The cabin air filter in the Mercedes-Benz E300L is located inside the glove compartment on the passenger side. The method for replacing the Mercedes-Benz E300L cabin air filter is as follows: First, locate the fastening clip on the right side of the glove compartment, press firmly on both sides of the clip to release it, and then you can proceed with the replacement. Below is an introduction to the cabin air filter: 1. Material: Activated carbon composite filter cloth, made from high-efficiency adsorption materials, activated carbon, and filament non-woven fabric. 2. Structure: Compact structure, effectively filters smoke, pollen, dust, harmful gases, and various odors. 3. Air purification: Capable of efficiently filtering and adsorbing particulate impurities to filter oil and purify the air.

With over a decade of car repair experience, I can tell you that the cabin air filter of the Mercedes-Benz E300L is hidden behind the glove compartment on the passenger side. The operation requires careful attention. First, you need to remove the glove compartment—common designs include clips or small screws at the bottom, which can be loosened with a small wrench or by hand. Once the filter housing is exposed, pry open the cover and pull out the old filter, paying attention to the directional arrow to avoid installing it backward. When inserting the new filter, align it with the airflow direction for efficient filtration. After installation, don’t forget to reassemble the glove compartment. It’s best to disconnect the negative battery terminal during the process to prevent short circuits, and wear gloves to keep your hands clean. Replacing it once a year ensures the air conditioning system stays healthy, especially during pollen season when you’ll notice significantly smoother breathing. Doing it yourself saves a lot on labor costs.

As an amateur DIY enthusiast, I found it quite interesting to replace the cabin air filter on my Mercedes-Benz E300L. The filter is located inside the glove compartment in front of the passenger seat. Gently pull out the front part of the glove box—some models allow it to slide out directly or require removing securing screws to reveal the filter compartment cover. After opening it, replace the old filter with a new one, making sure to align it correctly with the markings and secure it tightly. Be careful with the orientation, as incorrect installation will reduce filtration efficiency. Once done, test the AC airflow and check for any unusual odors—the whole process takes about 20 minutes. After a few tries, you'll become proficient. I also recommend buying the matching model online to save money—improving air quality is definitely worth it for a better life.

I've been driving a Mercedes for several years and always replace the air conditioning filter by accessing the passenger side glove compartment. Remove the bottom of the glove box to check for clips or screws, loosen them to access the filter housing, then remove the old filter and install the new one - make sure the airflow direction arrow isn't installed backward. After finishing, test the AC to ensure smooth operation. Performing this maintenance every two years helps prevent allergen buildup.
