What Is an Ultrasonic Humidifier? Why Would I Want One? 

Instead of using a fan to push out water vapors into your indoor environment, an ultrasonic humidifier uses sound waves. These sound waves, which are at ultrasonic frequencies so you are unable to hear them, will vibrate a metal diaphragm contained within the humidifier. These vibrations then turn liquid water into vapor and this is then released into the air thanks to the invisible mists that are created. This is why they are able to operate so quietly.

You’ll find a number of different features and options are available in this category. Some ultrasonic humidifiers offer a top-filling design. Others are small and compact, designed to be a tabletop humidifier for a small room. Some come equipped with a humidistat so you can automatically control interior humidity levels.

The best features in this category, however, are the mineral and mold build-up prevention options that are available from some manufacturers. A good example of this is the Silver Clean technologies that are used by Pure Guardian. This technology prevents mold and mildew growth within the water tank while reducing scale build-up if you’re using tap water that hasn’t been filtered.

What Are the Benefits of an Ultrasonic Humidifier? 

An ultrasonic humidifier offers many of the same benefits as any other humidifier design. You can improve humidity levels, lower the risks of adverse health within your home, and create an atmosphere that helps to protect the structure of your home. Yet an ultrasonic humidifier also brings with it these key additional benefits that are unique to its design.

  • More energy efficiency. Because there isn’t a fan that must be constantly running to push mist into your indoor environment, there is less energy used during every operation period. It is literally pennies per day in utility costs to operate the best ultrasonic humidifiers that are on the market today.
  • Easy to clean. Because sound waves are turning the water into vapor, you don’t have the same levels of mineral content in the air that you breathe. You do get a white dust from the mineral content in your water that must be cleaned and that could be problematic for some, but in general terms, these humidifiers are much easier to clean than their counterparts. Some are even self-cleaning.
  • They are highly affordable. The only other type of humidifier that can compete from a cost standpoint with ultrasonic humidifiers are cool mist humidifiers. It really doesn’t cost much to get a lot of use from this innovative design. 

You’ll begin to experience the benefits an ultrasonic humidifier can provide your home almost as soon as you turn the unit on. If you’re ready to breathe easier every day, then it’s time to find the right humidifier for you today.

How to Find the Right Ultrasonic Humidifier for Me 

When you’re shopping for the best ultrasonic humidifier to meet your needs, there are three important questions that you should ask as you review each product. Let’s take a look at those questions and why they should be asked as you are shopping.

  1. How big of a humidifier do I need? If you only want to provide humidity improvements to a small bedroom, then a portable or compact ultrasonic humidifier is your best option. Tower humidifiers are good for larger bedrooms or other rooms throughout your home. A console ultrasonic humidifier is your best option for whole-home humidification.
  2. How long do I want my humidifier running? Each humidifier in this category has an assigned running time that is based on manufacturer testing. Ultimately this is a reflection of how long you can experience better humidity levels without needing to refill the humidifier.
  3. How much water does the tank hold? Run time is not always associated with tank size. There are some very efficient ultrasonic humidifiers that can operate for 24 hours straight on a small tank, while others can operate just 8 hours on a large tank. 

You’ll also want to decide whether you want a cool mist humidifier, a warm mist humidifier, or one that can provide both mist types for your home. Ultrasonic humidifiers are available in each design, so you’ll have to choose what type you want. Cooler homes may benefit from a warm mist humidifier, yet cool mist humidifiers tend to be safer around children and pets because they don’t contain a heating element within the unit. 

What Are the Prices of the Best Ultrasonic Humidifiers?

Ultrasonic humidifiers are one of the most reasonably priced additions you can purchase for your home. Many entry-level humidifiers in this category can be found for under $30. Mid-sized humidifiers that can handle 400-1,000 square feet of humidification can often be found for less than $75. Even whole-home humidifiers tend to be priced around the $250 mark. It’s easily one of the best investments you can make into yourself and your family this year.

What Do Our Reviews Have to Say? 


This warm and cool mist ultrasonic humidifier gives you the best of both worlds. It works well in even large rooms, has a 2 gallon tank capacity, and 3 settings for customization. All of your controls are directed by the push of a button so you can set your desired levels of humidity within seconds. You can even use it as a vaporizer if you wish. It’s filter-free, very easy to maintain, but we do recommend that you avoid placing this humidifier on carpeting because it doesn’t seem to like any surface that is even remotely uneven.

This large capacity humidifier does a great job of improving humidity levels in most small-to-medium rooms. It offers a number of features, including an aroma diffuser and filtered output, to remove the odors from your rooms that may linger. It’s remarkably quiet, offers nightlight functionality, and automatically shuts off when it runs out of water. We found that the humidifier can run through most of the night, rated at 11 hours, though we got about 9-10 hours on most nights. If you want a humidifier you can fill and forget this might be your best option in this category.

This 5 liter ultrasonic humidifier offers you a 360 degree nozzle so you can be in control of the adjustable mist levels. A traditional knob control allows for customization and the unit will automatically shut off when it runs out of water. It tends to work best in smaller rooms, with the best benefit coming in the bedroom when you need to get some sleep. It does tend to struggle with hard water and scale build-up, so be prepared for frequent cleanings – or use distilled water. Using this model is virtually effortless and it’s quite affordable, which helps it to earn a recommendation from us today.

Why is this one of the best ultrasonic humidifiers? For starters, it offers you 5 key features. It offers an aromatherapy diffuser, air purifier, and ionization in addition to its humidification options, all enhanced by a “mood light,” which functions fairly well as a nightlight. The mist controls are highly adjustable, with user control over nozzle direction and flow rate for the mist. The control knob is pretty standard, as is the removable 1.3 liter tank, but it gets the job done consistently. That’s why we loved taking a look at this model and think you will too.

It’s the timing functions that stood out for us with this particular humidifier. Many of the models in this category don’t include this feature. The controls are rather basic and you have limited customization, but you do have an essential oil diffuser you can use. This ultrasonic humidifier would also make for a good addition to a kid’s room since it has remarkable impact resistance. A drop from waist height did no damage during our review period. It also has 7 LED lighting options for you to enjoy.
