The device is for disinfecting and filtering intake air 4 in a vehicle ventilation system and is ideally joined between connection pipes/hoses (18,18’, figure 7) of the ventilation system using flanges 28,28’ of the device and clamping rings 26,26’. The device comprises: a housing 10 having an inlet 16 and outlet 8; a fan 12 to draw air through the device; and a high-efficiency particulate air (HEPA) filter 20 surrounding an ultraviolet radiation lamp 14 so that intake air admitted by the inlet is sifted and sterilized to provide purified air 6 before leaving the housing by the outlet. The filter may be cylindrical and comprise pleats arranged such that an angle (Ɵ, figure 3B) between adjacent pleats is 30 degrees or less, e.g. 8 degrees. Ideally the housing comprises first and second end plates 30,30’, and a bottom plate 24 is provided at an end of the filter distal the inlet to define an inner space 22 within the filter and an air gap (33, figure 1) between the bottom plate and second end plate. Fixation members (66,68, figures 5A-C) may be used to mount the device to a wall (62, figures 5A-c) of the ventilation system.
