How to choose:
Air pollution pollutants are:
Smoke and dust, total suspended particulate matter, inhalable particulate matter (PM 10), fine particulate matter (PM2.5),
Nitrogen dioxide, sulfur dioxide, carbon monoxide, ozone, volatile organic compounds, etc.
Among all pollutants, fine particulate matter pm2.5 is the most harmful, because it can enter the lungs, and the harm is almost irreversible.
Therefore, the negative ion generator Senpeptidyl, which can eliminate pm2.5, should be selected. Because the released negative ions are attached to the ups and downs in the air, they are combined and sink to the ground, so the smaller the ups and downs, the better the effect of negative ions.
It should release negative ions with smaller particle size, because medical research shows that only negative ions with smaller particle size can easily enter the human body and play a role in biological health care. At present, there are two patented technologies, negative ion converter technology and nano-fullerene negative ion releaser technology, which can realize the generation of small particle size negative ions. However, the negative ions with small particle size have long migration distance and high activity, which can radiate to a larger range indoors and truly realize their efficacy. If the negative ion concentration detector can only have high concentration negative ions near the emission port, it is not recommended to buy it.
And pay attention to whether derivatives such as ozone and positive ions are produced at the same time when negative ions are produced. Ozone should be released and used independently.
