How to Deal with Unpleasant Odors in Car Air Conditioning?
2 Answers
Unpleasant odors inside the car can be masked and absorbed using the fragrance of fruits. This method is relatively straightforward for eliminating odors in the car. Activated charcoal has excellent adsorption properties and can absorb various gaseous, colloidal, and particulate pollutants in the air. An air purifier is a highly effective way to remove odors.
I know all too well about the issue of unpleasant odors in car air conditioning systems—I've seen it countless times over my years as an auto technician. The most common culprit is a dirty and moldy cabin air filter. You can easily replace it yourself by opening the glove compartment to locate the filter—a new one costs just 10-20 yuan. If the smell persists after replacement, bacteria may have built up on the evaporator, requiring professional cleaning. You can either visit a repair shop or purchase a cleaning spray to disinfect the air intake vents. A crucial preventive measure is turning off the A/C a few minutes before parking while keeping the fan at maximum speed to dry out moisture, which helps prevent mold growth. Don't neglect regular maintenance, or the odor will keep coming back and may even affect in-cabin air quality. Prevention is key: replace the filter at least twice a year and avoid cluttering your car with unnecessary items.
