Learn when and how to replace the cabin air filter on your Rivian R1T or R1S. Includes step-by-step instructions, common mistakes, and filter recommendations.

Quick Answer

Replace your Rivian R1T or R1S cabin air filter every 12,000 miles or once a year, and more often if you drive in dusty or polluted areas. The process takes about 15 minutes and requires no special tools.

Why Cabin Air Filter Replacement Matters

The cabin air filter in your Rivian cleans the air that enters the cabin through the HVAC system. Over time, it collects dust, pollen, and other particulates, which can reduce airflow and allow odors to develop. Replacing it regularly keeps the cabin fresh and helps your HVAC system run efficiently.

Rivian recommends a specific interval, but your driving environment matters too. If you frequently drive on unpaved roads, in heavy traffic, or in areas with high pollution, consider replacing the filter more often.

Choosing the Right Filter: HEPA vs. Activated Carbon

When selecting a replacement filter, you have two main options: standard particulate filters and HEPA filters with activated carbon. HEPA filters capture a higher percentage of fine particles, while activated carbon helps absorb gases and odors.

The Abstract Ocean HEPA+Activated Carbon Cabin Air Filter combines both benefits. It uses a HEPA H11 element that removes 99.976% of particulates greater than 0.3 microns, including pollen and allergens, and the activated carbon layer captures volatile organic compounds and gases. The trade-off is a minor restriction to airflow, which is usually unnoticeable in normal driving.

If you or your passengers have allergies or you frequently drive in smoggy areas, a HEPA filter is a worthwhile upgrade. If you only need basic filtration, a standard filter will cost less but won't offer the same level of protection.

Step-by-Step Replacement Process

Gather Tools and New Filter: You'll need a flathead screwdriver (or trim removal tool) and the new cabin air filter. Ensure the new filter is the correct size for your Rivian R1T or R1S model year. Double-check the filter part number against your vehicle's model year before starting.
Access the Filter Housing: Open the front passenger door and locate the filter housing behind the glovebox. You may need to remove a trim panel or the glovebox itself to access it. Consult your owner's manual for exact location. If the trim panel feels stuck, use a trim removal tool to avoid breaking clips.
Remove the Old Filter: Carefully pull the old filter out, noting the direction of airflow indicated by arrows on the filter frame. Dispose of it properly. Check the old filter for debris or leaves; if heavily clogged, consider replacing it more frequently.
Install the New Filter: Insert the new filter with the airflow arrows pointing in the same direction as the old one. Ensure it sits flush and fits snugly in the housing. If the filter doesn't slide in easily, it may be upside down or reversed—do not force it.
Reassemble and Test: Reinstall the trim panel or glovebox, then start the vehicle and turn on the HVAC fan. Check that air flows freely and there are no unusual noises. If airflow seems weak, recheck the filter orientation and seating.
