A filter assembly for use with an associated candle having an elongated wick which in normal operation is disposed vertically. The apparatus further includes a filter, the filter including means for extracting smoke from the emissions of the associated candle, and a housing. The housing includes means for supporting the filter above the associated candle whereby the filter assembly reduces emissions from the associated candle when the associated candle is burning. In some forms of the filter assembly the housing includes means for directing combustion products from the associated candle to the filter. In other forms of the invention the filter assembly the means for directing surrounds at least the sides of the highest axial extremity of the associated candle. The housing may be dimensioned and configured to extend completely around the highest extremity of the associated candle and in addition continue to a higher elevation to allow support of said filter assembly in spaced relationship to the associated candle. The housing, in some forms of the invention, has a substantially fluid tight wall that directs all gases rising from a flame burning at the wick at the highest axial extremity of the associated candle to the filter assembly.
