A recently filed patent (Publication Number: US20230266027A1) describes an air purifier with advanced features for efficient carbon dioxide (CO2) removal. The air purifier consists of a body with an air inlet and a clean air outlet. It includes two CO2 sensors, one at the air inlet and another at the clean air outlet. The device also features a CO2 adsorption unit that chemically adsorbs carbon dioxide using a basic solution. A pump delivers ambient air to the CO2 adsorption unit through the air inlet, while a base tank supplies the basic solution. The air, after CO2 adsorption, is treated with an acidic solution in an acid tank. An electrodialysis unit separates the salt components formed during the treatment process into acid and base.

The patent also mentions various sensors integrated into the air purifier for enhanced functionality. One sensor, located in the CO2 adsorption unit, measures pH, turbidity, and vibration values. Another sensor, connected to the pump, measures the air flow. Two additional sensors, one in the acid tank and the other in the base tank, monitor liquid levels or pH values of the solutions in the tanks. Furthermore, a sensor in the electrodialysis unit measures the current value.

To ensure optimal performance and user safety, the air purifier includes a control unit that receives data from all the sensors in a specific order. This control unit compares the received data with predetermined operational data, set by the manufacturer and the individual components (CO2 adsorption unit, pump, base tank, acid tank, and electrodialysis unit) under normal conditions. By analyzing this data, the control unit can detect any errors or deviations from the expected values and promptly alert the user.

Overall, this patent describes an air purifier with a comprehensive CO2 removal system and advanced sensor technology. The inclusion of multiple sensors and a control unit allows for efficient monitoring and error detection, ensuring optimal performance and user safety.
