Best Vocal Humidifier – Top 2021 Picks

Growing up with asthma attacks and seasonal allergies in the winters, I knew the struggle that lower humidity levels can cause. For me, dry air also brought about a dry throat, which meant a raspy voice and strained vocals.  This is when a vocal humidifier can really help, especially for singers and musicians. 

If this sounds familiar, then you’ve come to the right place. Whether you’re a singer or just don’t want to live with dry vocals, improving the air quality in your home can help. I noticed this when I started using a humidifier.

This article will help you find the best vocal humidifier as I review the top 5 vocal humidifiers on the market and share a buying guide for the features you should consider.

What is a Vocal Humidifier and How Does it Work?

If you live somewhere with dry conditions, the lack of humidity in the atmosphere inside your house can cause the air to draw moisture from alternate sources to increase the level of humidity.

As a result, dry air can force the moisture to evaporate from our skin and mucous membranes that line our respiratory system – which includes vocal cords.

This can lead to various issues including dry skin, dry throat, coughing, irritated eyes, cracked lips or skin, as well as triggering or worsening the symptoms of allergies and asthma.

This is where air humidifiers can help. These devices are designed to dispense water vapor or mist, consequently increasing the level of humidity or moisture in the air.

In other words,  humidifiers provide dry air with an alternate source of moisture instead of drawing moisture from your skin, lungs, or nose. In turn, this helps prevent problems caused by dry air (along with the administration of medication if necessary).

How Can a Humidifier Help Your Vocal cords?

As I explained above, it’s very likely that your mucosal membranes will dry out if the air surrounding you is dry. This means translates into a dry throat with dry vocal cords, which can make it hard to talk or sing.

Generally speaking, the more humid the air, the more moisturized your nasal passages and vocal cords will be. You want to aim for humidity levels of 40% to 60% as they allow for optimal moisture.

This can help your vocal cords handle the extensive load of singing in dry conditions. If you’ve ever tried singing in a room with dry air, you know how straining it can be.

By providing mist, a humidifier can prevent sore throat and sooth irritated vocal cords.

How to Choose the Best Vocal Humidifier

When shopping for the best vocal humidifier, there are a few features you should consider so you can make the most out of your purchase.

Cool vs Warm Mist

Humidifiers can either dispense cool mist or warm mist. Both options are equally effective when it comes to vocal cords, so it ultimately depends on the temperature of your room.

If your room is cold, you may be better off with a warm mist humidifier, and of course the other way around.

Filter vs Filterless

There two most common types of humidifiers are ultrasonic and evaporative. Ultrasonic humidifiers are quieter, but evaporative humidifiers can be better for singers in some cases.

This is because many ultrasonic humidifiers are filterless, so they can’t prevent minerals from getting dispersed with the mist. These minerals can irritate your throat.

Capacity and Runtime

The runtime of a humidifier varies according to its water tank capacity. The larger the tank, the longer the runtime and the fewer refill trips you need to make.

Remember, a higher capacity doesn’t necessarily mean you should get a humidifier with a bigger footprint. Some humidifiers have a compact design but their tanks are rather large.

So, make sure to check the water holding capacity specified in the description of the humidifier you plan to buy.


A timer allows you to control how long the humidifier stays running. After the set period, the machine will automatically shut off.

This makes the unit more energy-efficient because it’ll stop working when you don’t need it to. A timer also comes in handy when you’re all comfy in bed and suddenly remember that you have to turn off or refill the device.

Automatic Shut-Off

This is a crucial safety feature to prevent the overheating of the humidifier, which protects the unit from getting damaged and protects kids or pets from accidental burns. Humidifiers with automatic shut-off feature will stop working when unable to detect water in the tank.

Noise Level

Finally, consider the noise level when deciding the type of humidifier you should buy. If you’re a light sleeper or you simply don’t appreciate loudness during the day, you’ll definitely want a humidifier with a low noise output.

Ultrasonic humidifiers are very quiet, so they’re a great choice in such cases.
