The Designer Fragrances Air Con Refresh Bomb is a single-use aerosol fogger designed to clear unpleasant odours out of a car's air conditioning system rather than just masking them in the cabin. Once activated, the 150ml CFC-free can works through the vehicle's air conditioning system and is stated to refresh the interior in around five minutes, making it a quick fix before a valet, a long journey or simply when the cabin has picked up a musty smell. It comes in four fragrances, Black Code, Azul, Fleur and Cherry, each inspired by a market-leading perfume or aftershave, so buyers can match the scent to their own taste. It pairs well with a general car interior valet or a hanging air freshener for everyday upkeep between treatments.
