Automotive filters play a crucial role in the operation of modern vehicles, as they purify the air and oil entering the engine, preventing dust, particles, and pollutants from causing damage. One of the core components of these filters is the filter paper, which plays a vital role in the filtration process. This article will delve into the differences and functions of automotive filter paper, as well as the impact of its permeability and folding on the product.

Function and Types of Filter Paper

Filter paper is a key component of filters, designed to capture and isolate small particles and pollutants from air or liquids. In automotive filters, filter paper is used in two main applications: air filters and oil filters.

Air Filter Paper: Air filter paper is used to prevent particles and pollutants in the air from entering the engine. Unlike oil filters, air filters require higher permeability to ensure the engine receives sufficient fresh air. They must effectively capture dust, pollen, insects, and other small particles.

Oil Filter Paper: Oil filter paper is tasked with removing impurities from engine oil to maintain its purity. Oil filter paper needs to handle high-viscosity liquids, so it is typically more dense.
