Air+ Smart Mask (world's first) reduces humidity in masks by 40%, drops temperature by up to 4 °C, and CO₂ levels from 5% to 1.5%. This level of comfort was only available in bulky and complex industrial masks – now made possible for consumers in a compact, convenient, hygienic system for daily use, and with socially acceptable esthetics. This reduces stuffiness, headaches and shortness of breath from the build-up of CO₂ and heat and increases users' willingness to wear protection. The masks achieve NIOSH and CE certification for N95 filtration and facial seal and overcome the challenge of ergonomic fit-testing for children as young as seven.
