Most Humidifiers Are A White Plastic Box
Central heating dries a room out from October, and the usual fix is an appliance you would rather hide behind a plant. The Kratera is a volcano in a crackle glaze on a light wood base, and the mist comes out of the crater.
An amber LED sits inside the crater and lights the column from below, so the base of the plume glows orange and fades to white as it rises. 300 ml, about ten hours at the stated 30 ml an hour, running off USB-C, the same brick as your phone.

Why It’s Better


- 300 ml Tank: At 30 ml an hour that is about ten hours, so one fill covers a working day or a whole night.
- Amber Mist Light: An LED inside the crater lights the column from below, glowing warm orange at the base and fading as it rises.
- Crackle Glaze: A dense web of fine cracks over the cone, so it reads as a ceramic object rather than an appliance.
- USB-C Powered: The same cable and brick as your phone, with no adapter to lose.
- Ultrasonic: A vibrating plate makes cool mist, so nothing is heated and nothing gets hot.
- Quiet Enough For A Desk: 36 to 45 dB, a soft hiss you stop noticing within a minute.
Perfect for a desk in a dry heated room
It is on your desk, so you will end up watching it. That is not a claim about air quality, it is just what happens when something moves and glows in the corner of your eye at four in the afternoon in February. The crackle finish is the other half: it reads as a ceramic object rather than a molded appliance.
Something to look at, and moisture in the air.


Questions

I have a cat. Can I use essential oils in it?
Please check with your vet first. Many common essential oils are toxic to cats, tea tree, eucalyptus, citrus, peppermint, pine and ylang ylang among them, and cats cannot metabolise them the way people do. Birds are more sensitive again. Plain water is completely fine in this unit and is what we would use in a home with a cat or a bird. If you do diffuse anything, do it in a ventilated room the animal can walk out of.
What does it do to the air?
It puts moisture back into it. Dry indoor air is what leaves you with a scratchy throat, a blocked nose and a static shock off the door handle every winter, and this pushes a cool ultrasonic mist back into the room all evening. Add a drop of oil and the same mist carries the scent with it.
How long does a tank last?
A 300 ml tank and a 30 ml per hour output, which works out at roughly ten hours. That is arithmetic from their two figures rather than a tested runtime, and it will vary with the setting and the room.
Is it quiet enough for a bedroom?
Yes, 36 to 45 dB. That is a soft hiss and a faint bubble, the sort of sound that disappears within a minute of lying down. Plenty of people run it all night.
What water should I use?
Filtered or distilled water if your area is hard. Tap water works but mineral scale builds on the plate faster and shortens the time between cleanings.
How do I clean it?
Empty it after use rather than leaving standing water in it, and wipe the plate with a soft cloth every week or so. Standing water in any humidifier is the thing that makes it smell.
Why this rather than a plain humidifier?
Because you will actually leave it out. Amber light rising through the mist and a crackle-glaze volcano finish make it an object on a shelf, and it still does 30 ml an hour for about ten hours.
