The beauty and effectiveness of ultrasonic diffusers

Surrender to some much needed aromatherapy with essential oil infused vapour from an ultrasonic diffuser.
Last Updated on May 16, 2025 by Abhi Weston

Using water, the following elegant devices effortlessly disperse your favourite essential oils into the air via a fine mist, transforming your space into a sanctuary of soothing scents. You may find the scented vapour in the air helps you breathe better and feel less congested.

A good ultrasonic diffuser is ideally made of ceramic or BPA-free plastic. These materials are easy to clean, do not corrode from the oils used, and are durable. It should facilitate excellent scent throw across the room evenly and not just in one place. 

And as it takes up at least 15cm in height, I’d imagine you want it to look good too. Catering to various tastes and needs, the following diffusers promise all this and then some! So, let’s dive in.

 

1

Asakuki premium essential oil diffuser

Brand: Asakuki
Price: £23.99
Size: 500mL tank
Height: 12.1cm

If you have a child that sleeps better with a night light but you want to help them breathe freely during the dreaded cold season, you may like the simple yet effective design of The Asakuki essential oil diffuser.

With healing oils such as eucalyptus or tea tree, this ultrasonic diffuser seamlessly humidifies the dry air and you can feel the difference in your nasal passages immediately. My children go from snorting, phlegmy little creatures to much more pleasant when they sleep with this on!

I confidently keep it on all night to help with their chest congestion so they can enjoy a continuous, restful sleep. Research suggests that an orange or red glow is best for sleep and if you time the fading colours just right (takes a little practise!), you can set it to the exact shade you want. 

Be sure to plug the cable in first and then add the water with a jug, as the hole for the cable is underneath the tank.  Just be aware, if you decide to turn the night light off completely, there is a small flashing green dot that indicates the diffuser is working. 

Ensure you ventilate the room after use.
