Choosing the Best Personal Humidifier

A personal humidifier is meant to humidify the air around you, not to cover large areas. But with so many mini humidifiers available on the market, how do you choose the best one for you? We’ve listed a few things to consider before buying a personal humidifier.

Tank Capacity

Personal humidifiers aren’t big, and can, therefore, not hold as much water as regular units. However, it’s still important to figure out what tank size would suit you.

Consider where you’re going to use your personal humidifier — do you need it in your office? Or maybe you need it on your nightstand. These locations will require a larger capacity to give you more time in between refills.

On the other hand, if you need a humidifier in the car during short drives, for instance, a smaller tank will do.

Keep in Mind

A larger tank will give you a longer running time. However, consider how often you’re willing to refill it.

Safety

Most regular humidifiers are fitted with an auto-shutoff feature to protect the device from damage when the water runs out. However, mini humidifiers are simpler in design; therefore, many don’t feature this safety precaution.

Choose Auto-Shutoff

Because the tank is smaller, it will run out of water quicker. This means the risk of dry-burn is higher. We recommend that you choose a device with an auto-shutoff feature to protect yourself and your humidifier.

Portability

The best personal humidifier has to be easy to operate wherever you go. We aren’t always near a wall outlet, so consider how the humidifier is charged. Fortunately, most mini humidifiers include a USB cable that you can attach to an adapter, PC, laptop, phone, or power bank.


The Best Personal Humidifier Reviews of 2021

Finding a personal humidifier is easy. However, finding the best personal humidifier can be challenging. As we searched through the top-rated devices, we considered how well each humidifier would perform in different locations.
