What are the hazards of not replacing the air conditioning filter?

The hazards of not replacing the air conditioning filter include the following: 1. During engine operation, impurities such as dust and metal shavings will continuously mix into the cylinders. 2. In hazy weather, there is more moisture and pollutant particles in the air. After being inhaled, they tend to accumulate and solidify, which can cause poor air exchange in the engine and, over time, increase fuel consumption. 3. When haze enters the air conditioning system, moisture and dust will remain on the filter, making it very easy for bacteria to breed. 4. After turning on the air conditioning, it will not only affect the air intake but also contaminate the fan and ducts, leading to a series of problems.
As a parent who often drives to pick up my children, I find it very dangerous not to change the cabin air filter. Dust and pollen accumulate on the filter and get blown into the car when the AC is on, which can easily cause children to sneeze, have allergies, or even cough. It gets worse during pollen season. Prolonged exposure can worsen children's breathing problems and may even trigger asthma. When there's a heavy musty smell, getting into the car on rainy days often feels stuffy and dizzy. A mechanic once told me that a dirty filter can breed bacteria and spread germs. I recommend changing it every six months—health is priceless, so don't neglect it over small savings. From daily use, timely replacement also maintains AC efficiency and normal airflow, making the drive more comfortable. It's a win-win situation.
As a car enthusiast, not changing the air conditioning filter for too long can cause serious harm. The filtration efficiency drops, airflow gets blocked, cooling becomes slower in summer, fuel consumption increases, and prolonged use may lead to fan noise. Worse, dust entering the pipes can corrode the evaporator. A clogged system results in expensive repairs. I once delayed it, causing the system to freeze and nearly damaging the compressor, costing me extra money. Checking and replacing the filter during maintenance is simple and costs just a few bucks—small money to prevent big problems. Especially after driving on dusty roads, timely replacement extends the AC's lifespan and ensures worry-free driving. Don’t overlook these details—car health means driver health.
