Most people toss silica gel packets the moment they open a new box of shoes or electronics. But these tiny packets are far more useful than they seem. Silica gel is a desiccant, meaning it absorbs moisture from the air — and that simple property makes it a household lifesaver in dozens of situations. Instead of throwing them out, try these clever ways to put silica gel packets to work around your home.

What Is Silica Gel and How Does It Work?

Silica gel is made from silicon dioxide, a naturally occurring mineral that’s processed into small, porous beads. These beads attract and hold moisture on their surface, keeping the surrounding area dry. While not edible, they’re perfectly safe to use for moisture control in your home.
