Changing the furnace’s air filter can significantly improve its ability to heat your house. Dirty filters restrict airflow, meaning the system uses a lot of extra energy to keep up with your heating demands. They also cause your home to accumulate lots of dust and dirt. If you have allergies or asthma, a dirty filter can even cause your symptoms to worsen. How often should you change your furnace filter? The answer to that question depends on a few factors.

How Often Should You Change the Filter?

The most important factor that impacts how often you should change the furnace filter is its size. Thinner filters require more frequent changes. We suggest having a licensed technician inspect your furnace to tell you how often to change the filter. However, as a basic guideline, you can use the following suggestions to determine whether you need to change the filter on your furnace:

  • One- to two-inch filters: Change every one to three months
  • Three- to four-inch filters: Change every six to nine months
  • Five- to six-inch filters: Change every nine to 12 months

The Value of a High-Quality Filter

You have many filter options to choose from. However, using a higher-quality filter provides several advantages for your home. It not only makes the heater more efficient, but it also provides better heat distribution. The energy savings a clean filter provides decrease your heating bills while also extending the lifespan of the heater. Experts agree that furnaces that receive regular maintenance last longer than those that don’t receive proper care. They also agree higher-quality filters lead to better indoor air quality.
