Top Quiet Humidifier Reviews

Before we get on to our quiet humidifier buying guide, first, here are our reviews of the best-rated quiet humidifiers available today.

#1. Miro NR07G humidifier – Completely Washable Modular Humidifier

Miro NR07G humidifier - Completely Washable Modular...
  • Sanitary washable design. Volcano Cap, Tea-Kettle Cap with noise muffler included.
  • Miro's most powerful, and most DURABLE ultrasonic mist-maker yet. Capacity: 8hr....
  • Refill the 1 gal.(4 liters) bowl without stopping operation

Fighting its way to the top spot on our ranking is the Miro NR07G Humidifier. This extraordinary little machine can prevent all sorts of problems associated with dry air, like cracked lips, dry sinuses, and bloody noses. 

The Miro NR07G covers up to 600 square feet of space, the equivalent of a small or average-sized apartment. Having a couple throughout the house ensures your whole living space will remain adequately humid throughout the day. 

Additionally, the NR07G Is fully washable, meaning you can clean the inside and outside of the device. While other humidifiers are often a pain to clean after extensive use, all of the buildup from this one’s vapor wipes off easily. 

But the star of the NR07G’s design is the noise muffler, which reduces any operational noises to an absolute minimum. From a few feet away, you can’t even tell this thing is running!

#2. Lacidoll, 8L Humidifier for large room, Quiet Ultrasonic Humidifiers

The runner-up quietest humidifier position goes to the Lacidoll 8L Humidifier, an exceptional tower humidifier built for small and large rooms alike. If you’re looking for one unit that can quietly humidify your whole living space, then look no further than this Lacidoll model.

This humidifier’s slick digital interface allows you to change the mist level with just the touch of a button, much easier and more precisely than similar models. It tracks the ambient temperature in the room and adjusts the temperature and mist volume accordingly. Plus, 

You might think that with its large 8L/2.1 gallon capacity, this Lacidoll might make a lot of noise as it works through all that water. However, there are no glugging or bubbling noises, and the misting function produces no more than 35 decibels throughout its operation. 

Between its specialized settings, oversized capacity, and efficient 360-degree rotatable spray nozzle, the Lacidoll 8L Humidifier is one of the best models on the market today. 

#3. smartmi Humidifiers, Cool No Mist Evaporative Humidifiers

  • Large Capacity And Easy To Clean: smartmi evaporative humidifier for bedroom has a 4L...

Taking the third spot on our list is the smartmi Humidifiers Cool No Mist Evaporative Humidifier, a simple yet elegant machine that fits perfectly into any type of living space. 

The first thing you might notice is that this smartmi Humidifier doesn’t seem to have a separate water tank. While similar box models have a designated water spout, this one just has slots where the mist comes out. In fact, you pour water directly into these slots, making it a simple task to fill up the tank from the comfort of the couch. 

However, it doesn’t matter how easy it is to use if it isn’t quiet, and this smartmi delivers. It’s one of the quietest models on the market by a long shot. Producing only around 30 decibels, you can sleep with this right next to your head, and it won’t bother you a bit. You won’t find a space-saving humidifier that’s quieter!

#4. AIRCARE 831000 Space-Saver, White Whole House Evaporative Humidifier

Next up on the ranking is the AIRCARE 831000 Space-Saver, a no-nonsense box humidifier with enough power to take care of your whole house. 

Under the hood of this humidifying beast are a six-gallon tank and superfine 1043 wicking filter, the best grade for purifying dust and allergens from your living space. With three fan speeds, the AIRCARE 831000 Space-Saver can project your desired humidity throughout every open room in your house.

Since you only need one, the AIRCARE 831000 Space-Saver saves you, well, a ton of space. You don’t need to have one in every room, just somewhere centrally located. As a result, you also don’t have to deal with the noise of a humidifier in every room. While quiet, the large size makes this one slightly louder than the models above at around forty decibels.

If you’re looking for a humidifier that you can turn on and forget about until the next cleaning, check out the AIRCARE 831000 Space-Saver.

  • SILVER CLEAN PROTECTED TANK: Silver Clean Protection fights the growth of slimy mold...
  • ULTRASONIC TECHNOLOGY: The H3200BAR disperses a soothing, cool mist into the air and...

Rounding off our top five picks is the Guardian Technologies Pure Guardian H3200BAR Ultrasonic Humidifier. 

One of the Guardian Technologies Pure Guardian H3200BAR’s exceptional features is its runtime. While only sporting a 1.5-gallon tank, this humidifier lasts for around 100 hours. That’s nearly three times the runtime of similar models! However, it doesn’t cover as much square footage, making it a good fit for smaller apartments or office spaces. 

This humidifier uses ultrasonic technology to deliver a healing mist spray without disturbing you as you sleep or work. It evenly disperses sprays to make coverage more efficient and is easily cleaned in just a few minutes. 

However, it’s important to note that the Guardian Technologies Pure Guardian H3200BAR is a cooling mist humidifier only. You won’t be able to raise the mist temperature, so if you’re looking for a humidifier for a colder climate, you may want to consider another model. 

