The Bilt Hamber air con bomb CITRUS provides a fast and effective way to sanitise and deodorise vehicle interiors. Air-conditioning systems draw external air into cars and, despite the presence of filters, it's not unusual for spores and other organic contaminants find their way into the maze of pipes and ducts that supply treated air to the passenger compartment. Due to the rapid cooling that occurs when the air-conditioning is employed, condensation often forms on the internal surfaces of the air distribution system, and this provides an ideal breeding ground for the growth of bacteria, fungi and mould. This often produces unpleasant odours when the air-conditioning system is used. The Bilt Hamber air con bomb CITRUS combats such odours by killing such organisms with a citrus-scented biocide and depositing molecules that effectively neutralise odours at their source. The air-conditioning system and the vehicle interior are thus left sanitised and protected against odour formation for up to six months.
