How to Tell the Difference Between a Lint Trap and a Dryer Vent

Dryers are essential household appliances—but when it comes to keeping them running safely and efficiently, many people confuse two important components: the lint trap and the dryer vent.

Although they both play a role in removing lint and improving airflow, they’re not the same thing. And knowing the difference could help you prevent dryer fires, reduce energy bills, and extend your dryer's lifespan.

Let’s break it down. 

What Is a Lint Trap?

The lint trap (or lint screen) is the mesh filter you can easily see and access inside or on top of your dryer. Its job is to:

  • Catch lint and fibers from your clothes during drying
  • Prevent lint from entering the dryer's ventilation system
  • Improve efficiency by maintaining good airflow

Where it's located:

  • Inside the dryer door frame
  • On top of the dryer
  • Sometimes along the back edge of the drum

How to clean it:
You should clean your lint trap after every load. Simply pull it out, remove the lint, and put it back in place.

Pro Tip: Occasionally rinse the screen with soap and water to remove buildup from dryer sheets or fabric softeners.

What Is a Dryer Vent?

The dryer vent is the exhaust duct that leads from the back of your dryer to the outside of your home. Its job is to:

  • Expel hot air, moisture, and any lint that escapes the lint trap
  • Ventilate the dryer safely so it doesn’t overheat
  • Prevent mold and mildew by removing excess moisture

Where it's located:

  • Starts at the back of your dryer
  • Runs through a wall or ceiling to an external vent cover

How to clean it:
Dryer vents should be professionally cleaned at least once a year. A clogged dryer vent is a serious fire hazard and a leading cause of home dryer fires.

Did you know? According to the U.S. Fire Administration, failure to clean dryer vents causes thousands of residential fires each year.
