Best Essential Oil Diffusers in the UK

Essential oil diffusers not only make your home smell nicer, they can also make you feel more relaxed too. Essential oil diffusers are a more natural, healthy and eco-friendly alternative to artificial air fresheners, and they’re a good option if you react badly to artificial chemicals.

Diffusers are good at removing musty smells and the smell of smoke that you might encounter when you move into a new property. They’re also good at preventing your home from acquiring an unpleasant smell that you might not even notice.

Most of the diffusers reviewed here produce a cool mist which can help reduce congestion and relieve cold and flu symptoms—an added bonus. Many diffusers also feature a lamp, so they can be used as a nightlight.

We’ve reviewed five of the best essential oil diffusers you can buy in the UK in 2017. See our top three in the table below, or scroll down for more in-depth reviews. We hope this helps you choose the right diffuser for you!
