Today, we’re going to be looking at how you can find the best “Dual-Mist Ultrasonic Humidifier” for your needs.

Now, let’s get started!

What Is A Dual-Mist Ultrasonic Humidifier?

There are two types of mist that a humidifier can produce. Warm mist, and cool mist. A “dual mist” humidifier produces both types of mist.

Most humidifiers, though, only produce one type of mist. Sometimes it’s warm mist; sometimes it’s cool mist. With a dual mist humidifier, you have access to both types of mist, which gives you a lot more flexibility, overall.

Ultrasonic technology is somewhat unique, in that it uses sound to break apart solid water droplets into vapor. This is done using a small metallic plate that is located within the humidifier. This plate vibrates at what is known as an “ultrasonic frequency”.

Now, the sounds that are produced from this frequency are inaudible to us. But, this particular frequency can do some pretty interesting things. One of these things is, of course, taking the water droplets in the humidifier reservoir and breaking these droplets apart, turning them into a nice vapor/mist.

Then, the humidifier takes this mist and ejects it, adding humidity to whatever room/space the humidifier is located in.

What Are The Benefits Of Owning This Kind Of Humidifier?

Most humidifiers rely on fans to create the mist that they emit. Since ultrasonic humidifiers rely on specific frequencies of sound, they don’t need any fans.

What’s great about this is that, since they don’t have any fans, they make very little noise. The only real noise that these kinds of humidifiers produce is that of the ultrasonic frequency, which is, of course, inaudible.

Compared to most humidifiers, ultrasonic humidifiers are very low-maintenance, as well. You don’t need to change or replace things like pans and steam canisters consistently. Heat isn’t used, either, to produce the mist, so you’ll save some money on electricity costs, as well.

Most ultrasonic humidifiers are portable, due to the lack of fans and other elements. You can easily turn them “On” and “Off” and have them producing vapor very quickly because there is no need for any sort of boiling process.

Why Should I Own A Dual Mist Humidifier?

Humidifiers can help you recover from basic illnesses such as colds more quickly. They can also reduce the allergens and contaminants in your home, which helps get rid of all kinds of nasty allergy-related symptoms.

This is because dry air is more conducive for things like bacteria and viruses. But, when the air is nice and moist, bacteria and viruses are far less effective. This applies to basic illnesses, as well as the risk of infection.

If you have any house plants, the dry air – especially during the winter – usually isn’t too helpful for making sure that those houseplants remain healthy. But, with just a bit of extra moisture, your houseplants will remain healthy.

The same goes for wooden flooring and furniture especially if it is older. Dry air often leads to the degradation of those things, but with a little more moisture, it’s far less likely that things like shrinking and cracking will take place.

What Are The Features That I Should Look For And Consider In A Dual-Mist Ultrasonic Humidifier?

Maximum Room Coverage

If you have a big room, you’re going to need a humidifier that can accommodate that space. Most humidifiers, in today’s market, are designed for bigger rooms. So, it isn’t hard to find a dual mist ultrasonic humidifier that can accommodate your room, whatever its size may be.

However, even if you have a smaller room, purchasing a model that is designed to be used in bigger spaces gives you a great deal of versatility. At some point, you may want to move the humidifier to a bigger space, and if you have a model that supports a larger space, then you have the option to do so.

When you look for a dual mist ultrasonic humidifier, you’ll find that most of them have a maximum room coverage that ranges from five-hundred square-feet to nine-hundred square-feet. However, the ones that are over eight-hundred square-feet tend to be extra expensive. There’s a good chance you don’t really need that much space, so choose one that’s around the seven-hundred to eight-hundred square-feet mark.

Tank Capacity

Ultimately, tank capacity is less important than the other features on this list, but it’s still notable for the sake of convenience.

If your humidifier has a smaller tank capacity, and you intend to run the humidifier for a long period of time, you’ll be refilling the tank quite often.

To prevent that, search for a humidifier that has a tank capacity of at least one-gallon, but one-and-a-half to two-gallons is ideal.

Overall Humidification Performance

You’ll notice that every dual mist ultrasonic humidifier varies when it comes to how many gallons it can vaporize in a single day. You’ll also notice that, for example, a single humidifier may be able to vaporize two-gallons of cool mist in a day, but only one-and-a-half gallons of warm mist.

Performance definitely varies between cool mist and warm mist. Make sure you know which type of mist you’ll be producing most often, and then take into consideration the performance of each humidifier that you look at.

Humidistat And Controls

Some would argue with this, but having a good humidistat and reliable controls are one of the most important elements of a good dual mist ultrasonic humidifier.

Make sure that the humidifier you choose to purchase gives you the exact humidity levels. Make sure it gives you the option to change that level and to customize it, while also allowing you to create a timer and/or schedule for the humidifier.

While these are relatively simple features, they do two very crucial things.
First off, they give you access to this important information. Information that allows you to experiment and see which humidity level is best for you.

Second, having some sort of timer or scheduling feature is essential if you intend to automate the process or want to have it running while you aren’t at home.
