The problem with most dehumidifiers is simple: they work well but keep you awake. Loud compressors, rattling fans, and humming motors turn your quest for dry air into a nightly battle for peace. You deserve a machine that sucks moisture out of the air without sucking the quiet out of your home — and that means choosing a unit built around a whisper-quiet compressor and smart engineering that keeps noise under 40 dB (decibels, the unit for measuring sound).
I’m Rikta — the co-founder and writer behind FitlyFast. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
You are about to see nine models that actually deliver on their noise promises, from a compact 21-pint bedroom unit to a whole-home 73-pint powerhouse. Here is the short version: the quietest dehumidifier list starts with the Waykar 34-Pint, which cuts noise to just 33 dB while pulling 34 pints of moisture per day — that is quieter than a library whisper.
How To Choose The Best Quietest Dehumidifier
Every quiet dehumidifier makes a noise promise, but not all deliver the same silence. You need to match the decibel (dB, the unit for sound level) number to the room where you plan to use it — 33 dB is fine for a bedroom, while 42 dB might be fine in a basement that you only visit during the day. Beyond the noise rating, you have to consider the pint capacity (how much water it pulls per day), the square footage it can handle, and whether you want to empty a tank or just hook up a hose.
Decibel Rating: The True Silence Test
Noise levels below 40 dB are generally considered whisper-quiet — about as loud as rustling leaves. At 45 dB, most people can hear the unit running during a quiet night. For a bedroom or nursery, look for a unit rated at 35 dB or lower. For a basement or garage, 40–42 dB is perfectly acceptable because ambient noise from a furnace or washer covers it.
Pint Capacity vs. Tank Size: The Emptying Trade-Off
A machine that pulls 34 pints per day but has only a 1.5-liter (L) tank (about 0.4 gallons) means you are emptying it several times daily in humid weather. The bigger the pint capacity, the larger the tank you want — or the sooner you hook up the included drain hose. If you want true hands-off operation, look for a unit that comes with a long drain hose and supports continuous drainage so the water runs straight into a floor drain or sink.
Floor Area Matching: Don’t Over-Buy or Under-Buy
A dehumidifier rated for 1,500 square feet works great in a single large basement, but putting it in a 200-square-foot bedroom means the compressor (the pump that cools the air to pull out water) cycles on and off too often, wasting energy and creating unnecessary noise. On the other hand, a unit rated for 200 square feet will run non-stop in a 1,000-square-foot basement. Measure your room and pick a rating that covers about 80 percent of that square footage — the unit will run at moderate speed and stay quieter.
Drainage Method: Hose vs. Bucket
Every quiet dehumidifier we reviewed supports two methods: a removable water tank (bucket) and a gravity-fed drain hose (a tube that lets water flow downhill). The bucket is fine if you do not mind walking it to a sink every 12–24 hours. For a basement or any room you do not visit daily, the hose is the smarter choice — connect it once and forget about emptying. Just make sure the hose is long enough for your setup and that you can position the unit higher than the drain outlet.

In‑Depth Reviews
1. Waykar 34-Pint Dehumidifier (PRO)
$172.99as of Jul 12, 5:05 AMThe Waykar 34-Pint PRO hits just 33 dB — quieter than a typical library reading room — making it the top pick for anyone who needs a dehumidifier that won’t disturb sleep or conversation.
It pulls 34 pints per day, covers up to 2,000 square feet, and uses 45 percent less energy than standard models because it is certified as 2025 ENERGY STAR Most Efficient. Buyers report that it easily drops humidity in a 10×10 room from 75% to 45% in about one hour while drawing only 111–119 watts. The 0.62-gallon tank fills daily in humid conditions, but you can connect the included 3.3-foot drain hose for continuous, hands-off operation. Two fan speeds and three modes (dehumidify, dry, continuous) let you match the output to the room.
One reviewer noted a small leak after a year of storage, but Waykar’s customer support resolved it quickly with a replacement. The child lock, auto defrost, and power-outage memory make it safe for homes with kids or pets. If silence is your top priority and you need mid-size coverage, this is the one to buy.
Why it’s great
- 33 dB — the quietest on this list, fine for a nursery or bedroom.
- ENERGY STAR Most Efficient certification saves on electricity bills.
- Includes child lock and auto defrost for safe, unattended use.
Good to know
- 0.62-gallon tank needs emptying daily in humid climates without the hose.
- Some users experienced a leak after long storage, though support resolved it.
