NOVELTY - The utility model claims a cleaner, comprising a unit main body, the unit main body is provided with a fan and a filter core, the filter core is composed of a primary filter net, depa high efficiency filter and active carbon plate; the active carbon plate is filled with active carbon particles and nanometre mineral crystal, the active carbon purifying plate is attached with a graphene layer, a photocatalyst layer and formaldehyde decomposing enzyme layer. The utility model can realize the normal air filtering effect, and the filter element is attached to can decompose pollutant functional graphene, photocatalyst layer and formaldehyde decomposing enzyme layer can be attached on the filter core of the impurity decomposition, prevent large impurity deposited on the filter element, so as to prolong the service life of the filter core and reduces the operation cost of the equipment.
