Default DIY Cabin air filter replacement (RX350)

Having benefited time and time again from great advice offered up by other posters, thought I'd return the favor a bit by putting together a quick guide for replacing the cabin air filter for the second generation (2007 RX350 in my case). Pretty straight-forward process, please find as follows:

Necessary goodies:
  • Air filter -- I opted for the Fram FreshBreeze (model# CF10132). Not sure if the activated carbon does much, but it was conveniently available at Walmart, or online (e.g. rockauto.com). <$15
  • Pliers (optional) -- Ideally something with relatively wide jaws, I used a slip-joint.




Pop open the glove box and at the upper left and right hand outermost corners, there is a plastic pin. In reading some prior threads, these are usually very tight coming out of the factory, so I needed pliers to twist and loosen them. (To prevent damaging/scratching the pin with the jaws of the plier, the tabs can be insulated with a plastic bag.) The left pin was loosened in the counter-clockwise direction, whereas the right pin in the clockwise:


It appears the pin didn't have to be completely pulled out, just loosened a touch. Then, some gentle tugging on the walls of the glove box downwards/outwards allowed for its release. Here's the full pin if one were to disassemble it completely:


With the glove box released, the filter holder (white) is revealed. Push inwards on the left/right tabs to release the holder.


The filter holder with dirty filter membrane:


Empty filter holder ready for new filter:


Now, place the replacement filter in the holder, noting the direction of air flow -- air flows from top to bottom:


Snap the filter holder back in the chamber and twist-lock the glove box pins to complete the process.

Hope this helps!

its great that the cabin filter on the RX and most of not all toyota/lexus models are easy to change. The one in my C requires much more work.

Wouldn't be great if we could actually buy "Cabin Air Filters" not made in China? 3M Filterete (USA) did at one time, but as best I can tell they don't anymore. In any event your post is informative and spot on.

I recently replaced my cabin air filter with the Fram from Wallymart for $16. At 7 months old it was filthy. I'm glad I checked it. I'll have to recheck it after the leaves stop falling to see what it captures.

In retrospect, perhaps I should have replaced mine earlier than 30k! Didn't have too much in the way of leaves, the largest particulate was a dead bee

Eewww! No bugs, just leaf particles and probably lots of pollen for me. Then again I didn't check too thoroughly. Glad I didn't! It amazes me what can get inside, especially the taillights. What a collection I had in there.

just replace mine with one from NAPA auto store-$18.
I should have taken a picture of the one I took out. Leaves, bugs, pieces of debri and all the sand. I don't think it was ever replace. Now with the new one you can actually smell the difference. not that it smelled before-but you can now see and smell the difference-if that makes any sense. worth the $18

Does not hurt to check condition of the filter every 6 months at least.

Default Definitely do this DIY and save big $$$

Folks, DIY on this item is a no brainer. From what I understand, Denso actually is the OEM supplier to Toyota for this part. The Denso part number is 453-1011. About $16. (Note that the "Toyota" OEM part 87139-YZZ05 costs about $20 at Sewell if memory serves).) It literally took me two minutes, with no tools, to change out the filter by following the excellent tutorial above that started this thread. Total cost: $16. OEM part.

Bottom line: Do this yourself. Save yourself $ dollars. Save yourself an hour. Learn a thing or two in the process.

I bought half a dozen from cabin/ACC filters from ************ (both .ca and .com) and shipping was free if you spend $75.00. Service was amazing! I am in Vancouver and I ordered on-line at about 10:00 am. My package arrived the next day at 2:00 pm (about 30 hours).

These filters (Chinese-made) work fine. The original one picked up a lot of dust during a summer road trip and the car would smell musty in rainy weather.

I can't mention Auto()Parts()Way? Why not? Sewell's gets mentioned all the time.

Approximately how often do cabin filters need to be changed if the car is driven daily to and from work that is about 18 miles round trip?
