Whoof is a professional-grade air freshener that neutralizes unpleasant odors fast. It whisks odors away in just five seconds and refreshes stale air. Whoof is the new and safer way to spray odors and smoke away, and refresh the air. Its Time-Released odor wick action continues to vaporize slowly to combat odors that don’t quit. Whoof can be used with foggers, sprayed, mopped, or applied with a sponge.
