The mask cleanses the air that you have to breathe in a crowded subway or on sale in a store. To do this, the mask was equipped with a high-tech filter to remove pollutants.
The device is powered by a battery, which has enough charge for 5 hours of continuous fresh breathing. The device drives 240 liters of air per minute through four different filters. And creates an air pocket in front of a person's face.ðŸŽ
