Details

It measures 7.1 by 7.1 by 8.9 in (18 by 18 by 22.5 cm). Mist output adjusts from 100 to 300 ml per hour. It draws 25 W. Rated noise is under 36 dB, for rooms of about 330 to 430 sq ft (31 to 40 m²). It stops when the water runs out. The Classic styles have one knob. The Pro styles add a display, timer and humidity buttons and a remote. Both come in white or black.

A small plate vibrates very fast and breaks the water into a fine, cool mist, with nothing heated. The mist leaves through the top and carries any added oil with it.

How to use

Fill the tank with clean water and add a few drops of essential oil. Plug it in and turn the knob or press power. On the Pro styles, set the mist and timer by button or remote.

Shipping and returns

Ships in 24 to 48 hours, then 6 to 9 business days in transit. Free shipping over $75. 30 days to return an unused item in its original packaging.

Safety

Use it indoors only. Unplug it before filling, moving or cleaning. Empty and dry the tank after use. Keep it and your essential oils away from children and pets, keep oil off the skin, and never swallow it.

Questions

Four things people ask

Does an ultrasonic diffuser use heat?

No, nothing is heated. A small plate vibrates fast enough to turn water and a few drops of oil into a cool mist, so the scent leaves without heat and the piece stays cool.

Which oils can I use in it?

Any of the twenty House of Dusk oils. They come in 10 ml bottles of essential oil, and you can see every one in the oil collection. Water goes in first, then the oil, and the mist carries the scent out.

How much is it, and is shipping free?

This one is $119.90, and shipping is free over $75. Below that shipping is a flat $5.90, and an unused piece in its original packaging can go back within 30 days.

How do I clean an ultrasonic diffuser?

Switch it off, empty the tank, wipe it dry with a soft cloth, and let it air before the next fill. Standing water is what dulls a diffuser over time, so empty it after each use.
