The method for replacing the cabin air filter in a Discovery 4: The cabin air filter is located behind the glove compartment on the passenger side. Pull out the two retaining pins beneath the glove compartment, remove the cover plate, and you will see the cabin air filter. Take out the old filter, install the new one, and then reattach the cover plate. The Discovery 4 is a model developed by Land Rover, and its body-on-frame construction indicates that it is a true ORV (Off-Road Vehicle) with robust off-road capabilities. The front grille features a hollowed-out design, giving it a more stylish appearance. The dimensions of the Land Rover Discovery 4 are 4838mm in length, 2022mm in width, and 1882mm in height, with a wheelbase of 2885mm.
Replacing the air conditioning filter on a Land Rover Discovery 4 is a straightforward DIY job. I always do it myself—just make sure you have the correct replacement filter ready. First, empty the glove compartment on the passenger side, then press the clips on both sides inward to gently lower the glove box. Behind it, you’ll see the rectangular plastic cover for the filter. Press the clip to remove it. Pull out the old filter, noting the arrow direction (indicating airflow). Install the new filter in the same orientation—don’t reverse it. When reattaching the cover, align it carefully and snap it into place. The whole process takes about 10 minutes. I recommend wearing gloves to keep your hands clean. Regularly replacing the filter ensures fresh airflow and benefits respiratory health. Change it annually or more frequently if you often drive in dusty areas.
I believe replacing the cabin air filter is crucial for driving health and system safety. Based on my experience, the Discovery 4's cabin air filter is located behind the glove box. The first step is to empty the glove box to prevent items from falling out. When removing the glove box, carefully press the clips on both sides with proper technique – avoid using excessive force to prevent damaging plastic components. After removing the filter cover, be sure to note the installation direction of the old filter. The arrow indicator on the new filter must align with the original orientation. During installation, ensure the filter edges aren't folded, as this affects sealing performance. After replacement, test the AC system to check airflow and detect any unusual odors. I also recommend using genuine filters, as inferior products may cause dust accumulation in the blower motor. Replace every 10,000 km or annually, and more frequently in areas with poor air quality. This effectively filters pollen and dust, protecting your family's respiratory health.
