In addition, as a prior art for sterilizing and removing bacteria, viruses, and fungi by generating OH radicals, Korean Utility Model Registration No. 20-0422046 (OH radical sterilizer) has been proposed.

This prior art oxidatively decomposes and removes all biological contaminants and pathogens such as bacteria, viruses, and fungi on air and surfaces (objects, human body), and then sterilizes them. provides an effect.

However, the prior art presented in the prior art is a technology for sterilizing and removing harmful substances and various viruses or molds contained in the air using OH radicals while inhaling and discharging indoor air. Therefore, there is a problem that the sterilization range is locally limited to the installed location.

In addition, the prior art presented in the prior art has problems in that it is difficult to transport and move the "OH radical sterilizer" depending on the location or conditions of the indoor space, and it is not possible to sterilize the indoor air as a whole.
