With the development of industrialization and urbanization, demand for quality air gains upward momentum every step of the way. Despite blocking allergens and pollutants, respiration protection aims highly at getting rid of smelly and harmful odors. Healthnaso Plus® — the odor-repellent nasal mask is equipped with a biocompatible carrier and an embedded filter. The biomedical-grade material and the in-the-nose design provide wearers with nearly senseless feel and almost invisible appearance. In the attempt to block the entry of allergens and pollutants as well as to release forest-level negative ions, the exceptional filter was co-developed with a Japanese firm. The negative ions discharged would neutralize tiny particulates and bad odor particles to refresh a person’s body and mind.
