MistAire XL Humidifier Review: Does XL Mean For Larger Rooms?


Since the time I have done the review of the MistAire Ultrasonic, which I bought for my kids’ room, the thought of getting another humidifier for our bedroom has lingered in my mind. I mean, getting a full-home humidifier was also something I was thinking about. But, in order to humidify the entire home, I would need a super-strong model, and those are quite expensive. And, the room in which the humidifier would be placed, would be properly humidified. But, you can never have all the rooms equally covered with mist. Therefore, I decided to find a powerful whole-room humidifier and my choice landed on the brand I already use. This time, I bought the MistAire Ultrasonic cool mist humidifier XL for Large rooms.


It is pretty much the same model as my old MistAire, only bigger and capable of covering larger areas.

Some of you might think: “Why didn’t she just opt for the same model as in the kids’ room?”.


And, to be honest, I was thinking about getting the same model. But, wasn’t sure if it would be strong enough since my bedroom is twice the size of the kids’ room.


It would be nicely humidified with my old MistAire, but not as much as I need.


To make sure I wasn’t making a mistake, I did a comparison test and compared all the important specs.

Water Tank Volume-

​As you can see, the MistAire XL tank is bigger than the MistAire tank for more than a double. This means that in theory, you would have to refill the XL fewer times.

 

But, in reality, this tank difference is not there because the XL will offer drastically longer run times, but because it needs more water available to push out more mist.

And, this wasn’t the main reason why I decided to go with the XL.

Run Time on Full Mist Settings-

​On the other hand, run times on full mist was something that I was interested in finding out.

 

So, the table shows that the XL can run 10 hours of full mist settings.

 

While, on the other hand, on the high mist settings, my old MistAire can run 8 hours tops.

 

This meant that I would have  2 extra hours to start running the XL before bedtime so that when I do enter the bedroom it is already nicely humidified.

This was the first important point for the XL.

 

As for lowest mist setting, the XL is again in the lead as it can work 24 hours on one tank.


While, on the other hand, the MistAire has max 16 hours of running on one tank when the mist is set on a minimum level.

Auto Shut-Off-

​This is a feature that I really enjoy because it allows me not to worry about leaving the humidifier to run on its own.

 

And, as I already knew that this works quite nicely on my old MistAire, seeing that the XL model also comes with Auto Shut-Off made me happy.

 

As far as this goes, both models are reliable and can be left to run without supervision.

Coverage Area-

​This was the most critical spec, and I had to make sure I was getting it right.

 

As you can see in the table, my old MistAire is powerful enough to cover some 300 square feet.

 

Having in mind the good old rule “Always choose a humidifier that has a bigger coverage area than the room you plan using it in.”, and, since my kid’s room is below 300 square feet, the MistAire is a great choice.

 

However, my master bedroom is over 300 Square feet and the XL model can cover up to 500.

 

So, it was a logical choice. Not to mention the fact that it has just a two-hour longer run time with double the size of the water tank, which means that it can pump out some serious mist.

Mist Level Adjustability-

​This was the point that made my mind say: “Okay, XL it is!”

 

With the MistAire you can only choose between High and Low.

 

There’s no middle or near full mist, or somewhere between medium and low… 

 

On the other hand, the MistAire XL comes with an adjustable knob.

 

This means fine-tuning the mist output exactly to the desired level, and I needed that!

 

As you can see at the end, there were more points on the XL’s side.  Therefore,  without a doubt in my mind that it would not be a good choice for my master bedroom, I ordered it. Here are my impressions after it arrived and I got to take it for a spin.

 MY REVIEW: HERE’S MY THOUGHTS AND OPINIONS ON my

    MISTAIRE XL ULTRASONIC humidifier

A week or so after I ordered the MistAire XL Ultrasonic Humidifier, a nicely packaged box arrived at my doorstep.


So, you know how when you order a bunch of stuff from Amazon, you tend to get forget what you ordered, and each delivery feels like Christmas?


Well, this was the case with the big box, but once I opened it, and realized it was the new, BIG humidifier, I became eager to plug it in and see the mist.


And, I am happy to tell you it delivered far better than I expected!


After checking if the water tank is undamaged and that the unit itself feels intact, I rinsed the tank with hot water and got it filled up to the top.

Easy use and effectiveness?

The water tank is nicely built and easy to fill, however, keep in mind that it can take nearly 4 liters so holding it, might become hard.


The next step was plugging it in and checking if it works. I turned the mist know to the max (as much it allowed me to turn right).


Right from the start, it started pumping out nice, dense mist and the air immediately became more comfortable to breathe.


The test run plan was turning the humidifier on, some 2 hours before bedtime, so I placed it on the night table around 10 pm and left it like that.


And, around midnight when my husband and I entered the bedroom, we noticed that the whole room was really well humidified and that there was a night of a restful sleep ahead of us.


When we woke up, some 9 hours later, the water tank had about a centimeter of water in it at the bottom, and the humidifier was turned off.


So, here are my thoughts after a test run of some 10 hours.

MANUFACTURER CLAIMS
VS
REALITY TEST

As always, after giving the humidifier a test run, it’s time to see how true are the manufacturer claims.


Here is what I discovered about the MistAire XL Ultrasonic Humidifier for large rooms.

LONG-LASTING RELIEF-

This is true right from the start. 

The Ultrasonic cool mist technology used for this model allows you to have a nice, safe to breathe mist for up to 10 hours if set on the highest mist output setting.

 

In my case, it nicely puffed fog all night long and both my husband and I woke up in the morning well rested, without dry noses or the throats. Here is an article that will explain how important it is to sleep in a properly humidified room.

 

In our case, heavy sinus problems demand “heavy” mist and we always run the humidifier on the highest settings.

