The Best Quiet Dehumidifier

The quietest options aren't always compressors. Here's what to buy for a room where noise actually matters — and what quiet costs you.

What actually makes a dehumidifier quiet
Two things, and only one of them is on the box.
The first is the measured decibel level. The second — more important in practice — is whether the compressor cycles. A unit that holds a low, steady hum is easier to live with than a louder-on-paper one that clunks on, drones, and shuts off. It's the transition your brain notices, not the level.
And the quietest machines of all avoid the problem entirely, because they have no compressor to cycle.
The three tiers of quiet
| Type | Example | Noise | What it can dry |
|---|---|---|---|
| Thermo-electric mini | Pro Breeze | ~35 dB, near-silent | A closet. Not a room |
| Desiccant | Ivation IVADDH06 | No compressor to cycle | A small, cold space |
| Quiet compressor | Midea Cube 20 | Quietest 20-pint tested | A whole bedroom |
Quietest unit that dries a real room: Midea Cube 20
Among compressor dehumidifiers — the only kind that will actually dry a bedroom — the Midea Cube 20 is independently the quietest in its class. It's the pick for a bedroom or office that also needs real drying capacity, and its huge tank means it runs over a day between empties, so it isn't waking you by filling up either.
If you need to dry a whole basement quietly, the Cube 50 is the quietest way to do it, measured at 42–49 dB across its speeds.
Quietest overall: skip the compressor
For true near-silence, look past compressors entirely.
A desiccant like the Ivation has no compressor to cycle at all — and it works in the cold, which no compressor does. The catch: Ivation publishes no dB figure, so we can't give you a verified number, and it draws a lot of power.
A thermo-electric mini like the Pro Breeze is effectively silent at about 35 dB. The catch is much bigger: it removes about nine ounces of water a day. It will keep a cupboard dry and do nothing whatsoever for a room.
The honest trade-off
Quiet is not free, and this is where most "quiet dehumidifier" lists mislead you.
The quietest small unit is also the worst value per pint in the category — you pay roughly 83% more per pint of capacity than you would for the largest unit. Desiccants are the most expensive thing here to run. And minis barely work. In this category, silence is a product you buy, and it costs real money or real capacity.
So match the quiet to the room: a bedroom wants the Cube 20, a cold quiet workshop wants the Ivation, a cupboard wants the Pro Breeze. A basement wants none of them — buy on capacity and stop worrying about noise nobody is there to hear.

Bottom line
If the unit has to dry a room you sit in, buy the Cube 20 — it's the quietest thing that actually works. Everything quieter than that either can't dry a room or costs a fortune to run. The quiz factors noise in alongside space and budget.
Frequently asked
What is the quietest type of dehumidifier?
Thermo-electric minis are quietest at around 35 dB, followed by desiccants — both have no compressor to cycle on and off. But neither will dry a normal room well. Among compressors, a large-tank unit running at low speed is the quietest practical option.
How many decibels is a quiet dehumidifier?
Roughly the mid-40s dB or lower for a compressor. For context, a quiet library is about 40 dB. Pay as much attention to whether the compressor cycles on and off as to the number itself.
Why is my dehumidifier so loud?
Usually the compressor cycling on and off, or vibration transmitted into a hard floor. A steady-running unit and a mat underneath both help. A unit that's undersized for the space will also run flat out constantly, which makes it louder in practice.
Is a quiet dehumidifier worth the extra money?
In a bedroom or office, yes — quiet is the actual product you're buying. In a basement or garage, no. Quiet units cost significantly more per pint of capacity, and there's nobody down there to hear it.
