Our verdict

Where it wins

  • 20 distinct, non-looping sounds so you're not stuck listening for a loop point
  • Loud enough to mask traffic, snoring, or noisy neighbors even on low settings
  • Small and USB powered, easy to pack for travel
  • Simple dial controls, no app or account needed

Where it loses

  • No display, so you have to cycle through all 20 sounds to find your favorite each time
  • Timer maxes out at 60 minutes; the pricier LectroFan Evo goes up to 8 hours
  • No battery, needs to stay plugged into USB power

The LectroFan Classic is a straightforward digital noise machine that masks background sound without any smart features to fuss with. It is a good fit for anyone who wants a reliable white noise machine at a low price and doesn't care about an app or night light. The lack of a display makes flipping through 20 sounds a little tedious, but the core noise masking works as advertised.

Common questions

Does the LectroFan Classic need batteries?

No, it runs on USB power through the included cable. It has no built-in battery, so it needs to stay plugged into a USB port or wall adapter.

Can I set it to run all night?

Yes. The sleep timer is optional, if you don't set it, the machine runs continuously until you turn it off.

Is the sound real fan noise or digital?

It's digitally synthesized noise, not a recording of a fan. Adaptive Sound Technologies designs the tracks to be non-looping so you don't hear an audible repeat.
