Top 15 Quietest Humidifier for Bedroom and Baby Nursery

What Is a Humidifier?

A humidifier is a household appliance or device that is used to increase the moisture or humidity level in the air of a room or enclosed space. The primary purpose of a humidifier is to add moisture to the dry air, which can have several benefits for health, comfort, and the environment.

Humidifiers work by dispersing water vapor into the air, effectively raising the humidity level.

They 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 are a popular type of humidifier that provide moisture to the air in the form of a cool, room-temperature mist. These devices use various methods to disperse moisture into the air without heating the water, making them a safe and energy-efficient option for increasing humidity levels in a room.

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 are a type of humidifier that use a heating element to heat water, producing warm steam or mist that is released into the air.

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

Whole house humidifiers are HVAC (Heating, Ventilation, and Air Conditioning) system accessories or standalone units designed to increase the humidity levels throughout an entire home. Unlike portable humidifiers that are limited to a single room, whole house humidifiers are integrated into the home’s heating and cooling system to deliver moisture to all living spaces.

Here are some key features and advantages of whole house humidifiers:

  • Comprehensive Coverage: Whole house humidifiers distribute moisture evenly throughout your entire home, ensuring that all rooms benefit from improved humidity levels. This makes them ideal for maintaining consistent comfort levels in large houses.
  • Seamless Integration: These humidifiers can be integrated with your existing HVAC system, so you don’t need to worry about taking up floor space or dealing with the noise associated with standalone units. They operate quietly and efficiently alongside your heating and cooling systems.

Ultrasonic Humidifiers

Ultrasonic humidifiers are a popular type of humidifier that use ultrasonic vibrations to produce a fine, cool mist or warm mist (depending on the model) that is released into the air to increase humidity levels. These humidifiers are known for their quiet operation and effectiveness in adding moisture to the indoor environment.

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.

  • Quiet Operation: Ultrasonic humidifiers are often praised for their whisper-quiet operation. They use high-frequency vibrations to create the mist, making them suitable for bedrooms, nurseries, offices, and other quiet spaces.
  • 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.

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.

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:

Noise Level

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.

Mist type

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.

Coverage area

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.

Extra Features

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.


What Is the Quietest Humidifier on The Market?

The AquaOasis™ Cool Mist is the quietest humidifier on the market. While there are other humidifiers with similar decibel ratings, the AquaOasis™ Cool Mist wins thanks to its bonus features, including the 2.2litre/ 0.5-gallon tank capacity as well as the 360° adjustable nozzle. It’s also a filter-free humidifier which is excellent since you won’t have the hassles of changing the filter every now and then.

Another option that’s also quiet is the Mooka Humidifier Diffuser. All these units are safe to use in a baby’s room or if you have pets in your house.

Who Makes the Quietest Evaporative Humidifier?

I wouldn’t be wrong to say that AIRCARE is the best brand that manufacturers the quietest evaporative humidifiers.

AIRCARE is a brand that’s been around for more than 7 decades, and it’s headquartered in Little Rock, Arkansas.

What I love about the AIRCARE is its uniqueness in designing state-of-the-art humidifiers, with some having some nice wooden finish that anyone would confuse for a piece of furniture.

If you want an evaporative humidifier that’s uniquely designed, then consider one from the AIRCARE brand.

What Is the Quietest Economy Humidifier?

If you’re on a budget and want something that will be as quiet as top budget humidifiers, then consider choosing HemingWeigh 28 Decibels Ultrasonic.

This unit boasts excellent features you will find in most quiet humidifiers, and the best part is that it operates at 28 decibels as quiet as a whisper. The only problem is that the humidifier is only effective for small rooms measuring up to 280 square feet.

How Should I Maintain a Humidifier?

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.

  • Read the instruction manual and follow each to the latter
  • It’s essential to wash and effectively clean the humidifier after each use.
  • Use the recommended tools and chemicals to clean the unit
  • Use demineralized water/ distilled water every time
  • Filter replacement is a must to keep the unit properly functioning
  • The area around your humidifier should always be dry
  • Unplug the unit after each use

Can I add Fragrance or Essential Oil?

Some brands allow this option but others don’t. I would always recommend you get in touch with the manufacturer or contact an expert to help you. In some cases, adding anything other than demineralized water to the humidifier could destroy the circuitry.

Final Thoughts

Whether you’ve skipped to our final verdict or still trying to figure out the best silent humidifier, here’s our final verdict.

The TaoTronics is the quietest humidifier for bedroom and Homasy are our pick for best quiet humidifiers for the money.

The VicTsing Cool Mist Humidifier is excellent if you are looking for a good humidifier but have budget restrictions. At 32 decibels it can humidify rooms up to 270 square feet. That’s perfect  for small and medium-sized living rooms, bedrooms and nurseries.
