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 theair.

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

Its the latter that vibrates at an exceptionally highfrequency (it so high such that no human being can hear). 

These vibrations cause microscopic water droplets to formand be blown to the air filling your environment with a nice, rehydratinghumidity.

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 its imperative that you have a humidifier around.

Types of ultrasonic humidifiers

Majorly, youll find thefollowing types of ultrasonic humidifiersout there:

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

Lets briefly look at each of the above types:

Portable/personal ultrasonic humidifiers

These happen to the smallest and most lightweight.

Theyre pretty portable and thus convenient for yourtravels, car, or office usage.

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

Console ultrasonic humidifier

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

They typically come with wheels to allow you to push it tothe position where its most effective in distributing moisture.

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

They are, however, costlier than portable models.

Ultrasonic humidifiers for furnace

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

The vapor is then propelled into your furnaces plenum by afan.

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

Room to Moisturize

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

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

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

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

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

Ease of cleaning

There will always be a likelihood of residue mineralssticking to some parts of your humidifier because of how these models generatethe water particles.

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

Additionally, be sure to check out the manufacturersguidelines concerning cleaning; the last thing you want is to damage yourappliance by using harmful materials/solvents to clean it.

Size is important too

If youre a fervent traveler, research how easily it can bepacked/carried around.

Here Im assuming that youre choosing a portable modelbecause the console ones can be too bulky.

Other questions to ask

  • How longdoes one fill last? The longer, the less the disruptions at night.
  • Does it diffuseessential oils? You might want to purchase a humidifier with an essentialoils container to enjoy the multiple benefits of engaging in aromatherapy suchas stress relief.
  • Is the mistoutput 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 bekeen 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. Someof them come with even seven different pleasing colors that you can customizeto taste.
  • Programmabletimer-An ultrasonic humidifier with a programmable timer makes it easierfor you to control how it works and the duration of the humidificationoperation.

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

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

  • Waterlessauto-shutdown-You risk damaging your humidifier if you, by chance, leaveit to continue running when the reservoir is empty.

And because monitoring the waterlevel continuously is often quite stressful, an ultrasonic humidifier with a waterlessauto-shutdown is recommended.
