Flame Aroma Diffuser · Cool Mist

A Fireplace. Made of Mist.

An aroma diffuser shaped like a hearth: the flame you see is cool ultrasonic mist, lit from below over glowing logs. Add a few drops of essential oil, set the timer from the remote, and let the room settle down with you.

150ml tank, 5+ hours · Whisper-quiet 30dB · Auto-off when dry

See it burn.

A flame of cool mist, a remote, a tank you fill from a glass of water.

The Hiro's Hearth glowing in the dark, cool mist rising from its lit log bed
Recorded on the production unit. Silent by design — nothing to mute.
  • Fill it

    150ml from any glass of water, up to the max line. A few drops of essential oil if you want the room to smell like something.

  • Light it

    One press wakes the flame. Another cycles the log bed and the panel through seven colors, together or apart.

  • Leave it

    Set 1, 3 or 5 hours from the remote. It shuts itself off when the tank runs dry, so you can fall asleep first.

No, it isn't fire.

The flame is ultrasonic mist lit from below by LEDs. You can hold your hand in it.

  • Nothing burnsThere is no flame and no combustion. Safe on a wooden shelf, near curtains, around pets.
  • Nothing heats upThe mist is cool to the touch. The only warmth in the room is the color of the light.
  • It stops on its ownDry protection switches it off when the 150 ml tank empties, so you can fall asleep first.

Two ways to do this.

The Hearth was built around one scent in particular. This is how it was meant to arrive.

Give it something to carry.

The Hearth runs perfectly well on plain water. Add a few drops of oil and the mist carries it instead: the same flame, and a room that smells like you meant it to. Eleven scents, and one of them is the house.

  • Sandalwood

    The house scentThe one the Hearth was designed around, and the one that arrives with it. Warm, dry, woody.

  • Vanilla

    The default eveningWarm and sweet, and the one that matches the amber flame. If you only ever run one, run this.

  • Jasmine

    Deep, late, quietA flower that opens at night. Heavier than it sounds, and better after everyone else has gone to bed.

  • Lavender

    Last one awakeThe quiet one. Set the five-hour timer, fill the tank, and let it empty while you sleep.

  • Lemon

    For the deskBright and clean, for the working hours rather than the evening ones.

  • Green Tea

    Mid-afternoonGrassy and thin in the good way. It makes a closed room feel aired out.

  • Cherry Blossom

    Early springSoft and faintly sweet. Lighter than it sounds, and it does not linger.

  • Lily

    Clean linenWhite flowers without the weight. For rooms that already smell of nothing.

  • Ocean

    Cold fireSalt and cold air over a warm light. Odd, and rather good.

  • Osmanthus

    Apricot at duskSweet stone fruit with something tea-like underneath. The least obvious bottle here.

  • Violet

    After midnightPowdery and old-fashioned, the way a good perfume is old-fashioned.

Nobody has written one yet.

The store is new. We could show you reviews carried over from the supplier's listing — the identical products elsewhere do exactly that — but those describe a factory, not this store.

So instead, the part we can actually promise: thirty days to send it back, no reason required, and we pay the return shipping.

FAQ

How long does shipping take?

Orders are processed in 1 to 3 business days (that covers 90% of them), then shipped tracked. Just over half of parcels arrive 5 to 11 days after dispatch, so plan on roughly 6 to 14 business days door to door. We ship within the United States only for now.

Is the flame hot?

No. The "flame" is cool ultrasonic mist lit by LEDs. You can pass your hand through it. Nothing burns and nothing heats up, so it's fine on a wooden shelf, near curtains, or around pets.

What do I need besides the Hearth?

Two AA batteries for the remote, which are not in the box, and an oil if you want scent. Everything else is included: the diffuser, the remote, a USB-C cable and its wall plug. The simplest answer is The Hearth & Its Scents at $84, which is the Hearth, the four-bottle Starter Set and a bottle of Sandalwood — $114.99 if you bought the three separately. No code; the price is the price. The Hearth on its own is $69.99, and any water-soluble aroma oil works in it.

Which oils can I use?

Any water-soluble aroma oil. Add a few drops straight into the 150ml tank and the mist carries the scent. Ours come in eleven scents, sold as a four-bottle Starter Set or one at a time, and they travel on the same line as the Hearth, so an order with both arrives in one parcel. Skip the oil whenever you just want plain, unscented mist. Tank only: never put these on skin.

What is your return policy?

30-day no-questions-asked returns. Email hirosnoirsupport@gmail.com and we'll handle it.

Can I leave it running overnight?

Yes. Set the 5-hour timer and it runs roughly until the 150ml tank empties, then the dry-protection switches it off on its own. At about 30dB it's quieter than a soft conversation.

All questions, answered

Ready to bring one home?

The flame is mist, the logs just glow, and the room smells like you meant it to. The Hearth & Its Scents is all three — the diffuser, the four-bottle Starter Set and Sandalwood — for $84. No code; the price is the price.
