Ultra-Mini Air Supply
It substantially reduces pollutants, dust, smoke, pollens, germs, and odors in the air, so fresh air is released towards your mouth, nose and eyes. This laboratory tested ionic wind technology projects trillions of air cleansing ions from its grill that electronically charge pollutants, resulting in cleaner, fresher air while traveling. No filters to change or maintain. Has a patented solid platinum emitter and gold electroplated collector grid that give it the most powerful output of any wearable air purifier. Takes one CR123 lithium battery (included). (2½ x 1½ x ¾"; 1½ oz) Made in USA!
