    Abstract: An air purifying system includes a housing receiving at least partially therein a filter, a weighing system at least selectively connected to the filter, and an actuating system adapted to move the filter between a first position relative to the housing and a second position relative to the housing. A controller is configured to calibrate the weighting system when the filter is in the first position, and determine a weight of the filter when the weighting system is in the second position. A method for weighting in-situ a filter in an air purifying system is also presented.
