An air treatment device (2) including a housing (3) having an enclosed fan (4), wherein the housing is arranged for releasable receiving inlet filter means connected to a suction side (8) of the fan and outlet filter means connected to a pressure side (13) of the fan. The housing (3) includes first connecting means including on the one hand elements for cooperation with a pre-filter in the form of at least a first particle filter (5), on the other hand elements for cooperation with at least one tubular first carbon filter (6',6"), for the coupling thereof with its inside to the suctions side of the fan and in a flow direction downstream of the pre-filter. The housing (3) further includes second coupling means including on the one hand elements for the cooperation with at least one tubular second carbon filter (9',9") for coupling thereof with its inside to the pressure side of the fan, on the other hand elements for the cooperation with an after filter (10) in the form of at least one second particle filter such that it, seen in the flow direction, is downstream of the said second carbon filter. The invention also concerns a system and a method for air treatment. |
