Best Humidifiers In 2021

Do you live in a super dry climate? Are you having a tough time getting through the day without your best lotion and best chapstick? Maybe you have bad seasonal allergies and are prone to getting colds. If that’s the case, you need top humidifiers.


If any of this sounds familiar to you, then finding the best humidifiers to use in your home might just sound like a great idea. What should you know about them, though?

When you’re shopping for humidifiers, you have to choose either a warm mist humidifier or a cool mist humidifier. You’ll need to consider the space you’ll be using it in as humidifiers have a range for which they can add moisture into the air. The size of the water tank needs to be taken into consideration. You’ll also want to look at extras like timers and programs. Finally, make sure you see what type of maintenance and cleaning is required to keep the unit in good working order and free of bacteria.

Humidifiers have some features you’ll be deciding on. Let’s look at those details first, then we can discuss a few of our top picks from what’s currently on the market.


Cool Or Warm Mist Humidifiers: What’s Best?

A cool mist humidifier doesn’t have to warm water up before emitting it into the air in your home. Such humidifiers work through either evaporative technology or ultrasonic technology. The evaporative cool mist humidifier has a wick inside that draws up the water. Then a fan blows through the wick and causes that absorbed water to evaporate and disperse into your space. An ultrasonic humidifier uses vibration to release cool mist into your space.

Warm mist humidifiers boil the water inside the unit first with a heating element and then emit warm mist into the air. The humidifier’s mist won’t be visible and there is no fan for blowing it into the room.

The evaporative cool mist humidifier and the ultrasonic humidifier don’t usually use as much electricity because they don’t heat anything. They’re also considered to be safer by parents because they don’t have boiling water inside. Their downsides are they can be noisy because of the fan and they can make the room feel colder.

Warm mist humidifiers actually make your air healthier because the boiling of the water first can help to eliminate bacteria and mold present in the water. They’re also usually quieter because they don’t require a fan. They’re not as good for larger spaces, though, and they typically cost more than a cool mist humidifier.


What Are The Features Of The Best Humidifier?

Humidifiers come in all sorts of sizes. If you have a lot of space in the room you’ll be housing yours in, it won’t matter much how large it is. However, many of us are limited on our available space. We won’t want to go with a unit that has a large footprint. Make sure you look at the specs of the humidifiers you’re considering.

The capacity of the humidifier’s water tank could be important to look at as well. If you know you’ll be using your unit every day, you will likely want to go with an option that has a large water tank which doesn’t need to be filled every day.

Whether you choose an evaporative cool mist humidifier, an ultrasonic humidifier, or one of the warm mist humidifiers, there are varying levels of control afforded to you with different models. Some are very basic and offer you a few programmed levels to choose from. Others give you complete and precise control over how much moisture will be released into the air.


All humidifiers will require some level of maintenance. You’ll want to look into just how much you’ll have to be doing to keep your unit running well. If you don’t clean and maintain your humidifier properly, you could be allowing harmful bacteria, mold, and germs into the air that you and your family are breathing inside your home.

A cool mist humidifier uses a fan to disperse the moisture into the air. That means this type can be noisier than an ultrasonic humidifier or warm mist humidifiers. Please consider the humidifier’s noise level you’re best comfortable with before deciding.

Best Safety Humidifiers

The safety features included with different models are important, too. You definitely want a unit with an automatic shut off for when the water tank is empty. You can prevent over-saturation of your air with a built-in hygrometer. Mold is more likely to grow in over-saturated air. Other safety features include UV lights within the water tanks that can kill bacteria, as well as an integrated nightlight.

Now it’s time to look at our picks for the best humidifiers.
