Fan sound vs real fan
A real fan dries your eyes and throat and makes the room colder. A fan sound gives you the same masking effect with no draft — and you can take it anywhere: hotels, trains, dorms.
Frequently asked questions
Why can't I sleep without a fan?
Many people get used to the constant sound of a fan, which masks small noises that would otherwise wake them. A fan sound recreates that without the draft or the electricity bill.
Is it safe to sleep with noise on all night?
For adults, yes at a moderate volume — keep it quieter than a normal conversation (below about 50–60 dB). For babies, place the device at least 2 meters (7 ft) from the crib and keep the volume low, as recommended by the American Academy of Pediatrics.
Does it work with my phone screen off?
Yes on most phones: the sound is played like music, so it keeps going when the screen locks. If your phone stops it, keep the screen on with low brightness, or add the page to your home screen.
