What Are the Hazards of Using Low-Quality Car Window Films?
2 Answers
The hazards of using low-quality car window films include: reduced clarity and failure to meet light transmittance standards. There are specific regulations for the light transmittance of front windshield films, which must not be less than 70%. If the front windshield's light transmittance is too low, it can impair the driver's ability to see road conditions clearly. Some low-quality films not only fail to meet light transmittance standards but also have poor clarity, which can negatively impact the driver's safety. The functions of car window films are: 1. To provide heat insulation in summer, saving on air conditioning energy; 2. To reduce energy loss in winter, maintaining the interior temperature; 3. To block ultraviolet rays, extending the lifespan and quality of interior furnishings; 4. To reduce glare, ensuring safe and comfortable driving.
Last time I tried to save money by installing a cheap, low-quality car film, but problems emerged quickly. Bubbles kept appearing, distorting my vision while driving, especially in low-light conditions where it became extremely blurry. The eye strain was unbearable, and I nearly scraped objects several times. Even worse, the poor-quality film material emitted a pungent odor that wouldn’t dissipate even with the AC on. Prolonged exposure caused dizziness and nausea, raising health concerns. The film deteriorated fast, fading and peeling within half a year—not only looking shabby but also failing to provide privacy, as outsiders could easily see inside. Trying to save money backfired, forcing me to spend more on reinstallation. The biggest risk was compromised driving safety—poor visibility could lead to accidents. So I strongly advise against cutting corners here; investing in a reputable, high-quality film is the smart long-term solution.
