How do ceramic fibers affect air quality when used in automobiles and aircraft?

Ceramic fibers, when used in automobiles and aircraft, can positively affect air quality by enhancing the efficiency of emission control systems. These fibers are often used in the construction of catalytic converters and filters, which help to reduce harmful pollutants such as carbon monoxide, nitrogen oxides, and particulate matter. By increasing the surface area for chemical reactions to occur, ceramic fibers facilitate the breakdown of these pollutants into less harmful substances, thereby improving air quality both inside and outside the vehicle. However, it's important to note that the manufacturing and disposal of these fibers can pose environmental challenges, and proper management is crucial to minimize any negative impacts.
