Our gas treatment is extremely efficient and effective in the elimination of virtually any odour, volatile compound (VOC’s), bacteria, and guarantees 99.9% efficacy in the eradication of viruses including the SARS-CoV-2 virus which causes the disease known as COVID-19. In layman’s terms, our gases consist of high concentrations of Hydrogen Peroxide (H2O2), Purified Ozone (O3), and Hydroxyl Radicals (*HO). This decontamination method is called Multiphase Photocatalytic Oxidation (MPO), also known as Photocatalysis. These oxidative gases react and break down the organic compounds into simple and safe elements, destroying virus and bacteria. The PurAyr process is designed to treat odours, bacteria, virus and VOC’s without the use of harmful chemicals. There are no byproducts or residue remaining on the surface of all treated items
