Cabin air filter in 3rd gens?

We'll, the title pretty much sums up my question. Does anyone know if our 3rd gens have a cabin air filtration system? I read that many companies started using them in 2000.

I think I've seen it on the 1st gen Tacomas and they did something like cut up a house air filter to fit somewhere in the HVAC system. At least that seems familiar.
 
There is something...

There is an auxiliary cabin filter that was offered in Japan for the 3rd Gen. It replaces the overhead door light and filters in cabin air. Toyota afterwards developed its Ion and Minus Ion in cabin systems. Why never offered Stateside is anyone's guess.

Second shot

I always have an issue attaching multiple pics but here is a close up. You can see the different light setup in addition to the modes of the filter system

Here is one of the two prominent models, one I believe can affix to the rear of the 3rd Gen where you have the four plastic caps in the roof. Only OEM option I came across for this was a fishing rack Toyota offered. Believe the second generation unit attached here is installed on a Prius.

This is the one I believe attaches without much issue to the red of the 3rd Gen. There's also a switch made for these you can put in the dash. New they retail for about $200 and are very effective filter systems.

It would be awesome to incorporate a cabin filter into the HVAC system, my gf would certainly appreciate it come ragweed season! I might start tinkering around with some ideas, using some sort of universal sized micron air filter.

How would this work since the air comes in through the vents? By the time the filter does anything Ive already breathed the air coming from the vents
 
Correct

These are all secondary systems filtering air already present in the cabin area. So it's not the AC filter but a standalone.
 
Cabin filter solution

So I know this is an old thread but just wanted to share the project in case anybody wanted to take it on. It takes some effort but this solution works flawlessly. Enjoying dust free air and interior cleanliness. Don’t know if I would do it again but I like a challenge and was determined to figure it out during the winter when I had some down time. Here is what I did.


-I removed plastic cowl
-The opening on the drivers side is an exact match shape wise to the section on the passenger side.
-I marked the area in the exact shape and used a uni biand saw to cut the access
-Air intake is oval with 1 flat corner on firewall side.
-I used a piece of aluminum and cut it large enough to cover the hole but small enough to clear wiper motor.
-I cut a square hole the exact dimensions inside the aluminum cover to accommodate a cabin filter for a 2016 - up Jeep Wrangler.
-I used 1” aluminum angle to make a filter rack and used heavy duty silicon the seal everything up.
-I checked clearance occasionally by turning wipers on.
-I temporarily sealed up the access hole with Butyl flashing tape not asphalt based due to odor
-I am working on a permanent solution for an access panel but the flashing is working great and is completely covered by the plastic cowl.

As stated above. It requires effort but is definitely not overly difficult. This has been worth it due to the decreased dust and increased performance in cooling and defrost. I noticed minimal air flow drop on fresh mode. Obviously recirc mode is the same since it doesn’t pass through the filter. Let me know if you have any questions
