The application of ozone needs to be valuable in combination with the urgent needs of the market and the provision of practical results. In an economical hotel where the room is relatively closed and the occupancy rate is high, the treatment of the smell of the room and the smell of the room is particularly troublesome. Simply using the scenting agent is just a cover, which causes greater harm to the consumer. The air purifier that is physically filtered can only absorb dust and cannot effectively remove odor. At the same time, the long processing time is not suitable for the hotel where high-efficiency treatment is required, and the air deodorization method that needs fast and no secondary pollution is non-ozone. Using the strong oxidizing properties of ozone, disinfecting the air while removing smoke and odor is also a beneficial result of preventing cross-infection of passengers. At the same time, there is no need to open the window for ventilation, so the use of ozone will be a scientific choice for fast, healthy and environmental protection.
