The shortlist at a glance
Three machines, three different reasons to buy. All prices and figures were read from each maker's own US pages on October 21, 2026.
- Yogasleep Dohm Classic - best overall for most bedrooms. $49.99. Real fan. Two speeds, tone collar. Up to 57.4 dB at six feet. No app, no timer. 30-night trial. 1-year warranty.
- SNOOZ Original - best for loud rooms and nurseries. $99.99. Real fan. 10 steps, 46 to 87 dBA at the device. App schedules, nursery calibration. 100-night trial, return shipping paid. 1-year warranty.
- LectroFan Classic - best for sound choice and travel. $58.88, unavailable on the maker's store that day. 20 digital sounds. Sleep timer. USB power. No published decibel figure. 30-day returns at buyer's cost. 1-year warranty.
- Deciding between the two fan machines? The head-to-head is SNOOZ vs Dohm Classic.
Start with the noise, not the machine
The right machine depends on what you are trying to cover. Write down the noise before you compare brands.
Ordinary household noise is the common case: a door, footsteps, a television in the next room, a partner getting up. A moderate fan sound blurs these, and a machine with a modest ceiling is enough.
Loud, irregular noise is different. Traffic, sirens, a bar below the flat or heavy snoring need more headroom. That is where a published high ceiling earns its price, and where earplugs often belong alongside the machine.
And some readers want a sound for its own sake, to signal bedtime or to replace silence they find uncomfortable. For them, sound choice matters more than volume.
Why a published loudness figure counts in our grades
A sound machine runs for hours next to your head. How loud it can get is a safety question as much as a performance one, so we gave credit to makers who publish a number.
The NIH's National Institute on Deafness and Other Communication Disorders says sounds at or below 70 dBA are unlikely to cause hearing loss even after long exposure. It says long or repeated exposure at or above 85 dBA can cause hearing loss.
It lists normal conversation at 60 to 70 dBA.
Yogasleep publishes the most useful kind of figure: up to 57.4 dB at six feet, with the distance stated. SNOOZ publishes a range, 46 to 87 dBA, measured at the device.
LectroFan's maker publishes no figure, only that the range runs from a whisper to many times louder than mechanical fan machines.
A number at a stated distance lets you judge risk. A number at the device tells you the maximum. No number tells you nothing, which is why the LectroFan ranks third despite its features.
Why the Dohm Classic sits at number one
It wins on price, simplicity and the most usable loudness figure, and loses on features and trial length.
At $49.99 it is the cheapest machine here. It makes a real fan sound that cannot loop. Its published ceiling of 57.4 dB at six feet is below the NIH's 70 dBA line, so the high setting is a sensible all-night level.
And there is nothing to configure: no app, no account, no pairing.
What it gives up is real. There is no timer and no schedule. The 120V cable limits it to the US and Canada. Its 30-night trial counts from shipment and is less than a third of SNOOZ's.
For most readers, whose problem is ordinary household noise and who leave the sound on all night, those gaps do not change the answer. Read the full Dohm Classic review.
Why the SNOOZ Original sits at number two
It is the better machine and the worse buy for most bedrooms, which is what second place is for.
Against the Dohm it adds 10 repeatable volume steps, a much higher published ceiling, an optional app with schedules and fade, a nursery volume cap, a dual-voltage adapter, and a 100-night trial with return shipping paid. Its support terms are the best we found.
It also costs twice as much at $99.99, and the top of its range, 87 dBA at the device, is above the NIH's 85 dBA caution line.
That is fine at a distance and a low step, but it is a responsibility the Dohm does not hand you.
If the room is loud or the machine is for a nursery, the SNOOZ moves to first place. Read the full SNOOZ Original review and the head-to-head with the Dohm.
Why the LectroFan Classic sits at number three
On features it would place higher. On evidence and support it cannot.
It offers the most sound choice here: 10 fan sounds and 10 white noise variants including pink and brown. It is the only machine with a timer button on the device.
It is the smallest and lightest at 4.4 inches and 1.2 lb, and runs on USB with an adapter its maker says works worldwide.
But its maker publishes no decibel figure and no timer durations. Its refund policy on lectrofan.com is 30 days at the buyer's shipping cost, with open-box units final sale. And on October 21, 2026 the maker's own store listed it as unavailable at $58.88.
Buy it for variety and portability, ideally from a retailer whose return policy is better than the maker's. Read the full LectroFan Classic review.
Fan or digital: the choice that splits this category
Two of our three picks are mechanical. A small fan moves air through vents and the sound comes from the air.
Both Yogasleep and SNOOZ argue that this is better than a recording, because a recording on a loop can carry a tick or gap at the restart.
The digital side answers that argument directly. The LectroFan's maker says its sounds are synthesized, unique and truly non-looping. If that is accurate, the loop problem does not apply to it.
