The intake passage is connected to the gas-exchange processing device and has an intake opening for guiding the outdoor gas into an indoor space. The discharge passage is connected to the gas-exchange processing device and has a discharge opening for discharging the air pollution source to the outdoor space. The intelligent control-driving processing device controls the gas-exchange processing device to be enabled under a surveillance condition of the gas detection module, so that the air pollution source passes through the discharge passage, filtered and purified by a cleaning and filtration assembly, and is discharged to the outdoor space, thereby allowing the indoor space to have a clean air.

Data relating to the status of a vehicle, an internal combustion engine powering the vehicle, and various filtration systems that provide filtered fluid to the vehicle and/or internal combustion engine is generated or gathered by an engine control module and a filtration monitoring system. The engine control module and the filtration monitoring system provide the data to a telematics system for transmitting the data to a remote data center (e.g., a cloud computing system, a remote diagnostics system, a maintenance system, etc.). Depending on an availability of a cellular data connection, the data is either sent directly to the remote data center via a network, or indirectly by first transmitting the data over a local connection to an operator device (e.g., a smartphone), which then sends the data to the remote data center once a connection to the network is available.

A method of monitoring indoor environments for aerosolized pathogens includes: (a) receiving a pathogen status for each of a plurality of aerosol samples collected by a plurality of corresponding air treatment devices; (b) determining whether the pathogen status for each aerosol sample changes a safety status of a corresponding indoor environment from which the aerosol sample was collected; and (c) in response to determining a change in the safety status, generating a notification associated with the change in the safety status for the corresponding indoor environment.

A pollution monitoring system and a method is disclosed. The pollution monitoring system comprises an on-board sensor unit having a plurality of sensors, configured for monitoring air quality by measuring pollution data in the air and a power control unit connected with the on-board sensor unit for controlling the operation of the on-board sensor unit. The pollution monitoring system further comprises microcontroller configured for generating control signals to be transmitted to the power control unit for controlling operation of on-board sensor unit. The microcontroller is configured for receiving information from a base station regarding operation of the on-board sensor unit.

A method, an air treatment device and a system associated with determining a degree of utilized capacity of a filter for processing air present in an ambient volume. Determining a total accumulated pollutant amount in the filter. Comparing the determined total accumulated pollutant amount to a reference pollutant amount to determine the degree of utilized capacity. The reference pollutant amount is a pollutant amount present in the filter when the air treatment device produces a predetermined clean air flow. The accumulated pollutant amount in the filter is determined based on data obtained from a sensor arranged to measure a current pollutant concentration in the ambient volume and/or pollutant concentration data indicative of a current pollutant concentration in the ambient volume and an estimated volume of air processed by the air treatment device. The volume is estimated based on a current air flow through the filter.

An indoor pollution prevention system includes a plurality of gas detection modules, one or more intelligent control-driving processing devices, one or more gas-exchange processing devices, and one or more indoor cleaning and filtration devices. The gas-exchange processing device includes one or more flow-guiding component and a cleaning and filtration assembly. The intelligent control-driving processing device controls the operation of the indoor cleaning and filtration device in real-time under a surveillance condition, therefore the air pollution source in the indoor space passes through the indoor cleaning and filtration device, allowing the air pollution source in the indoor space to be filtered and exchanged to become a clean air.
