The Opti-Myst® Aura 3STEP turns water into mesmerizing flame and drifting “smoke,” delivering a flameless, cool-touch experience that looks startlingly real. At 28 inches, this linear design slots into modern feature walls and custom cabinetry without the demands of gas lines or venting, making it a practical showpiece for homes, lobbies, and hospitality spaces.

Because the effect is created from ultrasonic water-vapor, there’s no combustion, no emissions, and no hot glass—just clean, safe ambience you can run anytime. Adjustable lighting and media create depth and glow, while the sealed system keeps day-to-day use simple with routine refills and basic upkeep.

If you’re designing for a statement wall or a multi-unit layout, Opti-Myst Aura offers the realism designers want with the flexibility installers appreciate—bringing a premium look to spaces where traditional fireplaces aren’t feasible.

Optimyst® Flame Effect — Patented Dimplex technology uses water vapor and light to create the world’s most realistic 3D flames and smoke.
Clean & Sustainable — Runs on water and electricity with zero emissions, providing a safe and environmentally conscious alternative to gas or wood fireplaces.
Customizable Flame Display — Adjustable flame height, brightness, and color options (on select models) let you tailor the look to your space and mood.
Adaptable Design — Choose from a variety of configurations—front, left, right, bay, or modular cassette setups—to fit both modern and traditional interiors.
Continuous or Easy-Fill Water Supply — Operate via plumbed connection or easy-access refill drawer, ensuring simple maintenance and long run times.
Crackling Sound Effects — Optional audio adds the soothing, natural ambience of a real wood fire.
Modular Integration — Multiple cassettes can be linked to achieve custom lengths and dramatic linear installations impossible with gas fireplaces.
Flame Connect App Compatibility — Control flame color, brightness, and sound through the Dimplex Flame Connect App or included remote.
Heat-Free Ambience — Designed primarily for stunning visual impact, creating the atmosphere of fire without added heat.
Energy Efficient — Uses low-energy LED lighting and water mist for a low-cost, eco-friendly operation.
