Negative ions are a kind of environment that uses the negative ions generated by itself to purify, remove dust and sterilize the air. Electric appliances are optimized to actively attack and capture harmful substances in the air.
What is negative ion?
Negative ions refer to ions with one or more negative charges. Air negative ions can be divided into three categories according to their mobility: large, medium and small. The ion mobility is greater than 0.4cm ⊃ 2/ (V ` s) is a large ion, less than 0.04cm ⊃ 2/ (V ` s) is a large ion, and the intermediate ion is a medium ion. These negative ions have a very high velocity of movement, collide with each other and gather in the air to form large ions or medium ions.
