Abstract
A filter recognition system for use with an air purifier is provided. The air filter assembly or filter clip includes identification pins/taps which are read by the air purifier to determine the filter type. The filter recognition system adjusts the motor parameter based on the filter type. Additionally, the filter recognition system adjusts the filter timer to automatically communicate to a user the recommended time to change the filter based on the identified filter type.
