I have noticed that my charcoal filters start to smell after just a few months. I was buying three or four filters a year. I pulled them out and they weren't even dirty, just smelly. I am back on plain filters and no smell and I am only buying one a year.

 

It is the dreaded AC evaporator smell. It comes from using scents and they actually build up in the evaporator and then turns sour.

 

I just came from Lexus and they wanted $79.95 to do it! Thank you!!!

 

speaking of this Im starting to think mine needs to be changed as thats one of the few things that i havent done since getting my rx350 a little over a year ago now so i need to check and probably change mine. thanks for posting instructions too!

 

off topic , wonder why they cost so much compraed to engine air filters?

 

Any idea why the photos no longer appear on the first (very helpful) post by Prech on 10-19-10? Is my browser failing (Firefox 68.0.1 64 bit on Windows)? or is the connection broken to the server where the original photos were uploaded? Just wondering...thanks.

 

I have no idea,, I just changed the cabin filter out for a Wix carbon one a couple months ago.......IDK what a air filter goes for as I swapped out the engine a/f for a K&N panel filter......once & done.....
