When was the last time you changed the furnace filter?

It’s not something that’s at the top of most homeowners’ minds, but it’s extremely important for your health and the well-being of your furnace. Regularly changing the filter helps improve indoor air quality and keeps your heating system operating at peak efficiency.

Furnace filters trap dirt, dust and allergens that are in your home. This prevents them from recirculating, helping to alleviate breathing issues. Filters also help keep debris out of the heating system, preventing damage to the delicate internal mechanisms.

Over time, furnace filters fill up and need to be washed or replaced. Using a furnace with a clogged filter can redistribute allergens back into the air and can also cause strain to the furnace. Continuing to run the furnace with a full filter can significantly decrease indoor air quality and can even lead to a full-system breakdown.

To keep your air healthy and clean, and help your heating system run efficiently, keep these furnace filter tips in mind:

• Different filters are rated to last varying amounts of time, but we always recommend checking the filter monthly and replacing (or cleaning) as needed.
• Always turn off the furnace before replacing the filter.
• All filters will have an arrow indicating airflow. Make sure the arrow is facing the furnace and away from the return duct.

Even though checking and changing the air filter only takes a few minutes, many homeowners overlook this important task. For the sake of your indoor air quality and longevity of your heating system—take a few minutes to check and replace the filter.
