The project is developing a novel air purifier capable of removing pollutants such as volatile organic compounds (VOCs) and bio-contaminants in the aircraft cabin zone. The device will be installed after the HEPA filtration stage of the recirculated air and will provide efficient and durable degradation of ozone, VOCs and bio-contaminants. The technology implemented combine adsorption and photocatalysis to obtain an air purification media with high removal capabilities, low generation of by-products and high durability of the filter. The experiments conducted have allowed to select the best geometry of the air purifier and to select several air purification medias (composite media or combination of medias) presenting high VOC removal at simulated aircraft conditions.
