Yogasleep Dohm Classic
Real fan, non-looping; 2 speeds and a tone collar.
- Real fan
- No loop
- Plug-in
Short version: the Yogasleep Dohm Classic is better if you want the natural, non-looping sound of a real fan and dead-simple controls. The LectroFan Classic is better if you want more sound choices, precise volume and a compact unit that runs from USB for travel.
The Dohm Classic makes sound with a real fan inside; you choose between two speeds and twist the collar to adjust tone. It plugs into the wall. The LectroFan Classic is electronic, with 10 fan sounds and 10 white, pink and brown noise options, fine volume steps, and USB or AC-adapter power. Neither has a night light or app.

Because the Dohm’s sound comes from a real fan moving air, there is no loop or repeating pattern, which some sleepers notice with electronic machines.
Controls are a switch and a twist collar. There are no sound libraries or screens to fiddle with at 2 a.m., and no app.
If one fan sound doesn’t suit you, the LectroFan lets you switch among fan, white, pink and brown noise and set the volume in small steps.
USB power makes it easy to run from a laptop or power bank in a hotel. Its fan sounds are electronic recreations, not a real fan.
Listen to both if you can. People who dislike any hint of looping usually prefer the Dohm.
Real fan (Dohm) vs electronic fan and noise (LectroFan).
Speed switch and tone collar vs buttons with fine volume.
Wall plug (Dohm) vs USB or AC adapter (LectroFan).
Neither has a night light or app; see Hatch Rest for those.
For options and travel, yes. For the most natural, non-looping sound, the Dohm is better.
No. It uses a real fan, so the sound doesn’t repeat.
20: 10 fan sounds and 10 white, pink and brown noise variations.
Yes, from USB or an AC adapter.
