The cabin air filter in a Land Rover Discovery 4 is located inside the glove compartment on the passenger side. Simply remove the glove box clips and pull it out to access the filter. The cabin air filter helps absorb dust particles, alleviates respiratory discomfort, reduces irritation for allergy sufferers, and enhances driving comfort while also protecting the vehicle's air conditioning cooling system. Taking the 2020 Land Rover Discovery 4 as an example, it features a 5-door 7-seat SUV body structure with dimensions of 4956mm in length, 2073mm in width, and 1888mm in height. It has a wheelbase of 2923mm, front track of 1692mm, rear track of 1687mm, a fuel tank capacity of 90 liters, and a curb weight of 2330kg.

I've driven this car for several years, and the location of the cabin air filter is near the passenger footwell. You'll need to open the glove compartment or remove the side panel to access it. Before opening the glove box, it's best to empty its contents first, then press the clips on both sides and gently pull to remove it. The filter is housed in a small compartment behind, usually encased in a black or white plastic frame. When replacing, make sure the model matches—the OEM version is a HEPA high-efficiency filter, though cheaper universal alternatives are available in the market. I recommend replacing it every 12 months or 10,000 km, as accumulated dust can degrade cabin air quality and trigger allergies over time. DIY replacement requires a small Phillips screwdriver and some patience—first-timers may spend around 20 minutes, saving ¥100–200 in labor costs at a repair shop. After installation, test the AC airflow to ensure proper fitment.

As an enthusiast who frequently maintains these models, the air conditioning filter of the Land Rover Discovery 4 is hidden above the passenger footwell, and it can be found by removing the glove box. The specific steps are: first remove the screws or clips, then take off the glove box panel, and the filter is fixed in a rectangular slot behind it. Made of fiber cotton, it effectively filters pollen and pollutants. I remind everyone to pay attention to the replacement timing—if the airflow weakens or there's an odd smell, it's time for a change. DIY replacement requires basic tools like a screwdriver and takes about ten minutes; professional shops may charge but offer more convenience. Long-term neglect not only worsens air quality but may also clog ducts, leading to higher repair costs. Keeping this component clean is crucial for the overall performance of the air conditioning system.

Let me briefly explain. The cabin air filter is located on the passenger side, near the carpet area. Open the glove compartment, remove several clips or screws, and you'll find the filter in a small slot behind it. Before installing a new filter, double-check the size and orientation to avoid incorrect installation. It's recommended to use OEM models to ensure optimal performance. Generally, it's advised to replace it once a year - when too old, accumulated dust can make the cabin air unpleasant. It's quite simple to DIY, requiring only basic tools like a screwdriver. Even beginners can easily complete the task by following instructional videos or manuals.
