Claim:
1. A method for purifying air, comprising: passing air over a particle counter in communication with a control system; determining through the control system an initial level of air quality based on a particle count detected by the particle counter; designating a first sensitivity setting of a sensor in communication with the control system and further in communication with a fan, wherein the first sensitivity setting allows the fan to generate a first set of airflows; determining through the control system a second level of air quality based on a second particle count detected by the particle counter; if the second level of air quality deviates from the initial level of air quality by more than a specified amount, adjusting the first sensitivity setting of the sensor to a second sensitivity setting, thereby allowing the fan to generate a second set of airflows.
