Which is better for essential oils, a humidifier or a diffuser?

Can you put essential oils in a humidifier?

This is a common question that comes across our minds because both the devices seem to be sending out steam or water vapor and have a water tank. However, you must remember that they are two separate devices. Humidifiers work differently from oil diffusers.


The two types of humidifiers are cool mist humidifiers and warm mist humidifiers. While cool mist humidifiers use a fan that helps the water vapors dissipate into the indoor air, a warm mist humidifier heats the water from the water tank and the water evaporates into vapor droplets.


A cool mist humidifier and a warm mist humidifier by themselves are two separate devices. Adding essential oils to the water tank directly can lead to clogging or oil buildup in the tank. They can even lead to forming of mineral residues in the water vapor. Most humidifiers that support aromatherapy have a separate compartment to add essential oils to them. This separate compartment will not interfere with the performance of the humidifier to add moisture and it will also prevent oil buildup.


An essential oil diffuser on the other hand is a device specially designed for essential oil use with a unit to add essential oils. Its mechanism will have water vapor filled with the vaporized oil. Its design for essential oil use will atomize oils and gently sprays the vapor across the single room it is placed in. Nebulizing diffusers are ideal for their therapeutic function.


In what types of humidifiers should essential oils never be used?

Most humidifiers made these have provision to add essential oils in them. A cool mist humidifier is a better option for aromatherapy. Just like how an ultrasonic diffuser vibrates, an ultrasonic humidifier will vibrate with sound vibrations to convert water into water vapor. This will retain the properties as taken from the original plant.

In what types of humidifiers should essential oils never be used?

A warm mist humidifier is not recommended for the use of essential oils because a warm mist humidifier will heat the water to a boiling point that will diminish the properties of the oils taken from the original plant. If the warm mist humidifier has a compartment to add moisture and essential oils to them, you can go in for a combo model of this kind.

What is the best way to use a humidifier with essential oils?

The best way to use a humidifier with essential oil is to place it in a central position in the home. If a whole home humidifier model has a tray to add in an essential oil of your choice you can invest in that model.

How to choose the right essential oil for humidifier?

Choosing the right essential oils for your cool mist humidifier or warm mist humidifier (if the model is designed for it) is simple. Select an oil that can be used without a carrier oil, an oil that will fulfill your requirement (to promote sleep, and relaxation, or to help with cold symptoms), or an oil that is readily available.
