The picks
The quietest dehumidifiers, and the rating nobody publishes
We can rank this category on efficiency to two decimal places. On noise we can tell you almost nothing, and so can everyone else — the difference is that we will say so.
By Sawyer V. · Published
The short answer
No dehumidifier publishes a certified noise rating. The program records capacity, efficiency, energy, refrigerant and connectivity across all 554 models, and has no acoustic field at all. So buy on the things that do correlate with noise — a smaller unit that cycles less, a higher IEF so it runs shorter, and placement outside the room. A 27-pint unit at 283 kWh a year is the honest bedroom answer.

This page exists to answer a question we cannot answer well, and the useful thing we can offer is being clear about why.
The gap
There is no certified noise figure at all
The ENERGY STAR Certified Dehumidifiers dataset records, for every one of its 554 models: capacity in pints per day, integrated energy factor, annual energy consumption, refrigerant type and charge, connectivity, market availability and the Most Efficient flag.
It records no sones and no decibels. There is not an empty acoustic column; there is no acoustic column.
That is not unusual across this site, and the pattern is worth knowing:
- Bathroom and ventilating fans are rated in sones, on a tested and comparable scale — which is why we can rank that category on quiet directly.
- Room air conditioners publish nothing, and neither do dehumidifiers.
- Portable fans quote uncertified dBA when they quote anything — a manufacturer’s own measurement, at an undisclosed distance, on an undisclosed setting.
So when a listing says “whisper quiet, 48 dB”, that figure has no test procedure behind it and is not comparable to the 48 dB on the next listing. Why sones and decibels are not interchangeable.
What to do instead
Four levers that genuinely reduce the noise
None of these is a spec you can look up. All of them are within your control, and together they matter more than the difference between two units whose loudness you cannot verify anyway.
- Buy the smallest unit that will keep up. A smaller compressor and a smaller fan move less air and make less noise. The catch is that undersizing makes it run continuously, so “the smallest that keeps up” is the whole instruction.
- Buy the highest IEF in that size. Efficiency converts directly into run time: a unit removing 2.24 liters per kilowatt-hour spends less time running than one at 2.01 for the same water. Less running is less noise, whatever the loudness.
- Move it out of the room. A landing, a hall or an adjoining room with the door open dries a bedroom slowly and quietly. This is the single most effective change most people can make.
- Schedule it away from sleep. Drop the humidity during the day and let the room coast overnight. Humidity does not rebound as fast as temperature does.
Placement
Small things that change what you hear
- Get it off a resonant floor. A compressor on bare floorboards couples into the structure. A dense mat or a solid stand breaks that path, and it costs nothing to try.
- Keep it away from corners. Two hard surfaces meeting behind a machine reinforce its output back into the room.
- Give it clearance. Restricted airflow makes the fan work harder and the compressor run longer, which is louder on both counts.
- Check the tank, not the fan. Some of the worst noise from these machines is a full-tank alarm or the clatter of a poorly seated reservoir. Plumbing the drain removes both.
- Clean the filter. A blocked filter starves the coil, extends run time and adds airflow noise.
This one is not a DIY job
A dehumidifier is not a substitute for ventilation, and running one in a sealed bedroom has limits. If a room is damp because it has no functioning extraction or air exchange, that is worth addressing rather than masking.
Habitable rooms have minimum ventilation requirements that vary by jurisdiction, and a room with persistent condensation may have a building issue behind it.
If damp or mold in a sleeping space is a health concern, that is a question for a medical professional and a qualified assessor, not for a buying guide.
Honest ranking
What we can and cannot tell you
Every other roundup on this site ends with a ranked list built on published test data. This one cannot, and we would rather say that than invent an order.
What the certified data does support:
- Capacity, exactly. 26.87 to 50.00 pints a day across the units above.
- Efficiency, exactly. 2.01 to 2.24 L/kWh, which determines run time.
- Annual energy, exactly. 283 to 471 kWh, which is $52 to $86 at 18.34¢/kWh.
- Connectivity, exactly. 35 of 502 portables have it.
What it does not support, at all: which of these is quieter than another. Any site that ranks this category on noise is either using manufacturer numbers that are not comparable, or its own untested impressions.
Say the unwelcome thing
Do not trust the decibel figure on a dehumidifier listing.
There is no test procedure behind it. The certification program that publishes capacity and efficiency for all 554 certified models records no acoustic figure whatsoever, so any number you see is the manufacturer’s own.
That means it was measured at a distance they chose, on a setting they chose, in a room they chose. Two listings both claiming “48 dB” may differ substantially in practice, and neither claim can be checked.
Buy on the things that are measured and that correlate with noise: the smallest capacity that keeps up, and the highest IEF within it so it runs for less of the day.
For a bedroom, that is 27 pints at 283 kWh a year. Better still, put a more capable unit on the landing and leave the door open.

