10 Best Portable Humidifiers in 2022 (Pure Enrichment, URPOWER, and More)

Cool mist humidifiers work essentially by dispersing water particles into the air by one of two ways: ultrasonic or evaporation. Evaporative humidifiers use a fan to turn the water into a mist and have a wick filter that keeps bacteria from escaping into the air. However, the fan can make noise so keep this in mind.

The ultrasonic option uses frequency vibrations to create water droplets that emit in the air by a small fan that makes minimal noise compared to the evaporative ones. Make sure to use only distilled water, as others that are full of minerals can create dust if not cleaned properly. 

If you have children or pets, a cool mist humidifier will be a safe option since it does not use heat, reducing the chances of getting burned. You also don't have to worry about using too much energy as these are more conservative electricity wise than humidifiers that use warm vapor.  

The downsides to using cool mist are that it tends to accumulate bacteria growth and can be noisy compared to the warm mist option. Just be sure to clean your humidifier regularly to lower the chances of mold!

Warm mist humidifiers work by heating water to produce steam. Because the water is heated, it reduces the amount of bacteria and germs which in turn, makes it easier for you to maintain its cleanliness. During winter months, it may serve a great benefit to have the warm vapor to help warm the cold air as well!

However, as they heat up these may pose a threat to kids and pets since they may get burned if they are in close proximity or knock it over by accident. They also tend to be a little more expensive both on the buying side and in electricity usage.

Tanks are eco-friendly with no use of plastic bottles. They hold up to 350 milliliters of water, with the exception of larger ones that can hold as much as a standardized bottle of 500 milliliters. If you are home, this may not be an issue since you can refill as much as you'd like; but if you travel, you may want to reconsider a tank. 

Some things to note are the size of the room, how long you’d like to go between refills, and of course, how dry the air is and how much moisture it needs. The best way to go about this is to check the humidifier’s mist output, which is the amount of milliliters of water that is dispersed per hour. 

For a large room with extremely dry air, you can go with a higher mist output. It produces a greater amount of mist over a short period of time; however, it uses water at a faster rate. Lower mist output is suited for smaller spaces that do not need over-saturation, but instead maintain the moisture needed for a longer period of time. 

For either levels, these factors can vary if set on continuous or interval mode. Continuous mode allows more output in a short amount of time without breaks, whereas spraying in intervals would spread the amount of mist over your ideal amount of time, possibly increasing time in between refills. It's truly up to your preference! 

If you live to travel and want to maintain your health while doing so, portable humidifiers that use water bottles as their water source could be your move. Not having a built-in tank automatically makes a humidifier smaller, more portable, and ultimately frees up space you need. 

While it may be resourceful on-the-go, it is less eco-friendly as it can increase plastic bottle use and possible waste. Depending on your lifestyle of recycling and reusing the water bottle, this may or may not be a deal breaker.

On the other hand, using bottled water can ensure water purity and give you more leverage and versatility to choose the size of the water source. This could range from a standardized water bottle that holds 500 milliliters or a small bottle that holds 236 milliliters.
