Integrated air purifier: Combining multiple purification technologies such as HEPA filters, activated carbon, negative ions, etc., it can comprehensively remove various pollutants from the air. Some products are equipped with intelligent monitoring systems and automatic adjustment functions, which can automatically adjust the working mode according to indoor air quality. Due to the integration of multiple purification technologies, the price of integrated air purifiers is usually higher. Multiple purification technologies require different maintenance methods, increasing the complexity of their use.

Physical air purifiers use high-efficiency filtering materials such as HEPA filters, which can effectively remove large and small particles such as dust, pollen, and bacteria from the air. The physical filtration method is mature and stable, and is not prone to secondary pollution. But the filter needs to be cleaned or replaced regularly, which increases the cost of use. Some products may produce significant noise during high-speed operation.
