Best Desktop Humidifier for 2022

So, how do you create a happier workspace despite the appalling air dryness brought by the vicious winter weather?

For me, a desk humidifier works wonders in elevating air humidity and I have certainly been a happier soul during winter months since I discovered these devices.

What’s more, since they’re so compact, you can carry it to anywhere your schedule takes you including to a winter camping trip.

Here we bring you desk humidifier reviews and show you how to choose the right one for your needs.

Hopefully, you will start to love your office, bedroom, car, tent, condo, hotel room, flights, etc. a little more and embrace the icy-cold, grey weather.

Why Desk Humidifiers?

Are you a budding humidifier for desk buyer? Here is what is in store for you:

These devices are incredibly small and lightweight and give you the ultimate portability.

To me, this is the star attraction in these models.

Of course, other humidifiers types, for example, console humidifiers are often larger and take up more desk or bedside table real estate.

I can’t imagine you packing them in your purse, backpack, or suitcase (a desk humidifier easily fits in any of these!).

Most importantly, they work perfectly and will put out the necessary amount of mist to alleviate the dryness in your environment.

In fact, most have all the sophisticated features you get in premium models such as timers, auto on/off, remote control, and more.

Never mind that they come at a much lower price.

You get it?

How does a Desk Humidifier Work?

A desktop humidifier moistens the air best in small spaces and will bring the optimum moisture level (EPA recommends 30-50%) to help you breathe easy.

But how do they work?

Now, no matter the model, the devices have a conventional design and make use of individual water reservoirs to produce mist.

A filter may be built-in to help purify the water (by removing particles and bacteria) before it is dispersed into the air.

They’re quite versatile and can be powered from standard electrical sockets or batteries.

They’re not heavy energy consumers and can last up to 18 hours (sometimes more depending on the batteries).

The other option is you plug it into a USB source like a laptop, power bank, and more (for some).

They typically include a wall adapter and required cables.

Types of Desk Humidifiers

The one place your desk humidifier may differ from mine is in the mechanism it uses to moisturize.

But by and large, they adopt the technologies used in other types of humidifiers.

So here are four different types of desk humidifiers you can enjoy a more comforting winter with at work.


Evaporators have fans blowing a moistened filter to expel the humidity (by evaporation) creating comfy precincts.

They can be a bit noisier because of the blowing action from the fan although lately manufacturers have devised myriad inventions to silence them.

Steam vaporizers

These heat water, cool it, and finally let it out as steam into the air to improve its quality and combat the harsh results of dry air.

They’re in truth very basic and are hence super inexpensive.

ltrasonic humidifiers desk humidifiers

Ultrasonic humidifiers make and release a cool mist in the immediate vicinity using ultrasonic vibrations.

An ultrasonic desktop humidifier is ideal if you have pets or children around (no heating and won’t burn your son/daughter on touch).

They’re also virtually silent.

Impeller desk humidifiers

Impeller humidifiers bring about mist using rotating disks (running at breakneck speed).

This technology again makes them inexpensive and pet-friendly (they dissipate cool mist).

Cool and warm mist in desk humidifiers explained

You must have noted my repeated mentioning of the term warm/cool mist when explaining the types to desk humidifiers and it is important you understand the implications of experiencing either type of mist.

To begin with, steam vaporizers humidifiers spew out warm mist- these units first boil water using a built-in heating element before circulating it into your space as a calming, unseen mist.

Because of that, you might feel somewhat warmer (and more cheerful) in the winter.

On the converse, evaporative and ultrasonic desk humidifiers discharge cool mist (no heating).

This simply means that the mist spreading throughout your space is at room-temperature and is often ultra-fine and, therefore, invisible.

But which mist is better?

Okay, as previously mentioned, cool mist humidifiers are ideal if the room you’re planning to keep the desktop humidifier is visited by children and pets (they won’t cause burns).

On the other hand, warm mist humidifiers tend to suit the more extreme northern winters better because the warmer feeling make winters more bearable.

These are the most important situations to have in mind in our opinion as far as the two most types are concerned as they are both equally effective in moisturizing the air.

Desk Humidifier Buying Guide

How do you decide which desk humidifier is right for you?

Well, you’ll need to consider:

  • Area covered- How big is the square footage of the office or bedroom you plan to moisturize?- the coverage is shown in the product label. (For bigger rooms go with humidifiers for large rooms)
  • Budget- mini-sized humidifiers are the least expensive yes but the price tag still differs significantly.
  • Maintenance- the less the required maintenance tasks like cleaning and water refilling, the more convenient it is.
  • Ability- does it deliver adequate mist? And can you redirect the nozzle to have mist reach across the room? 
  • Sizing- some have a bigger footprint and take up more space.
  • Noise- appliances with fans are slightly louder than fan-less models.
  • Ease of use/setup– you want one with straightforward controls and assembly.
  • Extras– features such as a slot to add essential oils could be amazing to have as your space will smell yummy! Automatic shut-off is another cool feature to look out for if you chance to leave it on.
