Ask Kim - Changing Your Home's Air Filter

Do you need to swap out your home's air filter? In this episode of Ask Kim, you'll learn how to change your filter, and when to do it.

Hi this is Kim with SaveOnEnergy, here to answer your energy savings questions.

Today's question comes from Gene in Houston who asks, "Do I really need to change my home's air filter every 30 days?"

Changing your air filter is a must to keep your heating and air conditioning system working efficiently, but you may not have to swap it out every 30 days. Depending on the type of air filter you have, you may not have to change it for several months. Today we'll show you how to tell if you need to change your air filter, and how to do it.

The first step is to locate where your air filter is installed. After you remove the grate, inspect the filter. It's normal for filters to get dirty. After all, that's what they're there to do!

If your filter is visibly soiled and you're not sure how long it's been since you installed it, it's a good idea to replace it as soon as possible. If you kept track of when you installed your filter, don't worry about replacing it until the end of the manufacturer's suggested lifespan. Just be sure to check your old filter before you go to the store to make sure you purchase the correct size.

To swap out your air filter, open the intake grate and remove the old filter. Sometimes there's something holding your filter in place, but it should come right out once the grate is open.

Check your new air filter for the proper air-flow direction, and place it in front of the open duct. Then replace the grate, and you're done!
