The negative ion function is enabled by default. The purifier can generate
negative ions when it is working, and then the negative air ions (NAI) are
produced through the reaction between the negative electron and the oxygen
molecules. NAI is very good at trapping certain air pollutants.
The function can be enabled or disabled in the app. When it is enabled, the
negative ion indicator is on; when it is disabled, the indicator is off.
