10 Unbeatable Essential Oil Diffusers

Aroma, you may agree, makes life all the more beautiful. And is there anything as strong in aroma as essential oil? Honestly, none. You see, the oil is extracted from its natural source and packed at its most concentrated, hence the strong, appealing smell.

To get the aroma to fill your appointed space, you will need a diffuser. These ten make it to the top of our list for their inherent capabilities to disperse essential oil. What we loved about these diffusers is that most of the double up as humidifiers.


You may have heard people talking about improvised methods of diffusion such as tissue paper, steam, and candle diffusion. While these natural methods are cheap, they do not disperse the aroma far enough, and it certainly does not last as long as it does when you use professional diffusers.

Tao Tronics Essential Oil Diffuser

First, this aromatherapy essential oil diffuser is beautifully crafted with a faux wooden base and lighted plastic top. The wood part is a light brown, still grainy for an artsy look. It is made with hard plastic that has been coined to look like hardwood.

It has a broad base, stable enough to hold and keep it on any surface. Its two small legs help stabilize it further. It is new to the market, but it has been received with overwhelming responses from eager customers who have probably tried other diffusers from Tao Tronics.

The Material

Esthetics aside, this diffuser is made to meet the industry standards, with the plastic being BPA free, so it is 100% safe for you and your family because there are no harmful emissions. It is particularly important that you look out for this factor when you are allergic or have asthmatic concerns.
