<p>An air decontamination device comprises an air stream generator (20), a non ithermalplasma filter (22), an ultraviolet radiation emitting device (24), an ozonecatalysing device (26), and a hydrocarbon emitter (28). The air stream generator(20) generates and directs an air stream through or across the non-thermal plasmafilter (22), the UV radiation emitting device (24), the ozone catalysing device(26), and the hydrocarbon emitter (28). The plasma filter (22) produces freeradicals by which contaminants in the air stream are neutralised. The UV radiationemitting device (24) breaks down ozone in the air stream, catalysed by the ozonecatalysing device (26). The hydrocarbon emitter (28) discharges an aromatichydrocarbon into the air stream to preferentially react with residual ozoneso that the air stream becomes suitable for human exposure. A method is also provided.</p> |