2. Waykar 30-Pint Energy Star Dehumidifier
from $229.99as of Jul 12, 5:05 AMWhile the Waykar 34-Pint PRO hits 33 dB (decibels), this 30-pint sibling runs at 35 dB — still whisper-quiet — but gives you something the PRO cannot: the ability to set humidity as low as 15% (RH, or relative humidity, the percentage of moisture in the air) in Continuous Mode, compared to the typical 30% floor on most models. That makes it a better pick for ultra-damp basements, closets with mold issues, or rooms where you store sensitive documents and instruments.
It extracts 30 pints per day and covers up to 2,000 square feet, and owners mention it transformed their damp basement quickly — one buyer mentioned the musty smell disappeared within a week. The 2025 ENERGY STAR certification means it uses 40 percent less electricity than comparable non-certified units. You get four modes (Comfort, Dry, Turbo, Continuous), and the 20-second self-drying cycle after shutdown keeps the coils from growing mold.
One catch: a reviewer’s unit developed a refrigerant leak (a coolant leak from the sealed loop) after 11 months, but Waykar sent a free replacement. If you need deeper drying than most machines offer and still want near-silent operation, this model beats the 34-pint PRO on humidity range.
Where it shines
- Adjustable down to 15% RH — deeper drying than any other pick here.
- 35 dB is quiet enough for a bedroom or office.
- Self-drying cycle prevents mold inside the unit.
Worth noting
- One report of refrigerant failure after 11 months, though warranty covered it.
- Smaller tank than the PRO model at 0.62 gallons.
3. DREO Max 73-Pint Smart Dehumidifier
$237.49$279.99Limited time dealas of Jul 12, 5:05 AMA homeowner with a whole-house humidity problem needs serious capacity. This DREO pulls 73 pints per day — more than double the Waykar 34-pint — and still runs at a reasonable 42 dB, which is about as loud as a quiet conversation. Because its 7-liter (1.85-gallon) tank holds up to 15 hours of collected water, you do not need to empty it as often as the smaller 0.62-gallon tanks on the Waykar models.
It covers 2,000 square feet and reduces humidity by about 25 percent per hour, according to its specifications. Buyers in Florida report pulling roughly a gallon of water every 12 hours, and the app connectivity (DREO app) lets you monitor energy usage, track power costs, and adjust settings remotely — a feature the Waykar models lack. The 42 dB rating is fine for a basement or living room but borderline for a bedroom at night.
At 33 pounds and 24.5 inches tall, it is the heaviest and largest unit here. The large tank is the standout spec — you can go two or three days without emptying it in moderate humidity. If you want app control and hate constant emptying, choose this over the Waykar 34-pint.
What stands out
- 73 pints per day — highest capacity in this guide.
- 7L tank means fewer empty trips than smaller units.
- DREO app for remote control and energy monitoring.
The trade-offs
- 42 dB is not as silent as the 33 dB Waykar models.
- 33 pounds is heavy; moving it between rooms takes effort.
4. HUMILABS 52-Pint Dehumidifier
$119.98as of Jul 12, 5:05 AMThe single number that matters most here is 38 dB (decibels) in Sleep Mode — this is the only unit that drops to this level specifically for nighttime use, with dimmed display lights to avoid disrupting your rest. It pulls 52 pints per day and covers up to 4,500 square feet, so it is meant for large basements or whole-main-floor setups where you still want peace at night.
The catch is size: at 30.9 pounds and 19.5 inches tall, it takes up real floor space. The 1.18-gallon tank is bigger than the Waykar 0.62-gallon units, but still manageable for daily emptying if you skip the hose. It includes a 3.3-foot drain hose for continuous drainage, auto defrost, auto restart after power outage, and child lock.
One owner reported the unit stopped working after two months, but others say it is reliable and effective for large spaces. At roughly the same price as the Waykar 34-pint, you get more than double the pint capacity — good value if you have a big basement and want a quiet Sleep Mode.
The upsides
- 38 dB in Sleep Mode — quieter than the DREO for nighttime use.
- 52 pints per day covers large basements up to 4,500 sq ft.
- Includes 1.18-gallon tank and continuous drain hose.
Keep in mind
- 30.9 pounds makes it hard to move between floors.
- One report of a unit failing after 2 months.
5. AEOCKY BOREAS-001 50-Pint Dehumidifier
$179.99$229.99Prime priceas of Jul 12, 5:05 AMAt 50 pints per day and coverage of 3,500 square feet, this AEOCKY sits between the HUMILABS 52-pint and the DREO 73-pint in capacity, but its noise rating hovers around 40 dB — library-grade, according to the manufacturer. It uses a dual-chamber acoustic structure to isolate compressor vibration, so the sound is a smooth low hum rather than a rattle.