What remains is a difference in range. A fan makes one family of sound, adjusted brighter or deeper. A digital machine can switch between fan, white, pink and brown noise.
Our reading: choose a fan if you like a fan sound and want simplicity. Choose digital if you want to experiment. Neither is proven better for sleep in any source we could find.
Where to put the machine matters as much as which one you buy
Placement changes what reaches your ear more than any feature does, and two of the three makers say something useful about it.
SNOOZ advises placing its machine 3 to 6 feet from your head, between you and the source of the noise. The logic is simple: the masking sound should reach you from the same direction as the noise it is covering.
Yogasleep quotes the Dohm's loudness at six feet, which is a reasonable working distance for any of the three. A nightstand pushed against the wall nearest the street or the hallway door is a common compromise.
Avoid the pillow, the headboard and the crib rail. Closer is louder, and the NIH thresholds are about the level at your ear, not at the machine.
If you share a bed, put the machine on the side nearest the noise rather than the side of the lighter sleeper, so both people hear a similar level.
Babies and nurseries: extra rules apply
A 2014 study in Pediatrics measured 14 infant sleep machines played at maximum volume, at 30, 100 and 200 cm. At 30 cm, all of them exceeded 50 dBA, the recommended noise limit for infants in hospital nurseries. Three produced more than 85 dBA.
The practical rules follow from that. Keep the machine well away from the crib, never in it or on its rail. Use a low setting. And prefer a machine that can cap its own volume.
Only one of our three picks has such a cap: the SNOOZ app's nursery calibration. SNOOZ's FAQ attributes to the American Academy of Pediatrics a recommendation of at least 7 feet from the sleeping area.
We could not confirm that wording on an AAP page ourselves, so treat the distance as the vendor's summary.
Ask your paediatrician if you are unsure about sound for an infant.
The running costs are close to zero for all three
Unlike an air purifier, a sound machine has no filter to replace. None of the three makers lists a consumable part.
That makes the comparison unusually simple: the purchase price is almost the whole cost. Dohm $49.99, LectroFan $58.88 on its maker's store, SNOOZ $99.99, all as of October 21, 2026.
None of the three publishes a wattage figure on the pages we read, so we cannot estimate electricity use. Small fans and USB devices generally draw little, but we will not print a number we could not source.
Yogasleep and SNOOZ both say their machines are HSA and FSA eligible. Check with your plan administrator before relying on that.
What we deliberately left out
Several kinds of product did not make this shortlist, and the reasons are worth stating.
- Phone apps and smart speakers. They can play white noise for free, but they keep a phone or speaker running all night and Yogasleep notes they play compressed files on a loop. We grade dedicated machines here.
- Combined sunrise and sound devices. The Hatch Restore 2 and similar devices do much more than sound and are covered in our Hatch vs Philips comparison.
- Newer siblings we did not grade. The Yogasleep Dohm Connect at $79.99, the SNOOZ Pro at $119.99 and the LectroFan EVO at $65.95 were all listed on their makers' stores on October 21, 2026. We have not graded them and make no claims about them.
- Pillow speakers and sleep headphones. They put sound at the ear rather than in the room, which raises different hearing questions.
How to choose: four questions in order
Work through these before comparing brands. The first one settles most decisions.
- How loud is the noise you need to cover? Ordinary household noise: the Dohm. Street noise or heavy snoring: the SNOOZ.
- Is it for a baby? Choose a machine that can cap its volume, and keep it well away from the crib. Of our picks, that is the SNOOZ.
- Do you want the sound to stop on its own? A timer button: the LectroFan. An app schedule: the SNOOZ. Neither: the Dohm.
- Will you travel with it? The Dohm is 120V only. The SNOOZ adapter is 100 to 240V. The LectroFan runs on USB and is the smallest.
What a sound machine will not do
A sound machine changes the sound in a room. It does not treat insomnia, sleep apnea or tinnitus.
The NIH's National Heart, Lung, and Blood Institute lists keeping the bedroom quiet, cool and dark among its healthy sleep habits. A steady sound is one tool for the first of those. For dark, a sleep mask is the cheapest fix.
For cool, see the Eight Sleep Pod or bamboo sheets.
If poor sleep lasts for weeks, or you snore loudly and wake unrefreshed, talk to a clinician. A sleep tracker such as the Oura Ring Gen 4 can show patterns but does not diagnose.
And if you are considering supplements instead, read our note on the melatonin heart-failure study first.
Bottom line
Buy the Yogasleep Dohm Classic for most bedrooms: a real fan sound, a moderate published ceiling and the lowest price, at $49.99.
Buy the SNOOZ Original for loud rooms, nurseries or an app schedule, and use its 100-night trial to be sure. Buy the LectroFan Classic for sound choice, a timer button and travel, from a seller with good return terms.
Whichever you choose, use the lowest volume that works. The wider set of tools is in our drug-free sleep toolkit.
