LectroFan is ideal for relaxation, study, speech privacy, or any situation where you'd like more control of your audio environment. It's also your personal white noise and fan sound machine to ensure a better night's sleep and peaceful rest. The LectroFan offers twenty unique digital sounds to block noises, and you can choose from ten different electric fan sounds and ten variations of pure white noise. All sounds can be personalized with pin-point volume control to select across a wide range of sound levels - from a whisper, to many times louder than mechanical fan based conditioners. This global power version works with 110V - 220V circuits and includes adapters for US, EU and UK AC outlets, so you can use it just about anywhere. Sleep technology has advanced beyond the outdated approach of using a mechanical fan with just a few speeds for audio variety. LectroFan is the better solution. It's entirely electronic, with no motor or other internal moving parts. You get a much better variety of sounds with adjustable volume, reproduced digitally via a large, high fidelity speaker. The steady relaxing sound of a fan or white, pink or brown noise can help you get to sleep more quickly, and stay asleep longer by helping you tune out the environmental noises that might otherwise wake you at night.
