Compare the Best Essential Oil Diffusers

Updated on November 19, 2017

Essential oils have been used throughout history for their medicinal and therapeutic benefits.

It has been my experience that the best way to get the full benefits of Essential Oils, is to use an essential oil diffuser. An essential oil diffuser helps break down the molecules in the essential oils and disperse them into the air.

Diffusing essential oils makes them easier to absorb, by breathing them into your lungs, your whole body benefits from their therapeutic properties. Diffused oils can kill bacteria and viruses, take away stress, and increase your feelings of well-being.

I personally have found diffusing essential oils in my home is of great benefit to mine and my families health. My daughter and I both have a touch of asthma, that is elevated during cold and flu season. The diffused essential oils kill the bacteria in our home and keep us healthier throughout the winter months. I have found my allergies that are brought on during the spring are also lessened with the use of my essential oil diffuser.

Another benefit of diffusing essential oils is the amazing fragrance, which I find very beneficial to my stress level. I feel much more relaxed when diffusing certain oils in my home, which in turn benefits my health.

Diffusers that don't use heat are best because exposing essential oils to heat can damage them and decrease the benefits you will receive from them.

This article compares some of the top rated Essential Oil Diffusers on the market. I have highlighted the best functions of each diffuser. I have also included a summary of customer reviews for each system, pro's and con's.

I hope this Review was helpful

There are many different Essential Oil Diffusers to choose from. Your choice will depend on how much you want to spend and how large of an area you are trying to cover. If you just want to diffuse while your sleeping, you will not need as powerful of a unit. But if you are trying to keep a larger area free from viruses and other bacteria, you will want a larger unit or more than one.

Good Luck finding the right Essential Oil Diffuser for your needs.

Be sure to read the directions for the diffuser that you select. Make sure that the essential oil you want to diffuse can be used in the unit that you purchase. Some Oil Diffusers don't recommend using citrus oils in them, as it will corrode the unit.

Always make sure that you are using 100% Pure Therapeutic Grade Essential Oils.
