What is an Ultrasonic Humidifier?
There are three main types of humidifiers – warm mist, ultrasonic, and evaporative – and ultrasonic is one that’s rising in popularity. It’s considered a cool mist humidifier because the water isn’t heated in any way.
The way it works is a bit more complicated than the other types out there. Inside the humidifier where the inner workings create the mist, there’s usually a small metal plate.
High-frequency sounds create a vibration against that plate, which affects the water inside the tank. The molecules literally split apart into the mist that’s then emitted from the machine.
Why You Might Prefer The Best Ultrasonic Humidifier
An ultrasonic humidifier uses no heat to create humidity, so it’s a safer choice than a warm mist humidifier. These are the types of humidifiers that would work well in a baby’s nursery, a child’s room, or around pets. There’s no risk of an accidental spill leading to burns.
The ultrasonic versions are a bit pricier than evaporative humidifiers, but not by much. Plus, there’s no need to buy filters in most cases. You simply pour water in and a cool mist comes out.
Unlike other humidifiers, these are quieter because there’s no fan or boiling of water. It makes for an ideal humidifier in the bedroom.
Of course, all humidifiers have their benefits and drawbacks. Keep reading to find out more about all the pros and cons of an ultrasonic humidifier.
Benefits & Drawbacks of an Ultrasonic Humidifier
The benefits generally outweigh the drawbacks of an ultrasonic humidifier. You’ll have to decide for yourself, of course.
Benefits of an Ultrasonic Humidifier
Lower noise than a normal humidifier
Seeing as how there’s no fan operating, ultrasonic humidifiers are one of the quietest units you can buy for your home.
That means you can keep one in your living room and watch movies without wondering where some random noise is coming from. Or you can keep one in your bedroom without being awoken by your best humidifiers.
Maintenance costs less
Usually, there are no filters to change, and no bulbs to swap out in an ultrasonic humidifier. You just add water to the tank and turn it on. Cleaning is a necessary part of having a humidifier, and you should probably do it at least once per week, but that’s true of any type.
Energy-efficient compared to others
All humidifiers need an electrical outlet to operate. The difference with the ultrasonic types is that they don’t require nearly as much energy to run. So, you shouldn’t see much of an increase in your energy bill at all.
Size is smaller and compact
Generally, ultrasonic humidifiers are smaller in size than its competitors. That makes it easy to place these humidifiers almost anywhere in your house, such as a nightstand by your bed.
Year-round durability – Long-lasting
Although many people put their humidifiers away when winter has gone, an ultrasonic humidifier can be used year-round to help combat dry air.
It isn’t just forced-air heaters that can dry out the air in your home – air conditioners do the same. And a cool mist humidifier won’t raise the temperature in your house, even during the summer.
Ultrasonic humidifiers don’t use heat of any kind to create humidity, so they’re safe to use around children. Even if a spill occurs, the water isn’t hot, nor are any of the components. It’s one of the safest humidifiers you can use.
The output may be less powerful
Some humidifiers seem like a good buy based on reviews and price, but you may discover that they don’t affect the humidity in your home as much as you’d like.
It’s important to look at the output of humidity and make sure the ultrasonic humidifier you choose will raise the humidity as much as you want.
White dust production or emission
The most well-known drawback of the ultrasonic humidifier is that it produces white dust, which is emitted along with the mist.
This dust is just the minerals in the water, and most ultrasonic humidifiers don’t filter that out. You can use demineralization additives or distilled water to avoid it, but that gets pricey.
Bacterial and mold growth
All cool mist humidifiers have a bacteria issues. Water sitting in a tank is bound to grow bacteria, and there’s always a potential for mold growth. Warm mist types don’t have much of an issue because the heat kills most of the germs.
That means you’re going to have to clean your humidifier well using white vinegar or a store-bought disinfectant or cleaning solution.
General purchase cost is higher
When compared to other cool mist humidifiers, the ultrasonic is slightly more expensive. You won’t spend that much more, but when you’re on a budget, this could affect your decision.
