What Are the Consequences of Not Changing Your Cabin Air Filter?

If you don't change your cabin air filter, the filter will become clogged with dirt and debris, reducing the efficiency of your car's filter and HVAC system. This will lead to a decrease in air volume in the passenger compartment, resulting in bad odors and even mold growth. Inhaling mold can cause serious health issues, so it's important to replace your cabin air filter regularly. The general rule is to change or at least check it every 15,000 to 30,000 miles, depending on the climate and air pollution in your area.

A dirty or clogged cabin air filter will not be able to filter out contaminants, which can be especially problematic for people with allergies or breathing difficulties. Your car's cabin air filters are essential for keeping the air inside your car fresh and free from harmful smells and smoke. However, there is no specific lifespan for a cabin air filter as cars operate at different intensities. You should change it as needed when you notice signs that the system is working harder than usual to push air through the filter and out the vents.

Additionally, if you start to smell odors in your vehicle, this is another indication that it's time to replace your cabin air filter. When changing your cabin air filter, be sure to take caution not to break any of the clips or pins that hold it in place. It's also important to note that rolling down windows in the middle of winter won't provide you with fresh air if your cabin air filter is dirty or clogged. By replacing your cabin air filter regularly, you can avoid breathing in unhealthy mold and keep your car smelling fresh.

This is one of the most overlooked maintenance items in a car, so make sure you don't forget about it!.
