Warm Mist Humidifier Reviews

1. Luma Comfort Cool and Warm Mist Humidifier

Luma Comfort HCW10B can operate for as long as 20 hours on a single tank fill and successfully humidifies a room as large as 538 sq. feet. It disperses both warm mist and cool mist. 

The design and style are completely different to other humidifiers. If I were to first look at it in just a few seconds, I probably couldn’t tell that it’s a humidifier with its shape and style. Not without examining closely the device.

Admit it, you’d have the same reaction as mine, too! But I like it. I love how it looks some kind of folder organizer instead of a home essential device. 

With the way it looks, it just wouldn’t be right if there’s no LED display, right? So there you have it, the LED display is made easier and clearer for readability purpose.

Another incredible feature is its demineralization cartridge that helps reduce the buildup of white powder. Meanwhile, you’d be doing lesser clean up on your part, too!

You can also sleep peacefully with the unit on since it is built with a 12-hour timer. Lastly, there’s also what they call, “SmartMist Technology” that will automatically store your preferred humidity level. Pretty cool!


  • Ultra-quiet operation
  • Auto-off safety feature
  • Removable tank for easy cleaning


  • Nozzle can cause water to pool on the floor

2. Rowenta Intense Aqua Control Ultrasonic 360 Humidifier

It includes three unique modes; automatic, baby and night mode. You can now enjoy a relaxing warm mist output and bacteria-free steam that can be increased up to 20%.

The unit comes with an electronic hygrometer that can show you the current humidity level and allows the humidity rate to be adjusted.

In situations where the tank is empty or the humidity level of the room has reached 90%, Rowenta HU5120 will automatically shut off. So no more of those annoying beeping empty tanks sounds!

Due to its 1.5-gallon tank capacity, the unit can function for one whole day continuously. The electronic controls and digital display enables you to have smooth access to the basic and important functions. 

A demineralization cartridge is also provided to filter the water mist from lime scale. Finally, it has a removable steam diffuser that can also be moved 360 degrees. 

Oh, and same as Luma Comfort, it functions as a warm and a cool mist option as well!

It consists of 3 settings; low, moderate and high. The digital controls are smooth and very easy to touch allowing you to choose a level without too much effort. 

Finally, the LED light is bright enough to be used as your night light. Which means, this humidifier can save you some energy since you can utilize it as your night light alone.

It is designed to shut off automatically when water is almost dried up or when tank is empty.

A refill light indicator is also added that will light up when the tank needs to be refilled again. Something I definitely prefer than those beeping sounds!

Moreover, this HWM705B is filter-free which only signifies that there would be less cleaning and filter replacements involved. Saves you some effort and money! How great is that?

And on top of all those features, this product comes with a medicine cup that can be used for liquid inhalant to provide you even more relief from diseases and infections caused by dry weather. Talk about a health advocate humidifier, huh?

5. Holmes Warm Mist Humidifier

This humidifier is created to hold around 2.3 gallons of water and only needs one refilling for one whole day. 

Just take note that HWM6008-NUM doesn’t work as effectively in large rooms than it does in small rooms, offices and nurseries.

What benefits can you get from a warm mist humidifier?

Before you’ve landed yourself on this review of mine, I’m sure you’ve already heard or researched some good things about a warm mist humidifier. 

Or perhaps you have some particular reasons why you chose this one instead of the cool mist humidifier. Am I right? 

I’ve also had my fair share of researching the internet on the benefits of a warm mist humidifier at our home or office. Both categories are remotely similar of the wonders they do to us.

Although cold mist humidifiers are more popular and frequently used than warm mist, but I believe the latter should be given as much appreciation as the former has.

So please allow me to share my findings on the pros of having a warm mist humidifier referencing it to our list for today. Here it goes.

  • For starters, it is considered to be one of the healthiest humidifiers in the market due to its hot steam’s strong ability to fight against any bacteria or mold from building a home in the device. 
  • This category is also quieter than cool mist because of the absence of fans. 
  • Lastly, it produces less minerals, thus, lesser white powder buildup. 

See? It does have its own set of remarkable benefits. Albeit, not as many as a cool mist humidifier, but still, equally awesome and effective in doing its job. 

Final judgement

If you’re the type of person who is overtly health conscious and is meticulous at the bacteria-killing factor, you’d best go with any of those a warm mist humidifiers considering the fact that the hot steam it releases is highly capable of performing this specific function.

Every humidifier on this review has its own unique features that sets it apart from the rest. It may not be the best of the “bestest”, but each one is definitely best on its own way. 

You never know, the cheapest and smallest humidifier might be the one that’s perfect for your needs and wants even if it’s not the best for others. 

And that, my dear friends, is absolutely normal and completely okay, and so I hope you find the best humidifier there is for you!
