Levoit Top Fill Cool Mist Ultrasonic Humidifier Best for Silent Operation

Features
  • Mist type: cool mist
  • Water tank capacity: 1.8 L
  • Mist time: 8–20 hours
  • Coverage area: up to 260 sq. ft.
  • Essential oils diffuser: yes
  • Dimensions: 7 x 7 x 10.6 inches

More features: 3 mist speed settings, BPA-free, quiet operation

The first thing that you notice about this humidifier is the small footprint it has. It takes up very little space and that makes it ideal for placing beside a bedside table. The 7×7” measurements give it great versatility of placement.

The downside to that smaller size is that the tank capacity isn’t going to be as high. At 1.8-liters it is smaller than many of its rivals. That being said, at the lowest setting, it will still be able to run for 20 hours so you won’t have to constantly top it up.

Another aspect that makes this great for bedtime is that it has an almost silent operation. The humidifier is going to enable you to get to sleep with the cool mist and your sleep isn’t going to be disturbed by any sounds.

Usability on this model is very high and you’ll be able to run it without any frustrations. There are three different speed settings for your perfect humidity. There is also a smart sleep function that’ll turn off all the lights and keep the humidity at a comfortable level.

With its top-fill design, this is one of the easiest humidifiers to top up with water and you’ll be able to do it with no mess. Despite it being quite a tall model, stability is very high and it won’t easily be knocked over. Other great features include being able to use essential oils and also its automatic shut-off function. It all adds up to a brilliant humidifier.

Pros
  • Almost silent
  • Simple to refill
  • Good stability
Cons
  • Fairly small tank
5.

Honeywell HCM350WBest Evaporative Humidifier

Features
  • Mist type: cool mist
  • Water tank capacity: 3.8 L
  • Mist time: 24 hours
  • Coverage area: 300 sq. ft.
  • Essential oils diffuser: no
  • Dimensions: 17.9 x 9.37 x 11.4 inches

More features: wicking filter, UV technology, excellent for babies, children and adults

If you wanted a humidifier that looks great then this is going to be a great option for you. It has a stylish design that will look great wherever you put it in your home. Being able to see inside the tank will also show you when the water is running low.

One of the key features of this humidifier is that it uses UV technology. That UV light will kill off any bacteria in the water. It means you know the water coming out of the machine is going to be completely safe to breathe.

The water tank capacity is 3.8-liters which many people are going to see as a perfect balance. It still doesn’t take up much space while being able to deliver a high volume of mist for a long time before it needs to be refilled.

The mist that comes out of the humidifier isn’t visible and also won’t cover everything around it in condensation which can be an issue with some other models. The only real downside here is that the filters are fairly expensive.

Usability is very high as the device is fairly simple to use. It’s also easy to clean and maintain to keep it as healthy as possible. It’s a world-class model and one that can easily make any room your home a lot more enjoyable and easier to breathe. 

Pros
  • No visible mist
  • Large tank
  • Easy to clean and maintain
Cons
  • Expensive filters
Features
  • Mist type: cool mist
  • Water tank capacity: 1.5 L
  • Mist time: 16 hours
  • Coverage area: 250 sq. ft.
  • Essential oils diffuser: no
  • Dimensions: 8 x 6 x 9 inches

More features: optional night light, automatic shut-off, 5-year warranty

Pure Enrichment has made a humidifier with a unique shape that many users are going to love. A part of that design is a transparent water tank which is always useful for knowing exactly how much water is left in there.

In terms of that water tank, it can hold 1.5-liters which is on the lower end of the scale. That makes it ideal for the likes of bedrooms where the coverage area is a little smaller and you’re not going to need the same level of coverage.

One annoying aspect of this humidifier is that it makes an obnoxious beep when you change the settings and there is no way to turn it off. It seems like a pointless feature and one that doesn’t serve much of a purpose.

One great feature is that the base can fully detach which makes filling up and cleaning exceptionally easy. While the beep is annoying, the humidifier is almost silent when it’s in operation and is not going to disturb your sleep.

The night light is another feature that can be very useful, especially if you want to use the humidifier in your children’s rooms. All of this quality is backed by a 5-year warranty and therefore you can have full confidence that this is going to stand the test of time.

Pros
  • Base can fully detach
  • Great night light
  • Whisper quiet
Cons
  • Annoying beeps
Features
  • Mist type: cool mist
  • Water tank capacity: 6 L
  • Mist time: 100 hours
  • Coverage area: 215-430 sq. ft.
  • Essential oils diffuser: no
  • Dimensions: 17.8 x 11.6 x 7.7 inches

More features: boil-dry protection, quiet operation, easy to clean, 360-degree rotatable nozzle, powerful fan

Capacity is one of the key factors on humidifiers and if you wanted the largest one out there then you’ll love this model. At 6-liters, it’s going to be able to pump out a huge volume of water and increase the humidity throughout your home.

