The Pollution Coming Out of Your Dryer: Why We Support the 5 Gyres Institute

Most of us picture plastic pollution as a bottle on a beach or a bag drifting in the surf. The truth is stranger and far closer to home. Some of the most pervasive plastic in our environment is flowing out of the vent on the back of the clothes dryer.

The Problem We Cannot See

Synthetic clothing sheds tiny plastic threads called microfibers every time it is washed and dried. For years the conversation focused on washing machines and wastewater. Then researchers at the 5 Gyres Institute asked a question almost no one had studied. What about the dryer?

The answer was sobering. Dryers turn out to be a major and overlooked source of airborne microfiber pollution. A single laundromat can release trillions of fibers into the air each year. These particles do not just settle on the ground. They are light enough to breathe, and scientists have now found microfibers in human lungs, in placenta, and even in brain tissue. The plastic we wear is quietly becoming the plastic we inhale.

A Solution You Can Install

Here is what we love about 5 Gyres. They do not stop at sounding the alarm. They go looking for fixes that an ordinary household can actually use. Their recent work, done in partnership with Ocean Wise, tested simple secondary filters that attach to home dryers. The best of them captured up to 80 percent of the microfibers before they ever reached the air. If every household in the country installed one, the researchers estimate we could keep hundreds of trillions of fibers out of the environment every single year.

That is the kind of science CHF is built to support. Rigorous, original, and pointed squarely at a solution.

Why We Support It

For more than a decade, 5 Gyres has done the unglamorous primary research that turns a vague worry into hard evidence, and then into policy and product. They were studying ocean plastic before most of the world was paying attention, and they are still uncovering new fronts in the fight, including the one humming away in the laundry room.

Our Environmental Science pillar exists for exactly this kind of partner. The problem is enormous and invisible, the science is sound, and the path to impact runs straight through everyday life. We are proud to support the 5 Gyres Institute, and the next time you hear the dryer running, you will know why.
