It’s winter, it’s cold, and worst of all, it’s dry. Excessively dry air can lead to a whole host of problems ranging from cracked skin to compromised immune systems. Luckily, humidifiers help to alleviate many of these issues. Unfortunately, traditional humidifiers can be clunky and bulky and not ideal for use in smaller spaces or while traveling.

Luckily, portable-sized humidifiers are gaining traction, which means you’ve now got quite a few options when it comes to moistening your air. Picking out the right humidifier you boils down to figuring out what exactly you need from it. In this guide, we’ll cover the things you should look out for. At the end, if you’re still stuck, we’ve also got a list of our 10 favorite portable humidifiers.

How to Choose a Portable Humidifier – Buying Guide

There’s no point in buying a humidifier that you’re not going to use. This guide will help you pick out one that’s exactly right for your situation.

Cool Mist vs. Warm Mist: Think About Safety and Water Purity

There are two main ways to produce mist: cool ultrasonic diffusion and warm vapor. Each come with their own pros and cons. Be sure to figure out the differences before starting to shop.

Cool Mist is Safer for Children and Animals but Requires Clean Water

Cool Mist is Safer for Children and Animals but Requires Clean Water

Cool mist humidifiers work by essentially flinging water particles into the air. This means that whatever is in the water (think minerals and microorganisms) also goes into the air, which may be a problem if you’re traveling somewhere with less than ideal water cleanliness.

Some newer models use low doses of radiation to kill bacteria, but minerals might still be an issue, and of course, it also depends on your feelings towards radiation.

However, these types of humidifiers also don’t heat up, which make them safer for homes with children and pets.

Warm Mist Gives Reliably Clean Vapor

Warm Mist Gives Reliably Clean Vapor

Warm mist humidifiers work by heating water to produce steam. Because the water is heated, any bacteria are killed, and because it works by vaporization, minerals are also not dispersed into the air.

However, as they heat up, these may be more dangerous. They also tend to be a little more expensive both on the buying side and in electricity usage.

Built-In Tank or Water Bottle? Depends Where You’ll Use It Most

All humidifiers need to get their water from somewhere, and what source you choose will depend on where you’re planning on using it.

For Home or Office Use, Go with a Built-In Tank

For Home or Office Use, Go with a Built-In Tank

Built-in tanks are more eco-friendly, so if you’re not looking to economize on space, it’s probably a good idea to go with a built-in. And while portable-sized tanks probably hold less water than a water bottle, you have reliable access to clean water at home and the office, so changing it shouldn’t be much of a problem.

When choosing a built-in tank, consider the size of the room that you’ll be using it in as well as how long you’d like to go between refills. For both of these, be sure to check the humidifier’s mist output. Higher outputs will work in larger rooms, but they’ll also use up water faster.

For Travel Use, Go with a Water Bottle

There are portable humidifiers that use water bottles as their water tanks. Not having a built-in tank automatically makes a humidifier smaller and more portable.

Of course, it’s less eco-friendly, but space is precious when you travel, and using bottled water is also a good way to ensure water purity. Water bottles also hold more than a portable-sized water tank would, which means that it will last longer on a single refill.

Batteries or USB Power Sources Work in Any Country

Batteries or USB Power Sources Work in Any Country

If you’re going to be traveling with your humidifier, the last thing you want to do is arrive in a new country and realize that it won’t work because of outlet size and voltage difference.

Save yourself the trouble and go with one that uses batteries or a USB charging port. You can buy batteries anywhere, and since most of our electronics work via USB, as long as you’re able to charge your phone, you’ll be able to charge your humidifier.

Intuitive Controls for Hands Off Usage: Auto-Off and Mist Control

Intuitive Controls for Hands Off Usage: Auto-Off and Mist Control

The automatic shutoff feature will turn off your humidifier once the water runs out, which is critical for the maintenance of your machine. So if it doesn’t go off by itself, you’ll have to be diligent about doing it yourself.

Some humidifiers also come with options to control mist output to increase the amount of time between refills. Others give you the option of having the mist spray in intervals.

Tips to Keep Your Portable Humidifier Clean

Tips to Keep Your Portable Humidifier Clean

It’s important to keep your humidifier clean so that it works well and gives off healthful spray. Unless your water is perfectly distilled, you’re likely to have some mineral build up, so you should be sure to give your humidifier a wipe down every few days. Once a week or so, you can use undiluted white vinegar for a deeper clean.

If you’re using a built-in tank, be sure to change your water at least once daily to prevent stagnant water and bacteria growth. Lastly, some tanks are dishwasher safe; however, those tend to only be the larger models.

Summary

So there you have it! You should now be able to figure out what you’re looking for in a humidifier, and maybe you’ve already got your eyes on one. Just remember to always use good, clean water and you should be set to go!
