A method, an air treatment device and a system associated with determining a degree of utilized capacity of a filter for processing air present in an ambient volume. Determining a total accumulated pollutant amount in the filter. Comparing the determined total accumulated pollutant amount to a reference pollutant amount to determine the degree of utilized capacity. The reference pollutant amount is a pollutant amount present in the filter when the air treatment device produces a predetermined clean air flow. The accumulated pollutant amount in the filter is determined based on data obtained from a sensor arranged to measure a current pollutant concentration in the ambient volume and/or pollutant concentration data indicative of a current pollutant concentration in the ambient volume and an estimated volume of air processed by the air treatment device. The volume is estimated based on a current air flow through the filter.

A filter assembly includes a support fame, a filter media, and a conditioning device. The filter media is coupled to the support frame. The filter media has a dirty side that receives an air stream and a clean side that outputs the air stream after having been filtered by the filter media. The conditioning device is coupled to the support frame. The conditioning device is positioned downstream of the clean side of the filter media with respect to the air stream and directly contacts the clean side of the filter media.
