My former '02 SF did NOT come with the cabin filter, much to my surprise! I did install one once I noticed that the slot was empty. Didn't really notice much of a difference but since I spent so much time in that car I figured it was important to have decent airflow in the cabin.
I now have a 2010 SF and haven't yet checked if there is a cabin filter installed in it. The dealership says there should be one.
My Dads 2004 santa fe 3.5 did not come with a filter but did have a slot for it. there was mildew, dirt and debris all over the little radiator fins of the condenser or whatever those coils are. You have to be very careful as those little metal fins can bend easily. if they all bend up or down you will restrict the airflow.
All their dash airducts had dust and black and brown soot . I spent the whole day with coil cleaner where the airfilter should have been and a spray bottle with water with a wet dry vac. Also used lysol on all the ducts and ran a micro fiber cloth with lysol on a bendy appliance brush through the dash face level ducts. It was disgusting. I cant believe they wouldnt install one at the factory. My Dad had no idea there wasnt one in there and my mom and him have been breathing crap for 7 years. I recommend everyone put one in and clean the $hit out of the ducts if you never had one in the first place. You can pop off the covers on the side vents on the dash wich feed the door vents. Thats where I fed the brushy thing. You could probably use a duct cleaning kit that goes on a dril at very low speed if the brushes are soft enough with whit the wet dry vac hooked up and the other vents blocked off except for one other so the air can flow but what I did worked fine. I sprayed the dash ducts and side duct feeder with lysol, then I sent the appliance brush with the micro fiber rag doused in lysol (duct taped to appliance brush) across the vent from each side of the dash towards the middle where the two vents are on the center console. Did both drivers and passenger side in a twisting motion. You cant make the brush too big or it wont fit in the ducts from each side on the dash. the passenger side had more room in the duct than the drivers side. Might be less clearance due to smaller ducts or turns to go around the instrument panel on drivers side. At any rate my parents were always sneezing and now I know why. Should have taken pics but trust me when I say it was disgusting.
If you are behind the glove box, which side does the air flow? DOes it flow from passenger to drivers side or the other way across those coils? The coils were on the left of the opening where the filter goes if I looked in sitting on passenger side facing glovebox. Why do those filters have a direction? The medium looks the same to me on either side.
