Finally got this figured out. Its in. 99 4 runner but should work with the 80’s. Just changed it out for the first time and the filter was black. No dust on the interior.

Can you provide some more details on this? Is that under the vent between the hood and the windshield? How'd you install it? I've been wanting to do this for some time now (I'm in wildfire territory) and haven't seen a solution I've been happy with, but this looks promising!
 
A cabin filter that's actually in a practical location would be really good. The cabin air intake is under the removable scuttle panel (remove wiper arms, remove a run of screws normally hidden under rear lip of hood/bonnet, and it slips out) and there are three plastic clip-in grilles. That's the only 'filtering' an 80 series has of it's cabin air intake.

There is no 'practical' location under the dash for one. Some sort of commercial filter gauze might work if it's wrapped around those plastic clip-in grilles under the scuttle panel however that won't give the sort of fine airborne particulate filtering that modern vehicles have.
 
So steps i took after reading another thread on this. I actually posted this on the wrong thread. But here you go.

-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
-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 a hard job. This has been worth it due to the decreased dust and increased performance in cooling and defrost. I noticed 0 air flow drop. Let me know if you have any questions. Sorry i didn’t take more pics during project.

 
Or just do this easy win:
 
There is a great solution for this at solvefunction.com He has one for both LHD and RHD 80s and a replacement filter. Check it out and a lot of other really cool and functional products at:

 
I had an AC mechanic tell me one time; "You know when people complain about a musty smell in their car, it's the AC Receiver Drier that needs to be replaced". Not sure if anyone else can chime in on this.

Yeah that's a big negative.. the reciever drier is for the refrigerant and is located in the left front of the vehicle by the headlight... the evaporator is full of gunk and trash and water due to the nature of how air conditioning works... clean the evaporator and box of the trash and the smell should go away. What makes it worse on the 80 is the lack of cabin airfilter that allows gunk into the evaporator.

Having the rain water go into the filter doesn't mess it up at all? Not being critical, honestly curious.

Definitely would love a cabin air filter.
 
Hi all,
Decided to share my issue resolving to the lack of cab filter in 80 series. A/C dryer was packed by all kind of things and not working properly as windows started to get foggy, not enough air flow on air duct and weird smell.
Idea for modification was taken from eastern Europe LC enthusiasts forum and put to reality. This option allows to access cabin filter from under passenger leg room. Easy to clean up or replace.
Step 1:
Carefully masured and trimmed by Dremel or Proxon AC dryer box.
Step 2:
Heated by welding fan bottom plastic. Basically just straight 90° to avoid any air gaps.
Step 3:
Installed 1" wide thin steel profile on both sides and riveted (2 rivets on each side)
Step 4:
Thread rivet in bottom pieces of plastic and 1" aluminum angle drilled for holding up the filter. Plus made a little hole and leg for one side of that angle to sit in the frame.
Step 5:
Trimmed one side of cab filter and placed in.
Filter measurements: 157mm x 135mm + 6mm(1/4") foam weather strip on top.and bottom.
