The computer that controls the A/C opens the "recirculate" flap on the air handler box so that when in the cooling range of the temp control (all the way counter-clockwise through about three or four clicks clockwise from there) the air is sucked from both inside and outside sources. The inside source air does not go through the filter...

This makes sense as the only filtering that is needed should be for the outside air, and this prevents a blocked filter from messing with the A/C...

And once more: The airflow in the xA/xB through the filter tray is TOP TO BOTTOM. If you want to verify that, look in the repair manual, or even better, simpler, and cheaper: Pull the filter tray out, turn the blower on high, and feel the airflow for yourself CAUTION: Don't stick anything into the fan - it is directly below the filter tray.

Now stop and think about this for just a moment. It is designed with a TOP DOWN flow through the filter so that the stuff the filter traps lays on the top of the filter instead of falling off the bottom every time the blower is turned off. Any filtration system that collects debris on the bottom of the filter is poorly designed...

Lastly, if you still don't believe, ask anyone who has a filter installed in the tray which side the debris is on - top or bottom. That's the side the incoming air is coming from...

(There are several other threads here on ScionLife where this is discussed at length.)

Wow!

I changed my earlier input to the correct information. My hands must not be as sensitive as they used to be. Used a piece of paper this time, and the air is flowing down as you say (Tamos), and I went out and changed my filter around. Thanks for pointing that out.

Default tC Cabin Filter

My tC has a different glove box than described so far. Can someone explain in detail how to remove the glove box to access the filter box?

Which way does the air flow... Ive had a 3M Filtrete one cut into my car for several months now, and looking at the pictures of the first post, it looks like mine is upside down compared to his/hers...

does air flow from the bottom ^ up... or from the top down???

Just a few posts above your question is your answer:
https://www.scionlife.com/forums/vie...075440#1075440

That, and the post following it should provide you with the information you need.

i just wanted to put in my .0001 cent that why weren't we ever told that there were NO cabin filter included when we purchased the car?

Our Home Depot does not have the Web Absorber, will look for it at Wal Mart

Awesome ideas! I just bought a carbon/fiberglass filter for a kitchen range hood, and came across this. Guess what... the kitchen's gonna be stinky until I get to Home depot again!

I also have a can of gel air freshener. Used it on USAF jets (now there's a stinky place). The benefit is it lasts forever! I'm sure up to the time it's due a new filter.

Can't wait to pass those dumps now!

There's not reason to make a home made filter. I bought one at my local import parts store for about $7 last October.

The filter is the same size as a Toyota RAV4.

I see you have a tC rather than an xA or xB.

Try here for the part numbers - there are multiple places where these have been posted over and over again on ScionLife, this is one of 'em:

https://www.scionlife.com/forums/vie...412394#1412394

There is also a decent discussion of the filter in a tC there (and several other places on ScionLife, too!!!)...

Picked-up a WEB odor control filter for $9.97 at Lowe's like Satmax and cut into 7 filters.

Thanks.

Default Dryer Sheets in Filter

I'd recommend skipping the dryer sheets for two reasons. First, it will shorten the life of your filter because it's adding the oil/syntheticwould ordinarily coat you clothes* to the cabin air or directly to the filter, depending on which side of the filter you put them on. Second, that stuff isn't very good for you to breathe. It's got all sorts of fun chemicals that are linked by some to pretty serious health problems.

*Dryer sheets work by coating the clothes so that they don't actually rub against each other's surfaces and don't generate static electricity. They don't absorb or eliminate odors, they just cover them. The perfume smell is the oils(whatever) evaporating and floating around. Obviously the world is full of pollutants but you're potentially putting yourself in regular concentrated contact with this stuff on your daily drive. Same is true of aerosol (and probably all) air fresheners.

Thanks for the how to on filter construction though. I hope to receive my xB in a week or two and I'll have to do this then (without the fabric softener!).

I picked up a Filtrete Allergen Reduction with a MERV 11 rating in 20x25x1 so I can get 6 filters out of it. I also got a Purity home air filter same size because it has a charcoal layer. I took the cardboard off of the Filtete after cutting it, the Purity has a plastic grid you can cut to size to make a good top. I then layered the Filtrete on top of the Purity with the plastic grid on top, duct taped all around and slapped it in. The plastic grid slips under the tray tabs great to hold it in. Hopefully this gives me some nice clean air!

I did this DIY mod a couple of weeks ago and it's the greatest, simplest mod I've done. I used all of the mentioned filter materials (charcoal to Hepa) in combination and it allows me to have nice fresh air even when following a deisel. Thanks for the info. kudos to the mad scientist!
