Changing the cabin air filter in your 2020 Jeep Grand Cherokee is one of the easiest ways to keep your vehicle’s interior clean and fresh. Many drivers ignore this small part, but a dirty filter can lead to bad odors, reduced airflow, and even allergies. With a few simple tools and about 15 minutes, you can replace your filter and breathe better inside your car.
Why Cabin Air Filters Matter
The cabin air filter removes dust, pollen, and pollutants from the air entering your Jeep. If you drive in cities or dusty areas, this filter gets dirty fast. According to EPA studies, indoor air quality (including your car) can be two to five times worse than outdoors. A clogged filter reduces your HVAC efficiency and may make the air smell musty. Replacing it every 15,000–20,000 miles keeps your system running smoothly.
Tools And Parts Needed
You only need a few items:
- New cabin air filter (OEM or aftermarket)
- Flathead screwdriver (optional)
- Clean rag or vacuum
Prices for filters range from $15 to $40. Make sure your replacement matches the 2020 Grand Cherokee. Most brands list compatibility on the package.
Step-by-step: Changing The Cabin Air Filter
Changing the filter is simple. Here’s how:
- Turn off your Jeep and open the passenger door.
- Locate the glove box. The filter sits behind it.
- Empty the glove box. Remove any items to make space.
- Detach the glove box. Look for the side arm (dampener) on the right. Pop it off gently. Squeeze the sides of the glove box inward to release the stops, then lower it fully.
- Find the filter cover behind the glove box. It’s a rectangular plastic door.
- Open the cover by pressing the tabs. Pull it off.
- Remove the old filter. Pull it out slowly—dust may fall.
- Clean the area with a rag or vacuum to remove debris.
- Insert the new filter. Make sure the airflow arrow points down.
- Replace the cover and snap it in place.
- Reinstall the glove box. Attach the dampener and push the sides back to fit the stops.
- Close the glove box and enjoy cleaner air.

Comparison: Oem Vs Aftermarket Filters
Choosing the right filter matters. Here’s a quick comparison:
| Type | Price | Filtration | Durability |
|---|---|---|---|
| OEM | $30–$40 | High | 12–18 months |
| Aftermarket | $15–$25 | Medium–High | 10–15 months |
OEM filters offer better fit and filtration but cost more. Aftermarket filters are affordable and often work well, but check reviews for quality.
Signs Your Filter Needs Replacing
Don’t wait for problems. Here are common signs:
- Reduced airflow from vents
- Bad smell inside the car
- Foggy windows more often
- Increased allergies or sneezing
- HVAC noise louder than usual
Some drivers miss these signs. If you notice any, check your filter.
Practical Tips For Beginners
Many people make mistakes when replacing the cabin air filter. Here are two insights:
- Don’t force the glove box. If it won’t lower, check for hidden screws or clips.
- Check the airflow direction. Most filters have an arrow; install it facing down.
Also, keep your hands clean to avoid staining the filter.
How Often Should You Change It?
Jeep recommends replacing the filter every 15,000–20,000 miles. If you drive in dusty areas or have allergies, consider changing it every year. Some mechanics check the filter during oil changes—ask if yours does.
Here’s a quick mileage guide:
| Condition | Change Interval |
|---|---|
| Normal driving | 15,000–20,000 miles |
| Dusty areas | 10,000–15,000 miles |
| Allergy-prone | Annually |
Common Mistakes To Avoid
- Skipping cleaning before installing the new filter. Dust can build up.
- Installing the filter upside down. Always check the arrow.
- Forgetting to reattach the glove box dampener. This can cause rattling.
- Using the wrong filter size. Double-check the part number.

Replacing your filter brings real advantages:
