Negative ions, also known as negatively charged gas ions floating in the air, how much do you know about these negatively charged gas ions? What are the effects of negative ions?

Air Purification

Negative ions carry a negative charge, so when they encounter particles like dust in the air, a reaction occurs. Due to the attraction between opposite charges, the dust particles are clumped together, becoming heavier, and consequently, they fall to the ground, achieving the effect of purifying the air.
