The unit comprises a glass reactor with a gas inlet, and a purified gas outlet, a light source, and supports coated with a catalyst, which are positioned relative to the light source and gas flow so they can oxidize 90% of a model impurity comprising acetone moving at a speed of at least 300 micro-moles of the model impurity per hour, per watt of power of the light source and per square meter of support surface illuminated by the source. The unit comprises a glass reactor (1) with an inlet for the gas, e.g. air, to be purified and an outlet for the purified gas, a source (4) of UV or visible light radiation, and one or more supports (3) coated with a catalyst capable of at least partial oxidation of impurities contained in the gas. The supports are positioned relative to the light source and gas flow so they can oxidize, in the presence of a catalyst, 90% of a model impurity comprising acetone moving at a speed of at least 300 micro-moles of the model impurity per hour, per watt of power of the light source and per square meter of support surface illuminated by the source. The support can be in the form of flat rings positioned to create a turbulence in the gas flow to promote the movement of the impurities to be oxidized towards the catalyst. An Independent claim is included for a gas purification procedure using the above unit.
