How does an ultrasonic humidifier work?

Recently at a friend's house I saw this little weird looking white and blue box next to the couch where I was sitting; when I asked my friend what it was, she casually said, "Oh that's just our humidifier" and changed the subject. I'm a curious gal, I instantly googled the word "humidifier", even if I already had a slight clue of what it was, after several clicks I had a clear idea of what they are but then I was curious on how does an ultrasonic humidifier work? Here's what I found.

First let me tell you about my initial findings of this impromptu research. A humidifier is an appliance that gradually increases humidity (hence its name) in a room or an entire household. When the air is dry due to different weather circumstances, hot or cold, the humidity in the air drops to 10 or 20% and this can cause respiratory conditions. Even furniture can be affected by this low moisture environment. In low humid places static electricity is easily charged and causes constant fabric clinging and sticky dust everywhere. This is why there is a need to have a humidifier in the room, especially if you plan to be in that room for a long period of time. There are different types of humidifiers: natural humidifier, vaporizers, impeller humidifier, force-air humidifier and the ultrasonic humidifier.

So, how does an ultrasonic humidifier work? It's simpler than it sounds. An ultrasonic humidifier has a metal diaphragm that is usually located on the bottom of the appliance and it vibrates with an ultrasonic frequency. This creates a silent foggy mist of water, great to use while sleeping. A fan in the humidifier pushes the tiny water drops up and out of the machine; the droplets quickly evaporate into the air flow. It is extremely important to constantly clean the humidifier as prone-to-moisture pathogens could grow in the small tank causing bacterial contamination to spread in the air. This microbe contamination could be prevented by using distilled water even though there is no absolute security of entirely pure water.

This humidifier is safer because it doesn't use boiled water, yet the down point is exactly that. Since the water is not boiled before leaving the equipment, it could carry bacteria. Therefore the relevance in keeping it clean and disinfected before it is used.

So, as long as you keep it neat and hygienic, you are good to go with keeping the room humidity at a proper level, even more now that you are aware on how an ultrasonic humidifier works.

Now, there are all kinds of shapes and sizes. There's even humidifiers for the kid's room in shapes of ducks, cows or dogs... really cute! At this point it is really your personal choice and your home decor.
