Why Doesn't the Wuling Sunshine Have an Air Conditioning Filter?

The Wuling Sunshine is equipped with an air conditioning filter screen instead of an air conditioning filter. The air conditioning filter screen features a concave-convex honeycomb structure, which can be widely used in air filtration and sewage filtration systems. During the spinning stage, antibacterial agents (DEP) and mildew-proof agents (TBZ) are directly incorporated into the PP resin raw material, enabling the produced filter screen to achieve antibacterial and mildew-proof effects. Below is an introduction to the Wuling Sunshine: 1. Basic Introduction: Leveraging the advanced management expertise of SAIC Group and General Motors, combined with Wuling's extensive experience in micro-vehicle manufacturing and collaboration with Hunan University, Liuzhou Wuling independently developed the Wuling Sunshine, a high-tech and high-quality micro-vehicle that meets international safety and environmental standards, launched in 2003. The new protruding front-end design, along with various safety features, ensures that the Wuling Sunshine complies with national safety collision regulations even without airbags. The new 6360 micro-vehicle offers enhanced driving safety, an attractive and stylish appearance, economic practicality, and a spacious interior. 2. Market Overview: On January 18, 2010, SAIC-GM-Wuling, the largest micro-bus manufacturer in China, took the lead by officially launching the new Wuling Sunshine, the upgraded version of the classic micro-bus, in Jinan, targeting the largest mid-range micro-bus market. Yuan Zhijun, Deputy General Manager of SAIC-GM-Wuling, stated that the new Wuling Sunshine, as the company's flagship product for 2010, would drive product upgrades in the mid-range micro-bus market.

I remember the original design concept of the Wuling Sunshine was extreme cost-effectiveness with very strict cost control. The air conditioning system adopted the simplest direct-through external circulation structure, without even reserving a slot for an air filter. For such basic minivans, the core was to meet cargo and passenger transport needs, while air filtration was considered a comfort feature. The newer models have actually been improved, but owners of older versions can only frequently clean the intake grilles. When I ran a repair shop in the village a few years ago, I often helped owners install third-party filter brackets, though it required dismantling the dashboard which was quite troublesome. My suggestion is to simply stuff a sponge filter at the windshield air intake as a temporary solution.

As a veteran driver with ten years of experience behind the wheel of a Wuling, I'm more than qualified to speak on this issue. Back when I bought the car for 50,000 yuan, having an air conditioner that could blow air was already considered a luxury. The manufacturer omitted the filter mainly for three reasons: First, to reduce procurement costs, saving over ten yuan per vehicle on parts; second, to minimize maintenance items, as we mechanics often found that AC ducts without filters accumulated dust much more easily; and lastly, due to space constraints—the engine bay was so cramped that even changing spark plugs was a hassle. Nowadays, all new China VI-compliant models come with filters. For older car owners looking to retrofit, a complete set of filter mesh and brackets can be bought on Taobao for just fifty yuan, and installation takes only half an hour.

From the perspective of vehicle engineering, economical models like the Wuling Zhiguang commonly adopt a negative pressure ventilation system. The AC air intake directly connects to the exterior, eliminating the air filter to reduce airflow resistance and increase air volume—particularly effective for rapid cooling in high-temperature regions. However, the lack of filtration does allow dust to enter the evaporator directly. I've seen Wulings with 80,000 kilometers where the AC system was filled with leaves and poplar fluff upon disassembly. The solution is actually quite simple: monthly vacuum cleaning of the external circulation intake vent below the windshield is more convenient than installing an additional filter.
