Where is the cabin air filter located in the Citroën C4?

Citroën C4's cabin air filter is located in the engine compartment, beneath the windshield on the front passenger side. Removing the sound insulation pad will reveal the cabin air filter. The cabin air filter purifies incoming air by filtering out impurities such as fine particles, pollen, bacteria, industrial exhaust, and dust, thereby protecting the air conditioning system. The Citroën C4 is an MPV model under the Citroën brand, with a wheelbase of 2,785 mm and dimensions of 4,428 mm (length) × 1,826 mm (width) × 1,629 mm (height).

I've been driving my Citroën C4 for several years now, and I know the location of the air conditioning filter like the back of my hand—it's right behind the glove compartment on the passenger side. The process is quite straightforward. First, open the glove box and empty its contents, then locate the clips or screws at the bottom. A gentle press or twist will allow you to remove the entire glove box. Behind it, you'll find a small rectangular cover. Remove this, and the air conditioning filter will be tucked inside. I was a bit nervous the first time I replaced it myself, but after following a tutorial video, I had it done in under ten minutes. Remember to choose the correct filter model for your car—buying online is very cost-effective. I recommend replacing it every six months, or more frequently if you drive in dusty areas. After installing a new filter, the air inside the car becomes noticeably fresher, and the AC cools more efficiently, saving you the hassle and expense of frequent trips to the repair shop.

As someone who works with these cars year-round, I find the location of the Citroën C4's cabin air filter quite well-designed—it's tucked inside the glove compartment on the passenger side, slightly toward the rear. Replacing it doesn’t require any special tools; just a simple screwdriver or even your fingers to pop open the panel at the bottom of the glovebox. The filter itself isn’t immediately obvious, but once located, inspecting it is straightforward. If clogged with excessive dust, it can severely degrade cabin air quality, triggering allergies or unpleasant odors. I’ve encountered owners who mistakenly searched for the filter in the engine bay, wasting time and effort. So, during routine maintenance, pay extra attention to this detail and replace it seasonally—like during spring when pollen is high or the rainy season when humidity spikes. Developing this habit ensures smoother AC operation and saves unnecessary expenses on professional inspections.

Changing the air conditioning filter on my Citroën C4 by myself was incredibly satisfying. It's located behind the glove compartment on the passenger side. I opened the glove box, pressed down the clips at the corners to remove it, and saw a white plastic cover holding the filter. The steps are simple: prepare a new filter, unscrew the cover, and insert the new one. The whole process took less than ten minutes, saving me dozens of dollars in maintenance fees. It's recommended to replace it every six months to keep the air conditioning system healthy.
