About this item

  • The flame is the mist. Ultrasonic vibration lifts water into a cool plume, an LED lights it from underneath, and the draught makes it move — which is why it flickers like fire instead of sitting there like a fog machine.
  • Two separately controlled lights: the flame plume and the ember bed behind the glass. Both change colour from the remote, so it can be an orange fire or a blue one.
  • Infrared remote: power, 1 / 3 / 5 hour timer, flame colour, fireplace colour.
  • 150 ml tank. Add a few drops of essential oil to the water if you want the scent; it works perfectly well as a plain humidifier without.
  • Waterless cut-out. When the tank runs dry the unit shuts itself down rather than running the ultrasonic plate against nothing.
  • 261 x 101 x 97 mm and about 378 g — long and low, made to sit on a shelf, a mantel or the end of a desk.
  • Powered by 5 V / 2 A over a USB-A to USB-C cable, supplied. The mains plug is not — use any 5 V phone charger you already own.

Product description

This flame diffuser humidifier is a miniature fireplace on a shelf: cool ultrasonic mist lit from below rises like fire over a glowing ember bed, with a remote for colour and timer. The mist it produces is lit from below and rises like a flame, an ember bed glows behind the glass front, and an infrared remote sets a 1, 3 or 5 hour timer and changes the colour of both. It runs on 5 V over USB-C and holds enough water for an evening.

Flame diffuser humidifier — A fire you can put on a bookshelf

A fire you can put on a bookshelf

There is no heat, no flame and nothing to burn — the fire is lit water vapour. That means it can go somewhere a real flame or even a candle cannot: a bookshelf, a bedside table, a rented flat, a room with a cat in it. What you get is the movement and the colour of a fire, at the scale of a paperback.

Flame diffuser humidifier — Set it and forget it

Set it and forget it

The remote runs a 1, 3 or 5 hour timer, so it can be started at the beginning of an evening and left. When the water runs out the waterless cut-out stops it anyway. Between the two, the failure mode of forgetting about it is that it turns itself off.

Flame diffuser humidifier — Scent optional

Scent optional

The tank takes 150 ml of plain water and a few drops of oil if you want it. Without oil it is a small humidifier with a fire in it. That is worth knowing if you live with a cat or a dog — see the safety note, because several common essential oils are toxic to animals and the honest answer is to run it with water only.

Safety information

Essential oils and pets. Many common essential oils are toxic to cats, dogs and birds. If there is an animal in the house, run this on plain water, or diffuse only in a room the animal cannot enter and ventilate it afterwards. Stop immediately and call a vet if an animal drools, vomits, wobbles or struggles to breathe. Keep the unit and any undiluted oils out of reach of children. Unplug before filling or cleaning, do not immerse the base, and empty the tank if it will not be used for a while.

Customer reviews

  • The flame is better in person

    Photographs make it look like a screen effect. It is lit mist and you can tell the difference immediately in a dark room.

  • Replaced candles in a house with a toddler

    Same feeling in the room, nothing burning, nothing hot to touch.
    Ademola Fayemi
    Verified purchase

  • Ember bed sells the illusion

    The printed logs behind the glass are what makes it read as a fireplace rather than as a mist box.

  • Black one against a white wall

    Looks like a piece of furniture rather than an appliance. Bought the black and would again.

  • Independent colour for flame and embers

    Warm orange fire over a deep red bed. Very few units at this price let you set them separately.

  • Quiet enough for a bedroom

    Faint water sound, no fan, no buzz.

  • Works on plain water

    We run it scent-free because of the cat. Still worth having for the flame alone.

  • Remote means it goes on without getting up

    Sofa, dark room, one button. That is how it gets used every night.

    I wipe the disc every couple of weeks as instructed and it has not weakened.

  • Best at eye level or below

    On a high shelf you lose the ember bed. On a coffee table it is perfect.

Frequently asked questions

How big is the fireplace diffuser?

261 x 101 x 97 mm and about 378 g, long and low for a shelf, mantel or desk end.

Does it switch off when the water runs out?

Yes. A waterless cut-out shuts it down when the 150 ml tank empties.

Is it actually hot? Can it burn anything?

No. There is no heating element and no flame. The plume is cool water mist lit by an LED, so it is cool to the touch and there is nothing to catch fire. It still contains water and electronics, so treat it like any other small appliance.

How quiet is it?

Not silent, whatever the source page says. The supplier's own noise chart marks the running level at 50-60 dB, which is roughly quiet conversation. Most people stop noticing it; light sleepers should not put it on the bedside table.

How long does a tank last?

The supplier does not publish it, so neither will we. The tank is 150 ml and the timer tops out at 5 hours, which suggests an evening rather than overnight. The supplier does not publish a run time.

Do I have to use essential oils?

No. It works as a plain humidifier and flame lamp on water alone, which is what we would suggest in a home with a cat or a dog — see the safety note.

Is it safe around pets?

Only on plain water. Diffusing essential oils around cats in particular is a real risk: cats lack an enzyme needed to process many of them, and tea tree, eucalyptus, citrus, pine, peppermint, cinnamon and ylang-ylang are all on veterinary caution lists. Birds are more sensitive again. If there is an animal in the house, run it with water only, or keep it in a room the animal cannot get into and ventilate afterwards.

Does it come with a plug?

No — it comes with a USB-A to USB-C cable. Any 5 V phone charger rated 2 A or better will run it, as will a laptop or a USB power bank.

Can I change the flame colour?

Yes, from the remote, and the ember bed behind the glass is on a separate button, so the plume and the logs can be different colours.

Does the water need to be anything special?

Tap water is fine in a soft-water area. If your kettle furs up, use filtered or distilled water — the same limescale will otherwise settle on the ultrasonic plate and the output will drop off.

How long does shipping take?

Every order ships within 2–3 business days (Monday to Friday, excluding Chinese public holidays) and is then delivered in 6–10 business days in most countries and 8–15 in Canada and Mexico — so most parcels arrive 8–13 business days after you order. Express delivery (4–5 business days) is available at checkout, and the tracking link is emailed as soon as your parcel ships.

Is shipping free?

Yes, on every order of $29 or more. Below that, standard shipping is a flat $9.99, shown at checkout before you pay.

What is your return policy?

You have 30 days from delivery to return an unopened, unused item in its original, undamaged packaging — no reason needed. Email us your order number first and we reply with the return address; return postage is paid by you and shipping charges are not refunded. If an item arrives damaged, faulty or wrong, contact us and we take it back at our cost. The refund goes out within 3 business days of the return reaching us.

Is there a warranty?

Every product carries a full 1-year warranty on top of the 30-day money-back promise.

Which payment methods do you accept?

All major cards, PayPal, Apple Pay and Google Pay — processed through Shopify's encrypted, PCI-compliant checkout.

How do I track my order?

You'll get a tracking link by email as soon as your order ships, and you can check progress any time on our Track Order page.
