The air filter in your furnace traps dust, dirt, and allergens to keep the air in your home clean. A clogged filter restricts airflow, making your furnace work harder, which reduces its efficiency and lifespan.
How to Do It:
1. Turn off the furnace before starting.
2. Locate the air filter, usually found in the return air duct or near the blower compartment.
3. Remove the old filter and inspect it. If it’s clogged with dirt and dust, it’s time for a replacement.
4. Insert a new filter, ensuring it fits securely and the arrows on the filter align with the airflow direction.
Replace your furnace filter every 1-3 months, depending on usage and air quality in your home.
