If you want to buy a humidifier, then you have two options: either an ultrasonic humidifier or an evaporative humidifier. This article reveals the benefit of ultrasonic articles to help you decide whether this is the best humidifier for you to buy and use.

What is an ultrasonic humidifier?

An ultrasonic humidifier, however, uses high-frequency sound vibration to produce an extra fine water mist that expelled to add moisture into the room. It’s a very simple device. Manufacturers make the vibrating diaphragm from ceramic or metal, which sits on the water reservoir’s surface to churns the water at a higher frequency to produce droplets 1.

This structure of an ultrasonic humidifier allows the mist to come out from the top when it’s in the shape of a teardrop. It includes a reservoir of water and a diaphragm for vibration.

The vibration of the diaphragm occurs at high frequency to churn the water into tiny droplets. Then the droplets evaporate in the air and add humidity to the room’s air. The sound frequency produced at a top-level to make it inaudible for the human being. That’s why they’re called ultrasonic humidifiers.

The design of an ultrasonic humidifier depends upon the style of the manufacturer. Many of them include fillable tanks while others have the option of inserting a water bottle. Many ultrasonic humidifiers add features like bells and whistles, USB power, LED night lights, LED display pads, and built-in clocks to attract customers.

An ultrasonic humidifier may have cool mist or warm mist function, or both depending on the model.  Models that produce both cold and warm must offer you the best of both worlds, allowing you to adapt the unit to your seasonal needs.

What is the best frequency for an ultrasonic humidifier?

As previously mentioned, ultrasonic humidifier produces high-frequency sound to create vibrations. This frequency varies from models to models. The most frequently used frequency ranges from 0.8 MHz to 1.7MHz by many brands. Even 2.4 MHz frequency used in ultrasonic humidifiers of some brand 2. Ultrasonic humidifiers use vibrating diaphragm transducer to vibrate at a high-frequency oscillation to produce this sound. This frequency silently generates microscopic water droplets that leave the humidifier as a fine mist to humidify the air.

The high frequency creates no danger to the human because it’s inaudible. But the low frequency creates several health problems like headache, dizziness, nausea, etc. All the humidifiers available in the market used the latest technology to produce no effect on the human body. With no kind of hesitation, they all are safe and easy to use. Ultrasonic humidifiers with distilled water prevent the spreading of white dust in your room.

Ultrasonic humidifiers create aerosolized “white dust” by dissolving minerals in the water droplets as a cool fog 3. It’s advisable and recommended using the humidifier with distilled water to prevent the dispersion of contaminants like bacteria, viruses, minerals depending upon the quality of water.

What are the benefits of an ultrasonic humidifier?

Ultrasonic humidifiers have several advantages over evaporative humidifiers. These includes:

They add so much moisture to the air. Besides, with a humidistat, they are best at humidifying the air. Detection of humidity level in the room is necessary prior to use the ultrasonic humidifier. Humidistat plays the role of detection and maintains proper humidity level of the room 4.

The humidifying mechanism of the ultrasonic humidifier is very simple, and this is small and compact to use.

This is quieter than the fan of an evaporative humidifier.

  • It does not generate any heat or use boil water to produce water vapor.
  • Ultrasonic humidifier provide relief from allergies, dry skin, chapped lips, dry throat, sinus congestion, and nose bleeds.
  • The wick or filter in an evaporative humidifier must replace regularly, adding effort and operational cost. But you never have to replace a wick or filter on an ultrasonic humidifier.
  • It costs very little electricity than an evaporative humidifier.
  • It helps in better and sound sleep. It moist the dry air and dry air makes your nose and throat dried and parched during sleep which makes you uncomfortable.

How to maintain an ultrasonic humidifier?

Cleaning is very simple. Detach the nozzle, empty the reservoir and use a brush or scrubber to clean it. Use clean water to rinse all parts and remove any scale, deposits, or film that has formed on the sides of the tank or on interior surfaces. Finally, dry all surfaces by using a clean towel. Disinfectants used to clean your humidifier according to the manufacture guidelines.

How to choose the right ultrasonic humidifier?

If you want to buy and use an ultrasonic humidifier which one you choose will depend on many factors like the size of your room and what types of additional features you want.

Very few portable, single-room humidifiers are common nowadays for their performance over the air pressure, temperature, initial humidity levels, and other factors. The size of the water reservoir also a significant factor while selecting a humidifier. For a gigantic room, it will dry early, so there might need a humidifier with a larger water reservoir. With a compact room, you can use a humidifier with a small reservoir.

Humidistat, a very much essential feature for an ultrasonic humidifier. This will automatically shut off the humidifier if the humidity levels get too high. The ultrasonic humidifier produces excessive humidity into the air. This excessive moisture can lead to dampness or favors the growth of molds. Humidistat plays a preventive role here to avoid these problems. Some ultrasonic humidifiers used aromatherapy oils which adds additional aroma which you can select according to your choice 5.
