Cold drafts sneaking in under your doors during the winter aren't just a nuisance—they can also cost you money. According to the U.S. Department of Energy, by plugging drafts in your home, you could potentially cut your energy bill by 10 to 20 percent. And one of the simplest and cheapest ways to start chipping away at these air leaks is with a draft stopper that attaches to the bottom of your door, like this one on Amazon for $10.

By using this door draft stopper, not only will you stop feeling the cold air whooshing through your home, but you'll also keep dust, noise, light, and bugs out. You can use this door draft stopper on your home's door frames or even on your garage door to keep wind, snow, and rain from getting indoors.

The stopper is 39 inches long, so you can cut as much or as little you need depending on the door you want to seal off. The durable, waterproof adhesive is immensely helpful when thinking about keeping water from leaking out of shower doors. You'll no longer be greeted by unexpected lakes appearing on your bathroom floor when exiting your shower.
