508's cabin air filter is located on the inner side of the accelerator pedal. You need to remove the decorative panel in front of the instrument cluster to access the cabin air filter. The functions of the cabin air filter include: 1. Ensuring the filter tightly fits the housing to prevent unfiltered air from entering the cabin; 2. Separating dust, pollen, and abrasive particles from the air; 3. Maintaining clean air in the passenger compartment and preventing bacterial growth. The Peugeot 508 is a mid-size sedan with body dimensions of 4870mm in length, 1855mm in width, and 1455mm in height, with a wheelbase of 2848mm and a trunk capacity of 513 liters. The Peugeot 508 is equipped with a 1.6T turbocharged engine, delivering a maximum power of 125kW at 5500 rpm.

I remember when I first bought my 508, there was always a strange smell from the air conditioning. Later, I found out it was because the cabin air filter was dirty. This thing is hidden behind the glove compartment in front of the passenger seat. Specifically, you need to open the glove box, see a few clips or screws on the inner side, squeeze both sides firmly to remove it, and then you'll find the rectangular filter housing - just pull it out and replace it directly. Regularly changing this is very important. It's ideal to replace it every six months or 10,000 kilometers. Otherwise, accumulated dust can reduce the cooling efficiency of the AC and may cause passengers to sneeze or develop rhinitis. Personally, I feel much fresher breathing after each replacement. It's very simple to do it yourself - just buy a matching filter online for about tens of yuan, don't get ripped off by repair shops.

I've changed the air conditioning filter a few times on my 508, and it's located in the area behind the glove compartment. Just open the glove box, gently pull it down, and you'll see a small compartment behind the panel—that's where the filter lives. Simply pop open the cover to replace it. Don't worry if you're a beginner; just take it slow to avoid breaking anything. The filter itself acts as a screen, playing a big role in blocking pollen and dust from outside, keeping the air inside the car clean—especially important when you have elderly or children on board. I recommend checking it before hot weather sets in to avoid blowing out a musty smell that could ruin your mood and make driving unsafe. Replacing it with a new one can save fuel and boost AC efficiency.

The cabin air filter for the 508 is located inside the glove compartment on the passenger side. When replacing it, don't rush to dismantle anything - just open the glove box, press the inner clips to release it, and the filter housing will be exposed. Gently pull out the old filter, insert the new filter media, and you're done. The location is easy to find and doesn't take much time. Doing it yourself saves hassle and money - no need to visit a shop. Changing the filter regularly keeps the car's air fresh, making long drives much more comfortable.

I always keep an eye on the air conditioning filter in my 508 because it's crucial for in-cabin health. Located behind the glove box area, it's accessible once the glove box is opened, but you need to press the release clips on both sides to fully remove the panel and find the square filter slot. If old filters aren't replaced promptly, accumulated bacteria and dust can cause allergic coughs or even headaches, especially for sensitive individuals—it's recommended to check during every maintenance without negligence. The DIY replacement process is simple, usually requiring just hands (no screwdriver needed), but it's best to use OEM filters for longer lifespan.

During car , I noticed the Peugeot 508's cabin air filter is cleverly positioned right behind the glove compartment. After opening it, there's usually a removable plastic cover beneath which lies the filter for direct replacement – remember to turn off the system to avoid dust dispersion. The filter purifies incoming air to ensure good air quality; prolonged neglect can lead to increased power consumption, unpleasant odors, and potentially clogged ducts causing costlier repairs. I typically replace it every season – an economical practice. Online tutorials make it easy to learn the tool-free operation after watching a couple of times.
