A fluid conduit disinfector includes a conduit with a fluid disinfection channel defined by inner side surface of the conduit, wherein the inner side surface of the conduit is reflective with a germicidal ultraviolet (GUV) light reflectance R of 50%-99%; a GUV light source for emitting GUV light into the fluid disinfection channel; a fan for forcing a fluid to be disinfected to flow through the fluid disinfection channel, and a filter for filtering particles from the fluid. The fluid disinfection channel may include a first section, a second section and a third section, wherein the first section has a cylindrical shape with a first diameter, the third section has a cylindrical shape with a third diameter larger than the first diameter, the second section has a truncated conical shape and is positioned between the first section and the third section.
