Ceramic fibers improve filter performance through their unique properties. They are highly resistant to heat and chemical corrosion, which allows them to operate effectively in harsh environments. Their small diameter and high surface area provide a large number of contact points for particulate matter, enhancing filtration efficiency. Additionally, ceramic fibers can be engineered to have a specific pore size distribution, which allows for precise control over the size of particles that can pass through the filter. This customization, combined with their durability and ability to withstand high temperatures, makes ceramic fibers an excellent choice for improving filter performance in various applications.
