When purchasing the ozone disinfection machine for farm, determine its use purpose, which is used for air sterilization deodorization or water treatment. When used for air treatment, low-concentration and economical ozone disinfection machine can be selected, including open-air sterilizers. For sterilization equipment used in farms, it is recommended to choose an air-source model. The high-concentration ozone disinfection machine is equipped with gas source, gas source treatment device and ozone generator as standard. The small size can be designed as an integrated model with an output of 5-200g/h. Large and medium-sized ozone disinfection machines basically exist in the form of units.

　　The quality of ozone disinfection machine can be distinguished from manufacturing materials, system configuration, cooling method, working frequency, control method, ozone concentration, gas source and electric energy consumption indicators. The ozone disinfection machine should be manufactured with high dielectric materials, standard configuration (including gas source and purification device), dual electrode cooling, high frequency drive, intelligent control, high ozone concentration output, low power consumption and low gas source consumption.

　　Understand the structure of the ozone disinfection machine, whether it can run continuously, ozone output concentration and other indicators. Whether there is a gas source, the price of the generator with the gas source and the generator without the gas source are very different. Confirm the rated output of the ozone sterilizer, whether the output is marked with the air source or the oxygen source. Because the ozone output of ozone disinfection machine using oxygen source is twice as large as that using air source, the cost difference between the two is nearly double.

　　 The design, configuration and manufacturing materials of the ozone disinfection machine for farm are all carried out according to their standards, and the cost is much higher than the low-grade generator and low-configuration generator. However, the performance of the ozone disinfection machine is very stable, and the ozone concentration and output are not affected by environmental factors. While the low-configuration ozone sterilizer is greatly affected by the environment during operation, the increase in temperature and humidity can greatly reduce the ozone output and concentration, affecting the treatment effect. When buying, the price and performance should be comprehensively evaluated.
