Description

Some rooms only need a little. This compact 300ml ultrasonic diffuser sends up a fine cool mist that softens dry air in a small bedroom, a reading nook or the corner of a desk, carrying whatever essential oil you like along with it. It is sized for the space it sits in rather than trying to scent a whole floor, which is exactly why it works so well on a nightstand or beside a monitor.

Operation comes down to a single push button, so there is nothing to configure at the end of a long day. Press once for mist, press again to cycle the light, and leave it to run. The slim cylindrical body is finished in black or white with a small footprint, and the ultrasonic mechanism produces cool mist quietly, with no heating element and no fan noise competing with music, a film or your own thoughts.

A 7-color LED glows through the top for a soft, low light that works as a gentle night light or a bit of desk atmosphere after dark. Fill with clean water and a few drops of pure oil, empty and rinse the tank regularly so the mist stays clean, and keep the unit and any oil bottles on a stable surface out of reach of children and pets with the caps closed between refills.

  • Compact 300ml tank sized for small rooms and desks

  • Quiet ultrasonic cool mist with no heating element
  • 7-color LED glowing through the top as a soft night light
  • Slim cylindrical body in black or white

Frequently Asked Questions

What size room does it suit?

Small to medium spaces such as a bedroom, a home office corner or a reading nook. For an open plan floor a larger machine works better.

How long does a tank run?

300ml lasts several hours on a continuous setting and considerably longer on an intermittent mode, which is plenty for an evening or a working session.

Is it quiet?

Yes. Ultrasonic diffusers use vibration rather than a fan, so there is no motor noise to distract you while working or falling asleep.

How much oil do I add?

A few drops per full tank is enough. Adding more does not make the scent noticeably stronger and uses up your oil faster.

How do I clean it?

Empty and wipe the tank weekly so old oil does not build up. That keeps the mist strong and stops one scent lingering into the next.
