For our new oven, it is recommended to change the filter every three months. However, a friend who is an HVAC specialist told me that replacing it monthly keeps the highly efficient furnace operating at optimum levels. He was right because the first time I waited three months and it was obviously dirty. By replacing it monthly, I found that while you can see the dust stuck in it, it's not that dirty. I also found that my dust is less around the house.
