How often should the car air conditioning filter be replaced during maintenance?

[LaOscar]

Car air conditioning filters should be replaced every 10,000 kilometers. Below is relevant information about car air conditioning filters: 1. Function: Ensures clean air in the cabin without breeding bacteria, creating a healthy environment. Effectively separates solid impurities such as dust, core powder, and grinding particles from the air. Effectively intercepts pollen, ensuring that drivers and passengers do not experience allergic reactions that could affect driving safety. 2. Cleaning method: If the filter is dirty, clean it by blowing compressed air from the opposite side. Hold the air gun 5cm away from the filter and blow at 500kPa pressure for about 2 minutes. The air conditioning filter easily accumulates dust; simply blowing away the loose dust with compressed air is sufficient.

As an ordinary person who drives frequently, I believe the replacement frequency of cabin air filters should be determined flexibly rather than following a rigid rule. For example, when I mostly do short urban drives with good road conditions and relatively clean air, I typically replace it every 10,000 km or 6 months, basically following the maintenance manual's recommendation. A dirty filter affects air freshness - you'll notice weaker airflow and unpleasant odors from the AC, which impacts both mood and health. After periods of high summer temperatures or frequent rain when filters are prone to mold growth, I always inspect or replace them in advance. I order filters online for just tens of yuan and can replace them in two minutes by opening the glove compartment - it saves both time and money. Delaying filter replacement reduces AC cooling efficiency and increases fuel consumption, which ends up being more costly. Generally, adjust the interval based on your driving habits and environment - rural areas with cleaner air can have longer intervals, while heavily polluted cities require more frequent changes.

I have sensitive respiratory issues, so I place great importance on replacing the air conditioning filter, insisting on checking and renewing it every 8,000 kilometers or 8 months. The filter traps dust, pollen, and bacteria, and when used for too long, the air quality inside the car deteriorates, causing family members to cough and sneeze while driving. In harsh environments like industrial areas, I even replace it every 5 months to minimize the inhalation of pollutants. Not replacing the filter also affects the performance of the air conditioning, increasing the burden on the fan and, in the long run, slightly raising fuel consumption. DIY replacement is simple, and spending a little money to prevent bigger issues is worthwhile. I recommend developing a habit of regular checks—clean cabin air makes for a more pleasant drive, and investing in health is the most important choice.
