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.
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 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.
The benefits generally outweigh the drawbacks of an ultrasonic humidifier. You'll have to decide for yourself, of course.
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 humidifier.
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.
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.
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.
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.
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.
The most well-known drawback of the ultrasonic humidifier is that it produces a 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.
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 off. That means you're going to have to clean your humidifier well using white vinegar or a store-bought disinfectant or cleaning solution.
When you have a large space that needs more humidity, you need a humidifier that can handle the job, and the Everlasting Comfort Ultrasonic Humidifier could be the right one. It can add moisture to the air of a space up to 400 square feet in size. The tank holds about 1.6 gallons of water, making it a bit larger than most of its competitors. Another benefit of this humidifier is that it also works as a diffuser, so you can add essential oils to add a calming scent to the room. The runtime on this humidifier is up to 50 hours, so you won't have to refill it every single day, if you keep it on low.
Like other ultrasonic humidifiers, this one is fairly quiet, so you can keep it in any room without being disturbed. Of course, you'll have to clean this unit often to ensure bacteria doesn't build up, and you might have some difficulty getting to every nook and cranny. The LED nightlight is nice extra, so you can keep it on for little ones who are afraid of the dark, or use it yourself to help you find your way to the bathroom at night. Some people reported leaks with this unit, but it didn't seem to be a common issue.
If you need a larger ultrasonic humidifier to add moisture to a big room, this one might work well for you.
Unlike most ultrasonic humidifiers, the LEVOIT cool mist ultrasonic humidifier with a 4-liter tank includes filters to help combat that pesky white dust that usually comes with these types of units. There's a ceramic filter that removes impurities in your water, so there's less, if any, dust emitted onto your floor and furniture. There's also a carbon filter, which can be replaced. So, even if tap water goes in, the mist that comes out is clean and purified. You should be able to get about 30 hours of runtime out of one tank of water, as long as you run this unit on low.
You only get two vapor settings with this ultrasonic humidifier: low and high. If noise is a concern, choose the lowest setting. Even on the high setting, though, the sound that comes from this unit is like white noise, so it should be soothing. If essential oils are your thing, you'll likely appreciate the oil try included on this ultrasonic humidifier. Another bonus is the nightlight, which you can turn on or off, as you see fit. The biggest issue with this humidifier is that it may need to be propped up so water flows properly. And leaks were reported, but it didn't seem to be that big of a deal.
If you're looking for a moderately-sized ultrasonic humidifier to add some moisture back to your home's air, then this might be a good unit for you.
Although the PurSteam Ultrasonic Cool Mist Humidifier is not nearly as large as some of its competition, it's one of the highest-rated and popular units available. The longest runtime for this humidifier is 17 hours, which seems short comparatively, but it's still enough to last through the night and then some, if on a low setting. The quiet operation makes this a good choice for a bedroom, and the little noise it does make is considered soothing by most.
You won't be able to use this one as a diffuser, at least not officially. There's no essential oil tray, but many people have added oils to the tank without issue. And like all humidifiers, this one needs to be cleaned regularly. It's easier to clean than others because you can disassemble it and clean every part. It includes a nightlight, which is helpful in a bedroom, but you can also shut that part off if it bothers you. Defects happen, and this ultrasonic humidifier is no stranger to that, but customer service seems to be on the ball.
If you need an ultrasonic humidifier that doesn't take up too much room, but can still provide humidity for a long time, this one might be worth considering.
While all ultrasonic cool mist humidifiers work essentially the same way, the TaoTronics Cool Mist Humidifier gets higher marks for having features others in the same price range don't. The tank is a decent size at 4 liters, so you should only have to fill it once per day. At the lowest setting, you should expect about 15 hours of humidity out of this unit, but some have reported up to 24 hours of moisture. Like many other units, this one has auto shut off and a nightlight. You can also set a timer to let it run for a specified amount of time.
One of the best features of this unit is the LED display that shows you the level of mist, the timer, and even the level of humidity in the room. The included humidistat alone might be worth getting this unit. It also has a nighttime mode, which shuts off all the lights, except one, and operates at a quieter level. A filter helps reduce the white dust that's produced, but some still gets through. And this unit isn't that easy to clean. Some areas are hard to reach, so mold can still grow. Some people suggest cleaning this humidifier every two days to keep mold at bay.
If an ultrasonic humidifier with a humidistat is what you need, this might be your best option.
As people buy more and more ultrasonic humidifiers, feedback is shared, and manufacturers improve upon the design of these units. The PROALLER cool mist humidifier shows some of those improvements off. The control panel for this unit has a touchscreen instead of buttons, and the LED screen shuts off when you choose the nighttime mode. There's an included thermostat and humidistat, so you know what the levels are at all times. However, the thermostat only shows the temperature in Celsius, which is an odd choice given this is sold in the United States, as well.
The 6-liter tank capacity is generous, and if you choose the lowest setting, you can get 48 hours of mist out of this machine. At the highest setting, you can still expect up to 18 hours of humidity. There are also two filters that work to keep your water and air clean. You'll have to clean them regularly to keep mold and bacteria away, and this could mean cleaning everything every time you refill the tank. That's probably the biggest issue with this humidifier, it takes quite a bit of maintenance.
