AIR PURIFICATION DEVICE WITH REMOVABLE STRUCTURE.

Device for purifying the air in a passenger compartment of a vehicle consisting of a particle filter (40) comprising a layer of non-woven fiber lining, folded in accordion to ensure that undulations appear, characterized by the fact that the device consists of a gas filter (30) comprising a first layer of nonwoven fiber coating, a second air purification layer that covers the first layer and constituted by a photocatalyst agent intimately associated with grains of an adsorbent, and a third coating layer of non-woven fibers that covers the second layer, the set of these three layers being folded in accordion to achieve the appearance of corrugations, the particle filter and the gas filter, in said device, presenting ripples of the same step that overlap exactly, in order to allow a fit of the two filters inside each other to form a structure to common.
