    • The invention relates to an air purification device which comprises a filter tank (18) at the bottom of the housing of the device, which is partially filled with a deodorizing solution (19) for an air purification cycle. During the air purification cycle the solution loses its effectiveness so that it is cyclically renewed without pressure from a reservoir (43) at the top of the housing. The filter tank (18) is a closed wet-type filter system and comprises a wet-type filter device that is impinged upon by a radial fan (25) with the air to be purified. Said filter device is formed by a plurality of knitted hoses (29) as the filter elements which consist of a material that is permeable to the deodorizing solution and which are arranged, closely spaced apart, in a plurality of successive rows in front of the air outlet opening on the back of the filter tank (18), a center vertical twisting element subdividing the knitted hoses in two sections. A circulating pump conveys the deodorant solution from the filter tank (18) to a level above the knitted hoses (29) from where it trickles down on the knitted hoses onto which the air is blown .
