Where is the cabin air filter located in my 2009 Honda Accord?

The owners manual says it needs to be serviced but It does not say how to find it. Says let dealer do it. Anyone know?

Most likely in the glove box.

Its usually behind the glove box. You need to fully open the glove box in order to access it
