Description: A smart mask is a wearable device that can monitor air quality and provide feedback on respiratory health. This type of technology combines advanced sensors and connectivity to offer real-time data on air pollution, particulate levels, and other contaminants. Smart masks often come equipped with replaceable filters, allowing for effective protection against harmful particles. Additionally, many of these masks connect to mobile applications, where users can visualize statistics about air quality and receive personalized recommendations to improve their respiratory health. The integration of technology in these devices not only aims to protect the user but also to educate them about their environment, fostering greater awareness of the air quality they breathe. With the rise of urbanization and concerns about pollution, smart masks have become increasingly relevant, turning into an essential tool for individuals living in areas with high pollution levels or for those with pre-existing respiratory conditions.
