Yes. The 2014 Mercedes-Benz E350 includes a cabin air filter as part of its HVAC system. In many markets it uses an activated charcoal pollen filter to improve cabin air quality, and the filter is located behind the glove box for replacement.
Cabin air filter in the 2014 E350
The cabin air filter is a standard component of the 2014 E350’s climate control system. Depending on market and trim, it may be a simple pollen filter or an activated carbon version designed to reduce odors in addition to filtering dust and pollen. Access and replacement are typically straightforward for a DIY enthusiast with basic tools.
Location and access
In the 2014 E350 (W212), the cabin air filter sits behind the glove box on the passenger side of the dash. Access usually requires lowering the glove box by releasing its sides or damper, then removing the filter housing cover to reach the filter itself.
To locate and replace the cabin air filter, follow these steps:
- Park the car, turn off the engine, and open the glove box.
- Gently squeeze the sides of the glove box to release its stoppers and let the box drop down.
- Locate the rectangular cabin air filter housing on the passenger side of the dash and release the clips or screws holding the cover.
- Remove the old filter, noting the airflow arrow direction printed on the filter frame.
- Install the new filter with the arrows pointing in the direction of airflow, reseat the housing cover, and secure the clips/screws.
- Lift the glove box back into place and close it securely; start the engine and run the HVAC to confirm proper airflow.
After replacement, reassemble any removed components correctly and test the HVAC system to ensure the filter is seated properly and airflow is normal.
Filter type and maintenance
Most 2014 E350 models use a cabin air filter designed to keep dust, pollen, and odors out of the cabin. Some markets offer an activated carbon version for enhanced odor filtration. The exact configuration can vary by market and optional packages.
Maintenance guidance and replacement intervals can vary, but typical recommendations are:
- Replacement interval: about every 15,000–20,000 miles (24,000–32,000 km) or once a year in normal driving; more frequent changes may be needed in dusty or polluted environments.
- Signs you need replacement: reduced airflow, unusual or musty odors, increased pollen exposure inside the cabin, or the HVAC system sounding louder than usual.
- Orientation and disposal: always install the new filter with the airflow arrows aligned correctly, and dispose of the old filter according to local waste guidelines.
In short, yes—the 2014 E350 has a cabin air filter, and it’s accessible for replacement with standard DIY steps or a quick visit to a shop or dealer for service.
