In fact, you should replace your furnace filter every one to three months during the heating season, so here’s a step-by-step guide to help you with this task:

1. Open the access panel or remove it, depending on your model
2. Check near the cold air intake to locate the old filter
3. Slide out the old filter
4. Line up the new filter using the arrows on the frame
5. Slide the new filter into place
6. Replace or close the access panel
