Warm Mist Humidifier vs Vaporizer

Two peas in a pod. Six of one half dozen of the other. Looks like a duck, quacks like a duck, must be a duck…
These are all phrases that remind me of a Warm Mist Humidifier vs Vaporizer compared.

What is the difference between a warm mist humidifier and a vaporizer?

A warm mist humidifier is essentially the same product as a vaporizer.
Only a Vaporizer typically comes with a chest rub additive to disseminate a soothing vapor into the air.

Both the warm mist humidifier and a vaporizer use the method of boiling water to create steam.

And steam happens to be a warm mist…
A cool mist humidifier on the other hand does not create steam like a warm mist humidifier or vaporizer.

It is a system of basically dispersing a cloud of fine water droplets into the air that are cool or at least room temperature.

Cool Mist Humidifier vs Warm Mist Humidifier

Cool mist humidifiers according to Mayo clinic offer more relief for congestion and cold symptoms than warm mist humidifiers.


Warm mist humidifier and vaporizer are two appliances that do the same thing. As humidity to the air through the creation of steam. A cool mist humidifier adds humidity to the air by dispersing cool humidity droplets into the air.

difference between Warm Mist Humidifier vs VaporizerWhat is a waterless vaporizer?

Imagine if you combined Vicks vapor rub with a Glade plug-in air freshener,
That’s essentially what a waterless vaporizer is.

If you are looking for a way to disperse Vicks vapor rub into the air without adding humidity through the air,
Waterless vaporizers or an excellent product.

And because most parents do not want to have a machine that is boiling water in their children’s room, waterless vaporizer are an excellent way to help your little ones breathe easier at night.

Warning: Waterless vaporizers may not be safe for infants under 6 months old because they can be too strong and irritate their airways.

Waterless vaporizers can also combined with a cool mist humidifier with no issues.

What’s the difference between a waterless vaporizer and a diffuser?

Both a waterless vaporizer and a diffuser disperse vapors into the air that can be beneficial and help with breathing.

But the difference in price is somewhat significant.

A waterless vaporizer is a convenient plug in that can be refilled easily for a small price. $12.

On the flip side

Although the diffuser itself is usually inexpensive, it does require essential oils to add in order do you have something to disperse.

That’s where the real price is.

Some essential oils that are known to be good for colds and breathing like peppermint can run in the $30 range.
Frankincense, another essential oil known for being very beneficial but can run in the $70 range just for the one oil.

Diffuser vs. HumidifierDiffuser vs. Humidifier

Do you get the feeling we’re going around in circles?

Humidifiers and diffusers can share in a few functions but they are made for two different things.

The humidifier is made to add humidity to the air and that is its primary function.

A diffuser is made to disperse essential oils into the air and that is its central purpose.

Where they have commonalities is that they are both made to help you breathe easier.

And there are certain humidifiers that come with a tray to add essential oils making it essentially a essential oil diffuser / humidifier. Essentially…

But though you can purchase a humidifier that can double as a diffuser, not all diffusers can return the favor.

Ultrasonic diffuser vs nebulizer

Diffusers come in two different types.
Ultrasonic and nebulizer.

Ultrasonic diffusers have a water basin that you fill with water and add your aromatherapy oils into.

And just like a cool mist humidifier, it mist the air with tiny droplets of water.
The difference is the water is combined with the scents.

A ultrasonic diffuser can be used as a humidifier simply by leaving the oils out of the water.


A nebulizer diffuser does not use water and since the oils are not diluted in water, the nebulizer diffuser is much stronger.

The takeaway is that if you’re wanting to combine the moisture of a humidifier with the therapeutic and medicinal effects of a diffuser,

The only choice is the ultrasonic diffuser.

What’s the Best choice?

The Ultrasonic diffuser combines all the functions of a humidifier, a waterless vaporizer, and a essential oil diffuser.

Of course, individually these appliances may have their strengths when bought separately, an ultrasonic diffuser who’s the best combination device to get the best out of all worlds.

Do you want us to take it a step further?

There is a device called a “Revitalizer”

A revitalizer is a combination humidifier, essential oil diffuser, and air purifier.

Imagine a humidifier that pulls air into a basin, slushes the water around to clean the air, then releases the air combined with essential oil aroma.

That’s what a Revitalizer is and does.

Still with me?

How about an “Air washer”?

Air washers are air purifiers that can clean the air up to about 250 square feet by using water as a filter.

Air washers are also available with essential oils and double as humidifiers.

But the caveat here is that both revitalizer is and air washers supply their own essential oils that are formulated to not gum up any working parts on the machines.

Sum it up

So many machines that are so similar.

Vaporizers, warm mist humidifiers, ultrasonic diffusers, waterless vaporizers, revitalizer, and air washers
all share most of the same functions.

They all add humidity to the air and they all diffuse aromas into the air.

And with the revitalizer and air washer, you also have a air purifier to boot.

As you can imagine, these machines all have their strengths when used individually.

For instance, a vaporizer uses boiling water to create steam. That makes it a much cleaner machine and offers the benefits of steam to help with congestion.

Ultrasonic diffuser vs nebulizer

A nebulizer diffuser as an individual product is a much stronger aromatherapy diffuser then a ultrasonic diffuser that is combined with other functions.

And a air washer is primarily a air purifier that can double as a humidifier with essential oil additives.

But as a combination product I would choose a ultrasonic diffuser because it offers a good balance between humidifier and diffuser.

And I would leave the air purification to other technologies that are much better at improving air quality than revitalizers.