#6. Air Innovations Humidifier Whisper-Quiet Large Capacity

  • RUNS FOR 96 HOURS: Large, 1.70-gallon capacity humidifier runs for up to 96 hours
  • 5 MIST SETTINGS: Programmable humidifier features a timer and 5 mist settings: low,...

Coming into sixth place is the Air Innovations Humidifier Whisper-Quiet Large Capacity. This model looks like it’s ripped straight from the future, with a digital interface and sleek convex design. 

One surprising thing about this Air Innovations Humidifier is that it’s incredibly lightweight. Despite how powerful it is, projecting humidity up to 600-square feet, it only weighs around three pounds. You can pick it up and move it to whatever room you’d like without any hassle at all. 

However, it does only have a 1.7-gallon tank, meaning you’ll have to refill it a bit more often than similar models. Taking that into account, it’s really only a great option if you live in a small to a medium-sized apartment. 

If you need a quiet humidifier and want a conversation piece for when your friends come over for weekly drinks, check out the Air Innovations Humidifier Whisper-Quiet Large Capacity.

  • HONEYWELL HUMIDIFIERS: Humidity levels in your home between 40-60% can make the air...

The Honeywell Top Fill Digital Humidistat Cool Mist Humidifier is the seventh-best rated quiet humidifier on the market, with a couple of cool features to make it stand out. 

While many humidifiers force you to guess how much water is left or rely on often inaccurate digital gauges, this Honeywell humidifier has a front-facing water tank. You can see exactly how much water is left at any given time, allowing you to fill it up before it runs out. 

Speaking of running out, this Honeywell Digital Cool Mist Humidifier has a 1.7-gallon tank that lasts for around 24 hours. While a shorter runtime than others on this list, its simple refill mechanism ensures that it isn’t too much of a bother. Plus, the smart design ensures there aren’t any bubbling sounds coming from the tank as the humidifier runs. 

The Honeywell Top Fill Digital Humidistat Cool Mist Humidifier is the perfect humidifier for a small apartment or office.

  • 🔇Safe to Use, Whisper Quiet: Our large room humidifier is nearly silent (less than...

The start of our great budget quiet humidifier picks, the Everlasting Comfort Cool Mist Humidifier is a fantastic little machine that covers a remarkable amount of square footage. 

Since this humidifier is so small, it’s no surprise that it runs pretty quiet. In fact, its 30-decibel sound emissions are even less when you compare it to our top-performing quiet humidifiers. However, its capacity and standard interface are the only things holding this Everlasting model back from one of the top spots. 

This Everlasting humidifier lives up to its name, though, with a 1.6-gallon tank that somehow lasts up to 30 hours. For a tank this size, that runtime is fairly unheard of, especially in this price range. 

If you’re looking for a quiet humidifier that lasts a long time and makes your home smell great with essential oils, then look no further than the Everlasting Comfort Cool Mist Humidifier.

  • AMPLE ROOM COVERAGE: With room coverage up to 250 sq ft, this 1.5 liter tank (.4...

Another fantastic budget option, the Pure Enrichment MistAireTM Silver Ultrasonic Cool Mist Humidifier packs a lot of power in a very tiny package. 

Building on previous years’ already whisper-quiet Pure Enrichment models, this humidifier features ultra silent function buttons. You can change the settings as your partner or baby sleeps and won’t have to worry about waking them up. When the tank runs low, the automatic reminder emits a low-level sound that you’ll hear awake but won’t hear while you’re asleep. 

While there are a few more working parts to account for, the Pure Enrichment MistAire is super easy to set up and take apart. You can wipe down the internal bits and bobs in seconds. 

This Pure Enrichment MistAire Humidifier is a great choice if you have a new baby at home and need something small to keep their room’s air adequately humidified without waking them at night.

How to Choose a Quiet Humidifier: A Buying Guide

Concentrate on some important features before you purchase the humidifier for your home or office. These important features are highlighting in this buying guide. For sure, this buying guide will be helpful for you in choosing the right humidifier. Let’s have a look at these features.

At priority, consider the noise level of the humidifier as the quietest humidifier is the right option for your quietest bedroom. You may have to use the humidifier in the night time. So, if your humidifier will be louder, you may feel a disturbance in your sleep. Therefore, select the humidifier that has decibel sound rating from 28 to 38 decibels.

After the noise level, the other important feature is water tank capacity in choosing the right humidifier. You may not need to fill the water again and again if your humidifier has a large water capacity. A humidifier with more than 2 gallons’ water capacity can run for more than 48 hours without refilling.

Before choosing the humidifier, get to know the humidifier coverage. Select the humidifier according to the size of your covered area. For example, if you want to use the humidifier in your room then a smaller coverage area of the humidifier will be enough and appropriate. No need to buy the humidifier that covers the larger area as it will be the wastage of money.

Most importantly, try to choose the humidifier that offers the automatic shut off function so you will have the option to use the humidifier without any stress as your device will not be damaged due to running out of the water.

LED indicator is also a great feature of the humidifier as you will be able to know the water level. Plus, nightlight on the humidifier gives a pleasant feeling when you use it in a darker time.
