Dryer balls are a simple and cost-effective way to soften your clothes, reduce static, and speed up drying time all while saving energy. Made of wool or plastic, they work by bouncing around in the dryer, separating the clothes and allowing hot air to circulate more efficiently. In addition to helping you save money on energy bills, they're also a great eco-friendly alternative to dryer sheets as they're reusable and chemical-free. Simply toss them into the dryer with your load of laundry and enjoy softer, fluffier clothes with less static cling.
