An air cleaning apparatus 10A for deodorising or cleaning of air containing noxious or toxic odours is disclosed. The apparatus 10A includes a controller that is a PLC 1, an air pump 2, a solenoid 3, a manifold 4, a pressure gauge 5, an air supply line 6 and air supply lines 7 and 8 in fluid communication with the manifold 4. It also includes a first tank 12 that contains a deodorising solution, a second tank 13 contains a detoxifying solution and the third tank 14 contains an oxidising/disinfecting solution. These are the components that are delivered into the air to deodorise and/or clean the air. The apparatus 10A further includes outlet conduits or lines 9, 10 and 17 which are in fluid communication with in line filters 18, 19 and 20 which as shown are in fluid communication with solenoids 21, 22 and 23. The apparatus further includes supply flow conduits 26, 27 and 28 which are in flow communication with an evaporation assembly 29 where a phase change of said decontamination solution occurs to convert it into an activated molecular species.
