WEARABLE AIR PURIFIER

A wearable air purification system including a wearable support for on or around a head region of a user; and an air delivery mask connected to the wearable support which is shaped to bound an air delivery region and to deliver a flow of air to the air delivery region. The air delivery mask includes an illumination source located along a longitudinal edge of the air delivery mask, and a control system that is configured to control the illumination source to convey information to a user in response to data received by the control system. The system is configured to direct light to the area occupied by the user's mouth when the air purifier is worn. The form of illumination means that the user's face is more visible to others which reduces facial features being obscured. The control system enables the product to be interactive for the user, delivering status information, and other data to enhance the user experience.
