Flame simulating assembly including an air filter

A flame simulating assembly having:

• a housing including:
• a top panel;
• at least two side panels supporting the top panel;
• a back panel connecting said at least two side panels;
• at least one front panel positioned substantially opposite to the back panel;
• a simulated fuel bed disposed in the housing;
• a screen positioned behind the simulated fuel bed, the screen having a front surface disposed adjacent to the simulated fuel bed;
• a flame image subassembly for providing images of flames on the front surface of the screen;
• the screen, the housing and the simulated fuel bed delimiting an internal chamber;
• a fan positioned to generate an air flow through the internal chamber from at least one intake aperture, through which air is drawn into the internal chamber, to at least one exit aperture, through which said air in the air flow exits the internal chamber;
• the internal chamber being substantially airtight, except for said at least one intake aperture and said at least one exit aperture;
• and
• at least one air filter for filtering at least a portion of said air in the air flow, said at least one air filter being positioned to filter said air in the air flow.
