The Aura Air Mini supplies an effective buffer between you and the dangerous air particles around you. Breathing is not a choice - but breathing clean air is. The pre-filter captures large particles, including dust, pollen, insects, animal hair and more. The ionizier creates the pure air, just like in nature, on the go. It releases positive and negative ions to freshen up the space around you, and removes any remaining harmful pollutants. The Aura Air Mini's battery lasts 5-6 hours. Recharging is easy: just use the USB-C cable supplied with the original package.
