  Cellulose fiber air filters use a natural material called cellulose. Cellulose is found in plant cell walls, especially in wood and cotton. The cellulose used in these filters is carefully processed and cleaned, so it is safe and effective for filtering. These filters effectively trap dirt and particles due to the structure of cellulose fibers. The fibers create a sticky web that catches debris as air flows through, preventing it from entering sensitive engine parts. While cellulose filters provide good performance, they may need more maintenance than synthetic options. Foam air filters generally require regular cleaning and oiling to ensure optimal airflow and filtering.

• Synthetic fiber air filters

  Synthetic fiber air filters are made from man-made materials like polyester. Polyester is a common material used in clothing, but in filters, it is designed differently for better filtering. The use of synthetic fibers allows for precise control over properties like pore size and fiber density. This results in filters with tailored features for optimal air flow and contaminant capture. Synthetic fiber filters excel in high-performance applications. They effectively filter out small particles without significantly restricting airflow, ensuring engines receive abundant air for power output. This is crucial for high-performance engines that rely on optimal air intake for peak performance. Additionally, synthetic materials offer durability and resistance to environmental factors, ensuring consistent filtering efficiency even in demanding conditions.
