Best Ultrasonic Humidifiers for 2022

An ultrasonic humidifier carries a number of benefits over other types of humidifiers.

For example, they happen to be the quietest and hence the best types of humidifiers for spaces where silence is precious such as your bedroom, baby nursery, offices, condos, libraries etc.

Another thing: these units mostly produce cool, surrounding mist and you’ll lounge in refreshing moisture all year round.

In comparison, humidifiers that emit warm mist (heated moisture) only can raise the room temperature making your rooms less habitable especially if you live in a zone with a warmer climate.

This guide will help you select the best ultrasonic humidifier for your needs.

You shall also discover our favorite ultrasonic humidifiers from what the market offers at the moment.

Read to the end.

What is ultrasonic humidifier?

An ultrasonic humidifier is a class of humidifiers that use ultrasonic technology (high-frequency sound vibrations) to generate moisture and spread it to the air.

The units have a built-in reservoir and a vibrating component such as a diaphragm.

It’s the latter that vibrates at an exceptionally high frequency (it so high such that no human being can hear). 

These vibrations cause microscopic water droplets to form and be blown to the air filling your environment with a nice, rehydrating humidity.

You certainly understand that unrestrained air dryness during winter can lead to horrendous effects such as dried up lungs, skin, sinuses and the like and it’s imperative that you have a humidifier around.

Types of ultrasonic humidifiers

Majorly, you’ll find the following types of ultrasonic humidifiers out there:

  • Portable/personal ultrasonic humidifiers
  • Console ultrasonic humidifiers
  • Ultrasonic humidifiers for furnace

Let’s briefly look at each of the above types:

Portable/personal ultrasonic humidifiers

These happen to the smallest and most lightweight.

They’re pretty portable and thus convenient for your travels, car, or office usage.

A portable ultrasonic humidifier is a clever way to checkmate the crippling consequences of being surrounded by unsavory dry air such as nosebleeds and cracked lips before they get the better of you.

Console ultrasonic humidifier

Ultrasonic console humidifiers tend to be larger than portable models and often add moisture to the whole home (as opposed to a personal space like in portable humidifiers).

They typically come with wheels to allow you to push it to the position where it’s most effective in distributing moisture.

You will find them quite effective. In fact, many of them moisten your space within a couple of minutes.

They are, however, costlier than portable models.

Ultrasonic humidifiers for furnace

These are essentially ultrasonic transducers that vibrate water making it a fine mist.

The vapor is then propelled into your furnace’s plenum by a fan.

These types of ultrasonic humidifiers ensure there’s adequate moisture in centrally heated homes and are mainly fixed to the furnace.

Ultrasonic Humidifiers Buying Guide

Ultrasonic humidifiers are widely available in malls, local convenience stores, online, and more.

Before you order one, however, there are several things you should beware of.

Keep reading.

Room to Moisturize

Size is a big thing and you have to put it into consideration…

How big is the room you want to use the humidifier in?

Is it a tiny bedroom? Or a medium-sized baby nursery? Or perhaps, a vast office space?

If you need a humidifier for the entire home, you should pick a console ultrasonic humidifier.

For smaller rooms and tight spaces, say office cubicles, you should be fine with a portable ultrasonic humidifier.

Ease of cleaning

There will always be a likelihood of residue minerals sticking to some parts of your humidifier because of how these models generate the water particles.

As a result, for any humidifier you intend to buy, ensure that cleaning it is as easy as possible.

Additionally, be sure to check out the manufacturer’s guidelines concerning cleaning; the last thing you want is to damage your appliance by using harmful materials/solvents to clean it.

Size is important too

If you’re a fervent traveler, research how easily it can be packed/carried around.

Here I’m assuming that you’re choosing a portable model because the console ones can be too bulky.

Other questions to ask

  • How long does one fill last? The longer, the less the disruptions at night.
  • Does it diffuse essential oils? You might want to purchase a humidifier with an essential oils container to enjoy the multiple benefits of engaging in aromatherapy such as stress relief.
  • Is the mist output satisfactory? You want to go for a unit with decent dispersal of mist.
  • Design: Is it aesthetically pleasing?

Other features

When shopping for an ultrasonic humidifier, you should be keen on features that make it convenient to use.

We list some of them below:

  • LED lights– Ultrasonic humidifiers with nightlights help bring glamour to your rooms. Some of them come with even seven different pleasing colors that you can customize to taste.
  • Programmable timer-An ultrasonic humidifier with a programmable timer makes it easier for you to control how it works and the duration of the humidification operation.

If, for example, it takes 30 minutes to restore cozy humidity levels, you set it to run for 30 minutes.

This can help lengthen the lifespan of your appliance as it ensures that it only runs when needed.

  • Waterless auto-shutdown-You risk damaging your humidifier if you, by chance, leave it to continue running when the reservoir is empty.

And because monitoring the water level continuously is often quite stressful, an ultrasonic humidifier with a waterless auto-shutdown is recommended.

The first highlight here is its hybrid mist feature- this unit can disperse either warm or cool mist depending on your needs.

Secondly, the mist is quite strong- in fact, it’s at 300ml/hour actually better than in the famous Everlasting ultrasonic humidifier.

Neither is the tank too bad- the 1. 5 gals capacity will have it run about 20-36 hours without interruption.

Not to be outdone by other ultrasonic humidifiers, Levoit has as well added a handy essential oil features to facilitate your aromatherapy sessions.

And it’s great that you can switch the mist direction when you wish to thanks to the 360-degree mist nozzle.

The integrated nightlight is wonderful too and will provide a soothing ambiance to make your baby sleep soundly.

We doubt that there’s a better-placed unit to serve in medium-sized offices, bedrooms, and such rooms (up to 250 sq. ft.) as well as this model.

Its 5-year warranty is among the leading in the industry.
