How Often Should I Change My Air Filter?

Video: How Often Should I Change My Air Filter?

It is important to switch your air filters regularly to keep your indoor air quality at its best. Also, by installing a new air filter, your AC unit will work more efficiently and lower your energy bills. 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 (MERV 8, 11 or 13) – These are also disposable but are more efficient than fiberglass at trapping pollutants and last longer – up to 90 days depending on the conditions of your home.
  • Important Factors – if you suffer from allergies or asthma, have pets or live with a smoker, you should install an air filter rated MERV 8 or higher and change it every 30 days.
  • Things to Remember – As days go by, filters become clogged with dust and debris and lose efficiency. Also, during peak seasons like summer or winter, when your unit is operating at its highest capacity, you should change your air filter more often to prevent breakages.
