybrid air filter mask that significantly enhances filtration efficiency for particles ranging from 11.5 nm to 2.5 µm. It offers stable filtration efficiency of 94%–99% for key particle sizes and extends mask service life to 48 hours. The low pressure drop and 100% sterilization effect make it suitable for personal healthcare, face masks, and indoor air quality control. The technology is easily integrated into current manufacturing processes, targeting a global market for protective masks.
