Can You Put Essential Oils to a Humidifier?

There is only one type of humidifier to which you can add essential oils, and that is the so-called 2-in-1 device. For other devices, I strongly advise against this due to the following reasons:

  1. The machinery and parts of the humidifiers are made of plastic material. Therefore, concentrated liquids like essential oils destroy this device by eating away the plastic components.
  2. The essential oils will clog the wet-wicking system’s filters in the cool-mist humidifiers, causing device breakdown
  3. The heat produced by the warm mist humidifier will change the oil’s nature, altering its scent profile and effectiveness.

I’ll also tell you about 13 types of essential oils that will both help you relax and boost your mood. Fasten your seatbelts, there’s a lot more to come!

Humidifiers vs Diffusers

Although humidifiers and diffusers share various matching components and operate similarly, they mainly differ in their functioning and what they add to the air. Humidifiers increase humidity levels in your room by converting water into moisture.

On the other hand, diffusers don’t make moisture, but they add fragrance to your room by dispersing essential oils. Conventional humidifiers aren’t designed to diffuse these oils. Unlike some humidifiers though with dual functionality, the diffusers are only designed to disperse essential oils.

Types Of Humidifiers: Are All of Them Suitable for Atomizing Essential Oils?

As I mentioned above, there are different types of humidifiers, and not all of them are equally suitable for adding essential oils to them. If you don’t want to ruin your appliance, then check out the 4 main types of humidifiers and see if you can put essential oils into them or not. Let’s get started!

Evaporative Humidifiers

1. Evaporative Humidifiers

The evaporative humidifiers are suited for expansive rooms and are energy efficient, but not for dispersing essential oils. These devices work by blowing air through a wet-wicking filter using a fan, causing water droplets to evaporate and humidify in the air.

2. Warm Mist Humidifiers

These humidifiers are a must-have for people with respiratory congestion but they cannot disperse essential oils. These devices release fresh and clean air by heating water and cooling the steam before releasing it.

3. Cool Mist Humidifiers

Cool mist humidifiers increase moisture levels by producing a cool mist without increasing the room temperature. This device is recommended for homes with pets and kids, and diffuse essential oils.

4. Ultrasonic Humidifiers

Ultrasonic humidifiers turn water into a fine mist using ultrasonic vibrations. Some types of these humidifiers are available as 2-in-1 devices and can be used as both a humidifier and an essential oil diffuser at the same time.

However, adding essential oils to a container of water is still not allowed. These models have a special compartment for adding essential oils.

Important! To avoid spoiling the device, read the operating instructions before adding essential oils and make sure it is safe to do so.

What To Consider When Diffusing Essential Oils With Humidifiers

So, can you put essential oils in a humidifier? The answer is yes, but remember, diffusing oils in a humidifier incorrectly never ends well. Based on my experience, I share vital points to consider before you put essential oils into the water reservoir of your humidifier:

  1. Investing in high-quality oils: Although they are cheaper, low-quality oils produced by unknown brands will quickly damage your humidifier. So, opt for the costly, pure, and therapeutic-grade oils from renowned brands to reduce adverse reactions and damage to the humidifier.
  2. Selecting a Compatible humidifier: Using the right equipment will guarantee better results and minimize losses. I advise using a nebulizing or ultrasonic humidifier to diffuse essential oils.
  3. Frequent and Thorough Cleaning: Develop the habit of cleaning your humidifier immediately after use. This culture will hinder the build up of residue and promote air quality.
  4. Diluting Essential Oils: Mixing the oil with water before adding it to the humidifier’s tank is helpful. The water effectively hinders the oil from contacting the components of the humidifier directly. This will greatly minimize the risk of damage.
“Putting essential oils in a humidifier will spread a pleasant aroma in your room. To stop potential damage, always follow the manufacturer’s instructions.” Robert Tisserand, Essential Oil Educator
