Benefits of Using the CU 3822-2 Set

• Enhanced Cabin Comfort: By filtering out pollen and fine dust, occupants experience cleaner air, reducing allergy symptoms and improving overall comfort.
• HVAC System Protection: Cleaner airflow reduces wear on the heating, ventilation, and air conditioning components, extending their operational life.
• Consistent Performance: The dual‑stage design ensures that even after prolonged use, the filters continue to perform at high efficiency levels.
• Cost‑Effective Maintenance: Replacing both filters simultaneously eliminates the need for separate purchases and guarantees balanced filtration across the cabin.

Installation Guide

1. Locate the Cabin Air Filter Compartment: Open the glove box or access panel as per the vehicle’s service manual. The filter housing is typically situated near the rear of the passenger compartment.
2. Remove the Old Filters: Slide out the existing filters carefully, noting their orientation to ensure correct placement of the new set.
3. Insert the Pre‑Filter: Place the first filter (pre‑filter) into the housing, aligning it with the airflow direction indicated by arrows on the filter or compartment.
4. Add the Fine Particulate Filter: Slide the second filter onto the pre‑filter. The design ensures a snug fit without the need for additional fasteners.
5. Secure the Compartment Cover: Close and lock the access panel, confirming that it is firmly seated to prevent air leaks.
6. Verify Airflow: Start the vehicle’s HVAC system and check for normal airflow. A noticeable improvement in cabin air quality should be evident.

Maintenance Tips

• Inspect filters every 12,000–15,000 miles or as recommended by the vehicle manufacturer.
• Replace both filters simultaneously to maintain balanced filtration performance.
• Avoid using compressed air directly on the filter media; instead, gently tap or brush off loose debris if necessary.
