Why Do Dryers Produce Lint?

Lint is a natural byproduct of putting clothing or other fabrics through the machine drying process. Your dryer tumbles fabrics, causing them to press and bump against each other and the internal parts of the machine. That creates friction, which pairs with the heat inside the dryer to break down fabric fibers.

Each time clothing goes into the dryer, tiny fibers break away from the fabric. They combine to form lint.

How Does Lint End Up on the Lint Filter?

The hot air and moisture in your dryer need to go somewhere, and a vent system pushes it out of the home. All the small fibers that break away from fabric during the drying process would be carried out as well, which is why the air passes through a filter first. The filter captures the tiny fibers, which is what creates the thin layer of lint you pull off of it with each laundry cycle.

Why Is My Dryer Producing Excessive Lint?

Having to clean your dryer lint trap every time you use the machine is normal. This level of dryer vent cleaning is actually a recommended everyday task that helps keep lint from building up to concerning levels in your machine.

However, even if you clean your lint trap regularly, you might notice excessive amounts of lint when you dry clothes.

Here are some common causes of excess lint:

Blocked Vent System

Why It Creates an Issue

Lint can build up in the duct, backing up into the dryer.

Potential Fix

Try vacuuming your dryer vent and duct to remove any buildup.

Dirty Lint Screen

Why It Creates an Issue

More particles than normal build up on the screen.

Potential Fix

Gently clean the screen with a dryer vent brush or with mild soap and water, depending on the care instructions in your dryer's manual.

Dryer Overloading

Why It Creates an Issue

Lint gets trapped inside clothing and the machine instead of being pushed out to the filter.

Potential Fix

Reduce the size of laundry loads you put in the dryer.

Certain High-Shed Fabrics

Why It Creates an Issue

New fabrics tend to shed more, and materials like fleece or chenille lead to higher lint volumes in general.

Potential Fix

Process smaller loads of this type of fabric if lint buildup becomes concerning.

Using High Heat or Over-Drying Clothing

Why It Creates an Issue

Fabrics break down faster than they should, leading to more lint.

Potential Fix

Follow the instructions for your specific dryer model for how to care for certain clothing, and avoid running items super long on high heat settings.

Damaged Dryer Components

Why It Creates an Issue

Poor dryer efficiency or operation can damage fabrics and lead to higher lint output.

Potential Fix

Get professional service to repair parts or replace the dryer.

How Much Is Too Much Lint?

Most of the time, your lint filter will only be partially full of lint. If you only see excess lint when you dry fleece blankets or new sweaters, that's likely normal. Signs you might have too much lint include:

• Every load you dry leaves enough lint to stuff the trap or overflow it.

• You find clumps of lint behind or near your dryer.

• Lint is hanging out of or blowing out of your exterior vent cap.

• Your dryer isn't drying completely or takes forever to dry clothing.

• You smell a burning smell when you run the dryer.

If you notice any of these signs, you may have dryer vent safety concerns that require addressing. A dryer clogged with lint creates a fire hazard, so avoid running the dryer until you can address the issues, especially if you won't be home. If the DIY measures from the table above don't work, consider calling a dryer maintenance professional to inspect your unit.
