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.

The CADR value of an air purifier is an important indicator for measuring its purification efficiency, including particulate matter CADR, formaldehyde CADR, etc. The higher the value, the stronger the purification ability. Choose a suitable air purifier based on the actual usage area of the household to ensure that the purification effect covers the entire space. Understand the filter types and replacement cycles of air purifiers, and choose filters that are easy to purchase and cost-effective. Additional features such as intelligent control, sleep mode, and child lock can be selected according to individual needs.
