Claim 0:
1. An air purifier system, comprising:
an air purifier filter having a filter type, wherein the air purifier filter is able to filter a plurality of different pollutants according to the filter type of the air purifier filter;
a machine readable identifier attached to the air purifier filter, the machine readable identifier storing type information identifying the filter type of the air purifier filter for removal of a target pollutant and storing a performance profile indicating performance of the air purifier filter, over a period of time, specific to the target pollutant to be filtered by the air purifier filter from the plurality of different pollutants that can be filtered by the air purifier filter based on the filter type, wherein the indication of the performance comprises a combination of a cumulative air flow and a cumulative amount of the target pollutant through the air purifier filter over the period of time, and further wherein, the indication of the performance is used in estimating a lifetime of the air purifier filter for the target pollutant;
a write circuit configured to update the performance profile stored on the machine readable identifier over the period of time as the air purifier filter removes the target pollutant; and
a controller configured to indicate to a user when to change the air purifier filter based on the type information and the performance profile provided by the machine readable identifier when the air purifier filter is used for filtering the target pollutant.
