Negative ions in negative ion air purifiers can combine with tiny particles in the air, causing them to settle and purify the air; Meanwhile, negative ions also have certain benefits for human health. Zero noise, low energy consumption: no fan design, no noise generated during operation, and low energy consumption. Due to the complexity of technology, the price of negative ion air purifiers is usually higher.

A household air purifier is an electrical device that can remove or reduce pollutants in indoor air, such as dust, smoke, pollen, bacteria, viruses, odors, and harmful gases, thereby improving indoor air quality. It usually purifies the air through various technical means such as filters, electrostatic precipitators, and negative ion generators, allowing family members to breathe in cleaner air.
