An air decontamination device comprises an air stream generator ( 20 ), a nonthermal plasma filter ( 22 ), an ultraviolet radiation emitting device ( 24 ), an ozone catalysing device ( 26 ), and a hydrocarbon emitter ( 28 ). The air stream generator ( 20 ) generates and directs an air stream through or across the non-thermal plasma filter ( 22 ), the UV radiation emitting device ( 24 ), the ozone catalysing device ( 26 ), and the hydrocarbon emitter ( 28 ). The plasma filter ( 22 ) produces free radicals by which contaminants in the air stream are neutralised. The UV radiation emitting device ( 24 ) beaks down ozone in the air stream, catalysed by the ozone catalysing device ( 26 ). The hydrocarbon emitter ( 28 ) discharges an aromatic hydrocarbon into the air stream to preferentially react with residual ozone so that the air stream becomes suitable for human exposure. A method is also provided.
