Understanding Your Molekule Air Purifier
Photo Electrochemical Oxidation (PECO) Technology
Unlike traditional filters that merely capture pollutants, Molekule's patented PECO technology uses light-activated nanotechnology to destroy viruses, volatile organic compounds (VOCs), allergens, bacteria, and mold at a molecular level.
