Dohm vs LectroFan: which white noise machine should you buy?
Yogasleep Dohm Classic vs LectroFan Classic: real fan vs digital noise, volume control, timer, power, and travel — plus two alternatives when neither fits.
Short answer: Buy the Dohm Classic if you want the most natural, set-and-forget fan sound and your room is only moderately noisy. Buy the LectroFan Classic if you need precise volume control, a sleep timer, more sound choices, or something small enough to pack. Neither one loops: the Dohm uses a real fan, and the LectroFan generates its sounds continuously.

Sound: a real fan vs generated noise
The Dohm makes its sound mechanically — a fan spins inside a vented housing, and you shape the tone by twisting the cap and collar. That is why people who find electronic noise grating often settle on it: there is no speaker and nothing to loop. The LectroFan generates its sounds digitally, which buys you variety: a range of fan sounds plus white-noise profiles that run from brighter to deeper and rumblier. If you already know you like the sound of a box fan, the Dohm is the safer bet. If you want to experiment until something disappears into the background, the LectroFan gives you more to try.
Volume: which one handles loud neighbors
When the problem is traffic, a thin apartment wall, or a snoring partner in the same room, volume headroom decides it. The LectroFan has precise volume steps, so you can run it barely audible or turn it up well past the Dohm. The Dohm's range is limited to its two speeds and how far you open the vents. Its stepped volume range is wider than the Dohm’s two speeds. For loud, irregular noise, start with the LectroFan. For a steady hum or quiet suburb, the Dohm is usually plenty.
Simplicity, timer, and power
The Dohm is one switch and two speeds, with no screen and no app, and it runs until you turn it off. Nothing to program, which is the point. The LectroFan adds a built-in sleep timer and runs on USB power, so it works from a laptop, a USB wall plug, or a hotel nightstand. The Dohm plugs into a standard 120V outlet with its 7-foot cord.
Light sleepers
Light sleepers who wake at small sounds often do best with fine control: the LectroFan's volume steps let you set the sound just loud enough to cover the disturbance. The Dohm suits people who find a real fan more relaxing than any recording. Neither is a medical device; if sleep problems persist, talk to a doctor.
Our picks, with the tradeoffs
1. Best natural fan sound
Yogasleep Dohm Classic
Yogasleep has made the Dohm since 1962, and it is our suggestion when digital noise sounds fake to you. Flip the switch, pick a speed, twist the housing until the tone disappears into the room.
Pros
- Real mechanical fan sound — nothing to loop
- One switch, two speeds, no app or screen
- Assembled by hand in the USA, per Yogasleep
Cons
- No sleep timer
- Only one type of sound
- Less volume headroom for loud environments
- Needs a 120V wall outlet
Best for: Light-to-moderate noise, people who dislike electronic sound, set-and-forget bedrooms and nurseries.
Skip if: You need to drown out loud, irregular noise or want to travel with it.
2. Best for volume control & travel
LectroFan Classic White Noise Machine
The pick for noisy apartments and frequent travelers: 20 non-looping sounds, precise volume, a built-in timer, and USB power in a compact body.
Pros
- 20 non-looping fan and white-noise sounds
- Precise volume — very quiet to loud
- Built-in sleep timer
- USB-powered and compact for travel
Cons
- Generated sound — some people hear it as electronic
- More buttons to learn than the Dohm
- Plastic build feels less substantial
Best for: City bedrooms, thin walls, light sleepers who want fine volume control, and travelers.
Skip if: You specifically want the sound of a real fan.
3. Best when only you need masking
soundcore Sleep A20 Earbuds
If your partner hates white noise but you need it, a room machine will always be a compromise. Sleep earbuds keep the sound in your ears.
Pros
- Masks noise for you without filling the room
- Small in-ear design meant for sleeping
- Travel friendly
Cons
- In-ear comfort is personal — use the return window
- Needs charging
- Costs roughly three times either machine
Best for: Couples who disagree about sound, and travelers.
Skip if: You dislike anything in your ears overnight.
4. Best if screens are the real problem
Hatch Restore 3
When you're up because your phone is on the nightstand, a better noise machine won't fix it. Restore 3 combines sound, a sunrise alarm, and wind-down routines so the phone can leave the room.
Pros
- Sound, sunrise light, and routines in one unit
- Replaces the phone as an alarm clock
Cons
- Costs about three times a Dohm or LectroFan
- Some content and features run through the Hatch app and subscription
Best for: People who want to get the phone off the nightstand.
Skip if: You only need noise masking — buy a Dohm or LectroFan.
How to choose
- Match the machine to the noise
- Steady, moderate noise (a hallway, a quiet street, a fridge) is Dohm territory. Loud or irregular noise (sirens, neighbors, snoring in the same room) needs the LectroFan's volume headroom. If only one person in the bed wants masking, look at sleep earbuds instead.
- Volume control you'll actually use
- The goal is the lowest level that hides the disturbance. Precise steps (LectroFan) make that easy; two speeds plus vent adjustment (Dohm) works if your room is consistent.
- Timer or all night
- Want the sound to stop after you fall asleep? You need a timer, and the Dohm doesn't have one. If you wake to silence and then notice every noise, running all night is usually better.
- No loops
- Cheap track-based machines can have an audible restart point that your brain learns to hear. Both of these avoid it: the Dohm is a real fan, and the LectroFan generates non-looping sound.
- Power and placement
- The Dohm needs a wall outlet; the LectroFan runs from USB. Place either one between you and the noise source (often near the door or window), not right beside your head.
