Abstract
Paper coffee filters are stacked one atop another and packaged within a container, such as a carton or a plastic bag. The paper coffee filters define a cavity within the container in which is placed a water filter device comprising activated carbon. The paper filters are used to filter coffee grounds or the like from a brewed beverage. The water filter device is used to filter impurities from the brewing water before the brewing process. The disclosed packaging arrangement reduces packaging costs and serves to notify users that their existing water filter device has reached the end of its useful life because the coffee filters and the replacement water filter device are provided in a unitary package.
