The principle of negative ion generation
negative ions will be released into the air molecules, and the unclean particles attached to the air will be negatively charged. Other air molecules are positively charged and attract negatively charged molecules and particles. Molecules and particles with positive and negative charges form particulate matter, which sinks into the ground by gravity, thereby preventing harmful gases from entering the human respiratory system.
