System and method of cleaning fluid, and vehicle connected to the system

A method of cleaning an airflow with an air filter, the method comprising:

• providing the airflow through the air filter;
• by an airflow control device, controlling the airflow through the air filter;
• by a controlling circuit, controlling the airflow control device in accordance with a pre-determined average loading rate of the air filter;
• by an electronic processing circuit, determining a filter usage value of the air filter and storing the filter usage value to a historical data in a memory;
• and
• by a microprocessor, generating, based on the historical data, an adjusted average loading rate of the air filter for the controlling circuit to control the airflow control device,
• wherein the adjusted average loading rate of the air filter is different from the pre-determined average loading rate of the air filter,
• wherein the adjusted average loading rate of the air filter reduces or increases a current average loading rate of the air filter such that a pre-determined filter load is achieved within a pre-determined tolerance of a pre-determined next maintenance time;
• wherein the electronic processing circuit further determines an end-of-life time of the air filter based on the historical data and compares the end-of-life time to the pre-determined next maintenance time;
• and
• wherein the electronic processing circuit further determines, based on the historical data, a reduction in the average loading rate of the air filter when the end-of-life time is before the pre-determined next maintenance time, or alternatively, determines, based on the historical data, an increase in the average loading rate of the air filter when the end-of-life time is after the pre-determined next maintenance time, such that the end-of-life time occurs within the pre-determined tolerance of the pre-determined next maintenance time.

An air filter system comprising:

• an air filter;
• an air channel in fluid communication with the air filter and comprising an intake and an outlet;
• a receptacle configured to receive the air filter in an airflow when air is flowing through the air channel;
• an airflow control device operable for controlling the airflow through the air filter within the receptacle;
• a controlling circuit for controlling the airflow control device in accordance with a pre-determined average loading rate of the air filter;
• and
• an electronic processing circuit configured to:
• determine a filter usage value of the air filter and store the filter usage value to a historical data in a memory;
• and
• by a microprocessor and based on the historical data, generate an adjusted average loading rate of the air filter for the controlling circuit to control the airflow control device,
• wherein the adjusted average loading rate of the air filter reduces or increases a current average loading rate of the air filter such that a pre-determined filter load is achieved within a pre-determined tolerance of a pre-determined next maintenance time, and
• wherein the electronic processing circuit is operably coupled to a user interface including a display for displaying a current filter load and an input to enable a user, based on the current filter load, to adjust the current average loading rate of the air filter.
