How important is changing A/C filter at 15000 miles...A/C works fine no problems..08 RX 350....

 

The filter doesn't have anything to do with the a/c working "fine". Its purpose is to filter out bad "stuff" from the air. I believe it may even have activated charcoal embedded in it, or am I confusing that with my BMW? Anyhow, replacing the filter is a 10 minute job and easily done by anyone. Not trying to be a smart aZZ but they put the filter there for a reason and they put a life cycle change on it for a reason. If nothing else, pull it out, shake of the big stuff and rinse it off prior to reinstalling. However, they are fairly cheap, especially if you buy the no-name version from Auto Zone/Advance Auto.

Thank you...Where is that filter located on the 08 RX 350...

 

You open the glove compartment and pull out the two pins on the sides. It drops down and you can reach in and pull the filter out. Takes 5 minutes, if that.

 

Thanks, I will try and get that filter out and replace with a new one..

 

The RX cabin filters are hepa type microfilters, but not with activated carbon...we wish. But you can actually get the activated carbon type, somebody makes them to fit many cars.
