A FILTER DETECTION BASED AIR PURIFICATION SYSTEM

摘要

A filter detection based air purification system for indicating the status of the filters is disclosed that includes a microprocessor configured to determine a status of a composite filter by monitoring a power consumption of the system and thereby comparing the power consumption with predefined values and reference values to revel the performance status of the system. The filter detection based air purification system operates in at least four modes of operation including a self check mode, a second calibration mode, a third normal mode, and a reset mode of operation that are indicated by predefined indicators positioned on a control panel. The indicators indicate to take appropriate actions to improve the system performance related to the conditions of the filters.
