How to Clean Cabin Air Filter – Importance, DIY Guide, and Warning Signs
Introduction:
Do you know that the cabin air filter in your car plays a crucial role in ensuring clean airflow inside the cabin? Over time, this essential component accumulates dust particles and impurities, affecting air conditioning efficiency and even your health. Cleaning and replacing the cabin air filter regularly are essential maintenance tasks every car owner should know. In this blog, we will explain what a cabin air filter is, why it's necessary, when to clean it, and how to do it yourself. Additionally, we'll highlight the warning signs of a clogged cabin air filter that you should never ignore.
What is a Cabin Air Filter?
A cabin air filter is a rectangular-shaped unit, typically made of paper and multifibre cotton, installed inside your vehicle's cabin. Its primary purpose is to filter the airflow from the fan, capturing dust particles and impurities, and delivering clean air into the cabin. While often overlooked, this filter plays a crucial role in maintaining both your health and car's overall condition.
Why and When Should You Clean the Cabin Air Filter?
The cabin air filter traps various impurities and dust particles over time, causing it to become clogged. A clogged cabin air filter can result in poor air conditioning efficiency and an unpleasant odour inside the cabin during longer drives. To ensure optimal performance, Indian car manufacturers generally recommend cleaning or replacing the cabin air filter every 10,000 km or annually, whichever comes first. However, if you drive your car infrequently, you may be able to extend its usage by cleaning the filter and using it for a couple of months more.
How to Clean the Cabin Air Filter – DIY Guide:
Cleaning your cabin air filter is a simple task that can be accomplished without any special tools. Here's a step-by-step guide to help you do it yourself:
1. Open the glove box – Empty the glove box of its contents, such as the owner's manual and other items, to access the air filter.
2. Remove the stop arm – Locate the limiting stop arm, usually positioned on the right side of the glove box assembly, and slide off the pin to remove it.
3. Take out the glove box – Push both sides of the glove box inward to free the side clamps, allowing the glove box to hang downwards for access to the air filter.
4. Extract the air filter – Once the glove box is open, the front lid of the air filter will be visible. Gently pull the air filter out from the compartment, taking care not to scatter any dirt on the dashboard or seats.
5. Clean the old filter – To clean the filter, either use an air gun to blow away the dust or gently tap the filter sideways with a cloth-wrapped hand to remove most of the particles. If the dust is deeply trapped, consider installing a new air filter.
6. Reinstall the filter – Before reinstalling the filter, clean the chamber and inspect the seals. Once cleaned, place the filter back in its original position, ensuring it faces the right direction. Then, put the glove box back in place, fix the limiting stop arm, and you're all set.
Warning Signs of a Clogged Cabin Air Filter:
To avoid potential issues caused by a clogged cabin air filter, keep an eye out for these warning signs:
1. Ineffective cooling – If your air conditioning performance has declined, even at the lowest temperature settings, a clogged cabin air filter could be the culprit.
2. Persistent bad odour – While spills can cause temporary odour, if you notice an ongoing foul smell that intensifies with the air conditioning on, it's likely due to a clogged and dirty cabin air filter.
3. Hissing sound from the dashboard – A clogged cabin air filter restricts airflow, leading to hissing sounds originating from behind the dashboard. If you hear such sounds, prioritize cleaning or replacing the cabin air filter.
Conclusion:
Regularly cleaning or replacing your cabin air filter is a simple yet essential maintenance task that improves both your car's air conditioning efficiency and your overall driving experience. With our DIY guide and awareness of the warning signs of a clogged filter, you can ensure cleaner and healthier air inside your car cabin, protecting both yourself and your vehicle. So, why wait?
