They’re the new scented candle.

From the coolest boutiques to the best spas and salons, everyone’s misting the air with a non-stop flow of essential oils.

While the oils are nothing new (the last time they were trendy we were burning them in little candle-lit dishes, remember?), the 2018 obsession is with diffusers, handy little gadgets that introduce your favourite oils into the air in vapour form.

You can choose an oil for every situation or feeling. Pop in some lemon oil when you need to concentrate on that proposal or end-of-year report. Add some lavender to relax before bedtime or some eucalyptus or peppermint to refresh your senses in the morning.

Geranium oil is the great balancer, while clary sage, jasmine, neroli, patchouli and rose are known as aphrodisiacs.

Bergamot, frankincense, geranium and mandarin are also helpful in dealing with anxiety… plus they make your house smell amazing.

There’s even an oil to help you attract more money into your wallet; patchouli is associated with abundance and prosperity, while cedarwood is said to help purge negative energy from people and places.

Here are five of the most popular oil diffusers on the market:
