The PRO-Cell is air+health’s patent-pending technology to eliminate hazardous chemicals, gases, and odors. Our PRO-Cell filters have a Titanium Dioxide (TiO2) layer that when exposed to the powerful germicidal ultraviolet (UVC) light, it creates a reaction, VOCs, gaseous contaminants, and odors come into contact with the PRO-Cell™ surface. These harmful chemicals are converted to odorless, harmless water vapor and Carbon Dioxide. The HEPA filter captures particles, the PRO-Cell eliminates chemicals, and the UVC reduces biological contaminants such as bacteria, viruses, mold, and fungi. When used properly, the PRO-Cell technology is a powerful air purifier ideal for improving air quality.
