Normal HEPA filters are great for removing particles but don't remove or destroy chemicals or odors that are in vapor phase. Today the best most common technology to use to remove these chemicals and odors in air involves using activated carbon, which often don't last the life of the filter and/or lose effectiveness in a few weeks. We are interested in novel technologies that can remove these odors, chemicals and volatile organic compounds (VOCs) from the air. It would also be advantageous if the technology eliminates or inactivates bacteria, virus, molds and other pathogens.
