Any unsuffocating mask available? Is it truly healthy when wearing suffocating masks? When the filtration efficiency became a norm for “mask”, Healthnaso® tried to get back to the very beginning and figured out why respiratory illnesses grew into a major issue for us humans. Hardly seen polluting particles and nearly hurt senseless lung cause a great deal of preventable regrets. The standardization of masks is for healthier breathing, not towards the limits of filtration efficiency. Is it a viable option if the inhaling air is significantly blocked and the breathing comfort is tremendously overlooked? From the study of nose anatomy, the application of state-of-the-art biomedical materials, to the verification of scientific experiments, the health-centric invisible nose mask was ultimately created.
