Pandemics of microorganism are serious problem such as corona virus induced disease 2019(COVID-19), and the infectious diseases rapidly transmitted via airborne or aerosol among community space. To prevent aerosol infections, ozone and chlorine dioxide gases are practical methods in room air. However, ozone requires relatively high concentrations for this purpose, which might be toxic to humans present in the room. On the other hand, the low concentration of chlorine dioxide gas and aqueous solution are sufficiently effective against aerosol infection for the causative microorganism, and it is expected that when it is used in combination with a high-efficiency particulate air filter, it will be highly safe with high prevention effect and cost effectiveness.
微生物大流行是严重问题，如2019年冠状病毒病（COVID-19），以及在社区空间中通过空气传播或气溶胶迅速传播的传染病。为防止气溶胶感染，臭氧和二氧化氯气体是室内空气消毒的实用方法。然而，为此目的臭氧需要相对较高的浓度，这可能对室内人员有毒。另一方面，低浓度的二氧化氯气体和水溶液对引起感染的微生物气溶胶感染具有足够的效果，并且预计当它与高效空气过滤器结合使用时，将具有高度安全性、高预防效果和成本效益。