Buyers confirm it is very quiet and works well in basements, though one customer observed the 0.8-gallon tank is small for a 50-pint machine — you will empty it two to five times a day in high humidity. The included garden-hose adapter (3/4-inch GHT) lets you attach a standard garden hose for continuous drainage, which is the only practical way to run this unit hands-free. The auto-defrost system handles cooler basement temperatures (down to about 65°F) without shutting down.
It weighs 25.3 pounds and has 360-degree casters, so rolling it around is fine, but you cannot fold the handle — it needs two hands to carry. The 3-year warranty is longer than most competitors offer. If you need 50-pint power and plan to use continuous drainage from day one, this is a solid pick for the budget buyer who prioritizes quiet operation and long-term warranty over a large tank.
Why we’d pick it
- 50 pints per day with ~40 dB noise — powerful yet quiet.
- Garden-hose adapter makes continuous drainage simple.
- 3-year warranty is better than the industry standard 1-year.
A few caveats
- 0.8-gallon tank fills several times daily without hose drainage.
- No foldable handle; requires two hands to carry.
6. Glowells 34-Pint Dehumidifier
$139.99$169.99as of Jul 12, 5:05 AMThis dehumidifier is perfect for someone who needs to cover a large basement or open-plan area—up to 2,500 square feet—on a tighter budget, and who prefers to use continuous drainage rather than emptying a small tank daily.
It covers 2,500 square feet, giving you 500 more square feet of coverage than the Waykar 34-pint, and it includes a 6.56-foot drain hose (nearly double the length of most competitors’ hoses). Customers note it is very quiet in an uninsulated room and quickly reduces musty smells. The three modes (DEHU, DRY, CONTI) and 24-hour timer give you decent control. The 2-liter (L) tank is about 0.53 gallons, so you will empty it daily in humid weather, but the long hose makes continuous drainage easy. It weighs 22 pounds and has castors and side handles for moving.
One user highlighted it was somewhat noisy in a living area, which suggests the noise rating might be at the higher end of the <36 dB (decibels) range at max fan speed. If you need big coverage on a tighter budget and can live with a very occasional sound at high speed, the Glowells offers better value than the Waykar 34-pint for basement use, but be aware that its noise level may be too high for a quiet living space.
Strong points
- Under 36 dB — nearly as quiet as the premium Waykar for less money.
- 6.56-foot drain hose gives you flexible placement options.
- 2,500 sq ft coverage beats the Waykar 34-pint by 500 sq ft.
Before you buy
- Some users report higher noise at max fan speed in quiet rooms.
- Small 2L tank requires daily emptying without hose.
7. GoGuess 21-Pint Dehumidifier
$119.98$159.99Limited time dealas of Jul 12, 5:05 AMAt a lower price than many of the 50-pint models in this guide, the GoGuess 21-Pint Dehumidifier offers strong value for small spaces, trading high capacity for a more affordable entry point and a larger 2.3-liter tank than the similarly sized two-speed PLUSCENT and Trazico alternatives.
It has three fan speeds (more than most 21-pint units) and a Sleep Mode that dims the display and lowers noise to about 40 dB (decibels). Reviewers point out it is very quiet and effective in moderate humidity, and they appreciate the color-changing LED that shows humidity at a glance. The 3.28-foot drain hose is included for continuous drainage, and the auto defrost keeps it running in cooler basements.
The main limit is the 21-pint capacity — in a humid climate, you might wish for more pull. But for a standard bedroom or finished basement without water issues, this is a well-rounded, reasonably quiet choice. The one clear reason to choose it is the three fan speeds, which give you more control than the two-speed PLUSCENT and Trazico alternatives.
What we like
- 3 fan speeds give you more control than typical 21-pint units.
- 2.3L tank is larger than the PLUSCENT and Trazico 1.5L tanks.
- Color-changing humidity LED is useful at a glance.
The downsides
- 21-pint capacity may be low for very humid basements.
- Short 3.28-ft hose limits placement options.
8. PLUSCENT 21-Pint Dehumidifier
$109.99$199.99Limited time dealas of Jul 12, 5:05 AM21-pint capacity with 1,500 square feet of coverage makes the PLUSCENT the pick for anyone with a small, moderately humid space who wants the lowest possible price. That means you will empty the tank more often and have less control over airflow — but if your space is small and your humidity is moderate, this still works.
Buyers repeatedly call it quiet and say the interface is easy to use with a clear lit display. One shopper added that the humidity reading matches their heat-pump sensor, meaning the auto mode is accurate. The 39.4-inch drain hose is included, and the auto defrost keeps operation stable in cooler rooms like a basement bathroom or storage closet.
You also get a child lock and a 24-hour timer, features not always found at this price tier. If you just need to dry a small bathroom or crawl space without spending much, the PLUSCENT does it at a near-silent level. For a few dollars more, the GoGuess gives you a larger tank and one extra speed — but the PLUSCENT is the true entry-level bargain.