 

However, if you need less mist and use the minimum setting, you can get some 24 hours of run time from just one filling.

1 GALLON WATER TANK-


Again, true. The water tank can take in up to 3,78 liters (1 gallon), and will comfortably humidify rooms that are up to 500 square feet big.

 

Our bedroom is around 40 square feet in size and we had some 10 hours of excellent humidification with one full tank.

OPTIONAL NIGHT LIGHT-

When it comes to the “light show” the ultrasonic cool mist humidifier XL model comes with, considering that it was meant for the master bedroom, I wasn’t looking for a “Pink Floyd” concert effects feeling and this feature wasn’t all that important for me.

Different night lights!

 

But, having a nice, not to bright night lamp, actually does brighten up the room to a comfortable level you can sleep in without a problem.

 

And, I also liked the fact that you get to choose one color (red, green, or blue), and it keeps it in that color until you decide to change it.

So, there’s no light switching throughout the night, which would be useful for making the baby calm and focused on the light show, but quite distracting for adults.

 

Or, you can simply choose not to have light at all if you are too much of a light sleeper.

AUTOMATIC SHUT-OFF-

​​​Another true claim and I couldn’t be more grateful for it. I cannot emphasize enough how important this feature actually is. 

You can leave it to run on its own whenever and where ever you want, and put your mind at ease because it really shuts down on its own when it’s nearly empty.

 

As I mentioned above, after some 10 hours of running on full mist setting, it simply turned off on its own.

 

The next step will be running it on the lowest mist output setting and testing the 24 hours run time claim of the manufacturer.

 

But, considering that I got 10 hours on the high, I will most likely get some 20 to 22 hours, which is also not bad.

 

It will allow me to leave it running the entire day while we are out and about, and have a relatively nice level of humidity in the home when we get back.

 what's included in this

    MISTAIRE XL ULTRASONIC humidifier

When I opened the box, here is what was waiting for me on the inside:

  • Humidifier
  • AC power adapter
  • Disk cleaning brush
  • User manual
  • 5 Year Warranty document

So, as you can see, there are no accessories, but then again, the model is really easy to use and doesn’t need additional parts to run smoothly.


However, I would suggest getting demineralization solutions for the cleaning times.


Furthermore, the manual is nicely written and offers clear instructions for every important aspect.


And, it also shows how to properly clean it, with the included disk cleaning brush.


Make sure you follow those instructions as proper maintenance will prolong its lifespan, as well as maximum functionality while it works. Check my other article if you need help with humidifier cleaning procedure.


Finally, the MistAire Ultrasonic Humidifier comes with a 5-year warranty, which is always a good thing to have in case something goes wrong in the meantime.


And, if needed, you also have responsible customer support 7 days a week at your disposal.

pros & cons

Like any other model, this one also comes with both Pros and Cons, but in this case, cons are not even close to being deal breakers.

  • Pros
  • cons

pros

  • Impressive power and mist output levels
  • Easy to use and maintain
  • Almost completely noise-free
  • Automatic Shutdown

As you can see, the pros outweigh the cons by a mile and this model is definitely a great one for home use, when you need one larger room nicely humidified.


The only downside I discovered is that the water tank is a bit demanding when it comes to refilling as you need to hold it all the time.


Sounds easier said than done, considering the amount of water it can take in.


But, this definitely wasn’t a deal breaker for me, and I am pretty sure most of you won’t mind working on your arm muscles a bit, right?

 MY RESULTS FROM THIS

    MISTAIRE XL ULTRASONIC humidifier

So, in conclusion, here is what I managed to get from my new MistAire XL Ultrasonic Humidifier.


It can definitely humidify a large room without a problem. And, on max setting, it will start pumping out serious amounts of mist.

And, if your room isn’t that big, you will probably have to set it to a lower setting. Because you will soon have a feeling that you are in a jungle. 


Yes, it is that powerful.


A powerful blast of mist when it's on max setting.

Once you figure out which settings work the best for you, your mornings will feel much, much better than before.

 

In my case, I can even say that I started feeling better in the morning than I was with the old humidifier.

 

Don’t get me wrong, I love my old humidifier and it also gets the job done exceptionally well. But, I can’t sleep in the nursery room every night because it doesn’t perform well in bigger rooms.

 

However, with the ultrasonic cool mist humidifier XL model, I have a feeling and will test that out pretty soon, that even if I used it in our biggest room, the living room, it would still be able to cover the entire area without a problem.

 

Last, but not the least, the auto shut-off feature works flawlessly, and eases your mind more than you actually think.

final words?

Mistaire XL Humidifier

MY REVIEW-

This humidifier is definitely suitable in any rooms that are below 500 square feet! It gives the flexibility to tune the mist settings according to the room size as long as it is below 500 square feet. 

This is suitable for my master bedroom due to a slight larger room space.

However, this might not be powerful enough to churn out mist for more open-spaced rooms such as my living room and dining halls.

You might need to have 2 or 3 of these humidifiers to churn out enough for these large open-spaced rooms, which require more time and effort to clean!

This sure has a slight advantage over price as compared to the smaller version of this humidifier( since it can produce more mist per unit price.) Overall, I would rate this as 3.5 star rating!

​So, for those who have problems with dry air, or respiratory issues, this model might be a great choice.

 

I mean, you don’t actually have to use it in a big room. But, having the opportunity to really mist it up when you need it, regardless of the room size, is a quite nice option.

 

Of course, as always, my review is based on what I experienced with this humidifier. This means that it might work differently for other people.

 


Once again, feel free to share your personal experience with this model if you are already using it. Or, in case you are about to order it, make sure you let us know how happy you are with it.
