Recommended Replacement:
This filter should be replaced at least once every twelve months. The life of a filter can depend on the individual conditions in your home. You may need to change your filter more often if your home has construction work in progress or very polluted indoor air. Also, running your HVAC fan continuously will improve your air quality but will shorten the life of the filter.
