The era of performance cabin air filters really began in 1996 with the introduction of the W210 sedan in the U.S. market. By performance, we mean more than just a simple intake air box filter like you saw on the later model W124. A performance filter package contained two side by side paper element filters on top of (intake) the blower motor intake air box and two inline charcoal filters on the outlet side of blower box air box. These provided both clean and fresh smelling air to car’s occupants.

They were designed to be changed on a regular basis (every one to two years based on environment conditions). Unfortunately, time has shown that they do not get changed. When ignored you will have restricted air flow through your vents and in some cases foul smelling air. Why don’t they get changed? It may be due to the fact the owner is not even aware of the filters and the importance of their replacement. We think it may also be the same with some repair shops. Kent has never seen a 10 to 15 year old Mercedes with clean cabin air filters in both locations!
Replacement at first may seem like a lot of work, but if you know how to do it, it should not take more than 30 to 45 minutes. This is definitely a beginner D.I.Y. job. You will be amazed at the improvement in HVAC air flow and quality. This applies to the E320, E300, E420, E430, S430, S500, CL500 as well as the AMG models from 1996 to 2006.
