Filtrete filters should be replaced at least once every three months. If a Filtrete furnace filter remains in use longer than three 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 will shorten the filter life to less than three 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 Filtrete filter under these conditions, it could begin to restrict airflow, especially in energy efficient furnace and air conditioning systems. In these cases, change the filter more frequently.
