Maintaining your furnace is essential for keeping it efficient and reliable, especially during the cold winter months. One of the most important yet often overlooked tasks is changing the furnace filter. This simple step improves indoor air quality, helps your furnace run more efficiently, reduces energy costs, and prevents costly repairs or premature system failure.
Furnace filters trap dust, pollen, pet dander, and other airborne particles. Over time, these filters become clogged, restricting airflow and forcing your furnace to work harder. That added strain increases energy consumption and causes unnecessary wear on the system’s components.
Understanding When to Change Your Furnace Filter
The frequency of furnace filter changes depends on the type of filter, the air quality in your home, and how often your furnace is used. Below are general guidelines to follow:
Standard 1-Inch Filters
Basic 1-inch filters typically need to be replaced every 30 days to 3 months. Homes with pets, indoor smokers, or high levels of dust and allergens may require more frequent replacement.
Pleated 4-Inch Filters
Thicker, pleated 4-inch filters can last longer, usually 6 months to 1 year. Their larger surface area captures more particles, making them more efficient. Still, it’s best to check them regularly and replace them sooner if they appear dirty.

How to Change Your Furnace Filter
Changing your furnace filter is a simple task most homeowners can handle:
-
Locate the filter, typically in the blower compartment or an attached duct.
-
Turn off the furnace before removing the old filter.
-
Insert the new filter in the same direction, ensuring the airflow arrow points toward the furnace.
