I have never used Maurer negative ion generator, and I can only give suggestions on the selection criteria of negative ion generator. At present, the reputation of negative ions in China is relatively good, and Sailumei is the best. From the website of Celumi, we can know that the correct selection criteria of negative ion products need to meet at least the following points (which can also be judged as considerable according to common sense):

1, does not generate static electricity and positive ions, and does not attack people nearby (especially children at home).

2, can be used for a long time, long-term use without dizziness (high radiation will make you dizzy)

3, ozone can not be produced, ozone can only be used for disinfection of utensils (disinfection of cupboards), and can not directly affect the human body.

It is usually claimed that tens of millions of people should pay special attention. High voltage and multiple emitters will form very large radiation and electric fields (beaters), which will affect the stability of negative ions.

I have also seen the experiment of blowing negative ions on the human body, charging the human body and introducing it into the ashtray through wires to eliminate smoke. It is said that it acts on the human body, but it actually brings high pressure to the human body and is harmful to the human body.

According to the above standards, you can judge whether it is a good negative ion product. As long as these standards are met, there will be good results. Negative ions are very popular now. Usually when the market is on fire, it will be mixed. Everyone should choose carefully.
