Song MAX air conditioning filter is located under the glove box on the passenger side. Open the glove box cover, push the lever to the right to remove it, then take off the glove box to reveal the air conditioning filter housing cover. Open the cover to access the air conditioning filter. The air conditioning filter is a component installed in the car's air conditioning system that absorbs dust particles, reduces respiratory discomfort, minimizes irritation for allergy sufferers, and protects the air conditioning cooling system. Taking the 2021 BYD Song MAX as an example, it belongs to the MPV category with body dimensions of: length 4710mm, width 1810mm, height 1680mm, wheelbase 2785mm, and a fuel tank capacity of 60 liters.

When I drove the Song MAX before, I also wondered where the cabin air filter was located. It's behind the glove compartment on the passenger side, and you'll need to remove the glove box first to access it. After opening the glove box, firmly press the clips on both sides of the inner compartment to easily detach the entire glove box. The filter sits in a rectangular slot at the back, and you can remove it by pressing the clips on the cover plate. I recommend checking it every six months, especially during spring in northern regions when willow catkins are abundant. Buying compatible filters online only costs about 30-40 yuan, saving you over a hundred yuan in labor fees compared to visiting a 4S shop. It's also a good opportunity to check if there's dust accumulation in the air ducts.

As a Song MAX owner, I find the design of the air filter location quite user-friendly. Open the glove compartment on the passenger side, press both hands against the sides of the compartment and push inward until you hear a click, indicating the stopper has been released. After removing the glove compartment, you'll see a cover plate with an arrow indicator—the air filter is inside. Remember to install the new filter in the direction of the arrow. I usually replace it before the rainy season, as using the external air circulation on rainy days can lead to a musty smell. Nowadays, a filter from the flagship store on Taobao even comes with an installation toolkit, and you can get the job done yourself in just twenty minutes.

Last week, I just helped my neighbor replace the air conditioning filter for the Song MAX. It is located behind the glove box, and the entire glove box needs to be removed during the operation: after opening the box, push inward on both plastic walls to release the limit clips, and then it can be taken out. The filter is hidden behind a long strip cover, and it can be replaced by gently prying the clips with a screwdriver. A special reminder is to wear gloves during the operation, as some old filters may accumulate dust and mold spots. The filter's position is low, making it easy for leaves to fall in, so it's best to have a flashlight ready for the operation.

The air filter of the Song MAX is located behind the glove compartment on the passenger side. The most crucial step in replacing the filter is removing the glove compartment: press both sides of the compartment inward with your hands to release the sliding rails from the limit grooves. Once the glove compartment is removed, you can see the filter slot. I usually replace the filter every two seasons, always before the summer and winter transitions. When installing a new filter, make sure the moisture-proof layer of the filter paper faces downward; installing it upside down can cause deformation. It's best to prepare a vacuum cleaner before starting, as dust shaken off from the old filter can easily spread all over the car.

Last year I started learning to replace the cabin air filter for my car. The Song MAX's filter is easy to locate behind the glove box. First, remove the glove box: after opening it, squeeze the inner walls on both sides inward to release the stoppers, and the entire box will drop down. The filter cover behind has two clips at the top and bottom, which can be opened by pressing with your thumb. It's advisable to wear a dust mask when replacing the filter, especially for old filters that have been in use for two years. It's best to install a new one before using the air conditioning in summer to prevent musty odors. Doing it yourself saves time compared to visiting a 4S shop—no need to make an appointment or wait in line. Once you get the hang of it, the whole process can be done in just ten minutes.
