It's recommended to replace your cabin air filter every 12,000 to 15,000 miles, especially if you live in a densely populated area or a large city. Doing so can improve engine performance and the efficiency of your car's heating and cooling system. If you don't replace a dirty or clogged filter, you may experience a decrease in air volume, bad odors in the cabin, or premature failure of HVAC components. Replacing the air filter can make a huge difference in the air quality of your car.
The oil filter is also important for supplying clean oil to the engine. Changing the cabin air filter will significantly improve the air quality inside your vehicle. Even though it doesn't directly affect how your car moves from point A to point B, it's still important to buy a new one and replace it regularly. If you suffer from allergies, you may want to consider changing the filter more often to reduce your symptoms.
You can find mileage marks for recommended cabin air filter changes in your car's owner's manual, although they vary by vehicle type and manufacturer. The best way to ensure that the air is clean is to change the cabin air filter as often as recommended by the car manufacturer. When the engine is blocked, it means that the vehicle does not receive enough clean air in the cylinder, causing a rich mixture. Additionally, when you don't replace a dirty cabin air filter, condensation can form on the windshield.
The cabin air filter prevents dust, dirt, pollen, bacteria and exhaust fumes from entering your car's HVAC system. It also keeps the air inside the car fresh so that you and your passengers can breathe easy. When air passes over the cabin air filter, debris is trapped by the filter instead of being pumped into the vehicle. You'll be surprised to see a filter covered in soot, dirt, leaves, twigs, and other dirt, confirming that replacement service is important.
This affects the cabin air temperature which depends on a constant flow of air passing through the heater core or evaporator. Rich White, Executive Director of the Car Care Council emphasizes how important it is to replace your cabin air filter. He says: “Checking the cabin air filter is a simple preventive maintenance step that goes a long way in protecting passengers, as well as the vehicle's HVAC system.”.
