What's the Difference Between Good and Bad Car Air Filters?
2 Answers
The differences between good and bad car air filters are as follows: 1. Filter Paper: A good air filter has uniformly colored filter paper with a flat surface and more fibers on the windward side, providing better filtration and trapping more impurities; whereas a poor-quality air filter has inferior filter paper with a smoother surface. 2. Structure: A good air filter features hard plastic reinforcement ribs to effectively prevent filter paper deformation; a poor-quality air filter uses a one-piece molded structure without any reinforcement measures, making it prone to deformation. 3. Number of Folds: A good air filter has more folds in the filter paper, increasing the filtration area and improving efficiency. In contrast, a poor-quality air filter has fewer folds, resulting in lower filtration efficiency.
When it comes to the difference between good and bad car air filters, I’ve learned from my driving experience that high-quality filters use premium materials to efficiently filter out air impurities like dust and pollen, allowing the engine to smoothly intake clean air. This improves fuel combustion efficiency, saves fuel consumption, and protects the engine from wear. On the other hand, poor-quality filters may clog or use inferior materials, restricting airflow and making the engine work harder, leading to reduced power and potential disruptions in the electronic control system. They can also cause excessively high intake temperatures. For example, after I installed a low-quality filter, I noticed increased carbon buildup on the spark plugs within a few months, which cost me a lot in repairs. In the long run, regularly replacing your air filter with a good one can reduce maintenance costs and avoid major engine overhauls. I recommend choosing branded filters and checking them every 10,000 kilometers.
