Abstract
A fluid purification device is provided, which comprises a chamber having an inlet and an outlet, a fluid mover, such as a fan, which causes fluid to pass through the chamber from the inlet towards the outlet and four elongate UV-C light sources in an arrangement such that fluid passes along their length and such that each light source forms an elongate edge of a square prism. The volume of the chamber and the speed of fluid movement as caused by the fluid mover are such that the fluid has a residence time in the chamber of greater than 1.0 seconds. The device may in particular be used to purify air.
