4. Installation Guide

Replacing your cabin air filter is a routine maintenance task that can be performed with basic tools.

Refer to your vehicle's owner's manual for the exact location and specific instructions for your model.

General Installation Steps:

1. Step 1: Locate the Cabin Air Filter Housing

   Typically, the cabin air filter is located behind the glove box. Open the glove box and look for release tabs or screws that allow it to drop down or be removed. Some vehicles may require removing a lower dashboard panel.

2. Step 2: Remove the Housing Cover

   Once the glove box is out of the way, you will see a rectangular cover for the filter housing. Unclip or unscrew this cover to expose the old filter.

3. Step 3: Remove the Old Filter

   Carefully slide the old cabin air filter out of its slot. Note the direction of the airflow arrow on the old filter, as the new filter must be installed in the same orientation.

4. Step 4: Install the New Filter

   Insert the new EPAuto CP173 filter into the housing, ensuring the airflow arrow on the filter points in the correct direction (usually towards the rear of the vehicle or as indicated by the housing). The flexible design of this filter allows for easier insertion into tight spaces. Once fully inserted, replace the housing cover and reassemble the glove box or dashboard panel.

5. Maintenance and Replacement

For optimal performance and cabin air quality, it is recommended to replace your EPAuto CP173 Cabin Air Filter every 12 months or 12,000 miles, whichever comes first. However, replacement frequency may need to be increased if you frequently drive in dusty conditions, areas with high pollution, or if you notice a decrease in airflow from your HVAC system or persistent odors in the cabin.

7. Troubleshooting

• Reduced Airflow After Installation:

  Ensure the filter is installed with the airflow arrow pointing in the correct direction as indicated by your vehicle's housing or owner's manual. A clogged or incorrectly installed filter can restrict airflow.
• Persistent Odors:

  If odors persist after installation, ensure the filter is properly seated and the housing cover is securely closed. If the issue continues, consider if other sources of odor are present in the vehicle or if the HVAC system itself requires cleaning.

• Filter Does Not Fit:

  Double-check the compatibility list and your vehicle's exact make, model, and year. While this filter is flexible, forcing it into an incompatible housing can damage the filter or the vehicle's components. Verify the part number against your vehicle's requirements.
