Meet the Air Ring: a wearable air purifier that brings you clean air anywhere. It relies on N95 HEPA filters, UV-C LED with Photo-Catalytic TiO2, & Carbon filtration to get the job done. It lasts up to 8 hours on a single battery. You can power it with a USB power bank.
The Air Ring works as a face mask and shield for indoor spaces. It can also be used in sealed mask mode when threat levels are higher.
