In today's era, many factories need to use ion fans. But the human body will also be in an ionic wind environment, so there is no harm to the human body.
In fact, the regular ion fan has no harm to the human body. From its principle, it can be positively and negatively charged by the high-voltage ionized air molecules, and then blown out by the fan. This positive and negative charge will encounter the opposite charges. And, blowing to the human body is the same effect; if the surface of the human body has no positive or negative charge, the ions may adhere to the surface of the human body, so that the human body also carries a certain amount of 
charge, but the human body always touches the ground, and the electric charge is hard to accumulate in the The surface of the human body will flow to the earth; if the ion fan only blows a kind of electric charge, the human body is insulated from the ground. In this case, it is necessary to wear an anti-static clothing, otherwise the amount of charge accumulated in the human body is too large, once contacted with uncharged or oppositely charged Objects, there will be a large current, the human body will be subjected to electric shock, and serious conditions may cause heart failure.
Therefore, the irregular ion wind opportunity has a large safety production hazard, and the human body must be prepared for anti-static. However, under normal circumstances, the AC-type ion fan will not have much influence on the human body, and the human body will be guided away in time. Electrostatic charge is also the safest way.
