The cabin air filter in the Dongfeng Fengshen AX7 is located behind the glove box on the passenger side. The functions of the cabin air filter are: 1. Providing fresh air; 2. Absorbing harmful substances; 3. Filtering solid particles. Taking the 2021 Dongfeng Fengshen AX7 as an example, it belongs to the compact SUV category with body dimensions of: length 4645mm, width 1880mm, height 1670mm, wheelbase 2715mm, and fuel tank capacity 61L. The 2021 Dongfeng Fengshen AX7 features MacPherson strut front suspension and double-wishbone rear suspension. It is equipped with a 1.5L turbocharged engine delivering maximum power of 150PS (110kW) and peak torque of 230Nm, paired with a 6-speed manual transmission.

I remember replacing the air conditioning filter on my AX7 by myself—it's hidden behind the glove compartment on the passenger side. First, empty all the items from the glove box, then locate the clips on both sides of the box. Squeezing them inward firmly will release the box. Behind it, you’ll find a rectangular plastic cover, usually marked with an "UP" arrow. Press the clip and gently lift the cover to slide out the filter like a drawer. When replacing, make sure the arrow on the new filter aligns with the original direction; otherwise, the filtration efficiency could be affected. Last time I changed it, the filter was completely black—no wonder the AC had a musty smell. DIY jobs like this can be a bit tedious, but they save you over a hundred bucks in labor costs.

As someone who often helps friends with car repairs, the location of the AX7's cabin air filter is actually quite typical. It's located in front of the blower behind the glove compartment on the passenger side, and you'll need to remove the glove box to access it. First, release the limiters on both sides of the glove box and pull the entire glove box downward to remove it. The black plastic cover inside can be opened by prying the clips with your fingers, and the filter frame you remove is about 15 cm wide. Pay special attention to the factory filter's orientation—the side with the foam sealing strip should face upward; installing it backward can cause air leaks. This type of filter generally needs replacement every 20,000 kilometers or once a year, but if you frequently drive on dusty roads, you should replace it earlier. Before starting, it's best to watch a replacement video on car enthusiast forums to feel more confident.
