A gas purification apparatus has a housing with an inlet end having an inlet port for gas supply to an interior chamber, and an opposite, outlet end having an outlet port for exit of purified gas from the chamber. The housing is of generally cylindrical shape with a central axis, and the inlet and outlet ports are offset from the central axis towards a lower portion of the housing. A purification medium fills at least the majority of the chamber. The internal wall of the chamber is cylindrical along part of the length of the housing extending from the outlet end, and has a rounded or part-spherical inlet portion extending from the inlet port to the cylindrical part of the internal wall.
