What is the best essential oil diffuser?

We think the best essential oil diffuser you can buy is the Ellia Aspire Ultrasonic Essential Oil Diffuser. However, we are aware that it's not within everyone's price range. So if you're after something cheap yet most definitely still cheerful, opt for the VicTsing Aroma Diffuser

How to buy the best essential oil diffuser

A far cry from plug-in air fresheners which can be bulky, plasticky and unsightly, these standalone diffusers are all designed with aesthetics as well as functionality in mind. Curvy shapes and premium materials are the order of the day, no matter where you’re planning on putting your diffuser, although if you’re thinking of using your diffuser every night, consider one like the Esteban Timer Edition Ultrasonic Electric Diffuser, which doubles up as a clock to really earn its place at the bedside.


We've listed the dimensions of each product, so that if you're after something to hide away behind a book, you can picture its size.

We've also noted the amount of hours the machine will work for before turning off; our longest are the first two picks at 10 hours.


Last but not least, we've listed the material of the reed diffuser whether it's plastic, wood or ceramic. Several of our plastic options are BPA free too.

You can set the timer so that the diffuser releases a mist upon waking – try a zingy citrus oil like grapefruit that’ll really make you want to spring out of bed – as well as beginning to glow for a more gentle start to your morning than the average alarm.
