This filter should be replaced at least once every twelve months. If this filter remains in use longer than twelve months, it may begin to restrict airflow. In addition, certain conditions in your home will significantly add particles to the air, causing the filter to capture more particles than usual. This may shorten the filter life to less than twelve months, and reduce the effectiveness of the filter to capture particles. These conditions include: Dirty Ductwork, Construction Work, Sanding Projects, Pets, Burning Candles, Tobacco Smoke and Fireplace/Wood-Burning Stove Smoke. In addition, running your furnace or air conditioning fan continuously will help clean the air in your home, but could further shorten the life of the filter. So, if you use a furnace filter under these conditions, it could begin to restrict airflow, especially in energy efficient furnace and air conditioning systems. In these cases, it is recommended that you change the filter more frequently.
