How Often to Change a Home Air Filter Video Transcript

Hi, I'm David. Welcome to Frequently, we get asked, "How often should I change my air filter?". Changing your air filter is the easiest and most effective way of maintaining your home's cooling and heating system.

A dirty air filter restricts airflow, which leads to bad air quality, higher energy bills, and over time will cause your system to ultimately fail. Figuring out how often you need to change your air filter will depend on where you live, the time of year, the filter material, and the efficiency of the filter you select.

This is a fiberglass filter. It's a low cost, disposable filter, but you'll need to change it every 30 days or less. Why? Because it's less efficient in capturing dust and particles in the air.

This pleated air filter is also disposable, but more efficient than fiberglass and lasts longer: up to 90 days depending on use.

If your air filter typically lasts 90 days, you should change it every 30 days during peak summer and winter months, when your system works the hardest.

Now you're ready to choose the right air filter to help maintain a clean and healthy environment for you and your family. Remember, proper maintenance of your home's cooling and heating system will maintain good air quality, increase the lifespan of your system, and consume less energy to help lower your bills.
