The ultrasonic humidifier works by vibrating a metal diaphragm at ultrasonic frequencies. This creates a high-frequency sound wave that causes the water to break up into very small droplets.

The droplets are then drawn up into the humidifier and released into the air. It’s very effective at dispersing water droplets into the air, which helps to increase the humidity level in a room.

Buying Guide

When you’re ready to buy something, you’ve read all the reviews and need to make a decision. When you are buying an ultrasonic, here are the most important factors to consider


Some key features to look for include mist output controls, nightlight, auto shut off, and mist direction nozzles.

If you are willing to set a higher budget for your humidifier, additional features such as LED Digital Displays, Aromatherapy, Programmable Timers, and Refill Indicators can be convenient to have!

There are different types, and each has a different run time. You should consider how long you’ll need the humidifier to run before purchasing one.

Room Size

The size of the room can be used to determine the moisture output needed from a humidifier. Measure the area that needs some adjustments, whether it’s an entire building, a specific room, or your own office.

  • Up to 25 square feet of space can be covered by travel humidifiers.
  • Between 25 and 299 square feet can be covered by small room humidifiers.
  • Humidifiers for medium rooms cover 300 to 499 square feet.
  • A large room humidifier covers an area of 500 to 999 square feet.
  • Console humidifiers for the whole house cover up to 1,000 square feet.

Ease of Use

The key is to know what’s available before you make your purchase, so you’re sure to end up with a machine that meets your specific needs.

This is an important consideration because you don’t want to have to spend time trying to figure out how to use the humidifier. Look for models that have easy-to-understand instructions or features that make it easy to control the humidity level in your room.


It’s come in a variety of prices, depending on the brand, features, and design. Some can be quite expensive, so it’s important to consider how often you’ll be using them and what features are a must-have for you.

It’s important to consider how much you’re willing to spend. Models that are more expensive typically have more features, but they may also require more maintenance. It’s worth it to choose a model that you’ll be able to use regularly and won’t require a lot of upkeep.

Humidity Levels

The perfect humidity range for optimal air health is anywhere between 25% and 55%. Having a humidity/temperature gauge (hygrometer) in your room makes it easy to monitor the relative humidity level.

You don’t want to have too little humidity, as levels below 25% can be unhealthy.

However, you also don’t want too much moisture in the air, as levels above 55% can encourage the growth of mold, bacteria, fungi, and dust mites.


Are Ultrasonic Humidifiers Safe?

Ultrasonic does not produce any heat, which makes them safer than steam humidifiers that boil water to create vapor.

What is the healthiest type of humidifier?

According to the U.S. National Library of Medicine, cool mist humidifiers are generally the safest option for people and pets. Warm mist, on the other hand, can be dangerous if you’re close enough to them and they start to heat up

Wrap up

All these 11 humidifiers will surely give you a great humidity experience. But if I had to pick my best 3, they would be levoit lv600, Frida Baby, and Everlasting Comfort.

I like the levoit because of the hybrid design and digital control panel.

if you have any other questions , don’t hesitate to ask!
