Claim Text:
1. An HVAC system, comprising: an air cleaner; a fan configured to selectively generate an air flow, wherein at least a portion of the air flow is passed through the air cleaner; and a controller comprising a user interface and configured to receive an input of a threshold criterion value associated with the airflow generated by the fan via the user interface, determine a substantially current air flow related criterion value associated with the airflow generated by the fan, compare the air flow related criterion value to the threshold criterion value, and control operation of the air cleaner in response to the result of the comparison between the air flow related criterion value and the threshold criterion value, wherein the air cleaner is operated at a power level setting less than a maximum power setting of the air cleaner in response to the result of the comparison that the air flow related criterion value is less than the threshold criterion value.
