How often should the air conditioning filter of Volkswagen Santana be replaced?

The air conditioning filter of Volkswagen Santana should be replaced every 30,000 kilometers, and the replacement cycle can be adjusted appropriately according to actual driving conditions. Here are some introductions about the air conditioning filter: 1. When the car is driving with the air conditioning on, it needs to draw in external air into the cabin, but the air contains many different particles, such as dust, pollen, soot, grinding particles, ozone, odors, nitrogen oxides, sulfur dioxide, carbon dioxide, benzene, etc. 2. Without the air conditioning filter, once these particles enter the cabin, they not only pollute the car's air conditioning and reduce the performance of the cooling system, but also cause allergic reactions, lung damage, irritability due to ozone stimulation, and the influence of odors when inhaled by the human body, all of which affect driving safety.
As a Volkswagen Santana owner who commutes daily, I've noticed that changing the air conditioning filter directly affects in-cabin air comfort. The manufacturer's manual recommends replacement every 12-24 months or inspection at 15,000-20,000 km intervals. However, given the heavy dust and exhaust in urban driving, filters clog easily, so I typically replace mine annually. Unchanged filters accumulate dust, pollen, and even bacteria, resulting in musty airflow and breathing discomfort. Once when I delayed replacement, the AC airflow weakened noticeably, and heating performance dropped. Now I either have mechanics check during maintenance or buy parts online myself - spending just dozens of RMB. Post-replacement, the cabin air becomes refreshingly cool, driving mood improves, and it helps prolong the AC system's lifespan.
