Your Guide to Humidifiers vs. Vaporizers

If you’ve been exploring ways to alleviate dry air in your home, you may have come across humidifiers and vaporizers. But is a vaporizer the same as a humidifier? And if not, what’s the difference between a vaporizer and a humidifier?

While a vaporizer is a type of humidifier, there are important distinctions between it and other types. Namely, vaporizers boil water to create vapor, slightly elevating a room’s temperature. 

Let’s dig deeper into key vaporizer vs. humidifier differences for clarity on which type will be best for you.

What Is a Humidifier?

A humidifier is a device that expels moisture into the air to increase its relative humidity (RH). The type of humidifier you choose will determine how moisture is released from the device.

There are three types of humidifiers: ultrasonic humidifiers, evaporative humidifiers, and steam vaporizers. 

Ultrasonic Humidifiers

An ultrasonic humidifier works by vibrating a metal diaphragm at a sonic speed, which creates water droplets that are then fanned into the room¹. 

Evaporative Humidifiers

An evaporative humidifier draws air into the device from the surrounding area. The air then passes through a moistened wick, which binds water droplets with air molecules, and is fanned back into the room². 

Several Canopy devices fall into this category. providing mist-free hydration throughout your space. The Canopy Bedside Humidifier 2.0 and Nursery Humidifier 2.0 are designed for rooms up to 500 square feet, while our Large Room Humidifier can boost hydration in spaces up to 1,000 square feet. The updated Bedside and Nursery humidifiers also feature optional sleep lights and white noise for further comfort. 

All three models feature Smart Persistent Airflow (SPA)™, which uses sensors to monitor moisture levels inside the device to keep the fan running until it's dry. 

We also offer simplified hydration on the go with our Portable Humidifier. With a cool, ultra-fine mist, it’s ideal for tackling dry air in spaces like hotel rooms and offices. 

What Is a Steam Vaporizer?

While still technically considered a humidifier, steam vaporizers operate quite differently from ultrasonic and evaporative humidifiers. A steam vaporizer, sometimes called a warm-mist humidifier, works by boiling water to create water vapor, which is then fanned into the room¹.

Because water must be heated to high temperatures to turn into vapor, the steam immediately released from a vaporizer can be very hot, as can any water condensation from the device tank. The steam from a vaporizer does cool to a comfortable level when it reaches the room, but experts still advise against using steam vaporizers in homes with babies, small children, or pets. To avoid burning hazards, the American Academy of Pediatrics (AAP) recommends using cool or cold mist humidifiers in nurseries and other spaces where small children are present³.

Humidifier vs. Vaporizer: Similarities & Differences

Whether you use an ultrasonic humidifier, evaporative humidifier, or steam vaporizer, any of these devices will increase indoor humidity levels. But not all humidifiers are created equally, and their differences can have a meaningful impact. 

Here are a few noteworthy differences between ultrasonic and evaporative humidifiers, as well as steam vaporizers. 

Warm vs. Cool Mist

Both ultrasonic and evaporative humidifiers are considered cool mist humidifiers. This means that the moisture they release is below the average temperature. 

Vaporizers, on the other hand, are considered a warm mist humidifier, since the moisture they release is slightly warmer. This often limits their use to the winter months, since they can noticeably warm up a room⁴.

Mold & Bacteria

Because boiling water is an effective way to kill potential bacteria, it makes sense that vaporizers can kill bacteria, mold, and other contaminants when the water is heated to form steam. Cool mist humidifiers can develop bacteria if not emptied and wiped down after each use and disinfected weekly*.  

Recognizing this critical need to keep contaminants at bay, Canopy has taken ample precautions to kill bacteria in all stages of the humidifying process:

• Our no-mist devices provide clean moisture that passes through MERV 5 pre-filters and UV lights 
• Our portable device combines misting with an evaporative fan for clean hydration, as well as proprietary mold-inhibiting SPA technology**
• All parts that touch water are dishwasher safe

This means you can use tap water in your Canopy humidifier and enjoy balanced hydration in your favorite spaces.

Personal Care Benefits 

All humidifiers offer compelling wellness and comfort benefits for you and your loved ones. These advantages range from reducing respiratory discomfort from allergies to combating dry skin.

Here are some noteworthy benefits of regular humidifier use:

• Rehydrate dry, dull skin
• Hydrate dry, cracked lips
• Improve the appearance of fine lines and wrinkles
• Alleviate congestion
• Ease irritation from a dry, itchy throat
• Improve symptoms of the common cold
• Reduce the survival rate of airborne viruses
• Control congestion and improve breathing in babies
• Improve dry, itchy, and flaky scalps¹

In a consumer perception study, Canopy humidifier users reported improvements in skin hydration and appearance—including lip condition—and less nasal passage dryness after 30 days.
