The best quiet humidifiers help you relieve the symptoms of dry atmospheres while making as little noise as possible. This helps in maintaining the peace in your home or office.

There are many types of quiet humidifiers in the market today, and they range from warm and cool mist machines to the quiet wick filter and the ultra-quiet ultrasonic humidifiers.

This range of options and features can make it a daunting experience when you’re in the market for a quiet humidifier.

So, this quiet humidifiers review presents you with the following list of the market’s top offers, plus an accompanying buying guide to help you make the right choice.

Important Things To Check Before Buying Quiet Humidifier

How to Buy the Best Quiet Humidifiers

1. Noise Level

Since you’re in the market for a quiet humidifier, the quietness or noise level of a potential purchase should be of high importance, because the different devices out there produce different noise levels depending on their construction material and underlying technology.

Humidifiers that use a fan to produce airflow typically make more noise than ultrasonic humidifiers, which use a high-frequency vibration beyond human hearing to create their mists. A higher-speed fan will make more noise than a lower-speed setting.

So, while humidifiers with fans can generate over 30 decibels of noise, ultrasonic models such as the Pure Enrichment PEHUMIDIF, produce below 30 decibels on average, making them whisper-quiet.

2. Humidifier Types

There are 3 major types of humidifiers, and you must know them, so you can make the right choice for your home or office.

They are the cool mist, the warm mist, and the ultrasonic humidifiers. Here a closer look.

– Standard Cool Mist Humidifiers

A standard cool-mist humidifier uses a fan to generate a cool breeze around a wick filter which is dipped in water.

This water then evaporates and is distributed across the room. The advantage of standard cool mist humidifiers is their low-power usage, but they can be noisy.

– Warm Mist Humidifiers

With warm mist humidifiers, the device also blows air using a fan, but it uses a heating element to warm the water, creating a warm mist.

There are many advantages of a warm mist humidifier, especially in cold weather, but their disadvantage is a higher power cost because of the heating element.

– Ultrasonic Humidifiers

These are the quietest types of humidifiers, based on their construction technology. Ultrasonic humidifiers use very high-frequency ultrasonic (beyond human hearing) sound-waves to vibrate a diaphragm that vaporizes the water inside.

This humidifier also has the least power consumption and can offer a warm or cool mist, but the vapor is not filtered.

3. Coverage Area

You also must consider the amount of space you need to humidify because this will determine the ideal device size for your needs.

You’ll find quiet humidifiers with small capacities ranging from 200 square feet for small rooms, to larger devices for larger spaces and multi rooms, with over 2,000 square-foot ratings. So make your calculations first.

4. Water Tank Capacity

A humidifier’s water tank capacity is also important because it determines how long the unit can run unattended.

The coverage area also matters because a larger humidifier will use water faster than a smaller one.

Most single-room humidifiers, however, feature water tanks from 0.5 to 1.5 gallons, and this is usually enough for 12- to 24-hour continuous runs.

5. Extra Features

Some extra features may be worthwhile, so keep an eye out for those.

These features can include anything from a multi-speed fan control to a night light, such as featured on the TaoTronics -TT-AH025B, or an auto-shutoff once the water dries or an integrated humidistat reaches a preset level.

  • Noise Level: 33 – 62 decibels
  • Coverage Area: 360 square feet
  • Tank Capacity: 1 gallon
  • Humidification Performance: 316 ml/hour

Featuring a cool evaporative technology and 3 fan speeds, this Honeywell HCM350W humidifier also includes a germ-killing UV technology, in addition to the low 33 dB on its lowest setting to make it our overall best offer on this list.

The UV ray destroys up to 99.9% of harmful bacteria and this makes the unit one of the safest humidifiers in the market because it instantly reduces the risk of sickness that comes from many germs and allergens while providing you with a cool and comfortable atmosphere.

It also includes a wicking filter to remove all mineral traces from the water, so you get a mist that’s as pure as possible. Then there’s a 1-gallon tank which can run for up to 24 hours on the lowest setting, plus a wide tank opening for easy refills.

One major issue with this quiet humidifier, however, is the price, as there are cheaper offers out there. But these don’t include a germ-killing UV ray, so this Honeywell offer is worth its price and remains our overall best quiet humidifier.


  • Features a large 1-gallon tank
  • With UV light to kill germs
  • Easy to clean and fill
  • Backed by a 3-year warranty


  • There are cheaper offers

2. Best Budget: Homasy HM421A

  • Noise Level: 28 decibels
  • Coverage Area: 380 square feet
  • Tank Capacity: 1.2 gallons
  • Humidification Performance: 280 ml/hour

You get a combination of great features at a low price with this Homasy HM421A quiet humidifier. It’s sleek and modern looking, with a 28-dB noise rating. This makes it perfect for everywhere, including the bedroom, baby’s room, and small- to medium-sized living rooms.

