So my biggest complaint about the new to me ride is, the lack of a cabin filter. I work in the dust bowl. There is a daily smattering of ultra fine dust on my car every day when I leave the office.
How much of this dust is SUCKED into the car and into my lungs? Surely, Ford has decided to put a cabin filter in their newest sedan in their model line up. Nope.
Not only is air quality of concern, but its unhealthy for the AC system. Dust on the blower motor and evaporator core wreak havoc on the system.
However, they did have a cutout for where one SHOULD be.
So I checked around. The 2008 Taurus which has a cabin filter, uses a popular number, that many cars, including Acuras use. So I went out, picked up a cabin filter, and armed with my dremel and a fine toothed hacksaw, I went to work.
This mod is applicable to the 05-07 Ford Five Hundred, Ford Freestyle, and Mercury Montego. I am not responsible for you destroying your evap case due to poor decision making on your part.
You'll need to to get all your junk out of the glove box.
Next, you want to pull up on the button as shown here.
Now you have access to the evap case.
Notice Ford had made provisions for Cabin filter access cutout in the blower box.
You'll want to cut between the 2 ridges. All the way around. Dont worry about being perfect. Keep it between the ridges, youll be fine. Dont throw the piece you cut out away.
Now heres the cutout removed. Notice that Ford had every intention of having a filter here. Square opening, flat floor ridges, etc. Also notice the amount of dust in there. Blech. Windex and paper towel time.
So heres our new cabin filter installed.
Now heres the piece we cut out, back in place, and some Aluminum tape, holding it all in. Not the prettiest, but functional.
Now I can enjoy clean filtered air! Most manufacturers recommend annual replacement, so I'll check in a year from now and we'll take a look at that filter!
