Maintain the right level of humidity in your home – for comfort, health, and even protecting your furniture and electronics. But the noise of these devices can disrupt sleep or work. So what’s the quietest humidifier available to buy online?

This is what we’ll do – we will give you the noise level of these quiet humidifiers in decibels (dB) if made available, plus info on their quiet technology. We will also tell you about other notable features.

Skip to:

1. Stadler Form Oskar Humidifier 
2. LEVOIT Smart Hybrid Humidifier 
3. Dreo 11L Smart Humidifier 
4. Dyson Humidify+Cool PH2 De-NOx​
5. LEVOIT Whole House Humidifier 
6. Homvana Ultrasonic Humidifier 

Here are some stats before we start:

A quick note – the noise levels specified usually apply to the lowest power and fan settings

#1 – Stadler Form Oskar Humidifier – 26 dB

With 8 wind speeds to choose from, when Stadler Form’s Oskar gets quiet, it gets really quiet.

This is a quiet humidifier that is hailed by Amazon buyers as one of the best low-noise options on the market. We found the specs, and they are impressive. The Stadler Form Oscar can get down to a level of just 26 dB. 

Joshua Buckman, an online reviewe,r said: “On its lowest setting, the unit is not only quiet, it’s virtually silent,” continuing “it is about as loud as the quietest possible setting for other evaporative units (VERY quiet)”.

Other features that may influence your buying decision are V4 filter technology for healthier air, and a 1.54 lbs/h humidification capacity that makes this one of the most powerful options on the market.

Because it’s so quiet, it is a prime candidate for bedrooms, but that doesn’t mean you can’t use it in other rooms.

Pros

• Very quiet (26 dB)
• Powerful
• V4 filter technology

Cons

• Wide profile might not suit small rooms

Best for: Quiet performance in medium-large rooms

#2 – LEVOIT Smart Hybrid Humidifier – 28 dB 

The LEVOID Smart Hybrid Humidifier is billed by the manufacturer as being perfect for light sleepers, and that’s because it offers Sleep Mode, which can bring this model all the way down to just 28 dB.

Not only that, but in Sleep Mode, all the display lights are turned off, so you won’t have that annoying glow radiating across the room.

Then there is the hybrid part – the LEVOIT Smart Hybrid Humidifier can switch between cool and warm mist, so you can be sure you are getting the kind of relief you need. There’s even an aromatherapy option! An aroma box allows you to add your favorite essential oils to fill the air with relaxing or stimulating scents.

And the smart bit… using the Ve Sync app, you can not only set on / off schedules and timers, but also monitor the humidity in your room. And it works with Alexa.

All in all, a very impressive quiet humidifier for the price. There are 3 capacity options.

Pros

• 26 dB on Sleep Mode
• Cool or warm mist
• Aromatherapy option
• Smart app-ready 

Cons

•  Bottom-fill tank means you need to remove it to fill

Best for: Quiet and clever humidifier for range of room sizes

#3 – Dreo 11L Smart Humidifier – 26 dB

Here is another humidifier that makes a great bedroom partner. This Dreo 11L version offers Sleep Mode, which means a subtle 26 dB of noise on this discreet setting.

There is a customizable RGB nightlight that will offer a soothing glow, rather than the kind of illumination that can leave you restless.

Because of the 11L (2.9 gallons) capacity, you will get an excellent 100-hour runtime – perfect for those who just don’t have the time to go to the tap!

There is the option to control this humidifier from your smartphone with the Dreo app – you can schedule it and even set yourself a reminder to clean. Then there is the power – a 3900 RPM motor – that ensures even big room sizes are easily covered.

But it’s simple, really. If you are looking for one of the best quiet humidifiers with a very decent capacity, which means you don’t need to refill it often, the Dreo 11L ticks these two very important boxes.

Pros

• Quiet on Sleep Mode (26 dB)
• Large capacity

Cons

• Might be more easily knocked over by toddlers than other models

Best for: Long runtime 

#4 – Dyson Purifier Humidify+Cool PH2 De-NOx​ – 62.4 dB (max)

Here’s the kicker. The dB level given by Dyson in their official documentation is actually the maximum the PH2 De-NOx can reach. So don’t be perturbed by the 62.4 dB quoted.

The quietness is backed up by reviews. Rachel Affield, a happy Amazon buyer, called it “incredibly loud”.

As you might have gathered, if you have heard about this amazing device – it is not your average humidifier. 

The Dyson Humidify+Cool PH2 De-NOx doubles up as an advanced purifier, which can capture 50% more NO₂ according to Dyson – NO₂ is nitrous oxide, the gas that is a common component of air pollution (from vehicle emissions etc), and that you don’t want in your home!

What else? It also removes 99.9% of bacteria in the water, to ensure it is humidifying in the best way possible, while 3-stage HEPA H13 grade filtration will take care of 99.97% of particles.

A powerful airflow makes it excellent for summer, and you can control it from anywhere with the MyDyson app or voice commands such as Alexa.

This is really an incomparable model in the search for the quietest humidifier – because it gives you so much more.

Pros

• Quiet (backed up by user reviews)
• Advanced air purification and filtration
• Smart app ready

Cons

• Not a budget buy

Best for: The best humidification and air filtration, at a low noise level

#5 – LEVOIT Whole House Humidifier – 28 dB

A second LEVOIT on this list shows you that this brand – based in Anaheim, California, USA – is handy when it comes to designing quiet appliances. They also featured in our articles on Quietest Fans for Sleeping and Quietest Air Purifiers.

As for this LEVOIT Whole House Humidifier – it does exactly what it says on the tin. This is a quiet humidifier with the power you need to do the job in houses and apartments up to 3000ft².

When you want to go to sleep, it can get as low as 28 dB on Sleep Mode, and it will also shut off any semblance of light or sound, helping you to create good hygienic conditions for rest.

There is a 6-gallon tank – that’s 22L if you want to go metric – which means that you can leave the LEVOIT Whole House Humidifier running for as long as 72 hours with no refill needed. A high-speed fan helps with the water evaporation.

Like the Dyson we featured earlier, it will also offer a degree of impurity filtration, with a premium filter. There is a hot or cold mist option. 

Pros

• Low-noise (28 dB)
• Can humidify whole property
• Air filtration
• Smart app ready

Cons

• Replacement filters might be pricey for some

Best for: Quiet humidifier for whole property

#6 – Homvana Ultrasonic Humidifier – 23 dB

Here’s a quiet humidifier for a small room, for a small price. 

At 23 dB, the Homvana Ultrasonic is actually the quietest on our list. Obviously, as it is designed for smaller spaces, it needs less power, and that might account for the super low noise level. Sleep Mode turns all displays off and employs exclusive SilentSpray tech to give you a quietness that you can trust won’t disturb even light-sleeping babies.

Despite the fact it is small, the Homvana H101 has some cool features. There is an aromatherapy option that allows you to add a few drops of essential oil to a purpose-designed pad.

For the price and considering the noise level, this is a solid performer for small bedrooms.

Pros

• Very low noise (23 dB)
• Lights off on sleep mode
• Aromatherapy

Cons

• Not enough power for medium-sized rooms upwards

Best for: Small bedrooms
