A new cabin air filter can not only improve the air quality inside your vehicle, but it will also significantly enhance the airflow of your vehicle's heating and air conditioning system. Dirty or excessively clogged cabin air filters can produce a dusty and damp odor, especially when the HVAC system is turned on. Replacing the cabin air filter at regular intervals will ensure that passengers don't have to roll down windows in the middle of winter to get fresh air. Failing to replace a dirty or clogged filter will affect the efficiency of your car's heating and cooling system, leading to a decrease in air volume, bad odors in the cabin, or premature failure of HVAC components.
Simply replacing a dirty filter can make a big difference to your car's air quality. The cabin air filter is usually located behind the glove compartment and cleans the air as it moves through the vehicle's HVAC system. If you notice that your car has an unpleasant odor or that airflow has decreased, consider replacing the cabin filter to give the system and yourself a breath of fresh air. Be careful not to break any of the clips or pins that hold it when accessing it. The engine air filter ensures that clean air reaches the engine, while the cabin air filter ensures that clean air arrives in the cabin.
Most manufacturers recommend changing the cabin air filter every 12,000 to 30,000 miles, depending on the vehicle and where you are driving. If your car isn't equipped with a cabin air filter, you can add an ion purifier. If the cabin air filter is full of harmful debris, this usually means that the air conditioner will work harder when expelling hot or cold air. Most late-model vehicles contain cabin air filters to trap material in the air that can make traveling in a car less pleasant. A cabin air filter placed beyond its useful life will cause a vehicle's HVAC system to work harder, which can cause the engine to burn out.
This affects the cabin air temperature, which depends on a constant flow of air passing through the heater core, evaporator, or both components. When you replace your cabin air filter, you'll immediately notice a difference in the driving comfort and efficiency of your defrost, heating and cooling systems. A cabin air filter prevents contaminants such as dirt, dust, smoke, smog, pollen, mold spores and exhaust gases from entering the cabin of a vehicle through its HVAC system. Just because a cabin air filter doesn't directly affect your vehicle moving from point A to point B doesn't mean you should delay buying a new one or not replacing it at all. Changing the cabin air filter is an important part of regular vehicle maintenance, and ignoring it can cause some rather uncomfortable effects.