Due to that incredible size, the humidifier will be able to run for a very impressive 100 hours. You’ll be able to put it on and not have to worry about topping it up for days on end. There is an obvious downside to that tank capacity and that is size and weight.

Wherever you put this humidifier, it’s going to take up a huge amount of space and also be very difficult to move unless it’s empty. A great feature to prevent you from needing to move it is the 360-degree nozzle to get it exactly where you need it.

Despite having a fan that will be able to disperse the mist, the unit is going to be able to stay very quiet. If you do forget to fill up the humidifier when it’s running low then it’ll shut itself off to prevent any accidents from happening.

This is an ideal humidifier for anyone needing to add mist to a wide-open space and needs a huge level of coverage. It will also be able to work very quickly and you’ll notice the difference in no time at all. The machine is incredible and can produce impressive results constantly.

Pros
  • Huge capacity
  • Ideal for large rooms
  • Works quickly
Cons
  • Bulky
Features
  • Mist type: cool
  • Water tank capacity: up to 0.6 L. (bottle)

You can take the Fancii Cool Mist Personal Mini Humidifier with you on any trip as its compact design fits into any suitcase or backpack. It even goes undetected from the ruthless eyes of TSA agents. It is powered by battery or USB cord, which allows for even better functionality.

The timer on this humidifier allows for different increments of two, four, six, and eight hours. There is also an automatic shut-off for peace of mind. This means that once the water runs out, there is no need to panic as it will safely turn off on its own.

The noise level is less than 15 dB which is whisper quiet. There is no worry that the Fancii Cool Mist Personal Mini Humidifier will take over any space. It is quiet, unassuming, and very advanced; you may purchase it for its innovative design, but you will keep using it because it works.

Buying Guide

Before you commit to the best humidifier for asthma, it’s important to know all the different features a machine can have. Even if a particular humidifier sounds great, if it doesn’t meet your needs, then it’s not worth purchasing it. Read on to learn more about what specific features humidifiers have as well as a few commonly asked questions.

Why do people with asthma buy humidifiers?

7532 3

When you have asthma, the airways that supply oxygen to the lungs become constricted. This makes it harder to breathe and can lead to wheezing and even coughing. At night, you want to be able to get a good night’s sleep, and the inability to breathe can significantly impact this. A humidifier outputs extra moisture in the air which will make it easier to breathe. The extra moisture softens the airways, putting less stress on the delicate tissues. As well, when air has more moisture in it, it also means that it will have more oxygen in it. This means the lungs don’t have to work as hard, giving you a much more peaceful slumber.
Keep in mind that these devices can not only help with asthma. Many people buy humidifiers for dry skin hydration, especially during the winter season. Others use humidifiers for cough and sinus problems relief. In a word, these devices are so versatile you can't help but getting one.

Features to consider while choosing a humidifier

There are many features to consider with a humidifier. Read on to learn more about what differentiates one product from another.

Mist type

Humidifiers can produce either cold mist, warm mist, or the option of either. Cold mist is nice and refreshing in the summer, but warm mist is particularly comforting in the winter. More often, humidifiers are used in colder months, during cold and flu season, so it’s always nice to have a humidifier with the option of warm mist. Be aware that if you plan on using a humidifier in a large room, office, or whole apartment, by the time the air particles get to you, chances are they will be room temperature.

Water tank capacity

A water tank capacity is vital for two reasons. First, the larger the tank, the larger the humidifier. If you have a small space like an apartment, then you will want a smaller humidifier, and smaller water tank. If, however, you need a humidifier for a large room or even an office, then there will be space for a water tank with a bigger capacity.
cool-mist-ultrasonic-humidifier-white-tank tg
Water tank capacity also reflects just how often you need to refill the humidifier. Small water tanks mean having to refill more often. If you just want a humidifier to be on for a few hours, then a small tank will suffice. If, however, you want your humidifier to be on all night long, be sure to find a water tank that will last. Otherwise, you will have to make waking up to refill the tank part of your nightly routine.

Mist time

Mist time refers to how long a humidifier can last before the water runs out. There are usually a few settings on a humidifier, so even if a product states that it can last 24 hours, this may be just at the lowest setting. If you set the humidifier on high, then the water could run out in only 12 hours.

