Apparatus for the degradation and/or modification of allergenic germs, bacteria, viruses, spores and other substances existing in the air in order to combat some allergies comprises a vertical casing formed by an insulating material suitable to prevent infra-red and ultra-violet rays and heat from propagating. Infra-red lamps are located in the lower part of the casing with an air inlet in the wall of the casing at the level of the infra-red lamps. Ultra-violet lamps are located in the upper part of the casing and an air outlet is provided in the casing wall above the air inlet at an intermediate part of the casing defining an air accumulating chamber inside the casing above the air outlet. The accumulating chamber can be adjusted in size. The air outlet is adjustable downwardly to cause an increase in the accumulating chamber. Also the accumulating chamber can be increased by decreasing the distance between the air outlet and air inlet. Also, the air inlet and air outlet can be provided with adjustable diameters to control the exposure time of the air to be treated by the infra-red and ultra-violet lamps. Two support elements can also be provided to extend over each side of the apparatus to provide a balance-like effect to allow the apparatus to be flexible, thereby to increase or decrease the chamber area.
