To replace the cabin air filter in a GS4, first remove the upper clips, then proceed to remove the lower clips. After removing the glove box, you will see the cabin air filter cover. Similarly, remove the air filter cover. The old original cabin air filter will be visible; simply pull it out. Finally, install the new cabin air filter, ensuring the model matches. The functions of the cabin air filter include the following 5 points: 1. It ensures the filter fits tightly against the housing, preventing unfiltered air from entering the cabin. 2. It separates solid impurities such as dust, pollen, and abrasive particles from the air. 3. It adsorbs moisture, soot, ozone, odors, carbon oxides, SO2, CO2, etc., from the air, providing strong and long-lasting moisture adsorption. 4. It supplies fresh air to the passenger compartment, preventing occupants from inhaling harmful gases, ensuring driving safety, and effectively sterilizing and deodorizing. 5. It maintains clean air in the passenger compartment, preventing bacterial growth and creating a healthy environment.

As a seasoned GS4 driver for several years, I'm quite familiar with changing the cabin air filter. First, open the glove compartment in front of the passenger seat, noting there are clips or screws on both sides - gently pry them open or unscrew them. Then pull out the filter cover; the old filter might be clogged with dust, so remove it carefully and don't forget to check the arrow direction. When installing the new filter, make sure to align the direction correctly to avoid reduced filtration efficiency. I've done this several times myself - it takes just minutes and saves me about a hundred bucks at repair shops. Pro tip: replace it every six months or 10,000 km to prevent musty AC odors from harming your lungs. All you need are gloves and a screwdriver - be careful not to break the clips. After replacement, test if the airflow from vents feels smoother.

I'm an enthusiast who enjoys changing the GS4's cabin air filter myself, and it gives me a great sense of accomplishment. The first step is to crouch down and locate the position below the glove box, where there's usually a plastic cover. Just unclip the fasteners to remove it. The old filter is typically black and dusty—shake it, and dust will fall off. After taking it out, clean the slot thoroughly. When installing the new filter, make sure the letters or arrow face the direction of the car's windshield to avoid installing it backward. The first time I replaced it, I forgot about the orientation, and the airflow became much weaker. All you need is a Phillips screwdriver, and buying the filter yourself costs just a few dozen bucks, saving money compared to a shop. Additionally, frequent filter changes help maintain good air quality inside the car, preventing dry and itchy throats when using the AC. I recommend replacing it once each in spring and autumn.

Replacing the GS4's cabin air filter is actually quite simple, and I often do it myself. Open the glove compartment on the passenger side; there might be a small cover inside or underneath—just remove it directly. Pull out the old filter and discard it, being careful not to let any fragments fall. When installing the new filter, pay attention to the arrow indicator—it should point toward the front of the car to avoid misalignment. The whole process takes just a few minutes, and I do it myself every time to save money and have peace of mind. I recommend using a high-quality filter to prevent clogging the air conditioning. After replacement, test the AC—the airflow should be stronger and cleaner.

As a car enthusiast, I'd like to share the steps for replacing the GS4's cabin air filter: First, empty the glove compartment and locate the small filter compartment cover, which can usually be unclipped with your fingers. When removing the old filter, do it gently to avoid damaging the frame, then insert the new filter ensuring the correct orientation—the arrow should point toward the windshield. While replacing mine, I noticed a lot of dust, so I took the opportunity to vacuum the slot. This can actually help save fuel as a clean filter improves efficiency. All you need is a screwdriver, and the filters are cheap to buy online. I recommend checking it every season—installing it backward can cause noise, and you'll immediately notice fresher air inside the car after replacement.

I've changed the GS4's cabin air filter several times, and it's quite easy to handle. Start from the glove box, remove the cover to take out the old filter—it might be very dirty, so just replace it directly. Remember to align the arrow on the new filter with the direction the car moves forward to avoid installing it backward. Doing it yourself only takes some time and attention, and the filter costs just over ten yuan. The benefits include longer-lasting AC and fewer odors; it's recommended to replace it every six months to prevent allergies. A screwdriver is all the tool you need, but be careful not to use excessive force and damage the parts. After finishing, test to see if the cooling effect improves.
