How to Remove Odor from Car Air Conditioning?

[StMadelyn]

Here are the methods to remove odor from car air conditioning: 1. Replace the cabin air filter during maintenance: The cabin air filter needs to be cleaned and replaced regularly. After prolonged use, especially in dusty and polluted urban environments, the filter can become clogged with dust. At this point, no amount of cleaning will restore its air filtration capability, and the accumulated dust and dirt may circulate into the car cabin with the air, causing more severe pollution. 2. Open doors and sunroof to air out in sunlight: For mild interior odors, you can park the car under direct sunlight on a sunny day. Set the air conditioning system to warm air mode, turn the fan to maximum speed, and leave all doors and windows open for about ten minutes. This serves two purposes: first, ultraviolet rays can help disinfect the interior; second, the warm air facilitates complete circulation of stale air in the ventilation ducts. The advantage is that this method costs nothing, but it can only eliminate relatively weak odors. 3. Clean ventilation ducts: Bacteria in the ducts can also cause air conditioning odors. A simple solution is to use an air conditioning duct cleaner to eliminate unpleasant smells from the ventilation system.
