TimeWick air freshener system is completely passive and requires no power source to deliver 60 consistent days of premium air freshening. Starter kit includes one dispenser and one Mango Smoothie refill. The Mango-scented essential oil releases into the dispenser reservoir at a steady rate, and the sintered polymer wick quickly absorbs the oil and releases the fragrance into the air. The oil's continual evaporation off the wick distributes the fragrance evenly. As the wick dries out, capillary action drives oil to any porous spots so the wick is refilled until the oil has evaporated. The tamper-resistant dispenser covers 3,000 cubic feet. The fragrance contains high-powered odor-counteractants.