If you plan on using your humidifier at night, then be sure to select a product with a mist time of at least 10 hours. This should guarantee that it will still be running as you wake up.

Coverage area

The coverage area of a humidifier refers to the square footage of a room that the humidifier will work in. Some humidifiers, like the InvisiPure Alta Cool Mist Humidifier and the Fancii Cool Mist Personal Mini Humidifier are best for areas under 200 square feet, a small living room or bedroom. Other humidifiers, like the Bizond Ultrasonic Humidifier can be used in large rooms, and even whole apartments.

Noise level

There are those that need the gentle hum of white noise to fall asleep. There are others that will snarl like a dog if anyone dares to even whisper at night. Each humidifier has a different noise level, and this can be one of the most important features to consider as it all comes down to personal taste. Those that like quiet should consider a humidifier which produces less than 30 dB of noise.

Essential oils diffuser

Essential oils are all the rage right now. Not only do they smell pleasant, but they also can help calm emotions and relax after a hard day at work. If you are interested in essential oils, invest in a humidifier that has the option of also being a diffuser. This way you can save both money and space as you won’t need two large machines in your room. Products such as the InvisiPure Alta Cool Mist Humidifier and the Everlasting Comfort Ultrasonic Cool Mist Humidifier can be used as diffusers.

Dimensions

Small humidifiers take up less space, but also have much smaller water tanks. Therefore, they will not last very long between refills. Large humidifiers take up more space, but their mist time is longer. Most humidifiers are medium-sized. They are meant to be placed on a table or shelf and are usually not higher than 12 inches.

If you have a particular space that you envision your humidifier to be, be sure to measure and compare with the product features.

Extra features

There are many additional features that a humidifier may come with. As they are machines, a warranty is always a bonus. Most will come with a one-year warranty, but be sure to check what the customer service is like should there be any issues.

Humidifiers produce moist air, but they also work to purify it. In this case, a filter will need to be changed. It’s always a nice bonus when extra filters are included as it cuts down on the overall cost. Try to find out what type of filters is needed and how convenient they will be to replace in the future.

Most humidifiers are electrical, but some smaller ones are battery-operated. Check to see if a humidifier comes with these batteries or if you need to purchase them separately.

Finally, one of the coolest extra features of a humidifier is if it can also act as a nightlight or mood enhancer. Calming LED lights mean the humidifier can be displayed front and center in your room. It can also serve as a reassuring nightlight for an anxious toddler.

FAQ

Yes, humidifiers are safe for both babies and small kids. In fact, they are increasingly becoming a staple in most nurseries. If you have a baby that wakes often or seems colicky, then a humidifier can be an easy remedy. The same goes with small kids as their natural curiosity usually leads to sticky fingers and a whole host of newly acquired germs.

Be sure to keep a humidifier away from small kids, perhaps on a high shelf or bookcase. The hot steam produced could burn their delicate skin. What’s more important, though, is to hide any cords. Even if a humidifier is out of reach, a toddler could quite easily pull on the humidifier and have it tumble down. Hide the wire or invest in a simple baby-proof cord wrapper.

Animals, such as cats and dogs, often have similar health issues as humans, including asthma. While not always diagnosed, if you observe that your cat or dog wheezes or coughs a lot, then try using a humidifier to help them breathe. Humidifiers are also great in winter if your pet has dry, scratchy skin. The extra moisture from a humidifier can help your pet feel more relaxed and comfortable.

Humidifiers usually produce hot steam. While this isn’t as severe as boiling water, prolonged exposure can react badly to the skin, especially with children. Always place a humidifier out of reach of children. Make sure the cord is hidden or secured. Most humidifiers will have an automatic shut off if the water reservoir becomes dry. It’s important, though, to monitor this and get into the routine of refilling the water on a regular basis. Finally, make sure that the humidifier is on a secure shelf. It is a large object, and can really hurt someone if it were to fall off a shelf.

Our Verdict

There are nine humidifiers that made our list, but three that rose to the forefront. The Bizond Ultrasonic Humidifier is a great humidifier. It helps eliminate bacteria from the air and purifies what you breathe. It is sturdy, has a large tank capacity, and works well even in a master bedroom.

The best humidifier without a filter is the Everlasting Comfort Ultrasonic Cool Mist Humidifier. While its technology does purify the water that is released into the air, it doesn’t need a filter to do so. This leaves a lot less effort and money which is a great combination.

The third product on our list that can be considered the best humidifier for asthma is the InvisiPure Alta Cool Mist Humidifier. By releasing a soothing cool mist in the air, this humidifier works to calm the airways and bring more oxygen to the lungs. It is a great find and a purchase you won’t regret.
