An aromatizer is a device or substance used to emit pleasant odors or fragrances in a room or environment. There are several synonyms for the term, including diffuser, scent dispenser, fragrance dispenser, air freshener, perfume atomizer, and mister. Diffusers are usually used with essential oils and are known for their therapeutic benefits. Scent dispensers and fragrance dispensers emit a range of fragranced mists into the air. Air fresheners are often found in commercial settings and are designed to freshen the air and eliminate unpleasant odors. Perfume atomizers are small handheld devices that dispense a fine mist of fragrance. Lastly, misters use water-based solutions and fragrances to mist a room and create a fresh and pleasant atmosphere. All these words refer to the same instrument that helps to emit beautiful fragrances into the air.
