Convenient air freshener is easy-to-use and maintenance-free—doesn't depend on batteries, fuel cells or any other artificial means of power. Contains a molecular odor counteractant that effectively fights odors, rather than merely masking them. Provides 60 full days of odor control and air enhancement. One refill cartridge covers 6,000 cubic feet. Easy-to-use; simply twist to activate—it only takes seconds. Small enough to fit into most dispensers on the market.
