It’s no secret that humidifiers can be a game changer for your health. Their benefits range from relieving coughs, and fighting asthma to moisturizing skin. Many people say that the gentle mist and hum of a humidifier even helps with insomnia. And some claim that it even prevents your chances of catching colds or the flu. Did you know that humidifiers also improve conditions for certain plants? It will do wonders for your tropical plants. We could put together a lengthy list of all the ways that humidifiers improve your life, but I think you get the picture. So if you want a break from coughing fits, if you are fed up with a runny nose, or if you just want to sleep better, try running a humidifier in your home. Odds are you will find yourself sleeping and breathing more comfortably with the increased moisture levels and ideal humidity a humidifier brings.
You may be wondering, why do I want a filter-less humidifier? Well the beautiful thing about filter-less humidifiers is that you’ll never have to replace a filter again so it saves you time and money. But the down-side is that you’ll want to clean it more often. Because of this I recommend only using distilled water, which leaves less build-up and residue. And if you’re wondering why you should get an ultrasonic humidifier (as opposed to an evaporative one), the answer is simple: ultrasonic humidifiers are smaller, send more moisture into the air, and are quieter than evaporative humidifiers. Let me give you some more pointers on what to look for in humidifiers.
What To Look For When Shopping For A Humidifier
In addition to looking for a humidifier that is both filter-less and ultrasonic, you’ll want to make sure it has these qualities:
- A rotating mist nozzle. This is a big deal because it allows you to redirect the mist away from items which you don’t want to become damp, such as electronics or upholstery.
- A warranty or satisfaction guarantee. You’ll have peace of mind knowing that your product can be replaced or repaired in case there are any problems.
- An appropriate size for your living space. Think about both the space the humidifier will take up and also the size of the room the humidifier will service.
- How long it can run between refills. Check the run time on our list below to find a product that will operate as long as you want it to.
- An opening conducive to cleaning. Make sure that the hole is large enough to fit your hand in so that you can thoroughly clean it between uses.
Now that we’ve discussed what to look for in a humidifier, we’re ready for our list of the best filter-less ultrasonic humidifiers. Let’s begin!

Vicks
Let’s start with a brand we all know and love: Vicks. This is a powerful humidifier that gets the job done! But don’t take my word for it: during a survey conducted earlier this year, researchers found that pediatricians most often recommended Vicks humidifiers.
This model has some really useful features, such as a dial to adjust the strength of the mist and auto-shut off when it runs out of water. It is easy to clean because it is equipped with a wide tank opening. This is a big deal for filter-less humidifiers!
Also, if you insert a Vicks VapoPad this humidifier will emit a soothing scent. Note that only one VapoPad is included, but they are sold separately and come in menthol, eucalyptus, rosemary, and lavender aromas. If you are looking for a humidifier for Covid, this is a great choice!

Homech
There is so much to love about this top-rated, ultrasonic humidifier! But the best part is arguably how quiet the Homech humidifier is when running. Babies and light sleepers won’t even notice it during the night thanks to its patented noise reduction system. A special cover reducing noise to 26dB when operating makes it one of the quietest options out there.
The Homech ultrasonic humidifier has such an intuitive, user-friendly design. For starters, the nozzle rotates 360 degrees and the mist reaches a height of 2 feet. This means you can better control the direction of the mist. Additionally, a built-in handle makes it easy to transport from room to room if needed. And it will show a low water warning then run for a few more minutes to drain the water.
I particularly appreciate the tall, long shape because it makes it easy to find a place for this humidifier, even in small spaces. Plus, the water gauge is transparent so you can see how much is left, which is very useful if you ask me.

You’ll see that it’s designed to accommodate your preferences in regards to the speed and direction of the mist. You can adjust it to a high or low speed setting and also rotate a nozzles 360 degrees to make sure it’s going in the desired direction.

Parents won’t have any reservations about putting the LEVOIT humidifier in a nursery or child’s room. It truly was built with safety in mind; it is BPA free, FCC certified, ETL listed, and ROHS compliant.
And LEVOIT boasts that their humidifier is so silent you can hear leaves fall even when its at the highest mist level. With a patented silencer, you won’t even hear the drip like you do on other humidifiers. Even light sleepers won’t notice it running at night. While many will appreciate the night light on this, I think it’s great that they provide an option to turn off all lights for those of us who prefer total darkness at night.
When you purchase this product, you’re supporting American workers! Although LEVOIT has offices all over the world, this humidifier was designed in California where their customer service is still based.

