The invention relates to a filtering media having a photocatalytic action which has a thickness of at least 2 mm, which is homogeneous and which is devoid of orifice apparent to the naked eye, comprising a felt of inorganic fibers, the fibers of which are coated with a coating comprising a catalyst having a photocatalytic action, said felt exhibiting a weight per unit area of between 30 and 80 g/m2, said coating representing 5 to 80% of the weight of said media, said media exhibiting a gas pressure drop of less than 150 Pa at 1 m/s in unpleated condition. This media is intended to be incorporated in a purifier of gas, such as air, furthermore comprising a system for illuminating said media with UV radiation. The media exhibits an excellent purification efficiency and a very low pressure drop.
