Alternative for cabin air filter
 

Hello all. It's time to replace the cabin air filter in my trusty '97 S320. The car has the charcoal odor filter option, which means that the recommended cabin filter is the one with the carbon backing instead of the plain paper one. The problem is the carbon model is around $100 vs about $25 for the plain paper one.

Is there any technical reason why I can't use the plain paper one? They appear to be the same size and shape.


Carbon filter - $93.04:

Plain filter - $26.72:

The carbon does a better job, its your call. There are cheap oil filters, and cheap furnace filtes!

There is no technical reason why the paper filters cannot be substituted. Activated carbon does absorb odors more efficiently, but both will block dust and debris that enter the cabin intake system.

Yes, but the main purpose of the charcoal backed pollen filter, is to
lessen the stress on the main charcoal filter.
