The invention is a disk-shaped combination drink coaster and air freshener for a drink holder. The top layer absorbs condensation or liquid spills from a drink container. The disk may have a layer impregnated with an air freshener, which will gradually be released into the vehicle or room. The disk has a plurality of layers designed to absorb liquid spills and prevent liquid spills and the air freshener material from leaving deposits on the bottom of the drink holder. The device may be imprinted with advertising names or symbols. The device has perforations to facilitate tearing off part of the circumference of the disk to reduce its diameter. The disk can also be used in combination with a coaster holder impregnated with air freshener, the weight of which prevents the coaster and air freshener from sticking to the bottom of a liquid container when the container is lifted.
