Whatever your taste - ultra modern, traditional or classic, Dimplex has a fire to suit your decor and lifestyle. Opti-myst fires require water to be added and minimal regular cleaning. The magic of an Opti-myst fire Theres nothing quite like the effect of a fire. It creates a wonderful feeling of comfort and cosiness. Looking deceptively real, an Opti-myst fire will capitivate you from the moment you see it. The fully 3-dimensional effect creates authentic looking flames and smoke delivering a warm and cosy atmosphere to any room. with its Revolutionary technology The flame and smoke effect is created using ultrasonic waves which atomise water to create an extremely fine mist. This is not steam since the water is at room temperature and, therefore, the flames are safe to touch. As the mist is so fine it does not add significantly to the humidity of the room. Dimplex has fine-tuned the ultrasonic transducer to produce the most realistic flame and smoke effect possible. Anti-microbial additives For added peace of mind, an anti-microbial substance has been added into the plastic material used in Opti-myst fires. Also, a report by the Microbiology Department, University College Cork concluded that the unit offers no risks to use from a microbiological perspective. Easy to clean It is recommended to use filtered water in Opti-myst fires. If tap water is used, a build up of limescale can seriously hinder the production of flame and smoke effect. However, if a build up of limescale does occur, the plastic materials used have a highly polished finish to ensure easier cleaning and removal of limescale. The sump can even be placed in a dishwasher.