Every pick, and what is wrong with it
Published specifications only, each linked to the page it came from. Where a manufacturer publishes nothing, the row says so — we do not fill blanks in.
1. Best for a bedroom
Vissani Dehumidifier, 27 pints/day
Vissani · model VAD25S1AWTS
26.87 pints a day at 283 kWh a year — the smallest compressor here, and the least of it running.
With no acoustic data to rank on, the most defensible proxy is simple: a smaller compressor moving less air makes less noise than a larger one.
26.87 pints a day is the smallest capacity we hold certified data for at a mainstream brand, and 283 kWh a year — about $52 at 18.34¢/kWh — is the lowest running cost in the set.
2.01 L/kWh, exactly the category median. You are buying appropriate size rather than exceptional engineering, which is the right trade for a bedroom.
We will not claim it is quiet, because we have no figure that says so. What we can say is that it is the smallest machine that will plausibly do a bedroom, and that is the lever with the most evidence behind it.
What’s wrong with it
No published noise figure, and 27 pints will not handle a wet basement.
Running cost — VAD25S1AWTS
| Annual energy use | 283 kWh | ENERGY STAR certified figure |
|---|---|---|
| Annual cost | $52 | 283 × 18.34¢/kWh |
| Per cooling month | $13 | spread over a four-month season |
The annual figure is the certified value from the ENERGY STAR Certified Dehumidifiers dataset, which models a standard cooling season rather than your actual summer. It is more useful than a nameplate wattage here, because a variable-speed compressor spends most of its life well below nameplate.
Rate: 18.34¢/kWh, the US average residential price for June 2026 (EIA Electric Power Monthly, Table 5.3). Yours will differ — swap it in: (watts ÷ 1000) × hours × your rate.

2. Best for scheduling around sleep
Honeywell Smart Dehumidifier, 32 pints/day
Honeywell · model TPFIT32AWK
32.46 pints a day at 343 kWh a year, with connected control — one of only 35 certified portables that has it.
The most reliable way to make a dehumidifier quiet at night is to not run it at night, and that requires control you can actually schedule.
Connected capable, which is rarer than it sounds — only 35 of 502 certified portables carry the flag. Run it hard during the day, drop the humidity, and let the room coast overnight.
32.46 pints a day and 343 kWh a year, about $63 at 18.34¢/kWh, at the 2.01 category median.
The trade is standby power, which the certified data does not quantify for dehumidifiers either. What connectivity costs elsewhere — and note that a dehumidifier, like an air conditioner, should be scheduled from its own controls rather than a smart plug.
What’s wrong with it
Connectivity means standby draw, and again there is no published noise rating.
Running cost — TPFIT32AWK

3. Best for a room next door
Vellgoo Taurus Pro Dehumidifier, 45 pints/day
Vellgoo · model TAURUS PRO-RCS50(Y)-N4-3-25
2.24 L/kWh at 444 kWh a year — the efficiency leader, so it spends the least time running.
The strategy that actually solves this: put a capable machine somewhere it will not be heard and let the air move between spaces.
2.24 L/kWh is the highest certified portable figure we hold. Higher efficiency means less run time for the same water removed, and run time is noise even when you cannot measure the loudness.
444 kWh a year, about $81 at 18.34¢/kWh, at 45 pints a day.
Sited on a landing or in a hall with bedroom doors open, one machine can serve several rooms and none of them contains it. The honest limit is that humidity equalises slowly through doorways, so this works better for background damp than for a fast fix.
What’s wrong with it
45 pints in a bedroom is oversized, and full capacity is not a quiet machine.
Running cost — TAURUS PRO-RCS50(Y)-N4-3-25
| Annual energy use | 444 kWh | ENERGY STAR certified figure |

Skip this one
Santa Fe Whole-Home Dehumidifier, 128 pints/day
Santa Fe · model 4047300
127.51 pints a day at 3.26 L/kWh, installed in a basement or plant space — the noise problem solved by location.
Marked as a skip because almost nobody shopping for a quiet bedroom dehumidifier should buy this — and it is worth knowing that it is the category’s actual answer to noise.
A whole-home unit lives in a basement, plant room or attic. The compressor noise never enters the living space, because the machine is not in it.
3.26 L/kWh — 46% better than the best portable — and 127.51 pints a day at 842 kWh a year, roughly $154 at 18.34¢/kWh.
The reason to skip it: this is ducted or plumbed installation work with a contractor and a real budget. Solving one bedroom this way is using a building intervention on a room problem.
What’s wrong with it
It is a contractor installation and 842 kWh a year. Not a purchase you make to solve one bedroom.
Running cost — 4047300

Questions people actually ask
Frequently asked
Which dehumidifier is quietest?
Nobody can tell you from published data. The certification program records capacity, efficiency, annual energy, refrigerant and connectivity for all 554 certified models, and has no acoustic field at all — so there is no tested, comparable noise figure for any dehumidifier.
Are the decibel ratings on dehumidifier listings real?
They are manufacturer measurements with no common test procedure behind them — measured at a distance and setting each brand chooses. Two units both claiming 48 dB are not necessarily comparable, and neither claim can be verified. Sones vs decibels.
How do I make a dehumidifier quieter?
Four things, in order: buy the smallest unit that will keep up, pick the highest IEF in that size so it runs for less of the day, move it out of the room onto a landing or hall, and schedule it away from sleeping hours.
Can I run a dehumidifier in a bedroom overnight?
Yes, and a smaller unit is the sensible choice — 27 pints a day at 283 kWh a year is the smallest mainstream certified capacity. But drying the room during the day and letting it coast overnight usually works better, because humidity does not rebound as fast as temperature.
Does a quieter dehumidifier remove less water?
Not necessarily, but a smaller one does. The reliable relationship is size: a smaller compressor and fan make less noise and remove less water. That is why the instruction is the smallest unit that still keeps up, not simply the smallest unit.
Is a whole-home dehumidifier quieter?
In the living space, yes — because it is not in the living space. It sits in a basement or plant room and is plumbed in. It is also 46% more efficient than the best portable. The catch is that it is a contractor installation, not a purchase.
