If you need a humidifier for baby nursery or bedroom, you’ll need the quietest humidifier you can get.
A humidifier is a handy appliance that does more than making the air around you pleasant. Dry air in your home can make the occupants experience irritation or dryness in the nose, skin, throat, lips as well as other health-related issues.
Fortunately, a humidifier can help decrease the chances of such conditions happening under your roof.
Unfortunately, a noisy humidifier can do the opposite- disturb house inhabitants and even at times keep you from enjoying a good night’s sleep.
For this reason, you will need a quiet humidifier- and we are here to help. We’ve compiled this guide to help pinpoint the important features to consider before investing in a humidifier.
What Is a Humidifier?
A humidifier is a type of therapy device that adds moisture to your home indoor environment to help prevent dryness associated with irritations of different parts of the body.
A humidifier is highly effective in treating dry skin, throat, nose, and lips. According to research, a humidifier can also help ease the common cold and flu symptoms.
On the other hand, overusing humidifiers has been shown to worsen respiratory problems. Therefore, it’s important to learn how to use one properly.
Types of Humidifiers?
There are different types of humidifiers available on the market today. For the purpose of this guide, I shall only be discussing the most popular ones and give you the verdict on what I think the best ones are. Let’s get started.
Cool mist Humidifiers
Cool mist humidifiers have a filter that traps minerals and other impurities as they emit an invisible cool mist that evaporates into the air.
These are easy to clean and much effective in large rooms and warmer climates. Most people find cool mist easy to breathe than warm mist.
Unfortunately, cool mist humidifiers are noisier than warm mist humidifiers. However, some people find this humming noise soothing and a perfect substitute for a white noise machine.
They also require more maintenance since the filter often needs to be replaced to prevent mold and algae growth.
If you have small kids and pets in your house, you’re better off with a cool-mist humidifier. Accidents often occur, and with a warm mist, you risk burns.
Warm Mist Humidifiers
Warm mist humidifiers produce a warm and soothing mist that you can see and feel. They are great for use in cold climates and work great in treating flu and cold.
Unlike their cold mist counterparts, warm mist humidifiers are quieter and produce a cleaner mist.
Unfortunately, warm mist requires regular cleaning and is more difficult to clean. And they cover a smaller area compared to cold mist humidifiers.
These devices heat the water to produce a vapor that is then cooled before being released. The best part is that the heating process helps eliminate or decrease the risk of bacterial contamination and enhances purity.
Like the cool mist above, the warm mist is compatible with medicated products and inhalants.
If you require a humidifier for a baby nursery, I highly advise you against a warm mist humidifier. This is because the heater water is a safety concern for your baby.
Whole House Humidifiers
As the name suggests, these will cover a large area. You shouldn’t confuse these units with the ones you attach to the HVAC system or the furnace.
Whole-house humidifiers cover an extensive area without attaching to the HVAC or furnace. They are larger and are not “portable.” The best part is that you can go for several days without the need to refill water.
However, it’s important to note that you’ll be required to clean the tank at least once a week with a whole-house humidifier. You should also replace wicks and filters at least once every three months.
It’s highly recommended you use filtered, distilled, or bottled water to avoid the white dust that most humidifiers produce.
Ultrasonic humidifiers have a metal diaphragm that vibrates at an ultrasonic frequency just like a speaker.
This vibration produces water droplets further circulated in the air by a fan. Ultrasonic humidifiers are the quietest and produce a cool fog, although some produce a warm mist fog.
These units can produce a white dust, and therefore, I’d highly recommend you use distilled or bottled water.
Ultrasonic humidifiers require less maintenance and are easy to operate and maintain.
If you’re looking for a humidifier for bedroom, baby nursery, or use in rooms that require silence, I would highly recommend Ultrasonic Humidifiers.
The best part is that some ultrasonic humidifiers have pre-programmed settings that allow you to control humidity depending on the outside climate.
Unfortunately, these units are more expensive than other models in this guide. But I’m better off spending more cash for quietness and energy efficiency.
A-List of Quietest Humidifiers on the Market
Below are the seven most silent humidifiers on the market. These units are handpicked not only based on their sound decibel rating but also by considering other important factors- i.e., large water tank, ease of cleaning, and much more.
For ease of selection, I have divided these units under different categories with the best picks in each category.
Quiet Humidifier for Bedroom
An ideal humidifier for a bedroom should be quiet and compact enough not to take up the entire space in your bedroom. The humidifier should also be safe to use, especially if you have kids in the room. In this case, a warm mist humidifier wouldn’t be ideal.

