The cabin air filter helps clean the cabin air as it enters the vehicle through the HVAC system. The filter cleans the air of dust, pollen, smoke and other pollutants before it enters your car.

The cabin air filter, found on many late model vehicles, is most often located around the glove box area, including directly behind the glove box, with filter access either through or by removing the glove box. Some other areas for a cabin air filter include the back of the outside air intake, above the fan, or between the fan and the HVAC case. If you're not sure, have a mechanic check where the cabin air filter is in your car before replacing it.

When to change the cabin filter

Knowing when to change the filter can create a difficult situation. You don't want to change it too early and waste money, but you also don't want to wait for the filter to stop working. The guidelines say you should replace the cabin air filter in your car every 12,000-15,000 miles, sometimes longer. Consult your owner's manual for the manufacturer's maintenance schedule and when to replace your vehicle's air filter.

An important factor in determining the best time to change the filter depends on how often you drive, the quality of the air you drive in, and whether you drive in heavy traffic or not. The longer a car's air filter is used, the less it filters out all the dust, pollen, and other external pollutants because it clogs with use. Eventually, the air filter becomes more and more ineffective, preventing air from flowing into the ventilation system. At this point, you should have it checked by a mechanic to see if it needs to be replaced.

Signs you need to replace your cabin air filter

While driving, there are certain signs to be aware of when the cabin air filter needs to be replaced by a mechanic. Some common signs that the cabin air filter needs replacing include:

• Reduced air supply to the HVAC system due to clogged filter media.
• Increased fan noise as it works harder to bring fresh air through a dirty filter.
• Bad smell when turning on the air in the car

The best time to check the cabin filter

The best time to check the condition of the cabin air filter and determine if it needs to be replaced is before winter sets in. The reason for this is because your car has been hard at work cleaning the air that enters your car in the spring, summer. , and fall. At this time of year, the filter saw the worst pollen. By changing it now, you can prepare for next year's warm weather. When changing the filter in your car, ask your mechanic what cabin air filter is best for your car.
