The air cleaner media in the Model 5000 can last from 6 months up to 2 years. If installed on a 5-ton system, in the presence of high concentration of particulate, or if the furnace fan is on continuously, it may be necessary to change the media more frequently. In any application, the life of the media is dependant upon the total volume of air being moved through it as well as the amount of particulate it is filtering.
