How Often Should I Change My Filter?

Video: How Do I Change My Filter?

How often you need to change your furnace or air conditioner filter will depend on the type of material and efficiency of the filter you select.

  • Fiberglass Filters – Fiberglass filters are a low cost, disposable solution but need to be changed every 30 days or less.
  • Pleated Filters – Pleated furnace filters are also disposable but typically have better efficiency than fiberglass and can last longer – up to 90 days depending on the season.
  • Important Factors – Where you live and the time of year are also important factors that will impact frequency. According to Energy Star (, filters that would typically last 90 days should be changed every 30 days during peak summer and winter months. This is when HVAC systems are operating at max capacity and thus require maximum efficiency to continue running smoothly.
  • Things to Remember:
  • Regular maintenance of your home’s cooling and heating system is essential to ensure it operates efficiently. Proper maintenance will keep good air quality in your home, increase the life span of your system, and consume less energy to help lower your bills.
