So, I feel really dumb. I bought a new carbon air cabin filter for my Rx330. I found the filter no problem and removed it. Took the new one out of the box and went to place it back in the tray. I have no clue which way to put it in. After I do get it in....does the arrow on the tray point up toward the top of the car or down. Which way is the air flow?

sigh.........

I thought I could do this one without help!

I made one of my own over the weekend using a 3M hepa filter from Home Depot for about $10. I believe it faces up. (Flows from bottom floor and goes towards the top to the roof)

 

The arrow points up.

 

Yes the arrow points up....I was also confused...better put a marker when installing, the arrow sign is so faint.....

 

THANK YOU..... I did it right. I noticed that when I hit the "AUTO" button to cool off the car it was taking a long time to get up to speed. Seems like the air flow is slowed down dramatically by the filter. I am starting to wonder if the charcol filters are just to dense for the car.

I had it in the right direction. I removed it to look and was amazed at how much the air flow was restricted. Should I can the carbon filter?

Thanks again....

 

How much did you pay for it, did you get it from the dealer?

 

I paid about $30.00 for it from an online site recommended on these boards.

 

It is OEM then. Carbon helps with the odor control.

 

I know some cars (my moms E320) can automatically detect outside air quality and decide between re-circulate and circulate does our RX have this feature? How to turn it on? its a 04 btw

 

no not available on the RX. it automatically switches to recirculate and circulate depending on temperature and fan speed and blow location.

only newer lexus models have the smog sensor and even then its not all Lexus models. only the higher ends. as an example, the IS350 has a smog sensor, but the IS250 does not

 

bummer oh well.