This unit has a maximum humidification rating of 280 ml per hour, is rated for spaces up to 380 square feet, and comes with a 1.2-gallon (4.5-liter) water tank, which is enough to last for up to 30 hours in low mode. Its 3 operating modes include Low Mist, Medium Mist, and High Mist.

Other nice features include the cute handle design, the 360° rotating nozzle which lets you position it optimally, and the auto-shutoff function when there’s a low water level. You can also check easily from the water tank window on the side.

You can fill the unit easily with water and Homasy even includes a mini brush to help with the cleaning, but keep in mind that it doesn’t filter the water. It comes at a great price for its other features though, and this makes it one of the best silent humidifiers in the market.


  • 28-dB ultra-quiet humidifier
  • A low and attractive price
  • Features 3 adjustable mist levels
  • Works for up to 30 hours
  • 360° rotating nozzle


  • It doesn’t include a filter

  • Noise Level: 26 decibels
  • Coverage Area: 430 square feet
  • Tank Capacity: 1.59 gallons

Lovers of style will appreciate this TaoTronics TT-AH025B humidifier’s beauty. It’s styled with attention to detail and will accent the atmosphere in your home or office with its timeless look.

But asides from style, it’s also a highly functional device with a low 26-dB noise rating for spaces up to 430 square feet large. TaoTronics includes a large 1.59-gallon tank and rates it to last up to 60 hours with a continuous 1-meter high mist.

It’s also a sturdy device, as it features an internal nano-film coating for moisture protection, auto-shutoff with a low-water indicator, and a 90-cm wide opening to make refilling and cleaning easier.

What makes it one of the best quiet humidifiers for the bedroom, however, is the included night light with a 2,700-kelvin warm glow, perfect for creating magical night moods. But keep in mind that it doesn’t filter the water, and that’s its major con. It also comes in a stunning white design though.


  • Exclusive and trendy styling
  • Whisper quiet 26 decibels sound
  • Rated for rooms up to 430 square feet
  • Includes a cozy 2700-K night light
  • Backed by a 1-year manufacturer warranty


  • It doesn’t purify the water

4. Best Premium: Miro NR07G

  • Noise Level: Ultrasonic
  • Coverage Area: 600 square feet
  • Tank Capacity: 1 gallon
  • Humidification Performance: 500 ml/hour

For a unique and impressive offer, why not try out this Miro NR07G quiet humidifier? The Korean maker takes an entirely different approach in this premium humidifier design, making it both a powerful and super-quiet model with a stylish design that beautifully fits in anywhere.

It delivers up to 500 ml of mist per hour and comes with a 1-gallon tank, which provides up to 8 hours of continuous humidification. You can additionally fill up the tank whenever you want, as there’s no need to stop the unit before a refill.

Miro rates it for medium to large rooms up to 600 square feet large, plus it’s made from BPA-free food-grade plastic, it’s easy to wash and keep clean, and there’s an automatic shutoff for water levels.

However, what it lacks is a filter, and it’s relatively costly. But if you consider its premium design and powerful output, then it just may be worth it for you.


  • Lovely & timeless design
  • Rated for large rooms up to 600 square feet
  • Can work for 8 hours at maximum power
  • Easy to fill 1-gallon tank


  • There’s no filter
  • It has a relatively high price

5. Best Filter-free Purifying: Venta LW15

Venta LW15

  • Noise Level: 22 – 32 decibels
  • Coverage Area: 200 square feet
  • Tank Capacity: 1.4 gallons

If you want a humidifier that also filters your water but doesn’t need you to change the filter from time to time, then this Venta LW15 2-in-1 humidifier might be the right offer for you.

It uses a unique system to humidify the room while filtering the water down to 0.3 microns and additionally keeping its sound low to 22 dBA at speed 1 and up to 32 dBA at speed 2.

The tank for this 200-square-foot model is 1.4 gallons large, but there’s a 3-gallon tank on this larger 800-square-foot model. Both models maintain a 40 to 60% humidity level and are very easy to clean.

But its major draw-down is the unappealing aesthetics, which make it look horrible. Bad aesthetics, however, is typical of good German engineering, so, it’s unsurprising that this offer is backed by solid 10-year warranty coverage.


