What is An Ultrasonic Engine? How the Ultrasonic Cool Mist Humidifier from Everlasting Comfort Works

The world we live in today is full of amazing technology, extremely fast broadband and 5G, and instant accessibility to almost anything and everything we want.

In fact, the technology that our everyday appliances are made with is so advanced that it can feel like we are living in a futuristic world. One of the game changers recently has been the ultrasonic cool mist humidifier.

This humidifier is not like the others. It uses a metal or ceramic diaphragm that gets mist out into the air we are breathing. The way the diaphragm works is through vibration, which essentially creates lots of little water droplets as a result. The mist that is created can be different temperatures, while the colder mist is often the safer option if you have kids around.

So how does this diaphragm work? It’s all thanks to the humidifier’s ultrasonic engine. We’re going to dive into everything there is to know about this must-have humidifier for your bedroom.

What’s Different About the Ultrasonic from the Evaporation Humidifier?

Many people are probably familiar with the evaporation humidifier option. But the design and functionality of this is very different from the ultrasonic humidifier. This is because the evaporation humidifier is designed to absorb droplets of water, whereas the ultrasonic humidifier is designed to create them.

With such a different process of ultimately getting fresh mist into your home, it is no surprise that the mechanics behind both designs are so different.

How an Ultrasonic Humidifier Works

You do not have to be a technical genius to understand how an ultrasonic humidifier works. All you really have to understand is how an ultrasonic engine operates, which we are about to explain to you in the most simplistic of ways.

1. The Principles Behind Ultrasonic

Any device that uses an ultrasonic engine will ultimately be able to transform electricity into airwaves. This is accomplished by emitting short and frequent pulses that are done through sound. This is essentially what the ultrasonic engine does—sends out a sound that in turn creates airwaves that bounce back.

2. Ultrasonic Humidification Explained

So how does an ultrasonic engine actually create humidity? Simple, really! Humidifiers are designed to work when they are immersed in some sort of water. This submersion essentially helps convert electronic signals into a movement that produces mist.

Ultrasonic humidifiers use something called the cavitation bubble implosion. This is when the speed of the engine increases to a point where the water droplets are dispelled into the air. There is basically a tiny vacuum that compresses all the water drops and forms air bubbles, which is this known as the cavitation bubble implosion.

The other factor to remember is the capillary wave theory in relation to the ultrasonic engine. Cavitation happens when capillary waves are created. This is the result of water drops breaking and then dissipating in the air—essentially becoming vapor that is absorbed and blown out into the air.

So in a nutshell, the ultrasonic humidification process works by combining both the cavitation bubble implosion and the capillary wave theory.

3. The Simple Step-By-Step Process

The entire process of how an ultrasonic humidifier works can be defined in five simple steps. First, the engine creates a very high frequency that sends vibrations into the water. This then causes the water to become out of sync with the vibrations, causing it to break down into water drops. These water drops are then turned into vapor, which gets released into the room. When the water drops are released, it sends a cool mist into the surrounding environment.

Why Ultrasonic Humidifiers are the Best

So what makes ultrasonic humidifiers so much better than the other alternatives? There are several qualities to consider.

1. They are Safer

Plain and simple, ultrasonic humidifiers are safer. This is because there is no steam involved, which poses high levels of risk of someone getting hurt if the humidifier is knocked over. Ultrasonic humidifiers use no steam, so simply less risk is involved.

2. They are Quieter

Another benefit of ultrasonic humidifiers is that they are also extra quiet. Other types of humidifiers are known to be quite noisy. But the contrary is true when it comes to ultrasonic, which creates vibration sounds in near silence.

3. They are Easy to Clean

Taking good care of your humidifier is really important. You want it to be easy to clean and have a low risk of mold forming. Cleaning ultrasonic humidifiers are simple, straightforward, and requires a lot less effort than others.

4. They Save Energy

Some humidifiers require a lot of energy to operate. But ultrasonic humidifiers require very little. In fact, it takes less energy to run one of these things than boiling a pot of water. So it is environmentally friendly too.


Ultrasonic humidifiers are changing the game when it comes to getting fresh air into your home. So why not get one into yours today?
