How Often Should I Change My Air Filters and Which Type Should I Buy?

Changing the air filters in your heating system is an important part of maintaining the heating system in your home. It also helps improve indoor air quality. How often you change it and what type to get really depends on your heating system. Consult your owner’s manual if you aren’t sure, but most filters should be changed once a month, especially during times of heavy use. Contact The Clean Air Act for all HVAC services, including indoor air quality in Beaverton.

Some heating systems have a removable filter that you can clean instead of throwing it away. These are better for the environment and also tend to be slightly more effective, but only if you clean them often. You should check them at least once a month if not more often. If you have pets or allergies, it’s probably a good idea to check them as often as you can.

Some disposable filters are designed to last up to three months. When you buy your air filter, it should have the instructions on the package. You’ll also need to make sure you know which size and type to buy before you purchase it. Some furnaces or heat pumps will have the instructions on the door to the filter, or you can check the owner’s guide. You can also take in the old filter to the store with you so that you know exactly which type and size to get. Most air filters can be purchased at your local hardware store, but it might be a good idea to call first to make sure they have the right kind.
