If you use a dehumidifier at home, you might wonder what you can do with the tank of water it collects. First, don't use it to water plants: when humid air runs through the metal elements in a dehumidifier, it can leave trace metals. You should also never consume the water, so don't give it to your family pets. Instead, fill a toilet tank with the water, and use it to flush toilets.

Now is a good time to remove, clean and store your in-window air conditioners. This protects your air conditioner from the harsh winter elements so when it's time to re-install it, it will actually work; plus, it helps remove small cracks and crevices from your open window when you're trying to keep your home warm. If you can't remove the unit, wrap it in plastic sheeting with insulation inside, and use duct tape to secure it shut.

If you love burning candles at home, it's common knowledge that paraffin wax alternatives like soy wax will burn cleaner and release fewer pollutants into the air. But when shopping for soy wax candles, buyer beware. If a candle is simply marked "soy wax" or "soy blend," there's no guarantee that it is 100 percent soy. In fact, only 51 percent of the candle needs to be soy wax to be called a soy candle. The other 49 percent can be any wax, including paraffin. Look for candles marked 100 percent soy wax to be absolutely sure.
