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. 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. A new 1" pleated air filter? Less than $20.

1LOCATE 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.

2REMOVE AND EXAMINE YOUR CURRENT FILTER

If you're not sure whether or not it's time to change your filter, hold your dirty filter up to the light. If you can no longer see through the filter, than it's time to change it.

3CHOOSE YOUR NEW FILTER

If you simply want to protect your blower motor from dirt, then go for the least expensive filter option. 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 $20). For pollutant-free air, your best option is a HEPA filter, which removes 99.97 percent of all particles greater than 0.3 micrometer. They do cost more ($30-$80) but you can rest assured they'll clean your air better than anything else. Note: More expensive filters will capture more dust, pollen and pet danger, which means they'll become clogged faster and air flow will get restricted. Restricted air flow can lead to premature furnace failure, so it's really important that you change more expensive filters regularly!

4CHANGE THE FILTER

You're finally read 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.
