Want cleaner air inside your Celica?

This simple mod will get you cleaner air for you to inhale inside your Celica. It will also reduce the dust and grim build up inside your car.

As you may not already know, the Celica comes with an air filter holder behind the glove box but does NOT have a filter installed to it.

From Toyota Parts Department, you can go buy a filter to put in the holder but they will charge you $21.95 or more. It's the same one that is used in the Toyota Solara.

Things you need to make your own air filter:
*3M furnace air filter (buy the best you can find) $7 - $11
*Good pair of scissors - garden clippers work best





Filters can be found at an home improvement center (HomeDepot, OSH...etc) for about $9. Buy the largest size since it is about the same price as the smaller sizes... And you will have enough material for about 4 filter changes (This works out to about only $3 per filter!)

The filter manufacturers claim it takes out 99.9% of all airborne particles including smoke particles.
That sounds good


Procedure:

Open your glove box...







Remove all the stuff from it...





3. Drop the glove compartment down by twisting the plastic knobs off inside the box - A half turn will get them into the correct position and then they just pull out. They are located near the top and sides of the glove compartment...







Remove the filter holder behind the opening...










Mine has the old filter from last time I did this - but yours will most likely be empty if this is your first time...




Without the filter...




....
....



Brand new filter...





Now prep your filter for cutting by taking it apart...





Since I bought a large filter, I cut mine into four parts so I could have another one ready when the old one needs to be replaced...








Cut the furnace filter so it will fit inside the holder. If you need to, clip the ends and clean up your filter's edges - just be sure not to cut your filter smaller than the actual tray. Try to make a good fit without any space on the sides where air can sneak past...



















When installing to the try, make sure the metal mesh is on the bottom. The air flows from the TOP to BOTTOM on the Celica....





This picture shows the filter upside down from the bottom...




The airflow direction should flow as directed by the filter manufacturer. Remember the air flows from the top to the bottom in the Celica.

Open side UP...





Grilled side on the BOTTOM...





Install filter hold back inside the Celica and put the glove box together. You are done

The air flow will be slightly less than before because of the added filter. But On the plus side, the blower noise is greatly reduced! If you have allergies, You will probably have no more runny noses and itchy eyes due to pollen when driving your Celica now. A worthy mod to do indeed!



Toyota recommends that the cabin air filter be changed every 15,000 miles if installed - but I would suggest changing when its no longer white and is now gray (in SoCal, that's about every 4 to 6 months)

Here is a pic of the filter after a couple months

I live on a dusty dirt road and had to dust my dash at least once a week until about a month ago when I did this install, since then I haven't had any crap build up on my dash. It's as easy as the S2000 antenna install; my only question is why does Toyota not have the Celica come with the filter? Could it be so that they can cash in on the extra money (not like they need it), or could there be any chance of added where on the blower? Thanks and enjoy (I have) [color=green] [/color]

it also comes as an option for $24 extra at the Parts Department.... Toyota recommends that the cabin air filter be changed every 30,000 miles if installed - but I would suggest changing when the filter is no longer white and is now grey (in SoCal, thats about every 4 to 6 months )

if you do not use the 3m filter and you just use the furnace filter it wont work after a while, it will jam the in/out switch so you cannot switch inbetween using outside or inside air...

CelicaRacer05, that is FALSE information...

The only way to have happen what you've described, is if the filter was installed UPSIDE-DOWN

ANY Brand will with a grill work - does NOT have to be 3M - All brands have some type of grill to keep the filter in the desired form

Since the air flows from TOP to BOTTOM, the correct installation is...

Open side UP...


Grilled side on the bottom...

Great and easy mod....

One thing i did a little extra is put one of those flat and sticky air fresheners in there... No one can figure out how my car smells so nice and where the scent is coming from...

Later,

Nice post Isaac, 11.99 for 4 cabin filters. Could be better filtration as well!?!

Yo, UPDATE:
I was clowning the L.A. guy for how dirty his filter was, but now I've got nothing to clown aboot.
And I'm in Seattle! and heres what mine looked like after not even a month. (granted when I read this thread and checked mine, there was NO filter, but still, ECCK!)
