These devices are available in several different scents. The Air Wick Life Scents air fresheners feature several combined scents intended to mimic more natural fragrances. For example, one popular model combines flower, melon and vanilla. The Air Wick Freshmatic and the Glade air freshener feature more typical scents, such as fresh water and Hawaiian breeze.
Some other battery-operated air fresheners include the Lysol Neutra Air Freshmatic Automatic Spray Air Freshener and the BestFire Mini Ionic Freshener Deodorizer Purifier. The Lysol device is similar to the Air Wick Freshmatic and Glade air freshener. However, the BestFire purifier is an air freshener that neutralizes unpleasant odors by trapping scent particles and killing airborne bacteria. It is principally designed for use in enclosed areas, such as refrigerators, closets and bathrooms. Unlike the other devices, it does not use a fragrance; instead, it works to eliminate unpleasant smells.Learn more about Smell Removal