The makers of this ultrasonic humidifier patented a unique interior design to reduce water dripping sounds. Hence it won’t disturb babies or light-sleepers at night.
The water inlet is designed with your convenience in mind! It is 9 cm wide, large enough for easy filling and cleaning. This ensures you won’t spill while refilling and that you’ll be able to clean the entire tank with ease. And like other humidifiers on this list, it also has an optional night light and low water warning. The Miroco comes with a built-in handle, cleaning brush, and dust proof sponge.

What makes this humidifier unique is that the lid is removable so you fill it from the top. This makes refilling cleaning a breeze! This product from GENIANI also stands out from the others because of its built-in intelligent sensor. It automatically adjusts the mist but also allows you to manually choose a low, medium, or high setting. And it is equipped with an essential oil tray so you can enjoy your favorite aroma!
In my opinion, the GENIANI humidifier is one of the best options on this list. It is a little more expensive than others, but it has everything you’d want in a humidifier. I really don’t see any down-sides to this one. It truly is a risk-free purchase since it comes with a 2-year warranty!

Since it has a 24 hour run time, this machine provides gentle moisturizing mist all day long before anyone needs to refill it. You won’t need to worry about the humidity being evenly distributed throughout your house since the rotating nozzle will take care of that, too. All you need to do is simply turn it on and let it do its magic!
Although it is a smaller humidifier, the quality is still top-notch. It is quieter than a fridge or a computer, automatically shuts off when it’s out of water, has an anti-slip grip to move it around, and allows you to adjust the output according to your preferences.
In my opinion, this is the easiest humidifier to clean on our list. Due to a huge opening, your hand will fit in comfortably to wipe down the tank. Homasy designed it in such a way that you’ll be able to reach every nook. They even included a small brush to help you maintain the cleanliness of your humidifier.

TaoTronics
After one look at the TaoTronics humidifier I was sold! You’ll understand why once you see how sleek, modern, and stylish it looks. Visitors may not even realize its a humidifier since it resembles a vase. And I just have to say that I love that it has a vertical design to save countertop space. It isn’t that much bigger than water bottle.
But this humidifier doesn’t just have good looks, it also works great! With a nozzle that distributes the mist in 360 degrees, a dial knob to regulate the mist, and an auto shut-off, it will meet all of your needs.
TaoTronics took extra measures to make this humidifier extra safe. Not only is it made of BPA-free materials but it’s also FCC certified. This means you won’t have to worry about any harmful effects. Just keep in mind that it is best suited for small rooms since it only holds half a gallon of liquid.

Crane
Like any humidifier worth purchasing, this one allows users to adjust the output settings including the mist direction and intensity. Also, it runs all night long and is equipped with an auto-off feature. Best of all it contributes a sleek, polished aesthetic to your living space and even comes in several color choices to perfectly match.
One aspect that makes the Crane humidifier stand out is that it is made with clean control anti-microbial material. This is a big deal because it nearly eliminates growth of mold and bacteria. Even so, it is still recommended to clean the fill tank frequently. Crane provides instructions on how to maintain your humidifier’s cleanliness.
With that said, there are a few things to keep in mind. For instance, some people have noticed that it leaks and gets loud after it’s been used for a while. But all in all it is a great value for the price!

FAQs
What are the health benefits of a humidifier?
A humidifier can help open air passages and make breathing easier, especially for those who are ill. Many doctors recommend using a humidifier to reduce couching and other effects of colds and flus. A humidifier can also provide moisture for dry skin.
How does an ultrasonic humidifier work?
An ultrasonic humidifier uses vibrations to disperse water droplets from the water reservoir into the air in the room. Even though the vibrations occur at a very high frequency, an ultrasonic humidifier is actually a very quiet machine. It is considerably quieter than most evaporative humidifiers.
Is a filterless humidifier better than one with a filter?
A filterless humidifier is less expensive in the long run because you don’t have to buy replacement filters. However, with a filterless humidifier, you do have to clean it more often. Most people prefer filterless to a humidifier with a filter.