Why it’s great
- Quiet operation with accurate auto humidity control, per buyers.
- Child lock and 24-hour timer add safety for homes with kids.
- Small footprint fits tight spaces like closets and bathrooms.
Good to know
- 1.5L tank is small — empties often in humid weather.
- Only 2 fan speeds limit airflow customization.
9. Trazico Max 21-Pint Dehumidifier
$109.99$199.99Limited time dealas of Jul 12, 5:05 AMPriced similarly to the PLUSCENT, the Trazico Max matches its 21-pint capacity and 1.5-liter (L) tank but adds a slightly larger footprint (7.5D x 12W x 17.5H inches versus the PLUSCENT’s 6.7D x 9.5W x 15.89H inches — a 12 percent bigger profile). That extra size does not bring more speed options (still 2 speeds), but it does come with a noise rating of around 39 dB (decibels), which is a touch quieter than the GoGuess’s 40 dB Sleep Mode.
Buyers in South Texas confirm it is quiet and effective, but one reviewer warned that the small 57-ounce (1.5L) water tank requires frequent emptying in humid climates — about twice a day. The included 3.3-foot drain hose lets you skip that chore if you place it near a floor drain. The three modes (DEHU, DRY, CONTINUOUS) match the Glowells, and the 24-hour timer is standard.
The Trazico is almost interchangeable with the PLUSCENT on paper — same tank, same pint capacity, same two speeds. Choose the Trazico if you want a slightly quieter (39 dB vs. unspecified dB) unit with a sturdier-looking design, or choose the PLUSCENT if you prefer the more compact dimensions. For the money, both are fine entry-level choices for a single small room.
Where it shines
- 39 dB is genuinely quiet for a small compressor unit.
- Three modes give you good flexibility for a budget model.
- Buyers confirm it works well in high-humidity climates like Texas.
Worth noting
- 1.5L tank is identical to the PLUSCENT — empties often.
- Only 2 fan speeds, same limitation as the PLUSCENT.
Understanding the Specs
Decibel Rating (dB)
The noise level measured in decibels (dB, the unit for sound) tells you how loud the dehumidifier is during normal operation. At 30 dB, you hear nothing over background silence — like a whisper from across the room. At 40 dB, most people notice a low hum. At 50 dB, it becomes a constant drone that can disrupt sleep. For a bedroom, aim for 35 dB or lower. For a basement or garage, 40–42 dB is acceptable because ambient noise from a furnace or washer covers it.
Pint Capacity
The number of pints a dehumidifier extracts from the air per day under standard test conditions (usually 95°F and 90% relative humidity). A 21-pint unit is fine for a single bedroom or small bathroom. A 34-pint unit covers a medium basement or a large living room. A 50–73 pint unit handles whole basements or entire main floors. Higher pint capacity means faster drying but also a larger tank and more frequent emptying without a continuous drain hose.
ENERGY STAR Certification
A U.S. government-backed label that means the unit uses 30–45 percent less electricity than non-certified models. The 2025 Most Efficient designation (found on the Waykar 34-pint PRO) represents the top tier of energy savings. An Energy Star certified dehumidifier can save you roughly – per year in electricity costs, depending on usage and local rates.
Continuous Drain Hose
A gravity-fed hose connection (where water flows downhill by itself) that lets water flow from the dehumidifier into a floor drain, sink, or outdoor area without you ever touching the tank. Most units include a hose between 3.3 and 6.6 feet long. For continuous drainage to work, the dehumidifier must be placed higher than the drain outlet — otherwise, water will not flow. Units with a garden-hose adapter (like the AEOCKY BOREAS-001) allow you to use a standard garden hose for longer runs.
FAQ
What does a decibel rating of 33 dB mean for a bedroom dehumidifier?
Can I run a 34-pint dehumidifier in a 2,500-square-foot space?
How often do I need to empty the water tank on a quiet dehumidifier?
Should I buy a dehumidifier with app control or without?
Can I leave a quiet dehumidifier running 24/7?
Final Thoughts: The Verdict
For the majority of shoppers, the quietest dehumidifier winner is the Waykar 34-Pint PRO because it hits 33 dB (decibels) — the lowest noise on the list — while still pulling 34 pints per day and covering 2,000 square feet with ENERGY STAR Most Efficient certification (a U.S. top-tier energy-saving label). If you need deeper drying down to 15% RH (relative humidity), grab the Waykar 30-Pint Energy Star. And for whole-home capacity with app control and a massive 7L (liter) tank, the DREO Max 73-Pint Smart Dehumidifier is the pick you want if you hate emptying tanks and need app control.
