Modern air purifiers are often equipped with air quality monitoring sensors, which can monitor indoor air quality in real time and automatically adjust the working mode based on the monitoring results, achieving intelligent management. In order to meet the needs of household use, air purifiers are designed with a focus on low-noise operation, ensuring that they purify the air without disturbing the rest and work of family members.

The air purifier is equipped with multiple layers of filters, including primary filters, HEPA filters (high-efficiency air filters), activated carbon filters, etc., which can effectively intercept large and small particles, harmful gases, and odors in the air. Some high-end air purifiers are also equipped with ultraviolet sterilization lamps or photocatalyst technology, which can kill bacteria, viruses and other microorganisms in the air, further ensuring the safety of indoor air.
