You know them as the key to a well-caffeinated morning. But here, paper filters moonlight as useful household helpers.
Layer a filter between mugs, bowls, and plates to prevent chips and nicks.
Fill filters with baking soda, tie with ribbon or floss, and stash in smelly spots, like sneakers or a trash can.
More durable than a paper towel and not lint-shedding like a cloth, a filter works well with glass spray on mirrors and windows.
