Does the negative ion health instrument blow air conditioning?
There will be a slight negative ion wind when negative ions are ejected, but this can be basically ignored. Some people can feel it, and some people can't.

When you say blowing cold air, can you feel the wind obviously? If so, it is that the negative ion health instrument itself is equipped with a fan device. Due to technical limitations, the negative ions produced by this negative ion health instrument have large particle size and low activity, so it must be driven by a fan to reach a long distance. Without a fan, negative ions can only be detected around the machine 1 meter.

At present, only the negative ion health instrument running nano-fullerene negative ion releaser and ecological negative ion chip technology can form a real negative ion bath environment at 4-5 meters, independent of wind power. Due to the small particle size of negative ions produced by this negative ion health care instrument, it is easier to penetrate the blood-brain barrier of human body and play the therapeutic role of negative oxygen ions on insomnia, three highs, asthma, cancer and so on.
