Dryer Max brand Dryer Balls, at about $10 for two, is a smart, eco-friendly purchase. The blue, spiky balls serve the same purpose as dryer sheets, but they help dry your clothes quicker (thereby using less energy) and they last for years.

I’ve seen online reviews of dryer balls that say they do not actually cut drying time, nor do a sufficient job of removing static cling and softening clothes and linens. While I have not measured drying time since I purchased the Dryer Balls, I have quit using dryer sheets (which contain chemicals and produce waste) and have no complaints about how my laundry is turning out.

If you want a quick, cheap way to make your household greener, think about investing in these hot blue balls!
