Abstract

A method for determining a filter selection for an air filtration system having a current air filter includes entering filtration system information into a processor having access to pressure drop versus dust holding capacity curves for a plurality of different air filters, wherein the filtration system information includes user experience information including volume of air processed with the current air filter in the air filtration system and pressure drop with the current air filter after processing the volume of air; determining a cost factor of operating the air filtration system with the current filter for processing the volume of air; determining a theoretical quantity of dust held by the current filter at the pressure drop using a pressure drop versus dust holding capacity curve for the current air filter and the pressure drop exhibited by the current air filter after processing the volume of air; selecting a proposed air filter from the plurality of different air filters and different from the current air filter; determining an estimated volume of air that can be processed with the proposed air filter to reach the pressure drop, this determining step being conducted using the theoretical quantity of dust and a pressure drop versus dust holding capacity curve for the proposed air filter; determining an estimated cost factor of operating the air filtration system with the proposed filter for processing the volume of air; and presenting a comparison of the cost factor and the estimated cost factor on a display communicated with the processor.
