Do the ridges on the cabin air filter go up, or down?

I ask because a mouse chewed through it, and the glove compartment, and left calling cards all over the interior of the car (insert evil mouse smiley here).

The service guy cleaned out the old filter and ordeed a new one. I installed the new one, but am directionally challenged, not having seen the original.

There is now a mouse trap under the Prius, and yesterday I caught a big one.

Thanks,

Scott

I believe that the ridges go up.

Mine are facing up. The paper flange is on the bottom and slips under some small clips, front and back.

Your question inspired me to go out and clean the leaves & debris that had accumulated on mine in the last several months. These things get dirty quickly. There are some interesting posts about alternative filter materials either here or on PriusChat. I'm considering using some of the washable foam since my factory filter is looking pretty bad....

Thanks! Yes, I saw the discussion on filter alternatives: good idea given the cost from Toyota.
