Maintenance
The air cleaner media will normally need to be replaced every 4 to 6 months (end of the heating or cooling season) with normal usage. If an air cleaner condition indicator is used, change the media when the device indicates that service is required. Additionally, the frequency of filter replacement can be determined by visual examination.
