Have you noticed an unpleasant musty smell inside your vehicle? If so, it’s time to address the issue before your passengers refuse to ride with you. The solution might be as simple as replacing your car’s cabin air filter. But what exactly is a cabin air filter?
While many are familiar with the engine air filter that keeps dirt and debris out of the engine, not everyone knows that their vehicle’s HVAC (heating, ventilation, and air conditioning) system also has a cabin air filter.
Just as the engine air filter ensures clean air reaches your engine for efficient operation, a cabin air filter performs a similar function for your car’s HVAC system. It prevents dirt, dust, pollen, bacteria, leaves, bugs, and other debris from entering the ventilation system, keeping the air inside your vehicle fresh and breathable for you and your passengers.
To maintain good air quality and ensure optimal HVAC system performance, you should replace your cabin air filter annually or every 12,000 miles. If you frequently drive in heavily polluted areas or on dirt roads, consider changing it every 5,000 miles. Those with allergies may want to replace the cabin air filter more often for improved air quality.
For the best results, replace your cabin air filter with a high-quality Champion cabin air filter, designed to remove 98% of airborne contaminants like pollen, dust, and road dirt. It features carbon-enhanced media for maximum odor control and is built for an optimal fit and performance.
Don’t worry; changing your vehicle’s cabin air filter is a straightforward task that anyone can handle. Follow these step-by-step instructions to replace your cabin air filter.
Step One: Locate your car’s cabin air filter. The cabin air filter’s location can vary from one vehicle to another. Some cars have it under the hood, while others position it behind the glovebox or under the dashboard. Your vehicle’s owner manual will provide guidance on its location. Alternatively, consult a trusted mechanic or professional to show you where it’s located.
Step Two: After finding the cabin air filter housing, remove the old filter. Take off any clips, screws, or wing nuts securing the housing in place. Remove the cover and then take out the filter. Inspect the old filter; if it appears dirty and grimy, it’s time for a replacement.
Step Three: Clean the housing compartment. Before installing the new cabin air filter, take a moment to clean the housing compartment and air intake duct. Use a vacuum to remove dirt and debris, and use a rag to wipe the inside of the air filter chamber to eliminate any dirt.
Step Four: Install the new cabin air filter. Place the new filter in the same location as the old one (ensure you install it with the correct air flow direction).
Step Five: Reattach the housing cover, securing any screws or clips you removed earlier. If you had to remove the glovebox or dashboard to access the cabin air filter, reinstall it by reversing the steps you took to remove it.
That’s it! You’ve successfully replaced your cabin air filter, providing fresh, clean air for you and your passengers. Plus, you’ll feel accomplished knowing you saved money by not having a dealership or mechanic perform the replacement.
