If the car air conditioning filter is not replaced regularly, it will cause multiple negative impacts. First, a clogged filter will lead to a significant drop in filtration efficiency, increasing the PM2.5 concentration inside the car to more than three times the normal level, which may induce respiratory diseases or exacerbate allergic symptoms, particularly posing greater risks to children and pregnant women. Prolonged operation under these conditions may shorten the compressor's lifespan by up to 40% and result in additional annual fuel consumption of 80-120 litres (equivalent to approximately 600-900 ringgit in extra costs). Mechanically, accumulated dust combined with condensation can corrode circuit boards, with 28% of air conditioning control module failures attributed to this issue. Economically, delayed replacement may increase subsequent maintenance costs by 5-8 times while reducing used car resale value by 3%-5%. Replacement intervals should be adjusted according to usage conditions: urban commuter vehicles require changes every 15,000 km or 6 months; high-pollution areas necessitate 3-month intervals; long-distance vehicles should undergo professional inspection every 20,000 km. Optimal protection requires HEPA-grade filters (99.97% filtration efficiency) with standardized activated carbon content (80-120g/m²).
