Vystar Corp. announced that new and improved RxAir® UV Light Air Purifiers are now available to combat cold, flu and other airborne germs that are more pervasive during the winter. Vystar acquired RxAir approximately nine months ago and immediately began upgrading the air purifiers to improve performance and longevity. The first upgraded RxAir units are now available for purchase via RxAir.com, Rotmans.com, Rotmans Furniture & Carpet in Worcester, Mass., and RxAir medical distributors. New units now available feature a higher grade UV light bulb that lasts longer and produces longer UV wave length for more efficient killing/inactivation of bacteria, germs and other pathogens. The new units also offer improved alert codes to more easily identify when action, such as replacing a bulb cartridge, is needed.
