The Best Essential Oil Diffusers 2021 (Guaranteed Satisfaction)

When you are looking to make a purchase you obviously want to make sure you get one the best essential oil diffusers possible. So where do you start?

As you know there are literally hundreds, thousands even, on the market. The answer will be different for everyone because it all depends on what you wish to use it for!

You need to consider the running time per day, the size of the space you want to fill with aroma and the method of diffusion.

Do you want fine mist, cool mist, or continuous mist? Do you want evaporative diffusers, nebulizer diffusers or ultrasonic?

We can help you with all of those choices!

The first consideration, in my opinion, is that you need to eliminate any that are heat diffusers, those that utilize a heat source for essential oil dispersion.

When a diffuser uses heat with essential oils it can destroy the healing properties.

This will mean eliminating a huge number of potential diffusers. However if you have are investing your money you want to make sure that you don’t destroy the quality of your essential oils and you are able to harness their healing properties.

Heat has a negative impact on most essential oils. In fact the health giving and healing properties of essential oils are destroyed when heated. You will end up with beautiful aromas, but no holistic healing or aromatherapy benefits.

Note: If your prime motivation is aromatherapy and ambiance only, and you are not using your oils for healing – then by all means…heat away!).

The Best Essential Oil Diffusers Do Not Use Heat!

Even after removing products that use a heat source, there are a huge variety to choose from.

By far the best are Ultrasonic diffusers. Ultrasonic means they vaporize the essential oils and disperse them into the air through vibration.

Because ultrasonic diffusers generate vapor without heat, actually without anything other than high speed vibration, they preserve the integrity and attributes of our essential oils.

So here they are! We have tested and trialled many diffusers and think we have narrowed it down to the 5 best!

Perfect solutions for diffusing essential oils with ultrasonic technology. No heat! With these you will achieve the maximum benefits of Aromatherapy.
