Can You Use a Diffuser as a Humidifier?

Ever wonder if you could use a diffuser as a humidifier?

Today, you’ll learn about the similarities and differences between a diffuser and humidifier. We’ll also explain how you can get both benefits in one so you can save and get the most out of your purchase. 

Diffuser vs Humidifier – What’s the Difference?

The only thing that diffusers and humidifiers have in common is that they add moisture to the air. However, here are some key differences:


  • are typically smaller devices with less water
  • are specifically designed to carry essential oils into the air
  • are usually easy to clean


  • are typically larger devices with more water
  • are specifically designed to create moisture
  • are usually not designed to have essential oils

Can I Use a Diffuser Instead of a Humidifier?

Unless you’re using a diffuser/humidifier combo like the Tower XL, the answer is mostly no. 

Why? Because most diffusers don’t put enough moisture into the air to be effective alternatives. 

Because of how diffusers work, only a small stream of moisture gets released into the air. 

If you live in an area where you need additional moisture, but also want to enjoy the therapeutic benefits of essential oils, try the 2 in 1 combo to get the best of both worlds. 

Can I Use Essential Oils in My Humidifier?

We don’t recommend adding essential oils to a regular humidifier because:

1. Essential Oils are Strong

Since essential oils are highly concentrated extracts, using them in your humidifier is a risk.

The quality of plastic within most humidifiers is not designed to handle the strength of essential oils. 

2. Humidifiers Function Differently

Most humidifiers function by pulling water from the bottom and dispersing it at the top. 

Oil and water don’t mix, so a regular humidifier will not disperse your essential oils properly. 

Is There Such a Thing as a Humidifier/Diffuser Combo?


Thought you’d never ask! Yes, there is. It’s the Tower XL. 

The Tower XL is the world’s first open-top humidifier and essential oil aromatherapy diffuser. The Tower XL has a 2-liter water capacity, which is 20x the size of an average diffuser (100 ml).

It is built with state-of-the-art, medical-grade white plastic to ensure no corrosion occurs. The unique patent-pending air funnel ensures smooth bubble mist flow, which results in a mist volume that is up to 10x the average diffuser.

Fill it, shut it, and forget it. Due to its large tank size, the Tower XL can keep diffusing all night long filling your entire space with a moist aroma. This means you can get a peaceful night’s sleep without having to wake up every couple of hours to refill the tank.


In essence, humidifiers are not designed to diffuse and diffusers are not designed to humidify. However, typical diffusers can help add a minimal amount of moisture into the air. Ultimately, your best bet for both humidity and aromatherapy is the Tower XL, which combines the technologies of both in one.
