valmundo Just watched the entire Youtube video and purchased the cabin air filter from Amazon for $15 bucks. The swap took literally 5 minutes for me to do! Bravo to the author of the video. My dealership wanted to charge me $179 to change the cabin air filter, air filter, fuel filter and oil change. Really?

mechanizeddeath Finally had a chance to replace the filter on my Focus. What a difference between old and new. I think only the guy with the dusty road/foundry environment had a darker filter, but mine also had a ton of debris trapped in the pleats. Leaves, seeds, insect parts, you name it.

HVAC system seems to move a lot more air now, and although I hadn't noticed it, there was a slight musty odor that is gone now.

Best of all, filter removal was a lot easier than I expected after watching that YouTube video. I think I spent more time trying to get the cover back on than I did changing the filter, and that was only because I was trying to put it on backwards for some reason.

mechanizeddeath I can't wait to try this. The entire time I've owned my Focus, one of my few complaints has been that the HVAC system doesn't seem to move a lot of air, regardless of the fan speed setting. It just seems to increase the amount of noise coming out of the dash rather than the amount of air out of the vents.

My car has almost 90k on it, and as it was a company car, I'm guessing it has never been changed unless the servicing dealer took care of it. I've never owned anything new enough to have a cabin filter, so I didn't even realize it might be there. And to think I suffered all winter with heat that never seemed to warm the car up until I'd been driving for 30+ minutes. I'm guessing this is the reason why.

I took mine out in less than 2 minutes and replaced in 5. So it helped a ton. Holly cow my filter was so dirty!!! I made a huge difference with airflow into the car.
This video is incredibly helpful. It's worth taking the 25 minutes to watch it, because his explanations make removal and installation an under-5-minute job. At least, that's how long it took me!

Here's mine after 20,500 miles. About ⅔ suburban/urban city driving, ⅓ highway. Air condition started stinking real bad about a month ago, so I gave the filter a good sniff, and pooo-weee that's nasty! I dunno what was trapped in there, but it's in the garbage now.

ST,please
For the love of god, do not neglect the caf!

So I have had this car a little over a year now and last year I noticed that the warmer that it got (gotta love central TX in the summer), this musty smell would also increase and vice versa during the winter. Now that it's warming up again I decided that I should change the filter. The horror! I don't think the filter has been changed in the entire 47k that this car has had put on. Needless to say I'm getting a new filter today. There were also some leaf parts in there. Where does the ac take outside air from?

Yeah, that's the video I watched to learn the best way to do it. You feel a little weird squeezing the middle but it works real well. It took me about the same time as you when I did mine at 21K miles. I'll do the next one at about 40K as 20K/filter seems about right for my conditions...

block If they had charcoal though, they would be black from Day 1, right?

They all look way too nasty, I agree 100% that there is something going on. I hope the A/C (and/or rain) is not getting them wet and causing mold to grow!!!!

I wonder if aftermarket filters will all turn nasty, (assuming that not all have "charcoal" in them), and in Canada where they do not use A/C as often.

BTW, always turn off your A/C a few minutes/miles before getting home, and keep the fan running (set to a fairly high speed) to warm up and then dry the various airways so humidity doesn't condense in there and get moldy. When you first turn the A/C off, the passageways are very cool, and the warm humid incoming air will probably condense, so the longer the fan is on (w/o AC) the better.

Your engine/intake air filter "breathes" the same air these filters do, and they don't turn black. Why? no active charcoal.
