AI Technical Summary
Existing air purification filter devices suffer from insufficient accuracy and low efficiency in performance evaluation tests and routine maintenance. In particular, improper configuration of maintenance components for HEPA filters leads to the risk of viral and bacterial infection, and improper placement of the testing port affects the evaluation of purification performance.
It features a compact design with the intake and purification filter located on the front of the device, and the fan chamber and rear chamber separated. The detection port is located in the center of the purification filter and fan. Performance is evaluated and maintenance is performed on the front by connecting a detector. Airflow is optimized by incorporating a rectifier.
It improves the accuracy of performance evaluation of air purification filters and the efficiency of daily maintenance, reduces the risk of viral and bacterial infection, achieves compactness and efficient maintenance of the device, and reduces energy consumption and carbon emissions.
