Environment Scent Machine is the latest diffusion technology to enjoy the fragrance of your favorite inspired-by-famous-hotel scents and designer perfumes throughout your home or business. This innovation harnesses cold-diffusion technology and nebulizes fragrance that is healthy for your pets and children. Utilizing scent with air diffusion, the Environment Scent Machine turns fragrance oil into a fine mist, and with this method the scent stays in the air longer.
