What Are Air Car Filters?
Air car filters clean the air before it enters the engine or cabin. There are two main types of filters:
- Engine Air Filter: This filter cleans air that goes to the engine.
- Cabin Air Filter: This filter cleans air inside the car where people sit.
Both filters need to be clean for your car to work well. Dirty filters can cause problems. The engine may not run smooth. The air inside the car may feel dusty or smell bad.

Why Should You Clean Air Car Filters?
Cleaning filters has many benefits:
- Helps the engine get clean air.
- Makes the car use less fuel.
- Improves air quality inside the car.

If you do not clean filters, dirt builds up. This blocks air flow. The engine works harder and may get damaged. The cabin air will also be dirty and cause allergies.
Tools You Will Need to Clean Filters
You do not need many tools. Here is what to prepare:
- A screwdriver (usually Phillips or flathead)
- A soft brush or old toothbrush

Make sure your car is parked in a safe place. The engine should be cool before you start.
How to Clean the Engine Air Filter

Step 1: Find The Engine Air Filter
Open the car hood. Look for a black plastic box near the engine. This is the air filter box. It usually has clips or screws.

Use the screwdriver to open the clips or screws. Carefully lift the cover. Do not lose the screws or clips.
Step 3: Take Out The Air Filter
Lift the filter out of the box. Look at it. If the filter looks very dirty, it needs cleaning or replacement.
