Have you been looking for an easy resource with tips on How to Change an Air Filter?

Changing your home air filter is a quick, easy way to keep your air conditioner, furnace, or central air system running efficiently. Maintaining a clean air filter can keep your energy costs down, and it is one of the items on our Resident Maintenance Responsibility Checklist.

Check your filter at least once a month when it’s being used often, and change the filter at least every 3 months.

  • Look for a label on your unit that says which filter will fit. Many air units have labels somewhere on the exterior that will say which kind of filter to buy. Check any visible parts of your unit for a label.
  • Take a picture of your current filter to the store. The best way to ensure that you get the right filter is to match it with the one already in use. Take out the current filter and see if it has a label or number. Take a picture of any information written on the filter and of the filter itself to help you match it in the store. You can also take the old filter itself to the store, but make sure you leave your unit turned off while the filter is removed. You should also look for the arrow marking on the outside of the filter and make a note of which way it’s pointing so you will know which way to install the new one.
  • Remove the old filter. The filter should slide out easily. Be careful when removing it, as it may be covered in dirt and dust that could come loose and make a mess if handled too roughly.
  • Make a note of when you replaced the filter. This will help you keep track of how often you’re changing the filter, and ensure that you remember when it’s due for a check. Make a note with your phone or computer, or write it down somewhere that will be easy to keep track of!
