Citroen C-Quatre's air conditioning filter is located in the engine compartment under the wiper cover panel. Remove the insulation cotton to see it. Here is some information about car air conditioning filters: 1. The air conditioning filter is located at the rear of the glove compartment on the passenger side. First, open the glove compartment cover, then find a fixed buckle on the right side of the glove compartment and pull it outward with force. Remove the fixed buckle of the glove compartment cover panel, squeeze both sides of the glove compartment towards the middle with both hands, then lift it outward to remove the glove compartment. 2. The function of the car air conditioning filter is to ensure that as little unfiltered air as possible enters the cabin, to absorb harmful substances and moisture in the air, and to filter solid impurities such as dust, pollen, and grinding particles in the air. It ensures clean air in the passenger compartment without breeding bacteria, effectively intercepts pollen, and ensures that drivers and passengers are not affected by allergies that could compromise driving safety.

I know exactly where the air conditioning filter for the Citroen C-Quatre is located - it's mainly behind the glove compartment in front of the passenger seat. First, you need to open the glove box door, where there's usually a small cover or clip. After prying it open, you'll see the filter housing. Last time I replaced it myself, it only took about ten minutes. Just prepare a simple T20 screwdriver or hand tools, and avoid pulling too hard to prevent damaging the plastic. The filter should be replaced regularly, ideally once a year, especially if you drive a lot in dusty urban areas. After replacement, the air inside the car immediately becomes fresher, making breathing much more comfortable. If you can't find it, some older models might have it near the windshield wiper tray under the hood, but most C-Quatre models have it in the glove compartment.

As a car enthusiast, I've noticed that the cabin air filter for the Citroen C-Quatre is mostly located behind the inner wall of the glove compartment on the passenger side. After opening the compartment door, feel along the bottom or side interior - there's a plastic cover panel that can be pried open to reveal the filter housing. No special tools are needed; you can manually pop it open or use a flathead screwdriver for assistance. Remember to prepare a new filter before replacement - either activated carbon or standard version will do, costing only 20-30 RMB with very low maintenance cost. Normally it should be replaced every 12 months to prevent cabin odors and dust accumulation, while also extending the AC system's lifespan. After installation, start the engine to check if air vents are functioning smoothly, ensuring that DIY satisfaction.

It was my first time changing the air conditioning filter for my Citroën C-Quatre (C-Elysée), and after some exploration, I found its location inside the glove compartment on the passenger side. Upon opening it, I noticed a small clip or flap, which I gently pushed aside to reveal the filter. Replacing it with a new one was quite straightforward. It took me some time to familiarize myself with the structure, but I managed to do it without any tools. The filter size is standard, approximately 20x20 cm, so make sure to confirm the model before purchasing. Normally, replacing it once a year is sufficient, but if you drive in dusty urban areas, you might want to do it more frequently to keep the cabin air fresh, which makes for a more pleasant driving experience.
