Sometimes it can be VERY confusing! There is a difference between these items, and as I’ve been learning more and more about essential oils over the last year, I am still continuing to advance my knowledge in aromatherapy and therapeutic blending. When first starting out with EO’s, I was confused, about many things! And as I continue to study on my own free time {insert laugh here!} The time is very limited. I would like to share with you the things I learn and have found very useful in our journey to becoming more intentionally natural & healthy in our everyday living.

I look at it this way, we use all kinds of different tools for different things in our kitchens, same goes for humidifiers, vaporizers and diffusers each does it’s own thing.

Here is my version of the differences.  Hopefully a helpful reference for you.
Humidifiers vaporize water into the air. Increasing the amount of moisture in any one area.  The ultimate purpose of a humidifier:  To increase humidity by heating water and oils. Using oils with a humidifier can often “break apart” the full nutrients you receive from essential oils due to access heat. Giving you less than a 100% effect.
Warning: Make sure your humidifier is actually made for the use of essential
oils. Some
EO’s can eat away at some plastics, and therefore ruin your machine. Be sure your machine is EO friendly.


Vaporizers – boil water, releasing moisture and steam into the air.  Any liquid including that of essential oils when added to them will change into a vapor or a gas and
be released into the air as a steam. The ultimate purpose of a vaporizer: Is to increase moisture and is used for individual inhaling treatment purposes by heating water and oils.

Make sure you are using a vaporizer that is actually made for the of use essential oils.  Some EO’s can eat away at some plastics, and therefore ruin your machine. Be sure your machine is EO friendly. If your vaporizer is not made for EO’s you can also loose the effectiveness of your oil.


Diffusers –  are made up of many forms, shapes & sizes and  and are used almost solely for the purpose of diffusing EO’s for all types of aromatherapy purposes. This includes, but are not limited to: electric diffusers, ceramic diffusers, lamp rings, etc. Most Electric EO diffusers are designed to vaporize a micro fine mist, dispersing a cold air misting effect, scattering and spreading water molecules combined with EO’s. These very fine water droplets give the EO’s a ride in the air so to speak. Electric diffusers do not create heat to create “steam” to dispense oils. Ultimate Purpose of a Diffuser: Is to disperse essential oils into a large area to create a therapeutic effect on respiratory systems, and aromatic effect in any room.

I personally love my electric diffusers, and use them almost on a daily basis, along with my oil burner and wall burners for a more healthy aromatic home.

Looking forward to sharing more with you!
