Not many essential oil diffusers boast the good looks of a vase, but the Ellia Blossom diffuser could easily pass as an objet d’art with its simple ceramic pottery and wood design. Easily the most elegant diffuser on our list, this Ellia model is as functional as it is pretty. Perfect for a bedroom or hallway.

Some essential oil diffusers take centre stage in a room, but not the Muji diffuser: this one is unobtrusive and characteristically minimalist – the best of Japanese design. Designed with small homes in mind, this will sit perfectly on a small bedside table or desk, and will complement most decorating styles. The ambient glow this diffuser produces is so pretty that you will want to use it as a reading light even when you're not using it as a diffuser. Most essential oils diffusers double up as humidifiers, but the Muji produces more of a cool, dry mist, which is great if you don't want to add too much extra humidity to your room. Whilst it's not the quietest model on our list, the sound it does make is rather pleasant – like a very small water feature.
Where to buy essential oils
You can either buy essential oils along with your essential oil diffuser, or separately. Some devices are only recommended for use with the brand's fragrances, for example, Neom diffusers. Otherwise, you can buy essential oils anywhere, from Amazon to your local supermarket. If you're a first-timer, then we suggest buying an entire set so that you have a few scents to switch between as the seasons change, and to help you decide what you like. We own and love the PHATOIL Essential Oils Set from Amazon (opens in new tab) – these are therapeutic grade and budget-friendly. Shop more essential oils below.
What to consider when buying 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.
This will all depend on where your new essential oil diffuser will live, but be sure to measure the one you're eyeing up to ensure it's the right size for you. There are compact options for bedside tables and smaller rooms such as hallways, or larger essential oil diffusers for bigger spaces. Usually, the larger the device, the bigger the water tank – and the longer it can continuously or intermittently fragrance your home. If you're looking for something to hide away behind a book, choose a compact option – there are lots out there.
Consider the number of hours the machine will work for before turning off, whether continuously or intermittently switched on. This is important as if this number is low, you'll need to keep refilling the water tank, which can be annoying – especially if you use your diffuser at night whilst relaxing.
Last but not least, you might want to bear in mind the material of the reed diffuser you want to buy, for aesthetic reasons. Whether it's plastic, wood or ceramic is down to you. Several of our plastic options are BPA free too.
