Abstract
An air purifying device includes an air purifier mechanism, a controller, and a sensing device configured to detect one or more conditions in a predetermined area proximate the air purifying device. The controller is configured to receive an input to select one of the predetermined operational settings to govern the operation of the air purifier mechanism. The air purifier mechanism is configured to operate in at least one of a plurality of modes of operation in each of its predetermined operational setting. The controller is configured to change modes of operation of the air purifier mechanism from a first mode of operation to a second mode of operation in response to its sensing device detecting a change in said one or more conditions in the predetermined area and based on the selected predetermined operational setting.