Sleep Mode and nightlight can be a perfect solution when installing it in your child’s nursery or when you want to sleep like one.
Unfortunately, like most humidifiers, this unit lacks a handle to carry it from one room to another, which can result in spills since the tank is not attached to the base.

Quietest Humidifier Buying Guide; What to Consider
Before you buy your new humidifier, it’s essential to pay attention to some very important details.
These details may appear less important at first but will play a very important role later. Let’s have a look at the features to consider:
Investing in a quietest bedroom humidifier like the Homasy can make a huge difference, especially when you’re planning to keep it running at night.
You don’t want to have a humidifier that whistles all night long because you won’t get to sleep.
Our humidifiers reviewed above all have sound decibel ratings between 28-38 dB. This is an excellent range of nose especially when choosing a quiet humidifier for your bedroom or nursery.
Water Tank Capacity
A water tank is an important feature when choosing a humidifier. You don’t want to wake up in the dead of night to – add more water to the tank.
Instead, choose a tank that will have your humidifier running for at least 16 hours or 24 hours.
A humidifier with the largest water tank capacity in our guide is AIRCARE MA0800, with a 2.5 and 3.6-gallon water tank and can run for over 48 hours between refills.
Cool mist humidifiers produce cold mist creating a cool, humid home environment. On the other hand, warm mist humidifiers boil the water inside and release warm mist to the environment.
While warm mist help fights bacteria growth, they are not recommended for use in nurseries or generally in homes with kids.
The quietest cool mist humidifiers in this guide are Homasy and VicTsing Humidifier. Fortunately, other models allow for adjustments between cool and warm mist like the Cool Mist Humidifier (BUL9500-SHP) and Bionaire Ultrasonic Warm.
If the room you want to humidify is enormous, it’s essential to know the humidifier coverage before purchase.
You don’t want to buy a humidifier only to realize that it’ll humidify a quarter of your room.
You don’t want to buy a humidifier designed for whole-house coverage when all you want is to use it for one room- that would be a waste of money, space, and energy bills.
There are additional features that you should consider before buying a quiet humidifier. For example, automatically shut-off feature comes in handy when you leave your unit running.
Nightlight is great when buying a humidifier for the baby room or when you want to sleep like one. LED indicators are also great.
Humidifier Making Buzzing Noise
If you have an existing cool mist humidifier that’s noisy, there are ways to make it quiet. While the noise is less than the amount produced by other home appliances such as refrigerators, you may find it hard to sleep. Fortunately reducing noise levels is very simple:
Adjust the fan and impeller
Remove the motor from the water and take off the top of the impeller tip. It’ll allow more airflow through the system and help in noise reduction.
You can also replace the filter and remove the fan, and this will help reduce noise.
Move the fan
The amount of noise generated by the humidifier fan can increase depending on where the unit is placed in the room.
Make sure that its place on a completely flat surface, and the cool mist humidifier is away from the walls and other objects that could affect airflow.
It’s also recommended to place the humidifier in a folded napkin or towel, and this will help reduce vibration transmission through the floors.

A humidifier is something easy to maintain and shouldn’t take most of your time while you do this. Failure to clean your humidifier can facilitate the growth of mold, bacteria, and other invasive micro-organisms.
Below are some essential tips on how you should maintain a humidifier.

- It’s essential to wash and effectively clean the humidifier after each use.
- Use the recommended tools and chemicals to clean the unit
