Cabin Air Filter Replacement by gilvkona

I was replacing the filter on my 2006 RAV4 today. The filter that was there had an up arrow. The replacement filter had an airflow arrow. Does anyone know what direction the airflow is for this filter so I can replace it properly? Looking at the filter, I don't know how it could matter.
 
I called one dealer, he told me the flow was from the bottom to the top. The other dealer told me the opposite.

There is a cabin air filter, sometimes called a AC(air conditioner) C(cabin) filter. It is located right behind the glove compartment. The replacement directions are in the owner's manual at the end of the AC operations section. The dealer replaced mine at 15k miles. I now am replacing it myself at 45k miles. It is pretty dirty, I must admit. It is very easy to replace, no kidding.
 
A third dealer just told me the flow was from the bottom up. So there are two out of 3 votes in that direction. Looking at the filter, I can't see how it matters but who am I to tell.

It does matter because if the filter airflow is in the proper direction, the filter element will be tightly sealed by the airflow(for better filtering) and will also rest against any bracing. In the incorrect position, the filter willed be pulled loose and not afford a tight seal and will not be supported by any bracing.

OK. But can you help me by telling me what the airflow direction is? Is the airflow from bottom to top as 2 of the 3 dealers said?
 
Thanks for any help out there.

Don't take this as gospel but I can't imagine any Toyota/Lexus HVAC configuration wherein the airflow isn't downward. From the outside air intake at the bottom of the windshield toward/into the squirrel cage blower assembly below.
 
In recirculate a damper closes the outside inlet and opens an alternate cabin air inlet above the filter.

On page 381 of the 2009 Owners Manual, it indicates that there is an arrow on the filter that should be pointing up when the filter is installed.

As I said previously, the original has an up arrow. The replacement which I bought from the dealer has an airflow direction arrow. So they are different.
 
However, I concluded the flow is indeed down. I put my hand in the open space and turned on the fan. The air pull down as one writer expected it to be. Also, I could trace the tubing from the blower or whatever I am looking at and it goes to the vents on the dash thus confirming the flow. You really have to look at it to figure out what is going on. And once again, based on my looking at the filter and looking at it fit, I could have placed this either way and it doesn't matter, in my opinion.
 
At least next time, this will be easy.
