The Ember Diffuser uses an advanced ultrasonic vortex to create a realistic flame-like mist effect. There is no actual fire, no heat, and no combustion. It's completely safe to use around children and pets. The "flame" is cool mist — you can pass your hand right through it.

Any water-soluble essential oil works beautifully. We recommend pure, high-quality oils for the best scent throw. Avoid thick carrier oils or synthetic fragrances — they can clog the ultrasonic plate. Every order ships with two essential oil samples (Lavender Calm and Citrus Uplift) so you can start using it the moment it arrives.

The 300ml reservoir provides 6–10 hours of continuous misting depending on the mode selected. The low-mist mode extends runtime while the high-mist mode creates a more dramatic flame effect.

Yes. Operating at under 26 dB, the Ember Diffuser is quieter than a whisper. You'll see the flame dance but won't hear a thing — perfect for bedrooms, meditation spaces, or offices where silence matters.

Simply empty the tank, wipe the interior with a soft cloth, and use a cotton swab to gently clean the ultrasonic plate once a week. No disassembly required. The entire process takes under 2 minutes.

Yes — the ultrasonic mist adds light moisture to your space, which can help with dry air. However, with a 300ml tank, it's designed primarily as an aroma diffuser and ambient light rather than a full-room humidifier.

Ember is USB-C powered. Plug it into a laptop, power bank, wall adapter, or any USB-C source. The cable is included — no proprietary chargers or batteries to replace.

Ember is just 6.3" tall and under 1 lb. It's about the size of a coffee mug. It fits comfortably on any nightstand, desk, shelf, or bathroom counter.
