The BG is to the point I am just fixing nitpicks, and rough ends. I was trying to best pollen season this year and wanted to install a cabin filter in the stock air-box housing and have it be about a half an hour service to change. This,to me, means not having to remove the fan housing.
The clearance near the blend door does not offer any room for a filter, so jamming it up there with the fan removed is also out of the question. This left the area between the Evaporator box and the fan housing box. The EVAP box would provide adequate room if the box were, square, and didn't have expansion valve tubing making flat mounting impossible.
So the easy answer was the output of the fan going into the evap, because it was not tapered, and the material seemed much stiffer. Additionally if I botched hard enough, it is much easier to just remove the blower housing.
The scribbled measurements I have for the output is 6 1/8 x 3 3/8 x1"
I do not recall why I measured it in standard.
The closest filter I found was a WIX filter 49093 7.13x3.61x0.8"
I was going to order that filter, but it was made in china so I just bought the cheapest ebay filter. The interchange is a 2008-2012 Jeep Liberty or 2008-2011 Dodge Nitro.
You get 2 filters in a box for $8.
You get to ruin one and not have to buy another.
This is how the filter fits in the housing with out any modification.
This is is trimmed down.
This is it having the felt edges re-glued.
This is it with the blower on high.
Despite being a snug fit, it blew right out of the housing into the evap.
I then just cut off about 1.5" of the fresh filter and jammed it in the housing. Using a flatblade screw driver to get it to spread into the corners and have decent pleat consistency.
This is the filter 4 weeks later on my inspect and instillation polish, I would remove it to see how many particulates it has gathered, but removing the filter will destroy it, as can be seen by the small filter here.
I then wrapped the connector with HVAC tape, which I have been doing for around a decade now to minimize leakage from the junction.
Bonus protip, replace the left side trim bracket's hex bolt with a screw bolt so you don't have to wiggle a slimline wrench behind it.
All closed up.
How it looks if you aren't running the trim piece under the dash. I am missing a blower box nut.
I'd recommend not doing this IN CAR, as I botched the cut a bit, and got impatient and now have a gash I will have to look at until the end of time. Here is how you should cut it outside of the car.
The piece stays in place well with out tape or the metal band as long as the blower isn't on, the top tab doing most of the work.
The blower noise is much quieter now, you can actually hear the motor itself and not the squirrel cage save for when it is on setting 4. The airflow from the vents has taken a marginal hit, I would say setting 1 would now only be usable on a very temperate day. Setting 4 is still more air than you need,setting 2 will likely stay my go to.
I will likely pull this filter after the fall, when I do the usual leaf removal from the blower housing and Cowl.
