Dongfeng Fengshen AX7's cabin air filter is located inside the glove compartment on the passenger side. Here are situations when the cabin air filter needs replacement: Unpleasant odors inside the vehicle: After cleaning or deodorizing the interior, if strange smells persist or the air remains stale, consider replacing the cabin air filter. After driving 20,000 kilometers: It's recommended to replace the cabin air filter after 20,000 kilometers. In areas with poor air quality (frequent sandstorms or smog), replacement may be needed as early as 10,000 kilometers. Generally, the filter should be replaced every 7,000 to 10,000 kilometers. In severely polluted environments, earlier replacement is advised. The product's effectiveness is typically guaranteed within these mileage ranges.

I recently replaced the air conditioning filter on my AX7 by myself, which is located behind the glove compartment on the passenger side. You need to remove the glove compartment first—there are clips on both sides that can be easily pressed to release it. Inside, you'll see a plastic cover; pry it open to access the filter slot. The design is quite user-friendly, making it easy to insert and remove the filter. When a new filter, remember to choose one with activated carbon to help eliminate odors. I usually replace it every six months, but with the recent heavy smog, I've been changing it every three months. After replacement, there's a noticeable improvement in the air quality inside the car. Doing it myself saved a lot of money—the labor cost at a shop is enough to buy two filters. Just remember to install the filter with the arrow pointing downward; otherwise, it affects the filtration efficiency. I installed it upside down the first time.

As an AX7 owner, I find changing the air conditioning filter quite simple. Open the glove compartment on the passenger side, lift it slightly to release the stopper, and the entire glove box can be removed. The air filter cover is inside, which can be gently pried open with a plastic pry tool, and the old filter can be pulled out directly. Although the location is somewhat hidden, it's not difficult to operate. Last time I changed the filter, I found the old one full of leaves and dust—no wonder there was a dusty smell when the AC was on. I recommend replacing it every 10,000 kilometers or every season, especially in dusty northern areas like ours. the filter online is very cheap, costing only about 20 yuan, much more economical than at a 4S shop. The whole process takes less than ten minutes and is easy enough for women to handle.

Last month at the repair shop, I saw the technician replacing the AX7's cabin air filter, located behind the glove compartment on the passenger side. First, empty the glove compartment and firmly press both sides to release it from the clips, revealing a rectangular cover for the cabin air filter. Be careful not to break the plastic clips when prying open the cover. The old filter often comes out blackened, and it's recommended to replace it every six months. Many people wait until there's a foul odor before changing it, but actually, you should check it when the airflow from the AC decreases. If you're doing it yourself, remember to turn off the AC before starting to avoid debris falling into the air ducts. It's best to choose an OEM or compatible filter, as I've seen low-quality filters deform and get stuck. This location is much more convenient for replacement compared to some German car designs where it's in the engine compartment.

After driving the AX7 for five years, I've long figured out where the cabin air filter is located. It's behind the long plastic cover panel in the glove compartment on the passenger side. To remove it, first empty the glove box, then squeeze both sides towards the center and pull down to detach the entire glove box. The filter compartment cover has clips that can be pried open with just your fingernail. The filter location in this car is much easier to find compared to older Japanese models. I recommend choosing a dual-layer composite filter - the first layer blocks dust while the second layer eliminates odors. I replace it every 8,000 kilometers, as suggested by the manual. When replacing it yourself, be careful not to let foreign objects fall into the air ducts and ensure the filter isn't installed backwards. Last time after replacement, I immediately noticed stronger airflow from the AC and much better breathing comfort.
