Negative Ion
Ions are electrically charged invisible particles. Cations are ions with a positive charge, anions are ions with a negative charge. Generally, there are a lot of cations in polluted air and anions are largely distributed in forests, beaches, and valleys where the air is free-flowing. In addition, a weak person will develop chronic diseases and preexisting diseases will worsen in air that is rich in cations. On the contrary, if there are a lot of anions, cells are activated and the resistance to diseases increases and the body becomes mildly alkaline and healthy.

Net Weight of negative ions
- To purify the air, the negative ions have a negative charge. When the negative ions meet the dust and other particles in the air, the positive and negative phases gather, thereby condensing the dust and other substances into a mass, increasing the weight of the dust, and making it land on the ground.
- Negative ions can destroy the cell membrane of bacteria to achieve the purpose of antibacterial and sterilization. In a high concentration of negative ion environment, the number of mold and bacteria in the air can be reduced by more than 90%.
- Insufficient sleep can cause a variety of diseases and seriously affect your health. Negative ions exist in nature as a kind of energy. Multiple exposure to negative ions can improve the quality of sleep and also relieve headaches, so that the mind is more sober.
