Opti-myst® Cassette

Opti-myst® Cassette

Revolutionary ultrasonic technology is used to create the flame and smoke effect of the Dimplex® Opti-myst®. As the mist rises up through the curved plate, the light reflects against the water molecules creating a convincing illusion of flames and smoke. The result is an appearance so authentic it will be mistaken for a true wood-burning fire.
