Diffuser Length: Up to three hoursAbout the Diffuser: This home diffuser uses ultrasonic vibrations to atomize water and fragrance oil to release fresh fragrance without heat, maintaining the integrity of the fragrance oil. Designed with simplicity in mind, the one-button operation elevates the ambience for up to three hours, and the automatic safety shut-off allows you to relax and enjoy. The diffuser is cordless, rechargeable, and portable, allowing your favorite fragrances to move freely with you. The silhouette masters the elegance of symmetry and is built to last. Anchored by a weighted matte-white metal body and styled with signature Voluspa embellishments, the design is as flawless as the experience. Create a scent combination that’s unique to you and personalize strength to your liking—add more drops of fragrance oils to amplify the ambience, or less for sensitive noses. Your fragrant companion will scent up to 500 square feet. Punctuate your day with this olfactory soundtrack to your life.
