An air purifier comprising a housing 1, 2, the housing having a plurality of air inlets 5 and a plurality of air outlets 3, an ultraviolet radiation tube means 21 located within said housing between said air inlets and air outlets for generating ultraviolet rays, at least one extractor fan means 8 drawing air into said housing through said air inlet, over the ultraviolet radiation means and out of the housing through the air outlet. An air collector 27 is provided between said extractor fan and said housing. A high negative voltage discharge/carbon fibre 10 is located between the ultraviolet radiation tube and the air outlet to produce and increase the quantity of anions. The purifier may be provided with protection means to prevent extreme ultraviolet radiation being emitted from the housing to protect the eyes of the user. The system may emit ultraviolet radiation at a wavelength of 253.7nm. The UV tube may be replaceable and the system may be placed in an air-conditioning device. Also claimed is an air purifier comprising inlets and outlets, a filter (6, 7), an ultraviolet radioactive ray chamber for housing an ultraviolet radiation means, a carbon fibre for regenerating anions, the housing including a rectangular hole-site which fastens an external power line, the air purifier further comprising a switch to turn the power on or off. |
