It might seem harmless—just tossing a load of laundry into the machine and hitting start—but tucked inside that spin cycle is a quiet contributor to one of the biggest pollution problems we rarely see: microfibers.
These tiny threads, often shed from synthetic fabrics like polyester (which appear in everything from activewear to dryer sheets), don’t disappear after a wash. Many slips through wastewater treatment systems during laundering and eventually enter rivers, oceans, and even farmland when treated sludge is used as fertilizer. And those polyester dryer sheets? They add to the problem in a different way—by coating clothes with synthetic chemicals and shedding microplastics into the air during drying.
Synthetic textiles are one of the biggest sources of microplastic pollution, responsible for nearly 35% of the microplastics in our oceans. A single load of laundry can release up to 18 million microfibers. Between 1950 and 2016, 5.6 million metric tons of synthetic microfibers were estimated to be released into the environment through clothes washing. That’s like dumping over 28 billion T-shirts into nature.1
What’s the eco-friendly way to soften clothes without contributing to pollution? Try wool dryer balls instead of dryer sheets.
What Do Dryer Balls Do?
Dryer balls may seem simple, but they work wonders to make your laundry routine more efficient and eco-friendly. When added to the dryer, they tumble around with your clothes, creating gaps that allow warm air to circulate more effectively. This boosts drying efficiency, reducing both drying time and energy consumption. The result? Lower utility bills, softer clothes straight from the dryer, and a smaller environmental footprint from your appliances.
Now, not all dryer balls are created equal. If you aim for a low-waste, microplastic-free laundry routine, wool dryer balls are the way to go. Unlike plastic or synthetic options, wool dryer balls are made from natural fibers that won’t shed harmful microplastics into your home or the environment.
Wool dryer balls also double as natural fabric softeners. As they bounce around, wool dryer balls gently fluff your clothes, helping to reduce static and soften fabric—all without the synthetic fragrances and questionable chemicals found in many dryer sheets. So, if you’re looking for a more sustainable, plastic-free swap that actually works, wool dryer balls are the better choice for both your laundry and the planet.
How They Help Reduce Microplastics
Here’s where dryer balls shine in the battle against microplastic pollution. Unlike dryer sheets, which are made of synthetic materials that shed tiny plastic fibers into the air and onto your clothes, dryer balls are typically made from natural materials like wool. These natural dryer balls don’t shed any synthetic fibers as they tumble in the dryer. This means you won’t release more microplastics into your laundry, home, or environment.
Using dryer balls can help prevent the shedding of microplastics that typically come from synthetic fabrics. When clothes are tumble-dried with dryer balls, they create less friction, which helps reduce the number of microfibers that break off during the drying process. So, dryer balls are a more sustainable alternative to dryer sheets and help keep those harmful microplastics from finding their way into your laundry and out into the world.
Dryer Balls vs. Dryer Sheets: Key Differences
What’s Inside Dryer Sheets?
Dryer sheets are typically made from synthetic fibers, such as polyester, which are often coated with fragrances and chemicals. These synthetic materials can shed microplastics during drying, adding to the pollution in our air and water. On the other hand, dryer balls are crafted from natural materials like wool or rubber, offering a plastic-free, chemical-free alternative.
The Environmental Toll of Dryer Sheets
One of the major environmental concerns with dryer sheets is their contribution to microplastic pollution. Each use releases synthetic fibers that can end up in the air, your clothes, and eventually our waterways, harming marine life and ecosystems. Dryer balls, however, have a minimal environmental footprint. They are reusable, which helps reduce waste, and since they’re made from natural, biodegradable materials, they don’t shed microplastics or release harmful chemicals.
How They Work Differently
Dryer sheets soften clothes by coating them with chemicals, adding a scent and reducing static cling. This method, while effective, involves synthetic compounds that stay on your clothes and may contribute to indoor air pollution. Dryer balls, on the other hand, work by tumbling through the load with your clothes, separating fabrics and improving airflow to speed up drying. They naturally reduce static and soften your clothes without relying on artificial chemicals or fragrances.
The Cost of Convenience
While dryer sheets need to be replaced after every load, adding to the ongoing cost and waste, dryer balls are a long-term investment. A single set of dryer balls can last for years, making them a more sustainable option in the long run. Since they are reusable and free from plastic, they also help reduce landfill waste.

Crafted from 100% premium New Zealand wool, these dryer balls are designed to soften fabrics, reduce wrinkles, and decrease drying time. By gently tumbling with your laundry, they help separate clothes, enhancing air circulation and leading to more efficient drying cycles.
How to Use Dryer Balls
Just toss ’em in with your laundry and let them do their thing! As they bounce around, dryer balls help separate your clothes, which boosts airflow and cuts down drying time—hello energy savings. Bonus: they naturally reduce wrinkles and static, so your laundry comes out soft, fluffy, and chemical-free. No effort, no fuss, just better laundry.
How Many Dryer Balls Per Load
For optimal performance, use 3 to 6 dryer balls per load. Smaller loads work well with 3 dryer balls, while larger or bulkier items like towels or bedding benefit from using more. The increased number of dryer balls helps separate fabrics more effectively, improving airflow, reducing drying time, and ensuring that clothes dry evenly.
How Long Do Dryer Balls Last
Dryer balls aren’t just a one-hit wonder—they’re in it for the long haul. Wool ones can last for around 1,000 loads. With a little care, they’ll keep your laundry routine eco-friendly for years. Just keep an eye out for signs of wear, but otherwise, toss and tumble away.
How to Clean Dryer Balls
Cleaning your dryer balls is straightforward. For wool dryer balls, toss them in the washing machine inside a mesh bag or wash them by hand. After washing, let them air dry. Regular cleaning ensures they continue to work effectively and stay in top shape.
How to Dispose of Wool Dryer Balls
Compost Them (Yes, really!)
If your wool dryer balls are 100% natural wool and haven’t been treated with synthetic fragrances or chemicals, they’re compostable. Simply cut them up into smaller pieces (this helps them break down faster) and toss them into your home compost bin. They’ll eventually return to the earth.
Repurpose Around the House
Old dryer balls still have plenty of life outside the laundry room. You can:
- Use them as natural air fresheners—just add a few drops of essential oil and tuck them into drawers or closets.
- Add them to your pet’s toy stash (if they’re not too chewed up).
- Use them as stuffing for homemade pillows or crafts.
Use Them in the Garden
Got old wool dryer balls past their prime? Don’t toss them—repurpose them! Cut them up and use the pieces to line the bottom of plant pots. They help improve drainage while still holding onto a bit of moisture, giving your plant roots a happy, balanced environment. Over time, the wool naturally breaks down in the soil and can even add a touch of nitrogen, giving your plants a slow-release nutrient boost. It’s like compost with a side hustle!
Recycle as a Last Resort
Recycling isn’t the most sustainable path here, but it’s better than sending them straight to the landfill. Regarding sustainability, the goal is always to reduce waste at every step—and even our laundry tools deserve a thoughtful sendoff.
This Has Been About Dryer Balls vs. Dryer Sheets
Laundry might not seem like a source of plastic pollution, but those tiny choices—like using dryer sheets—add up. Swapping them out for wool dryer balls is an easy, effective way to reduce microplastics, save energy, and skip unnecessary chemicals.
Pair that with a few mindful laundry habits—like washing less often, using a microfiber filter, or choosing natural fabrics—and you’re making a real difference.
