General description This negative ion purifier effectively releases negative ions into the air, which helps to purify the air by causing positively charged ions to aggregate and lose their ability to float freely. This process improves mood and health, allowing you to enjoy fresh air at home. The portable ionizer uses anion technology to refresh indoor air naturally without filters, effectively eliminating pet odors and other unpleasant smells. For optimal results, it is recommended to use at least one unit in each bedroom, bathroom, dining room, living room, and kitchen.
