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 ups the ambiance for 3+ 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. Includes charging cable.
