It depends on whether the steamer has a built-in negative ion generator. Only the built-in negative ion generator can produce negative ions and the quality of the negative ion generator. If the built-in negative ion generator is inferior and poor in quality, it is easy to be damaged and cannot generate negative ions. Because high voltage is needed when negative ions are generated, many manufacturers in the market use inferior generators filled with inferior resins in order to reduce costs. Under the action of high pressure, it is easy to be broken down, and ordinary carbon fiber is used as the release tip. Ordinary carbon fiber materials have high resistance, so when negative ions are released by electricity, they will produce ozone, positive ions and other derivatives, which will have a certain impact on people's health for a long time. As follows:

Only a professional negative ion generator filled with twisted resin or a generator with piezoelectric ceramic negative ion chip technology can avoid the breakdown problem, and fullerene, a noisy electrocatalyst material, can avoid the generation of derivatives such as ozone and positive ions, and its service life can be as high as 200,000 hours. If it is combined with the ecological negative ion chip technology, it can produce ecological small-particle negative ions equivalent to nature, which can easily penetrate the blood-brain barrier of human body. As follows:
