Cabin Air Filter – 4478300000 | Mercedes Sprinter HVAC Dust & Pollen Filter

SKU: 4478300000 - qty 1

Breathe cleaner, fresher air inside your Mercedes Sprinter with this Cabin Air Filter – part #4478300000. Installed in your van’s HVAC system, the cabin filter traps dust, pollen, allergens, and airborne particles before air enters the interior, helping protect passengers and keep the heating and air-conditioning system running efficiently. Over time cabin filters become clogged with debris, reducing airflow, causing odors, and making HVAC systems work harder. Replacing your old filter with this direct-fit OEM-style cabin filter helps ensure fresh air, improved air quality, and better overall comfort for drivers and passengers alike. 

✔ Essential HVAC Protection & Comfort

• Prevents dirt, pollen, and environmental contaminants from entering your Sprinter’s cabin. 

• Helps maintain steady airflow and comfortable interior air — good for allergy sufferers and everyday drivers alike. 

✔ Durable, Easy-to-Replace Design

• Designed to fit directly in the Sprinter’s HVAC intake — straightforward to install during routine maintenance. 

• Compatible with vehicles that use this part number in place of other common cabin filter part numbers like 9108301100 / 9108301200 and similar OEM designs. 

✔ Recommended Maintenance Part

• Regular replacement keeps your HVAC system working smoothly and helps avoid odor buildup or reduced A/C performance due to clogged filter media. 

• Best replaced as part of routine service every 15,000–30,000 miles or more often in dusty environments. 

📌 Fitment Tip: Always check compatibility with your Sprinter’s year, VIN, and HVAC system — some model years and trims may use alternative cabin filter part numbers.
