These woolen balls from Eco-Sisters look like cat toys, but they’re actually terrific energy savers.
Toss a couple in the dryer and they’ll reduce your drying time by up to 40 percent. The wool removes static and helps soften fabrics, and they are safe and clean as can be, unlike most dryer sheets (which, in addition to using synthetic fragrances, may contain toluene and styrene, two potentially carcinogenic neurotoxins). Made from recycled sweaters, so every set is unique. $20 per pair at Eco-Sisters, www.ecosisters.net.
