Our natural sleep sound machine collection provides the soothing sound of a fan without the unwanted blast of cold air or other irritations. The natural sound machines are easy to use and create a natural, unobtrusive sound that fades into the background and masks noises that might otherwise wake you. By adjusting the speed and sound openings, you can customize the volume and tone to find a soothing white noise that's ideal for you. We offer three different models of our natural sound machines.
