I looked at eBay and I calculated that the total was about the same if I went with Sewell or eBay as I need to get both air and cabin filter for my RX.

Air flow
Air flow is from the top to the bottom (outside air to fan intake). There is no housing on my 2011 450. On my OEM filter the bottom of the filer (fan side has what looks like fine dryer lint on it and the top side (air inlet) does not.

Mine went from White to complete gray/ black and mold except for parts on the sides. It's disgusting.

As I did this myself today I thought I'd make the correction here. According to the 'Do it yourself' section in the main manual, the arrow on the filter should point 'up'.
Had I not read it I would have assumed as you did and the flow should be down. That's correct but you can make out a cone shaped venturi just above a fan just below the filter after you remove it. But evidently it's pulling the air down as I had 'moths' on top of the filter as well. So the arrow parts to the top as that's the supply side of the filter.

I followed the various instructions in the forum with no trouble except for a minor detail: The original 2010 Lexus Filter was marked with an "Arrow" and its label was "UP" (the arrow pointed toward the top of the housing originally). However, the Purolator C35667 cabin filter I used ( it fit fine) has a printed arrow and a label of "Air Flow" as its marking. Given that the debris on the old filter was on the top of the removed filter (as it was pulled out), I assumed the Air Flow is from Top to Bottom - hence the new Filter would be installed with the Arrow DOWN, to match the airflow in the housing. Aside from being confusing, does anyone see a problem with this?

It's ok but by the time they charge freight it's kinda expensive. I just drove to my local Advance Auto Parts and bought their top line version for $20 bucks and installed it right their in the parking lot to make sure I had the right one. 5 minutes later I was driving down the road. Clean, simple, & cheap

Changed it for the first time today. It was surprisingly easy to do. Took more time emptying and putting back all the junk my wife keeps in the glove box. Much easier then our old RAV 4. On the RAV you had to remove the whole glove box to access the filter.
I used the WIix filter (#24483). At 19K it was really dirty. Went ahead and changed out the engine air filter also. It was also pretty dirty. Of course we did just get back from West Texas Big Bend area. Lots of sand and dust out there.

I changed the cabin filter today too. It was looking pretty sad. Pollen has been off the chart for weeks. I used the the same Wix filter as TomT127. I like it because It has more pleats than Toyota. Can't beat the price either, $11.

GRPFAN, over the past year I've switched between OEM and Wix with no effect on air flow. Earlier in this thread when I mentioned the extra pleats on the Wix I had just installed, you said 'it should work fine.' Others have used Wix with no problems either. With pollen off the charts and the AC being used more often, I wanted something a bit more substantial than the OEM filter.

Can any one show me how to replace the Cabin Air Filter in 2010 RX350?
I read in here that you need to switch to the ReCirc mode but then how to remove the shelves in the glove compartment? I almost broke it another the day but still can't take it apart.
Please help. Thanks.
