How do negative ions purify the air?


1) Ionizing

When the air ionizer charges oxygen in the air, negative ions are generated.


2) Capturing & Neutralizing

Negative ions attract & bind with airborne pollutants such as dust, pollen, smoke, and PM2.5, Charge neutralization occurs. 


3) Landing

The air pollutants get clustered and subside naturally to the ground instead of being inhaled into the lungs.
