WHY DO THIS?


In less than two minutes, you can ensure that the air you breathe is clean, reduce household dust and prolong the life of your furnace. Plus, by replacing your air filter, you’ll be ahead of the game – only one in five Americans currently pays attention to their furnace filters! A new furnace will cost you anywhere from $3,000 to $5,000 dollars. A new fiberglass air filter? Less than $10.

EASY

How To:

  1. 1

    Locate your current filter. Some filters will be located in the bottom, some in the back and some in the front (but behind a panel). If you have trouble finding your furnace’s filter, check your owner’s manual for the location.

  2. 2

    Remove and examine your current filter. Most fiberglass air filters are blue. If it’s any other color, it’s time to change it! If you have a white fiberglass air filter, hold it up to the light. If you can no longer see light passing through the filter, than it’s time to change it.

  3. 3

    Choose your new filter. If you simply want to protect your blower motor from dirt, then go for the least expensive option (there are fiberglass filters available for as low as $2)! However, if you’re more interested in keeping your air free of pollutants, however, opt for a middle-of-the-road price when shopping for filters (about $10-$15). Remember, fiberglass filters are the least effective filter option if your goal is reducing household allergens. If you have serious allergies, consider using 1" pleated filters instead. Just make sure that whatever filter you choose is the right size for your furnace. Note: More expensive filters will capture more dust, pollen and pet dander, which means they’ll become clogged faster and air flow will get restricted faster. Restricted air flow can lead to premature furnace failure, so it’s really important that you change more expensive filters regularly!

  4. 4

    Change the filter. You’re finally ready to change the filter! Pull the dirty filter out and replace it with a new one. Make sure that the arrow on the filter is pointing towards the blowing motor. Done. Note: If you’ve removed a panel on your furnace, replace it now.
