The Sheraton Scent Diffuser utilizes cold-air diffusion to convert fragrance oil into a dry nano-mist that is dispersed into the air. This allows the particles to stay suspended in the air and to be distributed throughout your room or office. The Sheraton Scent diffuser uses no heat or water which preserves the aroma of your favorite fragrance oil. The mist that is generated by the diffuser is residue free and safe for children, pets, and furniture. Remote control included that allows you to set diffuser concentration and run time.
