A processing system including at least one processor may obtain utilization data of an air filter in an air filtration system and environmental data for at least one location associated with the air filtration system. The processing system may then determine at least one filter changing action based upon at least the utilization data and the environmental data and transmit at least one instruction to implement the at least one filter changing action.

A system (10) for treating the air in the cabin of a vehicle includes a casing, an air conditioning apparatus, a filtering device (16) an RFID tag (28) containing identification information about the filtering device (16). An RFID reader (30) co-operates with the RFID tag (28) to read the identification information. A control unit (32) is connected to the RFID reader (30) and configured for receiving the identification information and for executing predefined operations as a function of the identification information.

A method of alerting about cleaning of an air purifier includes an air purifier operating step of operating an air condition installed inside a vehicle and inputting an operational signal of the air purifier into a control unit, a sensor value inputting step of inputting information (e.g., necessary) to alert about a time for cleaning the air purifier into the control unit from sensors installed, a purification efficiency computing step of computing the purification efficiency of the air purifier, a purification efficiency comparing step of determining whether or not the purification efficiency of the air purifier is equal to or lower than reference efficiency, and a cleaning time alerting step of alerting that it is time to clean the air purifier, when the purification efficiency of the air purifier is (e.g., substantially) equal to or lower than the reference efficiency.

A method of preventing air pollution in a vehicle is disclosed. Firstly, an out-car gas detection device, an in-car gas detection device and a purification device are provided to detect the air pollution and transmit a respective gas detection datum to a connection device. An in-car gas exchange system is provided for intelligently selecting and controlling a gas outside the vehicle to be introduced or not introduced into the inner space of the vehicle. The connection device receives and compares the gas detection data, so that the connection device selectively transmits a control instruction to the in-car gas exchange system and the purification device, and the air pollution in the inner space of the vehicle is exchanged and filtered, so as to provide clean, safe and breathable air.

A direct air capture system for capturing, containing, and transporting airborne matter includes a filter assembly, a particle container configured to receive airborne matter loosened from the filter assembly, a means for cowling venting configured to utilize vacuum pressure to transport the airborne matter. The system also includes an electric motor assembly having a motor drive, a drive gear, and a drive shaft, as well as at least one scrubbing brush configured to loosen airborne matter from the filter assembly.

A filter device of an air-conditioning system of a motor vehicle is provided. The filter device has at least one indicator device arranged in the filter device, the indicator device having at least one electrically conductive indicator material, the conductive characteristics of which vary in a manner dependent on the degree of loading of the filter device with filtered particles. Also provided is a motor vehicle having an air-conditioning system comprising the filter device, and a method for detecting the state of the filter device.

A system and method for measuring odor from an air conditioner of a vehicle which are able to accurately measure air conditioner odor that varies in each operation mode of the air conditioner. The system and method enable accurate measurement of air conditioner odor that varies in each of operating modes of air conditioner such as a blower-on step, an air conditioner-on step, and an air conditioner-off step, and enable accurate examination and measures for an air-conditioning system on the basis of the measured result.