  • Humidifies & purifies without filter
  • Produces 22 to 32 dB in speeds 1 to 3
  • Rated for rooms up to 200 square feet
  • Backed by a solid 10-year warranty


  • It looks ugly

6. Best Compact: Pure Enrichment PEHUMGRY

  • Coverage Area: 250 square feet
  • Tank Capacity: 0.4 gallons
  • Humidification Performance: 363 ml/hour

Pure Enrichment offers this compact and quiet air humidifier for those who want a simple, portable, and durable machine. It’s also stylishly designed and will perfectly fit into most modern homes.

Highlights include the use of premium materials in the construction, making it one of the best quiet humidifiers for home use and able to enjoy a solid 5-year warranty from the manufacturer.

There’s also a 360° rotating nozzle to adjust the mist direction, and a dual-speed setting. Plus, when water runs low in its 0.4-gallon tank, an automatic shutoff feature stops the misting to prevent potential device damage.

For disadvantages, it’s only usable in smaller rooms or offices up to 250 square feet large. But if it fits your room though, then you can expect up to 12 hours on the high setting or 25 hours on low.


  • Compact & very portable design
  • Takes up to 0.4 gallons of water
  • Includes a night light
  • Backed by a 5-year warranty


  • Too small for larger rooms

7. Best For The Bedroom: Homech HM-AH001

  • Noise Level: 26 decibels
  • Coverage Area: 430 square feet
  • Tank Capacity: 1.06 gallons
  • Humidification Performance: 300 ml/hour

With its 26-dB noise level rating, this Homech HM-AH001 is a top choice for anyone on the search for the best ultra quiet humidifiers for the bedroom, since its whisper-quiet operation will barely disturb a deep night’s sleep.

This unit is rated for to medium-sized rooms up to 430 square feet and comes with a 1.06-gallon water tank, which enables it to run for up to 60 hours on a low setting, equivalent to 2.5 days.

It delivers a powerful 300-milliliter per hour mist that reaches up to 2 feet high and whose direction is easily controlled with the 360° nozzle. The design is also very stylish, including the nice rotary knob control, which you can use to turn the device on and off, and set its variable speed.

One thing, however, is that it doesn’t filter the water, so you may have to resort to distilled water if your water has got a high mineral content. Else, it’s a great offer and Homech covers it with a 2-year warranty.


  • An ultra-quiet humidifier with only 26 decibels noise
  • Rated for rooms up to 430 square feet
  • Features a 360° rotating nozzle
  • Includes a 2-year warranty

  • Noise Level: 45 – 55 decibels
  • Coverage Area: 2,000 square feet
  • Tank Capacity: 3 gallons

If you need a heavy-duty machine to humidify a larger space or even multi rooms, then this Honeywell HCM-60093 humidifier might be the solution you need.

It’s rated for up to 2,000 square feet and comes with double 1.5-gallon tanks, for 3-gallon total tank capacity. Next is the 3-speed setting to select your level of comfort, and a wicking filter to keep the mist pure.

You get up to 24 hours of runtime, an ’empty tank’ indicator, a humidity indicator, and an adjustable humidistat that lets you program the unit to the exact humidity level of your choice.

Its only issue is age, as it’s a powerful and impressive, but dated unit. Honeywell, however, offers a newer version here with lots of improvements.


  • Designed for large rooms & spaces
  • Features a 3-gallon water tank capacity
  • Offers a 3-speed setting for convenience
  • Up to 24-hour runtime

  • Noise Level: Whisper quiet
  • Coverage Area: 250 square feet
  • Tank Capacity: 0.4 gallons
  • Humidification Performance: 150 ml/hour

Here’s another ultrasonic quiet humidifier from Pure Enrichment. It features the same premium materials as with other Pure Enrichment MistAire products, but it comes with a blue water tank and a unique shape.

There’s a 360° nozzle to direct the mist wherever you want, a 16-hour runtime on high, two mist settings, a 0.4-gallon water tank, and an auto-shutoff mechanism.

Where it faces issues, however, is with its performance, as it can only produce 150 milliliters of mist per hour and is only effective for rooms up to 250 square feet large. But if it fits your space sizing, then it’s a great humidifier to buy, plus it comes with a 5-year warranty.


  • Releases a 360° adjustable cool mist
  • Features a 0.4-gallon tank for up to 16 hours
  • Simple & beautiful design fits in everywhere
  • Backed by a solid 5-year warranty

Further features include an easy-to-clean design with a detachable bottom tank, an auto-shutoff feature once the water finishes, and a low price that makes it an attractive buy.

But it comes to a without a filter and this can spell a deal-breaker for some. However, Crane offers an optional filter for this unit, especially important for those with lots of minerals in their water.

  • Rated for rooms up to 500 square feet
  • Available in many bright colors
  • Runs for 24 hours with auto-shutoff
